Great efforts have been made to locate wireless devices, especially to support the Federal Communications Commission's (FCC) rules for Enhanced 911 (E911) Phase II. (The Wireless Improved 911 (E911) Regulation aims to increase the effectiveness and reliability of wireless 911 services by providing 911 callers with additional information about wireless 911 calls. The Wireless E911 Program has two It is divided into parts, Phase I and Phase II. Phase 1 is the telephone number of the wireless 911 caller and the telephone number of the wireless 911 caller when a valid request is received by the Public Safety Answering Point (PSAP). Require carriers to report the location of the antenna that received the call. Phase II requires wireless carriers to provide more accurate location information, often within 50 to 300 meters. The deployment of E911 required the development and upgrade of new technologies for local PSAP, etc. In Phase II of E911, the FCC directive was a circular error probability. Position detection request accuracy based on (circular error probability) was included. Network-based systems (wireless location detection systems that collect radio signals at network receivers) meet 67% accuracy of callers within 100 meters and 95% accuracy of callers within 300 meters. Was required. Handset systems (wireless location detection systems that collect radio signals at mobile stations) are required to meet 67% of callers within 50 meters and 95% of callers within 100 meters. It was. Wireless carriers were allowed to adjust the accuracy of location detection in the service area, so they could not guarantee the accuracy of any given location estimation.
Some considerations, such as accuracy and yield (number of successful call position detections), were specified by the FCC for a single LBS service in E911, but latency (requester or selected application). Other quality of service (QoS) parameters such as location elucidation and delivery of location estimates) were not specified. The FCC was concerned about accuracy in certain cases when calling a cellular call to an emergency service center (911 center or PSAP). The current state of the art and the FCC's rigorous accuracy standards have limited the choice of technology for widely deployed position detection technologies. Network-based options for E911 Phase II included uplink arrival time differences (U-TDOA), arrival angles (AoA), and TDOA / AoA hybrids. Non-network-based position detection options for Phase II 911 include Navista Global-Earth augmented with data from land-side servers, including synchronization timing, orbital data (Ephemeris), and capture data (code phase and Doppler range). Included was the use of a geographic system (GPS).
In addition to the FCC E911 compliant position detection system for wireless voice communication, other wireless devices that use arrival time (TOA), arrival time difference (TDOA), arrival angle (AoA), arrival power (POA), and arrival power difference. Location detection systems can also be used to develop location detection that meets the requirements of a particular location-based service (LBS).
The following detailed description chapters provide background information on location detection techniques and wireless communication systems that can be used with the present invention. The rest of this background chapter provides additional background information about wireless location detection systems.
Early work on wireless location detection systems can be found in US Pat. No. 5,327,144, dated July 5, 1994, entitled "Cellular Telephone Location System." It discloses a system for detecting the location of cellular phones using the arrival time difference (TDOA) technique. Further improvements to the system disclosed in the '144 patent are in US Pat. No. 5,608,410, dated March 4, 1997, entitled "System for Locating a Source of Bursty Transmissions." It is disclosed. Both of these patents have been assigned to True Position, Inc., the assignee of the invention. TruePosition continues to develop significant improvements to the original concept of invention.
Over the past few years, the cellular industry has seen an increase in the number of air interface protocols available for use by wireless phones, as well as the number of frequency bands in which wireless or mobile phones can operate, "personal communications services." The number of terms referring to or related to mobile phones, including, "wireless", etc., is also increasing. Air interface protocols currently used in the wireless industry include AMPS, N-AMPS, TDMA, CDMA, GSM, TACS, ESMR, GPRS, EDGE, UMTS WCDMA and the like.
The value and importance of wireless location detection systems has been recognized by the wireless communications industry. In June 1996, the Federal Communications Commission issued a request to the wireless communications industry to deploy a location detection system for use in location detection of wireless 911 callers. Widespread deployment of these systems reduces the use of emergency response resources, reducing emergency response times, saving lives and saving enormous costs. In addition, research and research have concluded that various wireless applications such as location sensitive billing, owned vehicle management, etc. will have significant commercial value in the coming years. ..
As mentioned above, a number of air interface protocols are used in wireless communication systems. These protocols are used in different frequency bands, both in the United States and abroad. Neither the air interface nor the frequency band generally affects the effectiveness of the wireless location detection system in the location detection of wireless phones.
All air interface protocols use two types of "channels". Here, a channel is defined as one of a large number of transmission paths within a single link between points in a wireless network. The channel can be defined by frequency, bandwidth, synchronized time slots, coding, shift keying, modulation scheme, or any combination of these parameters. The first type, also called a control or access channel, is used to convey information about a wireless phone or transmitter to start and end a call, or to transfer burst data. For example, some short messaging services transfer data through control channels. Different air interfaces identify control channels by different terms, but the functions of the control channels in each air interface are similar. The second type of channel, also known as a voice or traffic channel, is typically used to carry voice or data communications through an air interface. The traffic channel is put into use once the call is set up with the control channel. Voice and user data channels typically use dedicated resources within wireless communication systems, i.e., this channel can only be used by one mobile device, while control channels use shared resources. That is, this channel can be accessed by a large number of users. Voice channels generally do not have identifying information about the wireless phone or transmitter in the transmission. For wireless position detection applications, this distinction may also allow the control channel to be used most cost-effectively for the purpose of wireless position detection rather than the use of voice channels. However, depending on the application, position detection on the voice channel may be desired.
Some of the differences in the air interface protocol are discussed below.
AMPS-This is the original air interface protocol used for cell communication in the United States and is described in the TIA / EIA standard IS-553A. The AMPS system allocates a separate dedicated channel for use by the control channel (RCC). These are defined by frequency and bandwidth and are used for transmission from the BTS to the Mobile Phone A Reserved Voice Channel (RVC), for transmission from the Mobile Phone to the BTS, and which are not assigned to the control channel. It can also occupy the channel.
N-AMPS-This air interface is an extension of the AMPS air interface protocol and is specified in the EIA / TIA standard IS-88. It uses essentially the same control channels as in AMPS, but uses different audio channels with different bandwidths and modulation schemes.
TDMA-This interface, also known as D-AMPS, is specified in the EIA / TIA standard IS-136 and features both frequency separation and time separation. A digital control channel (DCCH) is transmitted in burst mode to an allocated time slot that can occur anywhere in the frequency band. A digital traffic channel (DTC) can occupy the same frequency allocation as a DCCH channel, but cannot occupy the same time slot allocation in a given frequency allocation. In the cellular band, carriers can use both AMPS and TDMA protocols as long as the frequency allocation for each protocol is separated.
CDMA-This air interface is specified in the EIA / TIA standard IS-95A and features both frequency separation and code separation. Since adjacent cell sites may use the same frequency set, CDMA must operate under very careful output control, and this careful output control is a problem for those skilled in the art. A situation arises known as, which makes it difficult for most methods of radiolocation to perform accurate location detection (although a solution to this problem is described in US Pat. No. 6,047,192, April 4, 2000, Robust, Efficient, Localization System (see Robust and Efficient Localization System). Control channels (known in CDMA as access channels) and traffic channels can share the same frequency band, but are separated by code.
GSM-This air interface is defined by the international standard Global System for Mobile Communications and features both frequency and time separation. GSM distinguishes between physical channels (time slots) and logical channels (information transmitted by physical channels). Several regression timeslots on the carrier are used by different logical channels to form a physical channel and transfer both user data and signaling information.
The control channel (CCH) includes a broadcast control channel (BCCH), a common control channel (CCCH), and a dedicated control channel (DCCH), and is transmitted in bursts in the time slot assigned for use by the CCH. CCH can be assigned anywhere in the frequency band. The traffic channel (TCH) and CCH can occupy the same frequency allocation, but cannot occupy the same time slot allocation in a given frequency allocation. CCH and TCH use the same modulation scheme known as GMSK. To improve the data rate of GSM General Line Radio Service (GPRS) and GSM Evolution (EDGE) systems, reuse the GSM channel structure, but use multiple modulation schemes and data compression to increase data throughput. be able to. GSM, GPRS, and EDGE radio protocols are incorporated into a classification known as GERAN or GSM Edge radio access networks.
UMTS-Precisely known as UTRAN (UMTS Terrestrial Radio Access Network), it is an air interface defined by the International Standards Third Generation Partnership Program as the successor to the GERAN protocol. UMTS, sometimes known as WCDMA (or W-CDMA), means wideband code division multiple access. WDCMA is a direct spreading technology, which means spreading its transmission across a wide 5MHz carrier.
WCDMA FDD (Frequency Division Duplication) UMTS Air Interface (U-Interface) separates physical channels by both frequency and code. WCDMA TDD (Time Division Duplex) UMTS Air Interfaces separate physical channels by the use of frequency, time, and sign. All variants of the UMTS radio interface include logical channels, map them to transport channels, and then map the transport channels to W-CDMA. Map to an FDD or TDD physical channel. Since adjacent cell sites may use the same frequency set, WCDMA also uses very careful output control to address the near-far problem common to all CDMA systems. Control channels in UMTS are known as access channels, while data or voice channels are known as traffic channels. Access and traffic channels can share the same frequency band and modulation scheme, but are separated by code. As used herein, reference to control and access channels or voice and data channels in general refers to all types of control channels or voice and data channels, whatever the preferred term for the individual air interface. Will be targeted. Moreover, there are many more types of air interfaces used around the world (eg IS-95). CDMA, CDMA2000, UMTS, and W-CDMA) do not exclude any air interface from the inventive concepts described herein. Those skilled in the art will appreciate that other interfaces used elsewhere are derivatives of those described above or of similar classes.
<p> GSM networks pose a number of potential issues with existing wireless location detection systems. First, wireless devices connected to GSM / GPRS / UMTS networks rarely send when the traffic channel is in use. Radios performed to induce or operate a wireless location detection system by using cryptography on the traffic channel for security and by using a temporary nickname (temporary mobile station identifier (TMSI)). The usefulness of network monitoring will be limited. A wireless device connected to such a GSM / GPRS / UMTS wireless network only periodically "listens" for transmissions to the wireless device, including call setup, voice / data processing, and Call disconnection (call) Do not send signals to a wide range of receivers except during breakdown). This reduces the probability of detecting wireless devices connected to the GSM network. In some cases, this shortcoming can be overcome by actively "testing and asking for a response" to all wireless devices in the area. However, this method puts a great deal of stress on the capacity of the wireless network. In addition, if the wireless device actively test-transmits and asks for a response, it can also warn the user of the mobile device of the use of the location detection system, and the effectiveness of applications based on polling location detection. May decrease, or its annoyance may increase.</p><p> U.S. Patent Application No. 11 / 198,996 cited above "Geo-Fencing in a Wireless Location" "system" describes the methods and systems employed by wireless location detection systems to detect the location of wireless devices operating in a defined geographic area, which the wireless communication system is responsible for. The system can define a geo-fenced area and then monitor the default signaling link set of the wireless communication system. The monitoring can also monitor the geo-fenced area as follows: It can also include detecting that the mobile device has performed any of the actions: (1) entering the geofence area, (2) leaving the geofence area, and (3) geofence. The area was approached within the specified proximity. In addition, this method determines the geographic location of the mobile device in response to detection that the mobile device has performed at least one of these actions. To do so, it can also include inducing precision position detection functions. The application uses the concept of geofence areas to calculate geographic locations and local, territorial, or national legal discretion. Described are methods and devices that enable, selectively enable, limit, reject, delay certain functions or services based on a preset location area defined by the invention, however. Is by no means limited to systems that employ the geofence technology described in US Patent Application No. 11 / 198,996 cited above.</p>

The above abstract and the following detailed description can be understood more deeply when read in connection with the accompanying drawings. For the purpose of exemplifying the present invention, the drawings show an exemplary structure of the present invention, but the present invention is not limited to the specific methods and means to be disclosed.
A. The big picture The Location Detection Device Platform (LDP) Client 110 and LDP Server 220 (see Figures 1 and 2, respectively) enable location detection services for both physical items. In one mode, the item is or comprises a wireless communication device (cell phone, PDA, etc.) configured for gambling purposes. Since bets are controlled by local or state regulations (in the United States), legal betting locations are usually casinos, riverboats, parimutuel tracks, or designated. Limited to closed areas such as off-site locations. The use of LPD capabilities makes it possible to place bets anywhere under the control of regulatory authorities.
The LDP client device 110 can be used for both purpose-built and general purpose computing platforms with wireless connectivity and betting functionality. LDP server 220, a location-aware server resident in the telecommunications network, performs location checks on wireless LDP client device 110 (similar to existing system checks for IP addresses or telephone area codes). And it can be determined whether or not the wager functionality can be enabled. The actual betting application can reside on the LDP server 220 or reside on another network connection server. The LDP server 220 can also supply a game permit index or geographical location to a human operator / contact.
The location detection methodology adopted by wireless location detection systems may depend on the service area deployed or requirements from the betting entity or regulator. Network-based location detection systems include POA, PDOA, TOA, TDOA, or AOA, or combinations thereof. Device-based position detection systems can include those using POA, PDOA, TOA, TDOA, GPS, or A-GPS. A hybrid of multiple network-based techniques, multiple device-based techniques, or a combination of network and device-based techniques can also be used to achieve service area or location-based service accuracy, yield, and latency requirements. Can be used. The location-aware LDP server 220 can determine the location detection technology to use from the available ones based on the cost of location capture.
The LDP client device 110 preferably includes a radio communication link (radio receivers and transmitters 100, 101) to communicate with the LDP server 220. Wireless data communications can include cellular (modems, CPDP, EVDO, GPRS, etc.) or wide area networks (WiFi, WiMAN / MAX, WiBro, ZigBee, etc.) associated with location detection systems. The wireless communication method can be independent of the functionality of the wireless location detection system. For example, the device can capture a local WiFi access point, but then seek a nearby location and use GSM to propagate the SSID of the WiFi beacon to the LDP server 220.
The LDP server 220 authenticates, authorizes, invoices, and controls the use of the LDP client device 110. Preferably, the LDP server 220 also maintains the service area rules and betting rules associated with each service area. The service area can be a polygon determined by a set of longitude / latitude points, or a radius from the center point. The service area can be defined within the location-aware server by interpreting the game status. Based on service area regulations, rules, and calculated locations, LDP Server 220 may or may not grant access to game services with full, limited access to wireless devices. The LDP server 220 also preferably supports a gambling application, in which case the LDP client device 110 enters or exits the service area. (And betting server) will be notified. The LDP server 220 preferably supports a large number of limited access instructions. Limited access to the betting service can mean that only simulated play is possible. Limited access to the service can also mean that real multiplayer games are possible, but wagers are not allowed. Limited access to the service can be determined by the time or place of the day combined with the time of the day. In addition, limited access to the service can also mean booking a game within a predetermined area at a particular time.
The LDP server 220 can issue a denial of service to both the LDP client device 110 and the betting server. The denial of service can also allow the presentation of guidance on where the requested game is permitted.
LDP client device 110 and LDP Server 220, card games, table-gate over-time, board games, horse racing, auto racing, athletic sports, online RPG, and online first person shooter (first person shooter ) Based on all online games and betting activities can be enabled.
It is also recalled that the LDP server 220 may be owned and managed by a wireless carrier, gaming organization, or local regulatory board, but it is not necessary.
This will give a brief overview of the two use cases.<u style="single">Use Case: Geo Offense</u>
In this context, the LDP client device 110 is a dedicated game model that uses GSM as a wireless link and network-based uplink TDOA as a location detection technique. Handed out when passengers arrive at the airport, the LDP client device 110 first supports game tutorials, advertising, and mock play. When the device enters the service area, it informs the user through audible and visual indicators that the device is now ready for real betting. This is an example of a geofence application. Billing and winning can be done through a credit card or can be charged / refunded to the hotel room number. When the LDP client device 110 leaves the area, audible and visual indicators indicate that the device is no longer able to make a real bet, and the LPD server 220 issues a denial message to the LDP client device and betting server. To do.
<u style="single">Use Case: Access Attempt</u> In this context, the LDP client device 110 is a general purpose mobile computer with a WiFi transmitter / receiver. The betting application client resides on your computer. Each time the betting function is accessed, the LDP client device 110 queries the LDP server 220 for permission. The LDP server 220 obtains the current location based on the WiFi SSID and reachable power, compares the location to the service area regulations, and grants or denies access to the selected betting application.

Includes FLT), Multilateration (EOTD), Observation Time Difference (O-TDOA), Global Positioning System (GPS), and Auxiliary GGPS (A-GPS). The location detection technique may also depend on the characteristics of the underlying radio communication or radio location detection system selected by the LDP or LDP server 220.
The location determination subsystem also allows the network-based receiver to sequence the most likely sequence by inserting the signal power, duration, bandwidth, and / or delectability of the device (eg, a known pattern into the transmit signal). It can also act to enhance location detection in network-based location detection systems by modifying the transmission characteristics of the LDP client device 110 to maximize detection).
<u style="single">Display 103</u> If you have a display subsystem for your LDP client device, you should make it unique to LDP and optimize it for the specific location detection application that your device enables. The display subsystem can also be an interface to the display subsystem of another device. Examples of LDP displays can include sound waves, contact, or visual indicators.

Optimize system performance and power consumption in addition to normal CPU duties such as allocation, process resource limits, virtual memory management parameters, and input / output (I / O) management. If the location detection service application is running locally to the LDP client device 110, the processing engine subsystem 107 can be scaled to provide sufficient CPU resources.
<u style="single">Volatile local memory 108</u> Volatile local memory subsystem 108 is under the control of processing engine subsystem 107 and allocates memory to various subsystems and LDP client resident location detection applications.
<u style="single">Non-volatile local recording storage 109</u> The LDP client device 110 can maintain the local storage of the transmitter location, receiver location, or satellite ephemeris in the non-volatile local recording storage 109, depending on the power reduction conditions. If the location detection service application is running locally to the LDP client, such as application specific data, as well as identification, encryption code, presentation choices, high score, previous location, pseudonym, companion list, and default settings. Application parameters can be stored in the non-volatile local recording storage subsystem. C. Location-aware application compatible server (LDP server) 220
The LDP server 220 (see Figure 2) provides an interface between the wireless LDP client device 110 and a networked location-based service application. The following sections describe the components of the exemplary embodiment shown in FIG. It should be noted that the various functions described are exemplary and preferably performed using computer hardware and software technology. That is, the LDP server is preferably interfaced using wireless communication technology and implemented as a programmed computer.
<u style="single">Wireless communication network interface 200</u> The LDP server 220 is a LDP client, but not limited to, by a data link running over a wireless communication network as either a modem signal using a system such as CDPD, GPRS, SMS / MMS, CDMA-EVDO, or Mobitex. -Connect to device 110. The Wireless Communication Network Interface (RCN1) subsystem acts and directs the selection of the correct (for a particular LDP) communication system for push operation (sending data to the LDP client 110).

LDP subscriber records can include ownership, password / encryption, account authorization, LDP client 110 capabilities, LDP creation, models, and manufacturers, access certificates, and routing information. If the LDP client device is a registered device under the wireless carrier's network, the LDP server 220 control subsystem provides all relevant parameters that enable LDP access on the wireless carrier's network. It is preferable to maintain.
<u style="single">Accounting subsystem 203</u> The LDP accounting subsystem 203 handles basic accounting functions, including maintaining access records, access times, and location-based applications that access the location of LDP clients, with individual LDP client devices and individual LBS services. It is possible to charge for each. It is also preferred that the accounting subsystem record and track the cost of each LDP access by wireless communication network providers and wireless location network providers. Costs may be recorded by access and location. The LDP server 220 can be configured by a rule-based system so that access charges are as low as possible through the preference of the network and location detection system.
<u style="single">Authentication subsystem 204</u> The main function of the authentication subsystem 204 is the real-time authentication factor required by the authentication and encryption process used in the LDP network for LDP access, data transmission and LBS-application access to the LDP server 220. It is to supply (factor). The purpose of the authentication process is to protect the LDP network by denying access to the LDP network by unauthorized LDP clients or location detection applications, and during transport through the wireless carrier's network and wireline network. Make sure to maintain confidentiality.
<u style="single">Authorization subsystem 205</u> The authorization subsystem 205 uses data from the control and authentication subsystems to enforce access control for both LDP client devices and location-based applications. Access control to be implemented is Internet Engineering Task Force (IETF) Request for Comment RFC-3693, It may be specified in "Geopriv Requirements," the Liberty Alliance's Identity Service Interface Specifications (ID-SIS) for Geo-location, and the Open Mobile Alliance (OMA). The authorization subsystem may also obtain location data for LDP clients before permitting or denying access to applications based on a particular service or location. Grants can also be based on calendars or clocks, depending on the services described in the LDP profile record residing in the control subsystem. The authorization system can also control connections to external billing systems and networks and deny connections to unauthorized or unauthenticated networks.
<u style="single">Non-volatile local recording storage 206</u> The non-volatile local recording storage of the LDP server 220 is primarily used by the control, accounting, and authentication subsystems to store LDP profile recording, encryption keys, WLS deployment, and wireless carrier information.
<u style="single">Processing engine 207</u> The processing engine subsystem 207 may be a general-purpose computer. The processing engine manages LDP server resources and routes data between subsystems.
<u style="single">Volatile local memory 208</u> The LDP server 220 has a volatile local memory store consisting of multiport memory so that the LDP server 220 can scale with a large number of redundant processors.
<u style="single">External billing network 209</u> Authorized external billing networks and billing intermediaries can access the LDP Accounting Subsystem Database through this subsystem. Recordings can also be sent periodically through a pre-arranged interface.
<u style="single">Interconnect to external data network 210</u> Interconnections to external data networks are designed to handle the conversion of LDP data streams to external LBS applications. This interconnection to an external data network is also a firewall that prevents unauthorized access, as described in the Internet Engineering Task Force (IETF) Request for Comment RFC-3694, "Threat Analysis of Geopriv Protocol". Interconnects to External Data Network Subsystems A large number of access points residing in 210 address redundancy and configuration changes in the event of a denial of service or loss of service event. Examples of interconnect protocols supported by LDP Server 220 include the Open Mobile Alliance (OMA), Mobile-Location-Protocol (MLP), and Parlay X Specification for web services; Part 9: Terminal Location as Open Service Access (OSA); Parlay X web services; Part 9: Terminal location (also standardized as 3GPP TS 29.199-09) is included.
<u style="single">External communication network 211</u>External communication network refers to both public and private networks used by LDP Server 220 to communicate with location-based applications that are not resident on LDP Server 220 or LDP Client Device 110. D. Gaming system / process
FIG. 3 shows a system according to an embodiment of the present invention. As shown, such a system comprises one or more LDP client devices 110, and an LDP server 220. The LDP client device 110 can typically be configured for the types of gaming applications regulated by state and governmental agencies. As discussed above, the LDP client device can be equipped with a conventional calculator (eg, PDA), mobile digital telephone, etc., or may be a special device dedicated to games. The LDP client device 110 has the ability to provide users with wireless access to Internet-based game application servers. Such access can be provided through a wireless communication network (cellular, WiFi, etc.) as shown. In this embodiment of the system, the game application server contains or is coupled to a database of game information, such as information describing the geographic areas where betting is allowed.
As shown in Figure 3, the LDP server 220 and the game application server are operably coupled by a communication link so that the two devices can communicate with each other. In this embodiment, the LDP server 220 is also operably coupled to a wireless location detection system. The wireless location detection system may be of any type as long as it determines the geographic location of the LPD client device 110, as discussed herein. It is not necessary to locate the LDP client device with the accuracy required for emergency (eg E911) services, but to the extent necessary to determine if the device is in an area where betting is allowed. In addition, these positions may be detected.
With reference to FIG. 4, in one embodiment of the present invention, the LDP server is provided with jurisdiction information and information provided by the wireless location detection system. The exact details of what information affects the LDP server depend on the exact details of what kind of services the LDP server provides.
As shown in Figure 4, the LDP client device accesses the wireless communication network and requests access to gaming services. This request is derived from the game application server, which then requests location information from the LDP server. The LDP server requires WLS to detect the location of the LDP client device, and WLS returns the location information to the LDP server. In this embodiment of the invention, the LDP server determines that the LDP client device is within a predetermined jurisdiction and then determines whether to provide a game / betting service (or this determination is: It can also be the responsibility of the game application server). This information is provided to the game application server, which notifies the LDP client device of the determined game status determination (ie, whether to provide the game service). E. Other embodiments
<u style="single">LDP power savings with selective boot mode</u> Wireless devices typically have three modes of operation, sleep, wake (listen), and transmit to save battery power. In the case of LDP client device 110, the fourth state, position detection is possible. In this state, the LDP client device 110 first enters the boot state. From the received data or external sensor input, the LDP client determines if activation of the location determination engine or transmission subsystem is required. If the received data or external sensor input indicates that location transmission is not required, the LDP client device 110 returns to sleep mode with minimal power outflow without powering either the location determination or transmission subsystem. If the received data or external sensor input indicates that the location needs to be transmitted only if the device location changes, the LDP client device 110 performs device-based location detection and sleep mode with minimal power outflow. Return to. If the received data or external sensor input indicates that the location needs to be transmitted, the LDP client device 110 performs device-based location determination, activates the transmitter, and of the current LDP client device 110. Send the location (and any other request data) and return to sleep mode with minimal power outflow. Alternatively, if the received data or external sensor input indicates that the location needs to be transmitted, the LDP client device 110 activates the transmitter and locates the signal by network means (optimized for location determination). It can also send (at this point, the LDP client device 110 can also send any other request data) and then return to sleep mode with minimal power outflow.
<u style="single">Invisible roaming for non-voice wireless LDP</u> For LDP clients using cellular data communications, it is possible to pre-prepare the LDP client to minimize its impact on existing cellular authentication, control, authorization, and accounting services. In this scene, a single LDP platform is distributed to each cellular base station footprint (cell site electronics). The single LDP client device 110 is then registered with the wireless carrier as usual. All other LDPs in the area will then be based on a single LDP ID (MIN / ESN / IMSI / TMSI) to limit the impact of the HLR on the LDP server 220 (authentication of itself, Will use SMS messages to communicate with (has control, authorization, and accounting services). The server uses the SMS payload to determine both the true individual information of the LDP and the triggering action, location, or attached sensor data.
<u style="single">SMS location exploration using known patterns loaded into LDP</u> With the deployed WWLS control channel location detection architecture and SMS messages with known patterns of up to 190 characters in the A-bis surveillance system, the LDP client device 110 enhances the location of SMS transmissions. be able to. Since the character is known, the encryption algorithm is known, bit patterns are generated, and a complete SMS message is ideal for signal processing to eliminate common channel interference and noise and increase the accuracy possible in location estimation. It becomes available for use as a reference.
<u style="single">Location data encryption for privacy, distribution, and non-rejection</u> It is possible to employ privacy, redistribution, and billing non-repudiation enforcement methods using an encryption key server based on the LDP server 220. In this method, the LDP server 220 encrypts the location record before delivering it to any external entity (master gateway). The gateway can also release the record and pass the protected record to another entity. Regardless of the entity to be released, the key must be requested by the key server of LDP server 220. The request for this key (for a particular message to send) is the "private" key "envelope". Envelope) is released, meaning that the location sequence number (a random number assigned by the LDP server 220 to identify the location record) is read by the entity. The LDP server 220 then distributes the "private" key and the subscriber's location under the same "secret" key. The "secret" key repeats the location sequence and allows the location record to be read. In this way, protecting the privacy of the subscriber, the gateway redistributes the location record without reading and recording the data, and the reception of the record by the final entity is not rejected.
<u style="single">Enhanced overlay network-based location detection with LDP data channels</u> To perform network-based location detection enhancements, the LDP client device 110 should receive broadcast capture data, register it on the system (if necessary), and request data services from the wireless network. Can be configured in. The data connection is led to the LDP server 220 by the data network. When connecting to the LDP server 220, the LDP client device 110 then has its ID (including MIN / ESN / TMSI / TruePosition, for example) and its channel information (channel, CC, etc., for example). Included), its neighbors (eg, mobile auxiliary handoff (MAHO) list (accommodating target network stations, target channels, target time offsets, power offsets, etc.), any cryptographic bits that the network has given to the LDP client device 110. Immediately send strings and semi-random but known patterns sent through existing data paths. This semi-random sequence is instructed to be stopped by either the internal counter / timer or the LDP server 220. Until then, it is retransmitted in the (n) second iteration cycle (the (n) second iteration can be matched to the availability of the MAHO list).
The LDP server 220 selects network receivers based on the received channels and receivers available in the Neighbor (MAHO) list (if any), or from the internal table of station locations. Network-based wireless location detection then performs location detection up to the accuracy threshold required by the required quality of service.
The LDP server 220 can update the LDP timer, ID, programming, or other characteristics using the dual data path E established with the LDP client device 110. The LDP server 220 can then direct the LDP client device 110 based on location, cell ID, mode, bandwidth, or RF protocol. The signaling, voice, and / or data encryption of the cellular system is irrelevant to this application. This is because the data can be delivered for use in the data path to WLS.
<u style="single">LDP location detection with network-based wireless location detection system only</u> If the LDP client device 110 is not equipped with a device-based location determination engine, its location in a non-network-based WLS environment can be reported to the LDP server 220 equipped with SMSC. At the top level, the LPD client device 110 can report the system ID (SID or PLMN) number or secret system ID (PSID), so the WLS has the LPD inside (or outside) the WLS-equipped system. Can be judged. A Neighbor (MAHO) list sent over a control channel as a series of SMS messages can give a rough location in a network of friendly carriers that are not yet equipped with WLS. Reserved SMS can allow WLS to reprogram any aspect of LDP. If the LDP client device 110 is in an area equipped with a network-based WLS, the LDP client device 110 can use the network-based WLS to provide a higher level of accuracy.
<u style="single">Automatic transmitter location detection by LDP using network database</u> If the LDP client device 110 is designed for multiple frequency, multiple mode operation, or if the LDP client device 110 is provided with a connection to an external receiver or sensor, then the LDP client device 110 is in position. It becomes a detection-compatible telemetry device. For certain applications, the LDP client device 110 uses a radio communication subsystem or an external receiver to locate the radio broadcast. The reception of such a broadcast is identified by the transmit bandwidth or the information available from the broadcast, causing the LDP client device 110 to establish a data connection to the LDP server 220 and perform device-based location detection, or LDP. Initiates location-enhanced transmission for use by server 220 or other network-based servers.
An example of this variant use of the LDP client device 110 is as a networked radar detector for automobiles or as a WiFi hotspot locator. In either case, the LDP server 220 records network information and location and distributes it to an external location-aware application.
<u style="single">Use of externally derived precision timing for communication scheduling</u> Battery life can be an important enabler for at least some applications of autonomous locating devices. In addition, the time and effort involved in periodically charging or replacing the battery in the location-specific device is expected to be a significant cost booster. The device is considered to have three states: active, idle, and sleep. Active = communicating with network Idle = state where you can enter the active state Sleep = low power state
Power consumption in the active state depends on the efficiency of digital and RF electronic circuits. Both of these technologies are considered to be mature and their power consumption is considered to have already been optimized. Power consumption in sleep mode depends on the amount of circuitry that is active during sleep. The fewer circuits there are, the less power is consumed. One way to minimize power consumption is to minimize the amount of time spent idle. During the idle state, the device must periodically listen to the network for commands (paging) and enter the active state when it receives it. In a standard mobile station (MS), to minimize the amount of time spent idle, limit the amount of time a paging command can be issued for any particular mobile station.
In this aspect of the invention, absolute external time reference (GPS, A-GPS, or information broadcast over a cellular network) is used to accurately calibrate the internal time reference of the location-specific client device. With an internal temperature sensing device, the device can temperature guarantee its own standards. The GPS or A-GPS receiver can be part of the location determination engine of the LDP client device 110 used for device-based location estimation.
Given that the location device has an accurate time reference, the network can schedule the device to enter idle mode at the correct time, thereby maximizing the amount of time spent in the lowest power state. Can be done. This method also minimizes the load on the communication network by minimizing the failure of communication attempts with devices in sleep mode.
<u style="single">Speed, time, altitude, area service</u> The functionality of the LDP client device can also be incorporated into other electronic devices. Therefore, using a location-aware device that wirelessly communicates with an external server that has a database of LDPs, service parameters and rules used, not only location within the service area, but also cell phones, PDAs, radar detectors, or the like. Services can be granted, restricted, or denied based on time, speed, and altitude for various electronic devices such as interactive systems. Since the time includes both the time of the day and the cycle of time, the duration of service can be limited.
<u style="single">Intelligent mobile proximity</u> Pairing the LDP client device 110 with another LDP client can provide an intelligent proximity service, and granting, limiting, or denying a service can be based on the proximity of the LDP pair. .. For example, for anti-theft use, the LDP client device 110 can be incorporated into a car, while another LDP can be incorporated into a car radio, navigation system, or the like. Create an anti-theft system by registering a pair of LDP clients with the LDP server 220 and setting inducing conditions for location determination based on activation or removal. If removed without permission, the LDP client device 110 inside the removed device either denies service or allows service while telling the location of the stolen device with the LPD client inside. F. Location detection techniques: network-based, device-based, and hybrid
Each wireless location detection system includes a transmitter and a receiver. The transmitter creates a target signal [s (t)], which the receiver collects and measures. The measurement of the target signal may be performed by either a wireless device or a network station. The transmitter or receiver can remain in operation during the signal measurement interval. If either (or both) movements can be accurately defined a priori, both can remain in motion. Network-based location detection technique
When measurements are made in a network (a geographically dispersed collection of one or more receivers or transmitters and receivers), the location detection system can be described as network-based. Network-based wireless location detection systems can use TOA, TDOA, AOA, POA, and PDOA measurements, and the final location calculation often includes two or more independent measurements. It becomes a mixture. The receiver or transmitter / receiver connected to the network is different, including base station (cellular), access point (wireless local access network), reader (RFID), master (Bluetooth) or sensor (UWB). Known by name.
In a network-based system, the signal to be measured originates from the mobile device, so the network-based system receives and measures the arrival time, arrival angle, or signal strength of the signal. Sources of location detection errors in network-based location detection systems include network station topology, signal path loss, signal multipath, common channel signal interference, and land terrain.
The network station topology may not be suitable for network-based location detection techniques because the sites are lined up in a row (along the road) or the sites have few neighbors.
The signal path loss can be compensated by increasing the transmission power used and lengthening the sampling period. In some wireless environments (wide area, multiple access spectrum spread systems such as IS-95CDMA and 3GPP UMTS), there is a problem with hearing capability due to the low allowed transmission power.
Multipath signals also affect shoji, position detection accuracy and yield of network-based systems due to additive and subtractive interference of reflection and non-line-of-sight signal paths, making dense urban environments a particular problem. Multipath can be compensated by using multiple separate receiving antennas for signal acquisition and post-collection processing of multiple received signals by removing time and frequency errors from the collected signals prior to location calculation. it can.
Common channel signal interference in a multiple access wireless environment can be achieved by monitoring device-specific features (eg, color code) or by digital common mode filtering and correlation between collected signal pairs to remove spurious signal components. It can be minimized.
<u style="single">Network-based-TOA</u> The network-based arrival time system relies on a target signal broadcast from the device and received by the network station. Variants of network-based TOA include those outlined below.
<u style="single">Single station TOA</u> The range measurement can be estimated from the round trip time of the polling signal passed between the transmitter and receiver and then returned. In fact, this distance measurement is based on the TOA of the return signal. By combining the distance estimates with the known locations of the network nodes, location estimates and error estimates are obtained. Signal station TOA is useful in hybrid systems where additional location information such as reach angle or reach power is available.
Commercial applications of the signal station TOA technique include the CGI + TA location detection method described in ETSI Technical Standards for GSM: 03.71, and Location Services (LCS); Functional description by the 3rd Generation Partnership Project (3GPP). Found in Stage 2_23.171.
<u style="single">Synchronous network TOA</u> Network-based TOA location detection in a synchronous network uses the absolute arrival time of radio broadcasts with a large number of receiver bonds. Since the signal travels at a known speed, the distance can be calculated from the arrival time at the receiver. The arrival time data collected at the two receivers narrows the position to two points, and TOA data from the receiver is required to clarify the exact position. The low accuracy in timing synchronization slips directly into the location estimation error. Other static error sources that can be eliminated without calibration include antenna and wiring latency in network receivers.
An example of a future synchronous network TOA that is possible when ultra-precision (atomic) clocks or GPS time standards become affordable and portable is a common time standard for transmitters and receivers. It will be for fixing to. If both the transmitter and the receiver have a common timing, the time-of-flight can be calculated directly and the distance can be determined from the flight time and the speed of light.
<u style="single">Asynchronous network TOA</u> Network-based TOA location detection in an asynchronous network uses the relative arrival time of the radio broadcast in the network-based receiver. In this technique, all differences in the distance between individual receiver bonds and the timing of individual receivers must be known. Then, for the receiver bond, the signal arrival time is normalized, leaving only the flight time between the device and each receiver. Since the radio signal travels at a known speed, the distance can be calculated from the normalized arrival time obtained at the receiver. The exact location will be elucidated using the arrival time data collected from three of the more receivers.
<u style="single">Network-based TDOA</u> Network-based (uplink) arrival time difference In a wireless position detection system, a large number of network receivers / transmitters / receivers collect, process, and time-stamp target transmission signals. The location of each network station, that is, the distance between stations, is known accurately. Time stamping at network receivers requires a very stable clock and a high degree of synchronization, or a known timing difference between receivers.
The measurement time difference between the collected signals from any pair of receiving stations can also be represented by a hyperbola of position. The position of the receiver can be determined somewhere on the hyperbola where the time difference between the received signals is constant. The location estimation can be determined by repeating the hyperbola determination of the position between each receiver pair and calculating the intersection between the hyperbolas.
<u style="single">Network-based AoA</u> The AOA method determines the location of a transmitter by using multiple antennas or multi-element antennas at two or more receiver sites and determining the angle of incidence of the reaching radio signal at each receiver site. With reference to US Pat. No. 4,728,959, "Direction Finding Localization," the AoA technique is ultra-wideband (UWB) or WiFi (as originally described as providing location detection in an outdoor cellular environment. IEEE802.11) It can also be used indoors using wireless technology.
<u style="single">Network-based POA</u> Reach power is a proximity measurement used between a single network node and a wireless device. If the system consists of a transmitter / receiver, both forward and reverse channels are available between the device and the network node, and the wireless device can be instructed to use some power for transmission. Otherwise, the power of the device's transmitter must be known a priori. Since the power of the radio signal decreases with distance (due to the attenuation of the radio wave by the atmosphere and the combined effect of free space loss, plane earth loss, and diffraction loss), the distance from the received signal The estimated value can be determined. In simplest terms, the longer the distance between the transmitter and the receiver, the more radiated radio energy is modeled as if it diffused over the surface of the sphere. This spherical model means that the radio power at the receiver decreases with the square of the distance. This simple POA model can be refined by the use of a further improved propagation model and the use of calibration by inspection transmission at the likely transmission site.
<u style="single">Network-based POA multipath</u> This reach power position detection technique uses features of the physical environment to detect the position of a wireless device. Radio transmission is reflected and absorbed by objects that are not in direct line of sight on the path to the receiver (either the network antenna or the antenna of the device), resulting in multipath interference. At the receiver, the sum of many time-delayed and attenuated copies of the transmission arrives collectively.
The POA multipath fingerprinting technique uses the amplitude of a multipath degradation signal to characterize the received signal and match it against a database of amplitude patterns known to be received from certain calibration locations.
To use the multipath fingerprint method, the operator calibrates the wireless network (using inspection transmissions performed in a grid pattern that spans the entire service area) and uses the amplitude pattern fingerprint for later comparison. Build a database. Periodic calibration is required to update the database and compensate for changes in the radio environment due to seasonal changes and the effects of construction or removal in the calibration area.
<u style="single">Network-based PDOA</u> The reached power difference requires a one-to-many arrangement, resulting in a large number of sensors and one transmitter, or a large number of transmitters and one sensor. The PDOA technique must be able to know the transmit power and sensor location a priori and calibrate the power readings at the measuring sensor for localized amplification or attenuation (relative to the antenna and sensor). ..
<u style="single">Network-based hybrid</u> Network-based systems can be deployed as mixed systems using network-based alone or a mixture of network-based and device-based location detection technologies. Device-based position detection technique
Device-based receivers or transmitters and receivers have different names: mobile stations (cellular), access points (wireless local access networks), transponders (RFID), slaves (Bluetooth), or tags (UWB). But it is known. In a device-based system, the signal to be measured is emitted in the network, so the device-based system receives the signal and measures its arrival time or signal strength. The calculation of the device location can be performed on the device, or the measured signal characteristics can be sent to the server for further processing.
<u style="single">Device-based TOA</u> Device-based TOA location detection in a synchronous system uses the absolute arrival times of multiple radio broadcasts in a mobile receiver. Since the signal travels at a known speed, the distance can be calculated from the arrival time at the receiver, or it can be transmitted back to the network and calculated at the server. The arrival time data from the two transmitters narrows the position to two points, and the data from the third transmitter is needed to determine the exact position. Network base station synchronization is important. The low accuracy in timing synchronization slips directly into the location estimation error. Other static error sources that can be eliminated without calibration include antenna and wiring latency in network transmitters.
A possible future synchronous network TOA implementation when ultra-precision (atomic) clocks or GPS time standards become affordable and portable is a common time standard for transmitters and receivers. It will be for fixing to. If both the transmitter and the receiver have a common timing, the time-of-flight can be calculated directly and the distance can be determined from the flight time and the speed of light.
<u style="single">Device-based TDOA</u> Device-based TDOA is based on signals collected by mobile devices from geographically dispersed network transmitters. If the transmitter does not provide its location (either directly or through broadcast), or if the transmitter location is not maintained in the device's memory, the device will not be able to perform TDOA location estimation directly and information about the collected signal. Must be uploaded to the land server.
A very stable clock and transmitter are in sync for the network transmitter to broadcast the signal, or the timing difference between the transmitters is located either wirelessly or on a land server. It is necessary for the judgment engine to know.
Commercial position detection systems using device-based TDOA include Altitude Forward Link Triangulation (AFLT) and Multilaterated Forward Link Triangulation (EFLT), both standardized in ANSI standard IS-801. These are used as medium accuracy fallback location methods in CDMA (ANSI standards IS-95, IS-2000) networks.
<u style="single">Device-based observation time difference</u> Device-based observation staggered position detection techniques measure the time it takes for signals from two or more network transmitters to reach three geographically scattered locations. These locations can be fixed locations within the wireless handset population or network. The location of the network transmitter must be a priori known to the server performing the location calculation. The position of the handset is determined by comparing the time difference between the two sets of timing measurements.
Examples of this technique include the GSM Multilateration Observation Time Difference (E-OTD) system (ETSI GSM Standard 03.71) and the UMTS Observation Time Difference (OTDOA) system. Combining both EOTD and OTDOA with network TOA or POA measurements can produce more accurate location estimates.
<u style="single">Device-based TDOA-GPS</u> The Global Positioning System (GPS) is a satellite-based TDOA system that allows receivers on Earth to calculate accurate location information. The system uses a total of 24 active satellites, with highly accurate atomic clocks located in six different but equally spaced orbital planes. The angular orbital plane has four satellites equidistant to maximize visibility from the Earth's surface. A typical GPS receiver user has between 5 and 8 satellites in the field of view at any given time. If you can see the four satellites, you will have enough timing information to be able to calculate the position on the earth.
Each GPS satellite transmits data containing information about its location and current time. Since all GPS satellites are synchronized in operation, these repetitive signals are transmitted at virtually the same time point. The signal travels at the speed of light and reaches the GPS receiver at a slightly different point in time. This is because some satellites are farther apart than others. The distance to a GPS satellite can be determined by calculating the time it takes for the signal from the satellite to reach the receiver. If the receiver can calculate the distance from at least four satellites, the position of the GPS receiver can be determined in three dimensions.
Satellites transmit a variety of information. Some of the main elements are known as ephemeris and ephemeris data. Astronomical data is information that enables accurate calculation of satellite orbits. Ephemeris data gives approximate positions for all satellites in the constellation, from which GPS receivers can discover which satellites are in the field of view.<maths num="1"><img file="JP2009522880A_D0001.tif" /></maths>here, i: number of satellites ai: Carrier amplitude Di: Satellite navigation data bit (data rate is 50Hz) CAi: C / A code (chipping rate is 1.023MHz) t: time ti0: C / A code initial phase fi: carrier frequency φi: carrier phase n: noise w: interference
<u style="single">Device-based hybrid TDOA-A-GPS</u> Taylor disclosed assisted GPS due to the long satellite capture time and low position detection yield when direct line of sight with GPS satellites was not available (US Pat. No. 4,445,118, "Navigation system and". method "(navigation system and method)). Wireless technology for position detection
<u style="single">Broadcast position detection system</u> A location detection system that uses a dedicated spectrum and is equipped with a geographically scattered receiver network and a wireless transmitter "tag" so that a system that supplies timing signals through a network of geographically scattered transmit beacons is possible. Can be used with the present invention, the LDP client device 110 functions as a receiving unit or a transmitting / receiving unit. The LDP client device 110 is well suited for both transmit tags and receive units in such wireless systems, depending on service area, accessibility, and location detection service pricing. Network can be used. When the location detection network operates in a dedicated spectral band, the LDP client device 110 can use its ability to utilize other wireless communication networks to talk to the LDP server 220 and the landside location detection application. Examples of these broadcast location detection systems are the Lo-jack vehicle recovery system, the LORAN system, and Rosum. Includes an E-OTD-like system based on an HDTV transmitter.
<u style="single">Cellular</u> All wireless (cellular) systems based on AMPS, TDMA, CDMA, GSM, GPRS, and UMTS support the data communication links required by the present invention. Cellular position detection systems and devices that enhance cellular position detection techniques are taught in detail in TruePosition's US patent. These patents cover a variety of position detection techniques and include, but are not limited to, AoA, AoA mixed, TDOA, TDOA mixed including TDOA / FDOA, A-GSP, mixed A-GPS. Many of the technologies described are now commercial services.
<u style="single">Local and wide area networks</u> All of these wireless systems are designed as purely digital data communication systems, not voice-centric, with additional data capabilities for secondary purposes. As a result of the interpollination of the various standards involved, there is considerable overlap in radio technology, signal processing techniques, and data stream formats. The Standards Institute (ETSI) Project for Broadband Radio Access Networks (BRAN), the Institute of Electrical and Electronics Engineers (IEEE), and Japan to harmonize the various systems developed. All of the Multimedia Mobile Access Communication Systems (MMAC) (Institute of Electrical and Electronics Engineers) (High Speed Radio Access Network Working Group) are active.
In general, WLAN systems that use unlicensed spectra will work without being able to hand off to other access points. Failure to coordinate between access points limits position detection techniques to single-station techniques, such as POA and TOA (round-trip delay).
<u style="single">IEEE 802.11-WiFi</u> WiFi is standardized as IEEE 802.11. Currently, variants include 802.11a, 802.11b, 802.11g and 802.11n. Designed as a short-range, wireless local area network with an unlicensed spectrum, WiFi systems are well suited for a variety of proximity detection techniques. Power is limited to comply with FCC Part 15 (Federal Regulations transmission rules, Part 15, Title 47 of subsection 245).
Part 15.245 of the FCC Regulation describes the maximum effective radiated power (EIRP) that can be transmitted by an unlicensed system and is allowed. This rule is intended for people under this department who seek to submit a system for a certificate. This is because the proven system has a transmit power of up to 1 watt (+36 dBm) towards the omnidirectional antenna and can have a gain of 6 dBi. As a result, EIRP is + 30dBm + 6dBi = + 36dBm (4 watts). If a higher gain omnidirectional antenna is found, the transmitted power to the antenna will be + 36 dBm for the system's EIRP. It must be reduced so that it does not exceed the EIRP. That is, for a 12 dBi omnidirectional antenna, the maximum power allowed is + 24 dBm (250 mW (+ 24 dBm + 12 dBi = 36 dBm). For a directional antenna used in a two-point system, EIRP increases by 3 dB in antenna gain. It can be increased by 1 dB each time. A 24 dBi dish antenna can provide + 24 dBm of transmit power to this high gain antenna, resulting in an EIRP of + 24 dBm + 24 dBi = 48 dBm (64 watts). Become.
The IEEE 802.11 proximity location detection method can be either network-based or device-based.
<u style="single">HiperLAN</u> HiperLAN is lacking in high performance wireless local area networks. HiperLAN is a collection of WLAN communication standards developed by the European Telecommunications Standards Institute (ETSI) and used primarily in European countries.
HiperLAN is a relatively short-range variant of broadband radio access networks designed to be a complementary access mechanism for private use as public UMTS (3GPP cellular) networks and wireless LAN type systems. HiperLAN provides high speed (up to 54Mb / s) wireless access to various digital packet networks.
<u style="single">IEEE802.16-WiMAN, WiMAX</u> IEEE802.16 is the number of an IEEE802 working group dedicated to one-point to multipoint broadband wireless access.
<u style="single">IEEE802.15.4-ZigBee</u> IEEE802.15.3 / ZigBee is intended to be a specification for low power networks for use such as wireless surveillance, optical control, security alerts, motion sensors, thermostats, and smoke detectors. 802.15.14 / ZigBee is built on the IEEE 802.15.4 standard, which defines the MAC and PHY layer specifications. "ZigBee" comes from the strengthening of the upper layers in development by a consortium of many vendors called the Zigbee Alliance. For example, 802.15.4 specifies 128-bit AES encryption, while ZigBee specifies how to handle cryptographic key exchanges. The 802.15.4 / ZigBee network is planned to operate on unlicensed frequencies, including the 2.4GHz band in the United States.
<u style="single">Ultra Wideband (UWB)</u> Part 15.503 of the FCC Regulation provides definitions and restrictions on UWB operation. Ultra-wideband is the latest embodiment of the oldest technique for modulating radio signals (Marconi spark gap transmitter). Use pulse code modulation to encode data on a broadband spectral spread signal.
Ultra-wideband systems transmit signals over a much wider frequency range than traditional wireless communication systems and are usually very difficult to detect. The amount of spectrum occupied by the UWB signal, i.e. the bandwidth of the UWB signal, is at least 25% of the center frequency. That is, in the case of a UWB signal centered on 2 GHz, the minimum bandwidth is 500 MHz, and the minimum bandwidth of a UWB signal centered on 4 GHz is 1 GHz. The most popular way to generate UWB signals is to send pulses with a duration of less than 1 nanosecond.
When transmitting binary information using very wideband signals, the UWB technique is also useful for position detection of either proximity (by POA) AoA, TDOA, or a hybrid of these techniques. Theoretically, the accuracy of the TDOA estimate is limited by several actual factors such as integration time, signal-to-noise ratio (SNR) with each received bond, and bandwidth of the transmitted signal. The Cramer-Rao bound exemplifies this dependency. This can be approximated as follows.<maths num="2"><img file="JP2009522880A_D0002.tif" /></maths>Where f<sub>rms</sub>Is the rms bandwidth of the signal, b is the noise etc. or bandwidth of the receiver, T is the integration time, and S is the smaller SNR of the two sites. The TDOA formula represents the lower boundary. In practice, the system deals with interference and multipath, both of which tend to limit the effective SNR. UWB radio technology is very resistant to the effects of multipath interference. This is because the signal bandwidth of the UWB signal is similar to the coherent bandwidth of the multipath channel, and different multipath components can be elucidated by the receiver.
A possible alternative to reach power in UWB is the use of signal bit rates. Since the signal-to-noise ratio (SNR) decreases with increasing power, after some point faster than the increase in power rating, the decrease in signal-to-noise ratio actually decreases from the increase in information throughput, Shannon capacity. It means the separation of, and therefore the reduction of throughput. Since the power of the UWB signal decreases with distance (due to the attenuation of radio waves by the atmosphere and the combined effect of free space loss, flat earth loss, and diffraction loss), the maximum possible bit rate increases as the distance increases. Decreases. Although limited in use for distance estimates, the bit rate (or bit error rate) can serve as an indicator of approach or distance to a wireless device.
In the simplest terms, radiated radio energy is modeled as if it diffuses over the surface of a sphere as the distance between the transmitter and receiver increases. This spherical model means that the radio power at the receiver decreases with the square of the distance. This simple model can be refined by the use of a further improved propagation model and the use of calibration by inspection transmission at the likely transmission site.
<u style="single">Bluetooth</u> Bluetooth was originally conceived as a wireless personal area network (W-PAN or simply PAN). The term PAN is used interchangeably with the official term "Bluetooth piconet". Bluetooth is designed for very low transmission power and can be used within 10 meters without a special directional antenna. With the use of high power Bluetooth devices or special directional antennas, it is possible even at distances up to 100 meters. Given the design philosophy behind Bluetooth (PAN and / or cable replacement), even a distance of 10m is suitable for the original purpose behind Bluetooth. Future versions of the Bluetooth specification may compete with IEEE 802.11 WiFi WLAN networks to enable even longer distances.
The use of Bluetooth for position detection purposes is limited to proximity (when the location of the Bluetooth master station is known), but if a directional antenna is used to increase distance or capacitance, the station's reach angle position Detection or AoA hybrids are possible.
As the slave device moves between piconets, the speed and direction of travel estimation can be obtained. Bluetooth piconets are designed to be dynamic and constantly changing, so devices that leave one master's range and enter another master's range will have a short time period (usually between 1 and 5 seconds). A new link can be established. As the slave device moves between at least two masters, a direction vector can be formed from a known position on the masters. If a link is created between three or more masters (series), device orientation and velocity estimates can be calculated.
The Bluetooth network can provide the data link required for the present invention. Data from the LDP client device 110 to the LDP server 220 can also be established on the W-LAN or cellular data network.
<u style="single">RFID</u> Radio frequency identification (RFID) is an automatic identification and proximity location detection method that is based on storing data using a device called an RFID tag or transponder and reading it from a distance. RFID tags are encapsulated wireless transmitters or transmitters and receivers. The RFID tag has a built-in antenna and receives and responds to radio frequency queries from RFID readers (radio transmitters and receivers), and then responds with a radio frequency response that includes the contents of the tag's solid-state memory.
Passive RFID tags do not require an internal power supply and are supplied by inductively coupling the reader to a coil antenna inside the tag or by backscattering coupling between the reader and the tag's dipole antenna. Use the power that is generated. Active RFID tags require a power source.
RFID wireless location detection is based on the reach power method. This is because the tag sends the target signal only when it is in close proximity to the RFID reader. Since the tag is active only when scanned by the reader, the location of the tagged item is determined from the reader's known location. RFID enables location-based services based on proximity (location detection and location detection time). RFID does not provide information on the speed or direction associated with the progression.
RFID readers, even equipped with sufficient wired or wireless backhaul, are unlikely to provide sufficient data link bandwidth for the present invention. In a more likely implementation, the RFID reader provides location instructions, while the data connection for the LDP-LDP server 220 can also be established over a WLAN or cellular data network.
<u style="single">Near field communication</u> A variant of passive RFID systems, Near Field Communication (NFC), operates in the RFID frequency range of 13.56 MHz. Proximity detection is possible and the NFC transmitter distance is less than 8 inches. NFC technology is standardized in ISO 18092, ISO 21481, ECMA (340, 352 and 356), and ETSI TS 102 190.
