<u style="single">Field of application of the invention</u>The present invention relates to an improvement of an information transmission system, and more particularly to a system that needs to transmit data having a relatively wide bandwidth, such as compressed video data or real-time video data.<u style="single">Background technology</u>Electronic storage technology has reached the stage of whether a large amount of information can be stored relatively cheaply and can be accessed relatively quickly from a storage device. However, there is still a problem in transmitting a large amount of information on a communication channel or a communication network so quickly and conveniently that the customer can easily use it. Therefore, the present invention aims to address or essentially improve this problem.<u style="single">Outline of the invention</u>Therefore, in the uniform state of the present invention, an information transmission system for transmitting information from the first position to the second position is provided. The system transmits the information between the first information processing means provided at the first position, the second information processing means provided at the second position, and the first and second positions. It consists of a communication channel adapted to the information processing. The information may be stored in digital form in the first position or in analog form. This information may also be transmitted in digital form or in analog form through the communication channel. Preferably, the first position is the storage location and has a storage bank for storing the information, and the second position is the utilization location and has means such as information output, display, presentation or playback recording. A storage bank may also be provided at the second position. The communication channels may be put into production as bandwidth data paths, since there are multiple channels that work together to connect the first position to the second position, each with a predetermined bandwidth. , A bandwidth larger than any of the bandwidths of each channel can be used for information transmission. The communication channel can also form an apparently wide band channel by compressing information prior to transmission through the channel. The information is preferably transmitted in real time through the communication channel. This information may also be transmitted in compressed form in a shorter time than in real time. The first information processing means includes an information storage means and an information compression means, and the data is handed from the information storage means to the information compression means and compressed before being returned to the storage means. This information is preferably repeatedly compressed by repeatedly performing the compression means in an adaptive and selective manner. The second information processing means includes an information decompression means and a data storage means. It is preferable that the information is decompressed by the decompression means before it is stored in the storage means. In addition, this information should be adapted and selectively repeated by repeating the defrosting means. It is repeatedly decompressed by, which potentially means that there is a repetitive exchange between the decompression means and the storage means. In addition, the communication channel may have at least a portion of a cable, satellite, microwave or fiber optic of a PSTN, ISDN, or cellular telephone network. Preferably, the second information processing means includes various means such as presentation, playback recording, output, and display of voice, text, graphic, or video information, thereby from the data transmitted on the communication channel. Information can be provided to the user in the second position. Examples of this display means include a personal computer system, a television receiver, a videophone terminal, a handheld mobile phone having a built-in video data display, and the like. The mobile phone has a relatively high electromagnetic radiation emitting part and a relatively low electromagnetic radiation emitting part, and the lower radiation emitting part is installed on or near the user's head and is raised. The higher electromagnetic radiation emitting part is placed in a place other than the user's head, and is compatible with the communication with the cellular telephone network. The present invention also relates to a video compression technique, and more particularly to a method of effectively utilizing the above technique in a place where a large amount of video data is transferred. Therefore, in another aspect of the present invention, a system for transmitting video information from the storage location to the usage location is provided, and the system is provided in the storage location to store the video information in a digital format. It is provided with a storage bank and a video information reproduction / recording means provided at a place of use. The system further comprises transmission means to transmit the video information from the storage location to the usage location upon request. Here, a storage bank may be installed at the place of use. Preferably, the transmission is carried out through a communication medium consisting of either a public switched telephone network or unused or spare television channel bandwidth. The means of transmission should convey the video information. Further, according to another aspect of the present invention, there is provided an information transmitting system including a wide area signal transmitting means for transmitting a signal containing information to a plurality of local receiving means distributed over a wide area. .. Here, since each of the local receiving means transmits a signal to each local signal processing means, the signal is processed to be transmitted on the local cellular telephone network for reception at the cellular receiver. The information may be compressed by local receiving means and decompressed at each cellular receiver prior to transmission on the local cellular telephone network. In addition, this information may be passed to two or more channels of the local cellular telephone network as broadband information, in which case the information is transmitted in synchronization with a designated cellular receiver. .. Further, the present invention relates to communication for transmitting information having a relatively wide band width to a cellular telephone network or the like, and particularly to transmission of video information to the network. Therefore, a method of establishing a broadband data path on a cellular telephone network is provided. This wide bandwidth data path is wide enough for real-time video information to establish a videophone connection between subscribers on the cellular telephone network. The data path also comprises a plurality of individual channels, each comprising a bandwidth portion of a bandwidth data signal allocated across the plurality of individual channels. In yet another aspect of the invention, a wide bandwidth data path is provided on the cellular telephone network, in which each is limited to a predetermined bandwidth and together to connect subscribers. Multiple working channels can be established, thereby establishing a wide bandwidth data connection between subscribers with a bandwidth greater than any of the bandwidths of each channel. Furthermore, the present invention relates to a modular cellular telephone, in particular to minimize the radiation level emitted from a telephone near the user's head. It concerns cellular telephones that are suitable for stopping. Therefore, in yet another aspect of the present invention, a mobile telephone communication device having a high radiation output unit and a low radiation output unit is provided, in which the low radiation output unit is physically combined with the high radiation output unit. The high-radiation output unit wirelessly communicates with the base station of the mobile telephone network to which the mobile telephone communication device is connected, and also communicates with the low-radiation output unit at a predetermined low-radiation output. The low radiation output unit also communicates with the high radiation output unit at a low radiation output.<u style="single">[Simple explanation of drawings]</u>In order to facilitate the understanding of the present invention and to describe the actual effect, the following accompanying drawings are referred to.

Information transmission occurs across the communication medium 12 between both locations. The equipment of the storage location 10 includes a storage bank 13, a compression device 14, and a transmitter / receiver 15, all of which are mainly composed of a first information processing means controlled by the system controller 16. In this example, the storage bank stores the video movie in a digital format that is fully or partially compressed. Here, when a specific movie is selected, the digital information constituting the movie is handed over to the compressor if compression is required, and then the transmission / receiver uses the location 11 via the medium 12. It is transmitted to the device. Equipment located in the second location, or location 11, includes the corresponding receiver / transmitter 17, compression / decompression device 18, local digital storage device 19, credit card reader (or user verification device) 20, and video. It consists of a second information processing means including a reproduction controller / modulator 21. Since these devices are controlled by the system controller 22, the selected video movie is received from the digital storage bank 13, stored locally in the local digital storage device 19, and via the video playback controller / RF modulator 21. Can be played on a TV or display 23. The digital storage bank 13 can be composed of a high-capacity storage medium such as a WORM drive or a CD-ROM system having an ability to store information equivalent to many video movies. Further, the compressor 14 may be provided with a digital processor particularly suitable for compressing digital information prior to transmission, and the compressor / decompressor 18 can perform decompression prior to display. Transmitters / receivers 15 and 17 may each have a built-in modem, where the public switched telephone network is used as channel 12. In addition, T the transmission medium 12 using equivalent modulation / demodulation equipment. It can also consist of unused or spare bandwidth on the V channel. The system controllers 16 and 22 may be microprocessor-based controller devices suitable for controlling the transmission of information between the various components of the storage location and the usage location. Also, the local storage device 19 is a high capacity magnetic disk drive, while the video playback controller and RF modulator 21 receive video image input from the local store 19 as an alternative to the read head of the cartridge video player. It may be a modified video player suitable for. The credit card reader 20 may be any of the commercially available readers available on the market, and can be used as, for example, an EFTPOS terminal. When using it, the customer at the place of use 11 first starts browsing (snaps) and selects an operation via the system controller 22. The system controller 22 tells the digital storage bank 13 to supply appropriate summary information through the communication medium. In order to make a selection and initiate a send operation, a suitable credit or debit card (debit card) must be entered into the card reader 20 and the customer must pre-set a reasonable payment. If the payment signal is successful, the selected movie will be digitally sent from the storage bank 13 to the local store 19 via the communication medium 12 and the video of the video player 21. It can be accessed using a player control mechanism. These control mechanisms include mechanisms similar to those commonly found in cartridge tape video players. The storage system controller 16 can perform the following functions. (a) Accepting and processing user commands, and supplying messages in response. (b) Acceptance and processing of supervisor interactions, including the addition of functionality. (c) Continue to provide information such as invoices, income and expenditure reports, handling information, list information, etc. And to make available authority (security) information that assists in the operation of the system and its use at the place of use. (d) Control of data transfer between 13, 14, and 15. (e) Recovery from unauthorized commands, errors and unexpected disasters (power outages, etc.). (f) Compression work and data format management. (g) Data storage Layout, indexing, and search management. (h) Interface with other connectable related systems (computers, printers and other peripherals, intelligent image / video generators, receiving stations, etc.) for data and control interactions. In addition, the system controller 22 on the user side can perform the functions shown below. (a) Accepting and processing user commands, and supplying messages in response. (b) Providing information such as invoices, detailed reports from beginning to end, or handling, etc. upon request. (c) Make list and invoice information accessible to users from storage locations. (d) Enable data transfer or data control between 17, 18, 19 and 21, and user payment acceptance and authority input from 20. (e) Recovery from fraudulent commands, errors and unexpected disasters. (f) Management of compression / decompression work for local formats. (g) Management of local data storage and retrieval. (h) Interface with other connectable related systems for data and control interactions. (i) Providing fusion equipment for other systems that share the use of transmission line 12. (j) Use in the absence of transmission line 12 Appropriate operation of system components (ie, transfer tape etc. to local store 18,19, 21 etc.). Video compression technology allows users to use different bandwidths of transmission lines 12, different display characteristics and quality on TV / display 23, different storage modes, or local stores 19 or banks / data sources 13 for different applications. Can meet the changing needs of. This video compression technique consists of various compression methods, each of which is distinct, one of which is selected before use, or some are appropriately mixed during use. Since the methods shown below are selectively used and a continuous record of the selection method can be obtained, the recording of the selection method is also included in the compression / decompression device along with the compression data so that similar selections can be reproduced during compression / decompression. Is told to. Obvious conditions for switching selection methods are built into the compression / decompression algorithm, and those conditions are the same as the criteria used by the compression algorithm (ie, based only on the data already processed by that algorithm). If so, some of the above selection methods can be estimated. A variety of compression methods are available, including scene composition analysis, subsampling / quantization, compression standards and information theory coding. In the context of this description, "pixel" means an image information sample (ie, a point) that can be displayed digitally alone, and "frame" means a digital image that is completed as a single unit in a series of video scenes. "Scene" means a series of neighboring frames containing closely related data, "area" means a set of adjacent pixels within a frame containing closely related information, and "boundary" means each "Block" means a group of adjacent rectangles of pixels, and "line" means the individual pixel width of a block, meaning a set of adjacent pixels that are adjacent to other pixels in two or more areas. , "Texture" means a pattern relationship that exists between groups of adjacent pixels and is either regular or irregular, and "neighborhood" is a set of neighboring pixels for a particular single pixel. Means. With the scene composition analysis, A series of frames of video scenes are analyzed in digital format using a computer algorithm to confirm that: (i) Scene changes based on being above a given error tolerance between pixel values in adjacent frames. (ii) Movements and changes that affect size, position, orientation, detail (contour sharpness), clarity, color / brightness, texture, and the sharpness of the boundaries of the neighboring frame pair or the area covering the neighboring frameset. (iii) Mutual interaction of areas including overlap, transparency, distortion, overlay, etc. Next, the area is identified by the luminance / color and texture division method. Also, with subsampling / quantization, the reduction in the amount of pixel information per region or frame is initiated by all of the following, or from some of them. (i) Regular or non-regular (similar) or variable (irregular) I / O sample size and sample value set between regions, frames, or scenes. Spatial resolution reduction for subsampling or resampling pixel groups at blocks, lines, boundaries, and regions at regular locations or within half-frame alternating scout interlaces. (ii) Subsampling or resampling color / brightness and textures, defining representative subsets of them, modeling region changes and their importance, swapping pixel x pixel value specifications, fast The appearance of multiple regions with different distributions for motion (blurring, etc.), regular and repetitive motion (cycle of motion and kinephantoms), and visual understanding of the scene (blurring, random noise, etc.) Relative brightness / color perceived sensuously rather than directly measured and expressed), the visual degradation caused by increasing the visual effects associated with them. (iii) Frame subsampling or resampling is performed in succession, and pixels x pics on the separation over several frames Tempo resolution made by describing cell, region x region, and frame x frame changes at a good tempo and performing quantization on the types and amounts of changes that can be represented as described in (ii). Reduction. (iv) Any pixel group, such as blocks, regions, frames and scenes, accepts Fourier transforms and their associated transforms, subband decomposition, subband coding or signatures that allow a frequency band selected from the data, etc. Reduction of frequency resolution obtained by converting to an alternative representation that provides a frequency description of. The quantization techniques used include table indexing, vector quantization, stochastic clustering, decimation (1/10 removal), iteration improvement and selection, and the like. For compression standards, the formats established by existing ISO and CCITT standards are used (to facilitate production, utilize hardware production, compatibility between different compression and decompression equipment, etc.). These formats are considered to include: That is, (i) JPEG (ii) MPEG, MPEG-2, MPEG-4 (iii) H. 3 and 4 (v) JBIG Next, with information logic coding, the methods related to the above techniques are used to achieve an optimal and compact representation of compressed data streams or preprocessed data. A compressed data stream is generated. These methods include (i) entropy (probability) coding, (ii) codebook or dictionary construction, (iii) difference coding (missing or error), (iv) predictive coding, (v) context, Alternatively, coding based on the concept of neighborhood is included. In addition to the above methods, it is necessary to identify information for transmission to the decoder that describes which selection was made and which variable parameters are relevant to that selection. This is done by limiting a set of symbols to represent the differences in selection and inserting them into a system prior to or separate from the compressed data stream. These symbols may be further compressed by the methods described above. The decoder first decodes the compressed data stream and the selected symbols to provide an initial reconstructed version of the frame, then modifies or guesses the missing or approximate values and is needed for playback and display. Reconstructs pixels, areas, frames and scenes by achieving a high total resolution, systematic or random dithering, contour blurring, contour sharpening, or visual anthropogenic products. Includes resampling to hide. Although the present invention relating to the first embodiment has been described in a somewhat limited manner regarding the transmission of video information from the conceptual storage location to the conceptual usage location, the operation of the entire system described so far is broad. And it is intended to be viewed from a functional point of view. So, for example, the transmission medium 12 can be realized using analog or digital technology to form part of a public, dedicated, or corporate network. Further, for example, the transmission medium 12 can be realized by any of the following means. ISDN / B-ISDN line, including ADSL Excess channel space in an ist pair, or other PSTN medium, fiber optic, or other telecom data service infrastructure line, trunked radio, single or multiple channel cellular network, microwave line, satellite line, or TV broadcast spectrum. In some practical applications, the transmission medium 12 can also support bidirectional communication. Perhaps the most desirable use of interactivity is a mirror in which an image is formed overlaid on the system itself in Figure 1 so that each location has both memory and utilization capabilities. It would be such a case. Such a case will be described later in the following embodiment in the context of a personal communication device that communicates through a mobile telephone network or the like. If the lens is used in the desired form, bidirectionality of the transmission medium 12 can be achieved by exchanging commands, confirmations, data and video information where necessary and appropriate. The storage bank 13 can be put into practical use by using either digital means or analog means. The analog format of storage includes video discs, video tapes, and the like. It also includes a state in which the information moving from the storage bank 13 to the transmission medium 12 is generated in real time, for example, using information generated by a third party as a clue. When the information sent to the transmission medium 12 is extracted from one or more of the above information sources at the place of use 11 according to the user's request, composite equipment or jukebox equipment may be considered. The data stored in the storage bank 13 can be compressed in whole or in part. Furthermore, following the interactive compression procedure, data is sent from the storage bank 13 to the compression device 14 and returned to the storage bank 13 in a compressed format. The data compressed in this way may be sent to the compression device 14 again, further compressed, and returned to the storage bank. Similar work may occur during the compression and decompression work at 18 and 19. Furthermore, the data display or storage format is changed from broadcast format to analog format and from broadcast format to digit. The compression format may change from the tall format, the digital format to the digital format, and from the analog format to the digital format while the compression operation is repeated. In one embodiment of the present invention, the degree of compression, the nature of compression, the number of repetitions of compression, and the method of storing compressed data are determined in consideration of the characteristics peculiar to the transmission medium 12, and are requested by the user at the place of use 11. Follow the nature. The transmission medium 12 can carry information in various formats, from uncompressed real-time video data to compressed data, from real-time data to packets, or exchanged data, into a data bidirectional control flow. As mentioned with respect to the compression technique, the choice of information transmission properties on the transmission medium 12 also depends on the properties of the transmission medium 12 (but not limited to, in particular the bandwidth of the transmission medium and its transmission medium). It depends on whether it is bidirectional or not), and it also depends on the user's expectations and requests at the place of use 11. Therefore, since the system is given a certain degree of flexibility, different combinations of compression procedures and transmission media can be selected, and different performance / control requirements and timing characteristics for different applications can be satisfied. In the particular application described with respect to FIG. 1, the video information must be carried over the transmission medium 12 in a shorter time than the video information is displayed or played at the place of use 11 at normal video rates. The compression / decompression can also be selected at the usage location 11. For example, the compression / decompression device 18 may only partially decompress the data arriving on the transmission medium 12, thereby causing the local store 19 to partially decompress, partially decompress data, and partially decompress data. It can contain uncompressed data. Furthermore, the decompression procedure may be repeated, thereby removing the compressed or partially decompressed data from the local store 19 for the next decompression performed by the decompression device 18. To. This procedure takes place in real time or later. Local store 1 especially where iterative decompression should be used Since 9 is suitable for storing two or more data entities, the other data entity can undergo iterative decompression while one data entity is being processed by the playback controller 21. Furthermore, the video playback controller 21 can also undertake a final decompression of a narrow range of data in real time during playback. The playback controller 21 may include capture means, copy means, or other means such as video information storage means (video tape, video disc, CD, etc.). Line 24 also uses a linear RF fictitious connection to a standard TV set, but other alternative connection technologies should be used, especially where visual display should be performed by something other than TV23. Is also possible. For example, it is possible to output a display via a computer terminal screen, a display panel, a projector, a videophone, a multimedia terminal, a telephone conference station, an HDTV device, a cellular mobile video telephone, or the like. In this specification, the practical application of a mobile telephone will be described later. Further, the reproduction controller 21 can also incorporate equipment for the user to control the reproduction process either via local control or via a command issued through the system controller 22. General controls are done in the same way as a normal VCR, fast play, fast forward, fast reverse play, fast rewind, frame selection or play time setting, skip back and forth, frame freeze, split screen multiplex video display, Includes simultaneous multiple frame display reduction, multiple video displays and TV broadcast insertion or duplication. The equipment provided by the card reader 20 can also be put into practical use by other means. For example, payment request information can be input from the identification information built in the place of use, or the user can type in with a key on the keypad linked to the system controller 22. For certain purposes, for example, when the entire system is owned and operated by an entity. Creation of payment invoice information can also be omitted. If a similar system balance report is required along with the billing, at least in some productions, the management / registration information and access / authorization information must be sent along the communication medium 12 in either direction, so the system Controllers 16 and 22 can further communicate and collaborate with external networks and databases as needed to control the availability of system equipment and their balance reports. System controllers 16 and 22 have user interfaces 25 and 26, respectively. If the system controller 16 or 22 forms part of a computer system, a computer screen and keyboard for that system may be provided in the user interface 25 or 26. Alternatively, other types of interfaces such as keypads, touchpads and screens, mice, or LED or LCD displays are also available. To ensure flexibility in system usage, the system can handle video data in more than one format, as well as convert between formats such as PAL, NTSC, videophone, conference call systems, multimedia and HDTV. It is possible. To aid this, the system is able to negotiate its own internal video data format in preparation for internal transmission between the components of the system. As a result, the data arriving in any of the above individual formats is converted to the standard internal format when it is first entered into the system. This conversion is initiated within the system controller 16, but may be performed in either hardware or software. Alternatively, this conversion process may be attributed to storage bank 13 and transmit / receiver 15. The data processed and transmitted according to various embodiments of the present invention is assumed to be data for a video display, but other data. Data that accepts the purpose and other output formats will of course be obtained by the system. However, in general, the other data (for example, control data, voice data, etc.) are transmitted in a relatively small proportion of all the data transmitted per unit time. Further implementation and examples of the present invention will be described. In those examples, after the communication medium 12, at least to some extent, it is put into practical use by a cellular mobile telephone transmission system. Also, in these examples, the TV23 is replaced by a handheld or other videophone type device. Many commercializations of videophones can think of videophones as a superposition of storage and usage devices, as mentioned with respect to Figure 1. In these productions, most of the video data is generated in real time at one videophone position, transmitted to the other videophone position and immediately accepted (and "played and recorded"), so it is stored and stored. Little emphasis is placed on regenerative ability. Next, Figure 2 shows a system suitable for sending pay-TV signals, where both satellite and cellular telephone networks are used as part of the transmission path. The satellite considers a geographically large service area (for example, one country), while the cellular telephone network also has its control to provide localized information transmission. In FIG. 2, the broadband information transmission system 210 is arranged to deliver pay-TV services to the local subscriber's television set 211. In this specific facility, satellite 211, which is arranged to cover a geographically wide footprint (the range on the ground where satellites can send signals) (Australia, etc. as shown in the upper pointing diagram), is digitally arranged by means not shown. A compressed signal is supplied to. The satellite then retransmits the digitally compressed signal to the ground-based satellite bowl-shaped antenna 213. In principle, for each STD phone area, or One satellite antenna 213 is assigned to a similar collection of laser devices. The satellite antenna 213 sends the digitally compressed signal to the control / editing room 214 (which modifies the digitally compressed signal to suit the purpose of sending pay-TV services). The edited signal is then sent from the control room 214 to the public switched telephone network 215, where the signal is forwarded to the digital cellular mobile telephone network 216 and received by the designated cellular receiver 217. Digital cellular telephone networks are of the type such as GSM, CDMA or TDMA. Broadcast program information on this telephone network is either in a compressed or decompressed format, and is either on a single channel or on multiple channels of up to 16 channels. The cellular receiver 217 is suitable for receiving pay television signals transmitted over the digital cellular telephone network 216, decoding and expanding that information to the proper form. The resulting data is then converted to RF and received directly at the antenna input of the TV set 211. In addition, since the cellular receiver 217 includes a controller, the TV viewer can select the TV channel to watch and is required to pay for the received video information. In one embodiment, smart card or debit card accounting is performed by the cellular receiver 217 as a payment request for the received information. In addition, the cellular receiver 217 can be identified by its electronic serial number means using the currently standard cellular networks for identification. This arrangement allows both billing and identity assurance information to be recorded inside the cellular receiver 217 and sent back to control room 214 at the appropriate time. Figure 3 shows the typical equipment of a mobile cellular system (analog or digital), consisting of a relatively large number of cells. Inside these cells, mobile telephone offices keep in touch with each other Can be done. Cells are transmit and receive locations, usually distributed in networks between locations 5 km to hundreds of meters apart, depending on the expected congestion density of phone calls. A general telephone connection between the first mobile station 311 and the second mobile station 312 is established via the local transmitter / receiver base stations 313 and 314. These base stations 313 and 314 are in a relationship of directly communicating with the first and second mobile stations 311 and 312, respectively. Similarly, these base stations 313 and 314 are in a relationship of communicating with a main station such as the main station 315 or 316 by either a ground line or a wireless / microwave line. These main stations 315 and 316 can similarly communicate with the public exchange network (usually ground-based) (not shown). Next, FIG. 4 shows a communication path between the first mobile station 311 and the second mobile station 312. The line or individual channel 317 can be conceptualized as a data path established between mobile stations 311 and 312 having a predetermined bandwidth B. The small portion of the bandwidth B is received as the control layer 318, but most of the bandwidth is received by the user for user communication and is referred to as the signal layer 319. Data compression techniques selected and modified from those described above can be used to optimize and maximize the available bandwidth B. Figure 5 shows one way to increase the bandwidth available between two mobile stations in a cellular telephone network. Here, two video telephones 320 and 321 are simultaneously connected by means of four individual channels 317A, 317B, 317C and 317D for wideband data communication. For this facility, the effective bandwidth available for data transmission between the two videophones 320 and 321 is about four times that of B. In this case, the simultaneous establishment of four individual channels 317 interconnected to act as a single data path would be separate channels 317A, 317B, 317, respectively. It is controlled via the signal layer 319 of C and 317D. Next, regarding FIG. 6, the mobile telephone communication device 410 is composed of a high-radiation output cellular telephone module 411, which is physically separated from and distinguished from the low-radiation output handpiece (slave unit) module 412. It is a thing. The telephone module 411 incorporates standard electronic technology for mobile phones and includes a receiver / transmitter portion for communication with base station 413 at high output signal 414. The telephone module 411 also includes a second low power receiver / transmitter adapted for communication with the handset module 412 at the low power signal 415. The handset module 412 has a corresponding low power transmitter / receiver and is suitable for low range cordless communication. For this cordless communication between the handset module 412 and the telephone module 411, you can choose from one of 40 channels in either the 800-900MHz range or the 30-46MHz range. The handset module is equipped with a standard mobile phone keypad 416 and a digital display 417. The signal radiated from this slave module 412 is in the range of 1mW to 4mW. At the time of use, as shown in FIG. 7, the user 418 attaches the telephone module 411 to a belt or the like, so that the telephone module 411 has a relatively high output from the telephone module 411 to the base station 413 even if it is not on the head 419 of the user 418. Transmission is maintained. The handset module 412, which communicates with the telephone module 411 at low output, is used near the head 419 of the user 418 or pressed against the head (ear), and there is a risk of being exposed to harmful electromagnetic radiation. Can be reduced. The mobile phone 410 can be operated as any type of cellular telephone such as analog type, GSM type, CDMA type, TDMA type, or digital type. The modular equipment of this mobile phone 410 can also incorporate additional characteristics such as smart cards, pagers, diary and computer functions into either the phone module 411 or the handset module 412. It is controlled via the signal layer 319 of the 317D. Next, regarding FIG. 6, the mobile telephone communication device 410 is composed of a high-radiation output cellular telephone module 411, which is physically separated from and distinguished from the low-radiation output handpiece (slave unit) module 412. It is a thing.
