Multiple wireless communication protocol methods and apparatuses including proactive reduction of interference

(57) Each 1st device mutually connected by network by wireless using the 1st wireless protocol which is a summary frequency hopping protocol, It is operated in cooperation by the aggregate of the device connected by network by wireless containing each 2nd device mutually connected by network by wireless using the 2nd wireless protocol including preventive reduction of interference between each above-mentioned network device. In one case of the operation, each 1st device of the above contains at least the 1st and 2nd subsets that operate by the 1st and 2nd frequency hopping pattern, respectively. The above-mentioned preventive reduction action operates by the way each 2nd device of the above supplements with the above-mentioned synchronous operation of each 1st device of the above, including synchronous operation of the 1st and 2nd subsets of the above of each 1st device of the above. In one case of the operation, the aggregate of the device connected by network by the above-mentioned wireless contains one wireless device at least which operates in both of wireless networks according to both of wireless protocols. This multiplex protocol device at least, Chance of being related with whether being carried out by the device of the 1st wireless network of the above, and transmission of the long packet covering the frequency of the plurality of the continuous frequency causing interference with the device of the 2nd wireless network of the above foreknowledge can be promoted.
