Wireless communication device

摘要

In a wireless communication device for performing plural wireless communications with different standards using the same frequency band, degradation of communication quality and communication speed due to communication interference is prevented, while drop in throughput and occurrence of frame loss are prevented. A first wireless communication section first performs wireless communication using a first frequency band and a second wireless communication section performs second wireless communication using a second frequency band with which at least a part of the first frequency band overlaps. The first wireless communication section analyzes a communication status signal which represents a signal pattern corresponding to communication status of the second wireless communication and then determines whether it is synchronous communication, and if it is, the first wireless communication section transmits/receives data in a non-communication period when communication in the synchronous communication is not performed, in synchronization with timing of the synchronous communication.

主权项

1. A method of wireless communication, comprising the steps of:
a) generating a communication status signal in a predetermined period of time which is set to a first value while a first wireless communication is operating and set to a second value while the first wireless communication is not operating in the predetermined period of time; b) analyzing the communication status signal; c) enabling a second wireless communication that is different from the first wireless communication when the communication status signal is not set to the first value in the predetermined period of time; d) suspending the second wireless communication when a total time of the communication status signal set to the first value reaches or exceeds a predetermined value in the predetermined period of time; e) when the communication status signal does not reach the predetermined value in the predetermined period of time and the communication status signal is cyclic, enabling a second wireless communication while the level of the communication status signal is the second value.
