Wireless network equipment and public multi-channel MAC hopping method

It discloses an apparatus and a wireless network according to the present invention, a common medium access control method of multi-channel hopping. The wireless network device in a plurality of other nodes on a common channel with a wireless network according to the common frequency hopping sequence for communication, and comprising: a current channel detection means for detecting the device current channel is idle; time remaining the maximum determination means for the current channel is idle, it is determined whether the current time point to the time remaining in the time hopping sequence common channel switching time point is longer than the request message from the device to the desired destination node transmission time; communication means for transmitting the request message according to the determination result. The apparatus and method of the present invention can improve the success rate of RTS / CTS handshake, reduce the case since the destination node and the source node stays in different channels and cause data to be discarded.
