Abstract: The present invention provides a channel switching method for use with a wireless mouse by intelligently switching the communication channels with a wireless signal receiver. Firstly, the packet error rate is detected to discriminate whether the number of continuous failed packets is greater than a threshold value. Subsequently, the received signal strength indicator (RSSI) is detected to discriminate whether the wireless transmitter needs to switch the current communication channel with the wireless signal receiver.
