Abstract: A wireless communications system and channel-switching method are disclosed herein. A source device and multiple sink devices independently maintain respective counters which track data packet errors. Each device independently switches channels only after its counter reaches a channel-switching threshold. The new channel switched-to is either determined by an indexed ordering of the available channels or by reference to a global clock maintained by each of the devices. Accordingly, all devices quickly arrive at a common channel. The system switches channels only when necessary and resolves quickly to a mutually acceptable channel. Therefore, unnecessary channel switching is minimized and data throughput is optimized.
