Patent attributes
A multi-radio wireless device capable of communicating on several wireless communication protocols (WCP) such as Wi-Fi, Bluetooth, ZigBee, etc. may select a communication channel for a desired WCPs by measuring both overlapping and non-overlapping channels of another WCP and determining combined congestion metrics (which measure communications of other devices using the particular channels) for those overlapping and non-overlapping channels. Each channel of the desired WCP may be measured using different combined congestion metrics as well as the individual congestion metrics for the potential channels of the desired WCP. The availability of particular channels of the desired WCP may be measured in this way to select a channel of the desired WCP that is most likely to be available and whose potentially interfering traffic (as measured by the congestion metrics) is least likely to interfere with other communications of a device, including other communications on other WCPs.
