A wireless access point (WAP) configured to supporting wireless communications with station nodes on a selected communication channel of an associated wireless local area network (WLAN). The WAP includes multiple multiple-input multiple-output (MIMO) transmit and receive paths. The WAP is to intermittently switch one of the multiple MIMO receive paths to concurrently process both communications on a selected communication channel together with monitoring communications on unselected channels of the multiple communication channels associated with the WLAN.

Channel tracking in a wireless home network

A wireless access point (WAP) configured to support a wireless home network among multiple wireless devices over a shared wireless communication medium on a selected channel. In an embodiment of the invention the WAP includes a channel tracker configured to track performance metrics over time for at least the selected channel; and to predict based on the tracked performance metrics at least one of: a predicted time of an impending channel changeover requirement in which a projected demand for the selected channel exceeds a projected capacity thereof and a predicted time of an impending monitoring interval for monitoring an unselected channel with relatively minimal disruption of communications on the selected channel. In another embodiment of the invention the WAP includes receive path components configured to concurrently process both communications on the selected channel together with monitored communications on an unselected channel.

A low complexity primary user detection system is disclosed. Signals are filtered to reduce the number of signals that must be processed. Width and PRI of the signals are used to match a constellation associated with a primary user. If the constellation is matched, communication parameters are adjusted to make way for the primary user.
