Abstract
A wireless access point (WAP) including: an airtime correlator, a dormancy allocator and a medium access control (MAC). The airtime correlator is configured to correlate airtime usage of the selected communication channel by the WAP with one of an idle WLAN state characterized by an absence of upstream or downstream communications and an active WLAN state characterized by at least one of upstream and downstream communications on the WLAN. The dormancy allocator is configured to allocate during at least one of the idle and the active WLAN states, a portion of available airtime to at least one dormancy interval in which a base power level of the WAP is reduced at least below a level required to support downstream communications. The MAC is configured to identify for the plurality of station nodes on the WLAN, a contention free period overlapping in time with the at least one dormancy interval.
