Sub-1ghz group power save

Abstract

Methods and systems are disclosed for reduced power consumption in communication networks, including sensor networks implemented according to IEEE 802.11ah, by organizing stations into groups having long sleep periods. By organizing the stations of the network into groups, the access point can match each group's traffic identification map with its target beacon transmit time. One embodiment organizes the stations sequentially by AID numbers. Other embodiments organize the stations by similar power save requirements and/or nearby geographical location. Forms of an Extended Traffic Identification Map are matched with an awaken Target Beacon Transmit Time of the group.

Dependencies are inferred from the claim text.
