发明名称 System and method for enabling low power devices
摘要 Various embodiments are directed to a wireless access point capable of reserving a wireless communication channel by sending a quiet message to multiple legacy devices. The quiet message may include data identifying periodic quiet durations during which the legacy devices cannot access the wireless communication channel. The wireless access point may send a polling schedule to the multiple low power wireless devices. The polling schedule may include data identifying the periodic quiet durations. The wireless access point may then poll the multiple low power wireless devices during the periodic quiet durations. The low power wireless devices can exchange data with the wireless access point during the quiet durations. The quiet message sent to the legacy devices guarantees that the legacy devices will not use the specified channel during the quiet durations. Thus, communications with the low power wireless devices may occur without interference from the legacy devices.

主权项 1. An apparatus comprising: a wireless access point having a controller operative to:send a quiet message over a first Physical Layer (PHY) to one or more legacy devices to reserve a wireless communication channel, the quiet message including data identifying periodic quiet durations during which the legacy devices cannot access the wireless communication channel; send a polling schedule using a second PHY to one or more low power wireless devices, the polling schedule including data identifying the periodic quiet durations; and poll the one or more low power wireless devices during the periodic quiet durations using the second PHY.
