Abstract: 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.
