METHODS AND APPARATUS TO MANAGE POWER CONSUMPTION IN WIRELESS LOCAL AREA NETWORK DEVICES
First Claim
1. A method comprising:
- performing a first received signal strength indicator (RSSI) scan to determine a beacon interval and a first beacon time for a wireless channel;
calculating a second beacon time for the wireless channel based on the beacon interval and the first beacon time; and
performing a second RSSI scan for the wireless channel during a time interval that includes the calculated second beacon time.

Abstract
Methods and apparatus to manage power consumption in wireless devices are disclosed. A disclosed example apparatus comprises performing a first received signal strength indicator (RSSI) scan to determine a beacon interval and a first beacon time for a wireless channel, calculating a second beacon time for the wireless channel based on the beacon interval and the first beacon time, and performing a second RSSI scan for the wireless channel during a time interval that includes the calculated second beacon time. In some examples, the wireless channel is a wireless channel that was previously identified as active, is a wireless channel that previously had the highest received power level, and/or is selected from a list of popular or frequently used channels. Additionally or alternatively, when a wireless channel with sufficient signal level is identified, scanning for additional channels is not performed.

12. An apparatus comprising:
-
a wireless receiver to perform received signal strength indicator (RSSI) scans; a receiver controller to enable the wireless receiver during a first time interval to perform a first RSSI scan for a wireless channel to determine a beacon interval and a first beacon time for the wireless channel, and to enable the wireless receiver during a second time interval that includes a calculated second beacon time to perform a second RSSI scan for the wireless channel to determine an RSSI value associated with the wireless channel; and a beacon time calculator to calculate the second beacon time based on the first beacon time and the beacon interval. - View Dependent Claims (13, 14, 15, 16)
