METHOD FOR WIRELESS ENERGY OPTIMIZATION

摘要

A method of optimizing the wireless power and signal integrity between an access point and multiple wireless clients includes an algorithm running in the access point that detects the downlink bandwidth and signal strength to a client device. Using this information, the wireless parameters of the access point can be adjusted to reach an optimal downlink power and signal condition. Uplink bandwidth and signal strength control to the access point is performed at each of the client devices using signal strength information provided by the access point. This achieves a dynamic balance with the adjustment of both the access point and the individual wireless client devices for transmit power control and signal integrity in a closed loop manner. The access point can perform the same dynamic balance while supporting multiple client devices operating in multiple frequency bands.

1. A method to provide closed loop control of wireless energy transmitted in a wireless local area network having an access point and multiple client devices, the method comprising:
measuring, by the access point, downlink bitrates from the access point to each of the multiple client devices in a frequency band of operation, and selecting a client device having a lowest downlink bitrate from among the multiple client devices; adjusting the access point transmitter power signal level, whereby the downlink bitrate of the selected client device is initially established using a minimum of access point transmitter power signal level; sending, by the access point to the multiple client devices, respective uplink signal reception levels measured at the access point, thereby allowing each of the multiple client devices to adjust an uplink transmitter power level based on the respective uplink signal reception levels measured at the access point; requesting, by the access point, a downlink signal reception level from the selected client device; minimizing the access point transmitter power level to the multiplicity of client devices based on the downlink signal reception level measured at the selected client device while maintaining the downlink bitrate of the selected client device; wherein minimizing the access point transmitter power level and allowing each of the multiplicity of client devices to adjust uplink transmitter power level provides closed loop control of the wireless energy transmitted in the wireless area network in the frequency band of operation.
