Patent ID: 8873457

Claim:
A method of configuring the operation of a wireless local area network (WLAN) device which is used in the transmission and reception of a service over a medium, the WLAN device comprising a WLAN chip set and power amplifier, the method comprising the steps of: determining, based on a measurement of network performance, a value of a WLAN traffic indicator metric used in the chip set at a specific time to estimate the WLAN traffic, the WLAN traffic indicator indicating an amount of WLAN traffic; predicting an estimation of the available bandwidth of the WLAN from the value of the metric; calculating a data rate of the WLAN based on estimated available bandwidth, a target packet error rate, and a required throughput value, wherein calculating the data rate of the WLAN based on the estimated available bandwidth, the required throughput value, and the target packet error rate includes: multiplying the required throughput value by a multiplier to take into account the target packet error rate, and then dividing the result by the estimated available bandwidth; and selecting a power amplifier bias voltage at the WLAN device that is the minimum determined from a look up table of power amplifier bias voltage and data rate for the data rate.
