Patent ID: 7809394

Claim:
A wireless access point (AP) for use in a wireless network, comprising: a wireless transceiver to support wireless communication with wireless client devices in a vicinity of the wireless AP; and a client transmit power control unit to manage transmit power control activities for wireless client devices, said client transmit power control unit to cause said wireless transceiver to transmit to a first client device, after it is determined that the first client device should change a current transmit power level, a first packet having a first transmit power level and a second packet having a second transmit power level, wherein a difference in decibels between the first transmit power level and the second transmit power level is indicative of a desired transmit power level change in the first client device; wherein said desired transmit power level change in the first client device is indicated by a sign of said difference between said first transmit power level and said second transmit power level, wherein said desired transmit power level change is X decibels when said sign is positive and −X decibels when said sign is negative, where X is a predetermined increment or decrement value.
