Abstract

A number of different communication systems A,B,C can operate within unlicensed frequency bands.(eg. 2.4GHz ISM band) using various protocols (eg. IEEE 802.11). Some devices (eg. access point (AP) 11,station (STA) 17 of System A) can use TPC and detect interference power levels from devices 15,19,21,23,25 in other systems B and C. If the interference detected is below a threshold system A may employ TPC. Interference may be detected based upon beacon transmissions from devices. If interference is detected, devices (eg. 11) may transmit messages to other systems/devices (eg. 15) to request that they reduce their power levels and thence reduce interference. Devices (15) may accede to or refuse these requests, or may enter into power setting negotiations. The request may be included in beacon messages.
