Patent ID: 7155247

Claim:
A wireless communication network, the network comprising a plurality of spatially distributed communication devices, each for transmitting wireless signals carrying frames, each device being arranged to process frames from signals only when a strength of the signals exceeds a carrier detection threshold, each device being arranged to defer an intended transmission upon detection of a wireless signal with a strength greater than a defer threshold prior to the intended transmission, a subset of the devices being access point devices and a remainder of the device being station devices, each arranged to communicate with an own associated one of the access point devices, the network comprising: a measuring circuit for performing a first measurement of a first signal strength of signals from access point devices and a second measurement of a second signal strength of signals from station devices associated with a first one of the access point devices; a threshold adjustment circuit for first setting the carrier detection threshold of a first one of the access point devices above the first signal strength obtained from the first measurement, the second measurement being performed when said first setting has taken effect, the threshold adjustment circuit subsequently setting the defer threshold of the first one of the access point devices and/or one or more of the station devices associated with the first one of the access point devices below the second signal strength obtained from the second measurement.
