Abstract: A device and method for wirelessly communicating over a transmission channel with one or more wireless devices. The device comprises a wireless network interface and a controller. The controller is configured to receive a wireless signal via the wireless network interface, if strength of the received signal is greater than a first threshold, determine that the channel is busy, and, if the strength of the received signal is not greater than the first threshold, but is greater than a second threshold that is lower than the first threshold, determine whether the received signal is intended for the device and if so, determine that the channel is busy.

Abstract: Management of receiver sensitivity in a packet based wireless communication system is achieved by controlling a clear channel sensing process which determines if the channel is clear for use, governed by a sensitivity to use of the channel. The sensitivity of the clear channel sensing process is effected by monitoring transmission performance over a plurality of emissions, and making adjustments to the sensitivity based on comparison of that performance with a performance criterion.
