Patent ID: 8666319

Claim:
A method comprising: at a first wireless device that is configured to wirelessly communicate with one or more second wireless devices in a wireless network in a frequency band, receiving energy on a channel in the frequency band; analyzing received energy to detect interference on the channel, including two or more interferers in the frequency band; determining a type, a receive signal strength, and a duty cycle for each of the two or more interferers; adjusting a clear channel assessment threshold used when accessing the channel by an amount depending on the type of interference detected, the adjusting including: determining a proposed new channel assessment threshold individually for each interferer; and determining an overall clear channel assessment threshold from the proposed new channel assessment thresholds for the individual interferers; computing a projected throughput improvement based on the overall clear channel assessment threshold; and using the proposed new clear channel assessment threshold at the first wireless device and/or one or more second wireless devices.
