Patent ID: 7564878

Claim:
A method of operating a wireless network, comprising: detecting at least one signal of an external radio source, by a network device of said wireless network, while data is transmitted over the wireless network and said network device does not send data to another network device of said wireless network; changing a communication channel or frequency band, if said at least one signal overlaps with a currently used communication channel or frequency band; and setting a transmitting power level of said network device such that a receiving power level at said another network device lies between a first threshold and a second threshold, wherein in the step of setting the transmitting power level, said second threshold represents a detection level of radar signals, radar signals having a higher signal level than said detection level are detectable with a first detection rate, and radar signals having a lower signal level than said detection level are detectable with a second detection rate, said first detection rate being higher than said second detection rate.
