Patent ID: 7184777

Claim:
A radio sensor device comprising: a. a first radio receiver capable of receiving radio signals in a radio frequency band; b. a spectrum analysis system coupled to the first radio receiver that produces spectrum activity information representative of the activity in the frequency band; c. a baseband signal processing section that demodulates baseband signals transmitted by other devices on a wireless network in the frequency band according to a communication protocol; d. a second radio receiver coupled to the baseband signal processing section that receives signals transmitted on the wireless network and couples received signals to the baseband signal processing section; and e. a processor coupled to the spectrum analysis system and to the baseband signal processing section, wherein the processor executes one or more programs to analyze packets transmitted on the wireless network in the frequency band based on signals demodulated by the baseband signal processing section and to classify radio signals occurring in the frequency band based on the spectrum activity information output by the spectrum analysis system.
