Patent ID: 7434076

Claim:
A wireless communication device, comprising: a plurality of interface circuits coupled to respective antennas, wherein each of the plurality of interface circuits comprises: a physical device that recognizes the signal provided in a format unique to that interface circuit, said signal having characteristics selected from a group consisting of a signal strength exceeding a threshold, and a bit rate within a pre-determined range; an amplifier; and a clock recovery circuit having an oscillator; a detector coupled to the interface circuits for detecting a signal recognizable by a first one of the interface circuits and for providing power to the first one of the interface circuits while removing power from other interface circuits, wherein the detector provides power to the amplifier and oscillator if the physical device recognizes the signal, otherwise the amplifier and oscillator do not receive power; and a controller coupled to receive input via a graphical user input to select either the first one of the interface circuits or a second one of the interface circuits and for providing power to the first one or the second one of the interface circuits while removing power from other interface circuits, wherein the controller provides power to the amplifier and oscillator regardless of whether the physical device recognizes the signal if the controller selects the interface that comprises the amplifier and oscillator.
