Abstract
A system including a plurality of filter modules to respectively communicate with a plurality of antennas, filter signals from channels other than a communication channel of a first wireless network, where the communication channel includes a first channel and a second channel, and generate a plurality of signals. A sensing module senses, based on the plurality of signals, whether radio frequency signals from a second network are present in at least one of the first channel and the second channel, and generates a plurality of control signals indicating presence or absence of the radio frequency signals in at least one of the first channel and the second channel. A channel identification module determines, based on the plurality of control signals, availability of the first channel and the second channel in response to whether the radio frequency signals are present in the first channel and the second channel.
