Patent ID: 7848741

Claim:
A method, comprising: (a) receiving electromagnetic energy including network transmissions in a plurality of channels in an available communications bandwidth of a single wireless communications system type and interference signals from interference sources; (b) converting the received electromagnetic energy to RF signals including at least a first sub-band and a non-overlapped second sub-band of said available communications bandwidth of the network transmissions, each sub-band containing a sub-plurality of said plurality of channel frequencies; (c) generating a first clock signal from said RF signals in said first sub-band; (d) generating a second clock signal from RF signals in said second sub-band, wherein said first and second clock signals have respective first and second frequencies associated with said interference signals; (e) identifying said one or more interference sources based on said first and second frequencies; and (f) avoiding use of channels in either said first sub-band or said second sub-band based on said identified one or more interference sources.
