Patent ID: 8467284

Claim:
A method for implementing a scalable architecture for wireless devices, comprising: selecting, by a first wireless device, a first channel on which to transmit, wherein: the first channel is selected from a first set of channels having a first bandwidth, the first set of channels is one of a plurality of sets of channels, each set of channels of the plurality of sets of channels comprises channels of the same bandwidth and the bandwidth of the channels of each set of channels is different from the bandwidth of the channels of the other sets of channels, and the one or more channels of each of the plurality of sets of channels is formed from a number of contiguous bandwidth sub-bands from a set of sub-bands, each sub-band of the set of sub-bands being of substantially equal bandwidth and comprising substantially different frequencies with respect to the other sub-bands in the set of sub-bands; transmitting, by the first wireless device, on at least a first sub-band of the first channel; receiving, by the first wireless device, a signal transmitted by a second wireless device on at least one sub-band of a second channel, wherein the at least one sub-band comprises the first sub-band and wherein: the second channel was selected by the second device based on one or more factors present in an operating environment where the second wireless device resides, the second channel was selected from a second set of channels of the plurality of sets of channels, the second set of channels having a second bandwidth that is different from the first bandwidth, and the second channel of the second set of channels comprises the first sub-band.
