WirelessUSB™ Protocol 2.2
2.1.7 Channel Selection Algorithm
The channel selection algorithm produces a subset containing 13 of the possible 78 channels. The
channel selection algorithm is based on the network ID, with each channel in the subset being six
megahertz from the nearest neighboring channels in the subset. This algorithm reduces the possibil-
ity of multiple bridges selecting the same channels in the same order at the same time.
