ABSTRACT:
Frequency hopping techniques which provide greater interference averaging are described. Cells having the same hopping sequence select sequence offsets pseudo-randomly in a manner which ensures that stations within cells select different channel frequencies, but also that as between such cells, interferers change between hops. This can be accomplished by, for example, providing each station with a unique identifier that can be used in conjunction with a pseudo-random number to select from the set of hopping sequences assigned to the cell.
