Abstract
A synchronized frequency hopping method and apparatus for use in a cellular communication system where the cellular communication systems has a plurality of cells and a plurality of frequencies available to be assigned to the cells. At predetermined times, cells in the system synchronously change or hop to a new frequency. The new frequency to which a cell hops to may be a function of the present frequency the cell is assigned. In addition, synchronized frequency hopping may occur at predetermined intervals and the pattern of hopping may periodically repeat. This technique limits the period of time a non-system source of interference may impair communications in any cell since the cell hops to different frequencies periodically.
