Abstract
An adaptive hopping system and method using preestablished frequency assignments in a plurality of time slot groups is used to allow all units to be manufactured with the same preset frequency assignments. The preset frequencies are such that there is a minimum distance, for example 2 MHz, between any adjacent time slot in the same time slot group and between corresponding time slots of a next adjacent time slot group. When a time slot in a time slot group is marked (for example for poor communication) the same time slot in the next adjacent time slot group is used in place of the marked time slot group.
