ABSTRACT:
A cordless telephone arranged for operation in a frequency hopping system automatically modifies a frequency hopping sequence in the presence of interference detected on its in-use communication channels. Substitute alternative communication channels are identified and then substituted for those communication channels experiencing the interference without disruption of communications between a handset unit in the cordless telephone and its associated base unit.
