RADIO COMMUNICATION SYSTEM

摘要

PROBLEM TO BE SOLVED: To solve a problem that a communication link between a base unit and one or more remote units is easily interrupted since a frequency selected for an operation is easily interfered from other RF generating sources such as a microwave device. SOLUTION: A system is constituted of a means for conducting communications between the base unit and the remote unit by using CDMA in one of a plurality of selected frequency channels and further a means for changing one of the frequency channels to another frequency channel in correspondence with interference in one of the frequency channels. Thus, a communication processing between the base unit and the remote unit is performed on the different frequency channel.
