Abstract
A channel scanning arrangement for automatically selecting an available one from multiple communication channels with a minimum probability of interference and without delay is provided for a cordless telephone. This arrangement avoids causing and receiving interference on a channel by scanning all available channels when the cordless telephone is not in use and prioritizing these channels in the order of most recent observed activity. When a user of a handset unit associated with the cordless telephone desires to communicate with a base unit, also associated with the telephone, the handset and base units communicate briefly on the last used channel. When communication between the handset unit and the base unit has been established, the base unit moves and also causes the handset unit to move to the channel that has been unused by an other cordless telephone for the longest period of time.
