Abstract

A dynamic carrier selection method and system permit units operating on a first carrier to change to a second carrier when performance of the first carrier becomes unacceptable. Carrier quality measurements are taken in which carrier quality is a function of interference and multi-path fading and carrier-signal strength. The carriers are ranked according to measured quality in a carrier candidate list. The carrier candidate list is used to permit units to determine which carrier they should switch to when the carrier there currently operating on is determined to have unacceptable performance. Carrier measurements are retaken in response to a carrier change by unit or a predetermined time period having elapsed.
