Abstract
Abstract A method and apparatus is offered of exchanging a communicated signal at a base site with a communication unit on an indexed frequency of a frequency hopping communication system. The method includes the steps of transceiving, through a first base site transceiver, a first communicated signal within a first frame on a first frequency of the indexed frequency; and, while transceiving within the first frame, tuning a second, extra base site transceiver to an indexed frequency of a second frame. The second transceiver may then be used to transceive a signal within the second frame while the first transceiver is tuned to the next indexed frequency. Additional communication units may be added by adding one base site transceiver per communication unit while maintaining a single extra transceiver per frame. The extra transceiver, during each frame, is tuned to the next frequency in the frequency hopping sequence and indexing the communication units, transceiving from within different steps of the sequence, from transceiver to transceiver.
