ABSTRACT:
A transceiver receives channel control commands which communicate predictions of upcoming frequency bands that might be used for communication or which communicate activations of upcoming frequency bands and time units which will be used for communication. The transceiver includes a plurality of synthesizers which can be switched to control the frequencies at which a receiver and transmitter operate. When predictions are received, frequency IDs associated therewith are used in programming new frequencies into non-activated ones of the synthesizers. When each activation is received, a memory structure is programmed to identify one of the synthesizers, to record a frequency for programming into the identified synthesizer, and to record timing data describing when to program the identified synthesizer and when to activate the identified synthesizer. The memory structure is used to control the programming and switching of synthesizers which drive the receiver and the transmitter.
