Abstract: A communications system having a plurality of different radio-types (528, 530 and 532) when integrated into a single node or control module (500) provides communications with a plurality of different end users (502, 506 and 508) having different transmission protocols. The steps involved comprise coupling the plurality of communication devices (528, 530 and 532) together via a bus (526) and coupling at least one processing unit (517) to the bus (526). Signals received by RF devices (528, 530 and 532) are communicated onto the bus (526) and processed by the processing unit (517) into processed signals. Processed signals comprise data and control information which are stored in memory (522). Thereafter, the processed signals stored in memory (522) are returned back onto the bus (526) for use by at least one of the plurality of communication devices (528, 530 and 532).

Abstract: An intelligent communcations node is capable of dynamically selecting frequency and time slot assignments for communications with remote communication devices having different communication protocols including different available frequencies and time slots in a TDMA system. A frequency agile transmitter and receiver combined with an adaptable time slot selector enables communications with remote devices utilizing different protocols. The time and frequency management capabilities of the node makes greater spectral efficiencies possible.
