In radio data systems where the preponderance of data message traffic is directed inbound (from remote to central), the outbound channel (i.e., the allocated RF frequency) is often under utilized. This condition would be compounded as additional bi-directional channels were needed to satisfy a given inbound data throughput require- ment. At some point, the totality ofthe unxwdbandwidth of the outbound channels would equal or exceed the usable bandwidth of one or more channels. This would be the case with conventional channel organization and contention protocols, where bi-directional channels are incrementally added until the peak throughput require- ments are met. At the same time, the unused bandwidth of the outbound channels increases, but remains inac- cessible for satisfying additional inbound demand.
