Capacity of Channel Hopping Channel Stream on Cellular Digital Packet Data (CDPD)

Because voice cellular radio systems must maintain low blocking probabilities, almost 20% of cellular channel capacity is unused, even during the busy hour. A packet radio system can capture this unused capacity by hopping between idle voice channels, working independently of the voice base station and the cellular telephone switch. To optimize performance, the mobile data base station should select the idle channel with the least co-channel interference. By doing so, the base station will maximize the carrier-to-interference ratio at the mobile terminal and maximize throughput when automatic repeat-request protocols are used. For example, if the offered voice traffic at a 54-channel base station is 22 Erlangs, the data base station can achieve a throughput improvement of a factor of 2 and a coverage area increase of 47%
