Abstract:
1. A subscriber access unit comprising: a transceiver for providing wireless communication of digital signals, the digital signals being communicated at a nominal data rate to a base station using at least one radio frequency (RF) channel via Code Division Multiple Access (CDMA) modulated radio signals, with a plurality of subchannels being made available by the base station within each CDMA RF channel, each subchannel having a data rate less than the nominal data rate of the digital signals; a bandwidth manager connected to said transceiver, and being allocated available subchannels by the base station on an as-needed basis, with a number of allocated subchannels changing during a given session; and said transceiver, when powered on but not actively sending data, providing an idling mode connection on a reverse link to the base station, the idling mode connection enabling subchannels to be reallocated without reestablishing a bit synchronization with the base station.
