Abstract:
1. A system for providing wireless spread spectrum communication, comprising: a base station transceiver capable of wireless spread spectrum communication with a plurality of mobile wireless transceivers via a wireless network, each of the plurality of wireless mobile transceivers employing one of a first data rate and a second data rate based upon an evaluation of radio frequency operating conditions of the wireless network, the first data rate being higher than the second data rate, the evaluation of the radio frequency operating conditions comprising an evaluation of a signal strength measurement, the evaluation of the signal strength measurement comprising a weighted signal strength measurement that emphasizes lower signal strength measurements of fading signals; the base station transceiver transmitting one or more messages usable by the plurality of mobile transceivers in performing the evaluation of radio frequency operating conditions of the wireless network; and a particular wireless mobile transceiver of the plurality of wireless mobile transceivers cycling between a power saving state and an active state over predetermined time intervals, the particular wireless mobile transceiver returning to the power saving state from the active state if the particular wireless transceiver receives no transmission directed to the particular wireless mobile transceiver while in the active state for a predetermined time interval.
