Abstract: Systems and methods that provide wireless communications are provided. One or more of the systems and methods may include, for example, selecting a lower data rate or a higher data rate based upon at least an evaluation of the operating conditions of a radio network. The evaluation may include, for example, computing a weighted signal strength measurement in which the weighting gives emphasis to the lower signal strength measurements of fading radio frequency signals.

Abstract: In an exemplary communication system, a multiplicity of mobile terminals are to share a communication link with a host processor communicating through base transceivers. The mobile terminals evaluate communication signals being transmitted to one or more of the mobile transceivers and according to the evaluation of such signals, each mobile terminal independently selects a relatively high data rate or a lower more conservative data rate for communication with the host processor. The mobile terminal enters a dormant state after a fixed period elapses during which the mobile unit is not engaged in communication with the base station. Periodically, the mobile terminal reenters active state in receive mode for a brief interval and if no polling signal or other message directed to the mobile terminal is present, the mobile terminal returns to dormant state.

Abstract: The present invention relates to a system and method for providing radio frequency communication of data collected by a multiplicity of mobile transceiver units to a base transceiver. The system comprises the base transceiver and the mobile transceiver units being selectively operable at limited and increased data rates. The mobile units respond to transmissions by the base transceiver, and have means to evaluate the feasibility of responding at the increased data rate. The base transceiver effects a communication link with one or more mobile units. The mobile units for which a communication link has not been established receives the transmissions of the mobile units with which a communication link has been established. The mobile units evaluate for consistent reception of transmissions to one or more transceiver units. The mobile units which consistently receive transmissions at the increased data rate respond at the increased data rate when communication is directed thereto.
