System and method for wireless exchange of data in a non-real-time data communications system

The present invention pertains to the field of wireless data communications systems, and more specifically to a system and method for non-real time communication between a fixed base station and a plurality of remote transceivers. A method of non-real-time two-way wireless data communications using a synchronous time division multiplexed architecture (TDMA) protocol in a communications system having a plurality of fixed base stations (BS) and a plurality of receiver/transmitters (RTs), wherein a BS controller dynamically changes a plurality of data blocks in both an uplink and a downlink data frame, a plurality of data rates, a plurality of signal modulation techniques, and a plurality of frequencies according to a computer analysis of received signals in order to provide optimization of the system. The method further includes overhead data reduction techniques using abbreviations for identification character strings and concatenations of downlink data messages. Embodiment of a novel emergency alarm resolution techniques and a plurality of message collision avoidance techniques improves response times for remote transmissions.
