Modular analog wireless data telemetry system adapted for use with web based location information distribution method and method for developing and disseminating information for use therewith

摘要: An economical, compact wireless data telemetry system includes a transceiver coupled with portable computing device to provide mobile messaging and location information delivery system. The is well suited for use in many possible applications, one application, vehicle location, provides an exemplary embodiment. In broadest terms, the utilizes plurality of analog RF channels transmitting Mobile Data Packet Protocol (MDPP) packets between tower site controller or remote base number units. radio links units are full duplex transmission utilizing receivers transmitters at each installation. operation combination elements novel focus present invention. Particularly, unit main comprising circuits GPS receiver antenna time-stamped station. dispatch station receives MDPP format from organizes that into database stored manipulated central web server access by users customers.
