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

摘要： An economical, compact digital/analog wireless data telemetry system includes either an analog transceiver or a digital packet data (e.g. CDPD) unit coupled with a portable computing device to provide a Mobile Data messaging and location device. The wireless data telemetry system is well suited for use in many possible applications, one application, vehicle location, provides an exemplary embodiment. In broadest terms, the system utilizes a plurality of analog RF channels for transmitting Mobile Data Packet Protocol (MDPP) packets between a tower site controller or remote base and number of mobile data units. The radio links between the tower site and the mobile data units are full duplex analog RF data transmission links utilizing full duplex receivers and transmitters at each installation. The operation of the combination of elements is the novel focus of the present invention. Particularly, the mobile data unit includes a main unit comprising RF and data boards and connections for an external GPS receiver and an RF antenna for transmission of data telemetry packets to a base station. The base or dispatch station receives data in MDPP format from a plurality of mobile units and organizes that information into a database which can be readily stored and manipulated in a central web site server for access by users or customers.
摘要翻译：经济，紧凑的数字/模拟无线数据遥测系统包括与便携式计算设备耦合的模拟收发器或数字分组数据（例如CDPD）单元，以提供移动数据消息和定位设备。无线数据遥测系统非常适用于许多可能的应用，一个应用，车辆位置提供了一个示例性实施例。最广泛地讲，该系统利用多个模拟RF信道来在塔站点控制器或远程基站与移动数据单元数之间传输移动数据分组协议（MDPP）分组。塔站点和移动数据单元之间的无线电链路是在每次安装时利用全双工接收机和发射机的全双工模拟RF数据传输链路。元素组合的操作是本发明的新颖重点。特别地，移动数据单元包括主单元，其包括RF和数据板以及用于外部GPS接收器的连接和用于向基站传送数据遥测分组的RF天线。基站或调度台从多个移动单元接收MDPP格式的数据，并将该信息组织到数据库中，该数据库可以容易地存储和操纵在中央网站服务器中以供用户或客户访问。
