<p>A personal communication system for communication with another entity uses a global positioning receiver, phone book storage, and audio input as alternative forms of generating position data. A (44) transmitter communicates a service request and the position data to the other entity, which in turn, relays the request to the appropriate party. Alternatively, the personal communicator (40) may directly contact the desired individual. The personal communicator (40) also includes a plurality of command buttons (12) to control operation and a display (16) to provide the user with instructions and data. The personal communicator (40) also includes a sound generator (50) to generate a loud sound upon manual command by the user or by remote command from the other entity. The transmitter (44) can be an analog data link or part of any packet data radio communication link.</p> |
