1. A system for transmitting voice or data communications comprising a plurality of data packets between a plurality of remote units, each remote unit having a unique identifier;
- whereby each remote unit includes;
a memory for storing a unique identifier;
a transceiver for receiving a wireless communication and downconverting said received communication from RF to baseband, and for upconverting a baseband communication to RF for transmission as a transmit wireless communication;
a GPS receiver, for outputting a position signal;
a microprocessor, for receiving said position signal and said downconverted communication, and for generating said baseband communication;
whereby said microprocessor generates said baseband communication by constructing said data packets from a plurality of data fields, including sender information and receiver information, whereby said sender information includes;
the unique identifier of the sender, and information derived from said position signal;
and whereby said receiver information includes;
