1. A system for voice and data communication, within a localized area, between individuals and stations that may be either fixed or mobile within said area, said system comprising:

  • a plurality of mobile transceiver devices, said mobile transceiver devices having means for transmitting and receiving low power radio frequency transmissions, each of said mobile transceiver devices uniquely associated with an individual user and having means for transmitting a radio frequency identification signal;

    a plurality of fixed transceiver devices, said fixed transceiver devices having means for transmitting and receiving low power radio frequency transmissions, each of said fixed transceiver devices uniquely associated with an individual user and having means for transmitting a radio frequency identification signal, each of said fixed transceiver devices further identified with a specific location within said localized area;

    a plurality of transceiver stations, each of said transceiver stations comprising;

    a radio frequency transceiver;

    a communication switching device;

    a plurality of antenna devices, said antenna devices capable of receiving and transmitting low power transmissions to and from said mobile and fixed transceiver devices located within a communication cell surrounding said antenna, to and from said transceiver station; and

    a communication identification and control processor for tracking said mobile and fixed transceiver devices within said communication cells by recognizing said identification signals and further for identifying communications paths between each of said fixed transceiver devices and at least one of said mobile transceiver devices; and

    a keyboard input device, said keyboard input device for modifying said identification and location information and further for modifying said communication pathsat least one control and relay station, said control and relay station comprising;

    a microprocessor;

    a plurality of data communication ports;

    a plurality of voice communication ports; and

    a communication identification and control processor for receiving and storing locational information on each of said plurality of mobile and fixed transceiver devices, said locational information communicated from said plurality of transceiver stations, said locational information for appropriately routing and relaying communications between said mobile and fixed transceiver devices and said transceiver stations;

    said control and relay station in hardwire communication with each of said transceiver stations, said control and relay station having means for relaying said low power transmissions from and between said transceiver stations.
