1. An apparatus for transferring data between a source of information and a sink for information by a wireless linkage comprising:

  • a first transceiver unit connecting to said source of information and having an address;

    a second transceiver unit connecting to said sink for information and having an address;

    a control on each of said first and second units for placing them into a first linkage mode;

    a handshake protocol within each of said first and second units, placed into operation when the units are in said first linkage mode, which causes them to continuously attempt to handshake with another transceiver unit and exchange addresses by one broadcasting its address and by the other responding with its own address;

    said first and second units, following the successful execution of said address exchange handshake between them, placing themselves into a data communications mode where each communicates exclusively with the other and where said first and second units remain in said data communications mode indefinitely; and

    said units thereafter wirelessly transferring data in the form of packetized, error correctable, addressed data packets, and also transferring addressed acknowledgments of successful receipt of such data packets, to transfer data in an error-free manner between said source and said sink.
