ABSTRACT:
The method comprises transmitting an initiating signal in the form of a bit pattern as a continuous burst from one radio unit to the other. The pattern incorporates a preamble pattern and a security code having a plurality of bit sequences. Each sequence is transmitted a number of times. The received security code is compared with stored codes in the other unit, and if a matching pair is identified a response signal is transmitted from the other unit to said one unit. The response signal incorporates the preamble pattern for establishing synchronization between the radio units.
