ABSTRACT:
A base station is operable in a local area communication radio network within the coverage of a wide area communication radio network. The base station comprises a code generator configured to generate an acquisition code, and a modulator configured to modulate the acquisition code onto an acquisition signal to be broadcast by the base station. The acquisition signal is broadcast over a listening channel of the wide area communication radio network. The acquisition code associated with the local area communication radio network is different from all acquisition codes used by the wide area communication radio network.
