Abstract

A repeater for radio signals is preferably designed for mobile use in digital cellular radio networks. The radio signals received in the down-link and/or up-link of the repeater are demodulated, and the thus obtained digital data flows are then remodulated in conformity with the prevailing norms, amplified and retransmitted. An intelligent control unit monitors the signalling traffic in the radio network and automatically tunes the frequency channels transmitted by the repeater with the channels used in the neighbouring radio cell, thus enabling a hand-over of the radio connection to a new radio cell.
