CA 2287457

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.

L'invention concerne un répéteur de signaux radio, utilisé de préférence sous forme d'un répéteur portatif dans des réseaux radio numériques cellulaires. Les signaux radio reçus par les liaisons descendante et/ou montante du répéteur sont démodulés et les flux de données numériques ainsi obtenus sont à nouveau modulés selon les normes appropriées, amplifiés et retransmis. Une unité intelligente de contrôle surveille les communications de signalisation dans le réseau radio et syntonise automatiquement les canaux de fréquence transmis par le répéteur avec les canaux utilisés dans une cellule radio avoisinante afin de transférer (hand-over) la liaison radio vers une nouvelle cellule radio.
