Title (EN) BASE STATION WITH ANTENNA, INCLUDING AN AMPLIFIER, LOCATED AT A DISTANCE FROM THE STATION
(FR) STATION DE BASE A ANTENNE, COMPRENANT UN AMPLICATEUR, SITUEE A DISTANCE DE LA STATION DE BASE
Abstract: front page image
(EN)The present invention relates to a base station (BTS) of a radio system, comprising a base station equipment (2) including at least one transmitter unit (TX), and antenna means (3) adapted at a distance from said base station equipment (2) and connected by at least one cable (4) to the transmitter unit (TX) of said base station equipment for receiving signals fed by said transmitter unit (TX) and for forwarding said signals to receiver units within the radio coverage area of the base station (BTS). The antenna means (3) of the base station include amplifying means (8) for amplifying the signals received from the transmitter unit (TX) via said cable (4) and for forwarding the amplified signals to said receiver units. Thus the radio coverage area of the base station can be increased without simultaneously increasing the feeder losses from transmitter to antenna.
(FR)La présente invention concerne, dans un système radio, une station de base (BTS) constituée, d'une part d'un équipement station de base (2) comportant au moins un module émetteur (TX), et d'autre part d'un dispositif d'antenne (3) qui est installé à distance de l'équipement station de base (2) et qui est connecté par au moins un câble (4) au module émetteur (TX) de l'équipement station de base (2) de façon à recevoir les signaux fournis par le module émetteur (TX) et à faire parvenir ces signaux aux modules récepteurs se trouvant dans la zone de couverture radio de la station de base (BTS). Le dispositif d'antenne (3) de la station de base comporte un amplificateur (8) permettant, d'une part l'amplification des signaux reçus via le câble (4) en provenance du module émetteur (TX), et d'autre part l'acheminement des signaux amplifiés à destination des modules récepteurs. Il en résulte qu'on peut ainsi accroître la zone de couverture radio de la station de base sans augmenter de ce fait les pertes se produisant dans le câble d'antenne alimenté par l'émetteur.
