Title (EN) RADIO FREQUENCY SIGNAL BOOSTERS FOR HIGH FREQUENCY CELLULAR COMMUNICATIONS
(FR) SURAMPLIFICATEURS DE SIGNAUX RADIOFRÉQUENCE POUR COMMUNICATIONS CELLULAIRES À HAUTE FRÉQUENCE
Abstract:
(EN) RF signal boosters for high frequency cellular communications are provided herein. In certain embodiments, a signal booster system includes an outdoor base station antenna for communicating with base stations of a cellular network, and an indoor mobile station antenna for communicating with user equipment (UE) of the cellular network, such as mobile phones. The signal booster system further includes a signal booster that is coupled to the indoor mobile station antenna via a cable. The signal booster includes booster circuitry for providing amplification to RF signals associated with one or more uplink and downlink channels of the cellular network. The signal booster further includes a signal conversion circuit operable to provide signal conversion such that RF signals provided to and received from the indoor mobile station antenna via the cable are of lower frequency relative to RF signals provided to and received from the outdoor base station antenna.
(FR) L'invention concerne des suramplificateurs de signaux RF pour des communications cellulaires à haute fréquence. Dans certains modes de réalisation, un système de suramplification de signaux comprend une antenne de station de base extérieure pour communiquer avec des stations de base d'un réseau cellulaire, et une antenne de station mobile intérieure pour communiquer avec un équipement d'utilisateur (UE) du réseau cellulaire, tel que des téléphones mobiles. Le système de suramplification de signaux comprend en outre un suramplificateur de signal qui est couplé à l'antenne de station mobile intérieure par l'intermédiaire d'un câble. Le suramplificateur de signal comprend un montage de circuits de suramplification pour fournir une amplification à des signaux RF associés à un ou plusieurs canaux de liaison montante et de liaison descendante du réseau cellulaire. Le suramplificateur de signal comprend en outre un circuit de conversion de signal utilisable pour fournir une conversion de signal de telle sorte que des signaux RF fournis à et reçus de l'antenne de station mobile intérieure par l'intermédiaire du câble ont une fréquence inférieure à celle de signaux RF fournis à et reçus de l'antenne de station de base extérieure.
