Abstract

La présente invention a trait à un système de communication qui fournit un accès dans une portion analogique d'un système de réseau local sans fil, notamment dans sa section de propagation/rayonnement RF. Le réseau comporte un module d'entrée sans fil et un point d'accès sans fil en interface avec un réseau de télédistribution au niveau du module d'entrée sans fil. En outre un unité de réseau local sans fil Wi-Fi intérieure améliorée est connectée au réseau de télédistribution. Le module d'entrée sans fil comporte une porteuse aval apte à la détection de signaux de liaison montante et la retransmission des signaux de liaison montante en renvoi vers le parcours en aval. Ainsi, des signaux transmis selon le protocole de communications de terminal de réseau local sans fil traversent le réseau de télédistribution, sans modification, utilisant un réseau à accès multiple par détection de porteuse et évitement de collision.
