Title (EN) WIRELESS RELAY APPARATUS AND WIRELESS RELAY SYSTEM
(FR) APPAREIL DE RELAIS SANS FIL ET SYSTÈME DE RELAIS SANS FIL
(JA) 無線中継装置及び無線中継システム
Abstract:
(EN) A wireless relay apparatus which can provide a wireless relay apparatus compatible with an MIMO system without changing the wiring of an already installed wireless relay apparatus or wireless relay system not compatible with the MIMO system, and which is able to minimize the costs that are generated in installing a wireless relay apparatus compatible with the MIMO system. In this apparatus, a second wireless apparatus (160) is connected to a first wireless apparatus (150) by a coaxial cable (170). The downlink signal wireless unit (111) caries out wireless processing of a downlink signal received at an antenna (102), and in this wireless processing, down-converts the downlink signal received at the antenna (102) to a frequency different than the frequency of the downlink signal received at an antenna (101). The duplexer (115) combines the downlink signal which was subjected to wireless processing at a downlink signal wireless unit (109) and the downlink signal which was subjected to wireless processing at the downlink signal wireless unit (111), and transmits the same using the same coaxial cable (170) to the second wireless apparatus (160).
(FR) L'invention porte sur un appareil de relais sans fil qui peut fournir un appareil de relais sans fil compatible avec un système MIMO sans changer le câblage d'un appareil de relais sans fil ou d'un système de relais sans fil déjà installé non compatible avec le système MIMO, et qui est capable de minimiser les coûts qui sont générés lors de l'installation d'un appareil de relais sans fil compatible avec le système MIMO. Dans cet appareil, un second appareil sans fil (160) est connecté à un premier appareil sans fil (150) par un câble coaxial (170). L'unité sans fil de signal de liaison descendante (111) réalise un traitement sans fil d'un signal de liaison descendante reçu au niveau d'une antenne (102), et dans ce traitement sans fil, convertit en abaissant sa fréquence le signal de liaison descendante reçu au niveau de l'antenne (102) à une fréquence différente de la fréquence du signal de liaison descendante reçu au niveau d'une antenne (101). Le duplexeur (115) combine le signal de liaison descendante qui a été soumis à un traitement sans fil au niveau d'une unité sans fil de signal de liaison descendante (109) et le signal de liaison descendante qui a été soumis à un traitement sans fil au niveau de l'unité sans fil du signal de liaison descendante (111) et transmet ceux-ci à l'aide du même câble coaxial (170) au second appareil sans fil (160).
(JA)  設置済みのMIMO方式に対応していない無線中継装置または、無線中継システムの配線を変更することなく、MIMO方式に対応可能な無線中継装置を提供することができるとともに、MIMO方式に対応可能な無線中継装置の設置に伴って生じる費用を抑制することができる無線中継装置。この装置では、第2の無線装置(160)は、第1の無線装置(150)と同軸線(170)により接続される。下り信号無線部(111)は、アンテナ(102)において受信した下り信号の無線処理を行うとともに、無線処理において、アンテナ(101)において受信した下り信号の周波数と異なる周波数にアンテナ(102)において受信した上り信号をダウンコンバートする。共用器(115)は、下り信号無線部(109)において無線処理を行った下り信号と、下り信号無線部(111)において無線処理を行った下り信号とを周波数多重して、同一の同軸線(170)を用いて第2の無線装置(160)へ伝送する。
