WIRELESS SYSTEM FOR TRANSMITTING DATA BETWEEN A BASE STATION AND A RELAY ANTENNA OF A MOBILE TELEPHONY NETWORK

摘要

The invention relates to a wireless system for transmitting data between a base station and a relay antenna of a mobile telephony network. The system is characterized in that a link (17) comprises for the separating of the channels two filters (20, 22) having a lower isolation than the total predetermined isolation and in that the antennas (15) are dual-polarization antennas, each polarization being allocated to one of the two channels and in that the isolation provided by the filters (20, 22) and the antenna (15) are added together to obtain the total predetermined isolation. The invention is usable for mobile telephony network systems.
