RELAY SYSTEM AND A DEVICE USED IN A BUILDING AREA, SPECIFICALLY CONCERNED WITH REMOVING SHADING PLACES BETWEEN BUILDINGS, AND RESOLVING WEAK RADIO PHENOMENA AT LOWER BUILDING AREAS

摘要

PURPOSE: A relay system and a device used in a building area are provided to form a low-loss RF link between relay mother stations by using antennas having high-oriented radio features and exclusive radiating patterns, and to increase an isolation between transceivers of the relay mother stations, thereby easily restoring into high-density original signals by using a low-gain RF amplifier. CONSTITUTION: The first relay mother station(220) receives a communication signal from a base station(210), and fixes the received signal as a high-power signal which is sufficiently stable for being used in a building area. The first link antenna(221) transmits an output signal of the first relay mother station(220) to the second relay mother station(230). The first service antenna(222) transmits a portion of the output signal to a radio shading area of a building. The second relay mother station(230) receives the signal of the first relay mother station(220) from the first link antenna(221). The second link antenna(231) sends an output signal of the second relay mother station(230) to a next relay mother station. The second service antenna(232) transmits a portion of the output signal to a radio shading area of a new building.
