MULTI-SECTOR IN-BUILDING RELAY SYSTEM

摘要

PURPOSE: A multi-sector in-building relay system is provided to make smooth soft handoff by using a dedicated frequency in a building and dividing each floor by selector. CONSTITUTION: A master transmitter(210) outputs each sector signal which has been converted into a different transmission intermediate frequency-band signal to the same line. Each slave receiver receives a multi-sector signal, extracts an allocated sector signal, converts the extracted sector signal into a radio frequency signal, and outputs it to an antenna. Each slave transmitter(310) outputs the sector signal to the same line. A master receiver(220) converts a separated sector signal into a receiving carrier frequency signal and outputs it to a base station. A distributing unit(120) receives the sector signal from the plurality of slave transmitters(310) and transmits them to the master receiver.
