US 2019/0379443 A1 · NEXT GENERATION IN-BUILDING RELAY SYSTEM AND METHOD

Abstract

Provided are a next generation in-building relay system and method. The system includes: a 5G signal providing unit configured to down-convert a millimeter wave radio frequency signal to an intermediate frequency signal; a 5G master hub unit configured to convert the intermediate frequency signal into a radio over fiber (RoF) signal and transmit the RoF signal; an optical coupling unit configured to couple a digital optical signal output from a master hub unit and the analog optical signal output from the 5G master hub unit and transmit the coupled signal to an optical cable; and an optical distribution unit configured to separate the digital optical signal and the analog optical signal from the coupled signal, transmit the digital optical signal to a remote optical relay unit, and transmit the analog optical signal to distributed remote units.
