REMOTE WIRELESS BASE STATION DEVICE HAVING IN-HOUSE EXPANDABILITY AND IN-BUILDING RELAY SYSTEM

摘要

A remote wireless base station device having in-house expandability and an in-building relay system is disclosed. The remote wireless base station device according to one embodiment of the present invention includes: a CPRI/OBSAI signal processing unit that is connected to a base station control unit by means of a first cable and that transmits information to and receives information from the base station control unit using a first digital communication scheme; and a master UTP interface transceiver that converts a first digital communication type signal received from the CPRI/OBSAI signal processing unit into a second digital communication type signal without an analog signal conversion process, and converts the second digital communication type signal, received from a plurality of distribution devices that are connected to each other by means of a second cable and installed at the shaded regions of buildings, into the first digital communication type signal without an analog signal conversion process.
