Problems solved by technology

[0005] Therefore, the RF signal (analog signal) transmitted from the above-mentioned base station is distorted by noise or the like during transmission to the main device, and the main device receives the degraded RF signal, and the main device converts the degraded RF signal It is a digital signal and then transmitted to the above-mentioned multiple distribution devices. Therefore, the above-mentioned multiple distribution devices receive signals distorted by noise, etc., and finally, the terminal located in the shadow area covered by the above-mentioned multiple distribution devices receives a problem of low-quality signals. , there is an issue that degrades call quality

Abstract

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.

Description

technical field [0001] The present invention relates to an indoor relay system, specifically, in a distributed base station system, the signal transmission between the base station control unit and the remote wireless base station device installed in the building and the communication between the remote wireless base station device and A technique for signal transmission between discrete devices in each of a plurality of shaded areas (blind areas, shadow areas) without going through an analog signal conversion process. Background technique [0002] Generally, a mobile communication service system consists of base stations, base station controllers, switching centers, and terminals. The base station and the terminal communicate in a certain frequency band, and each base station has a certain communication radius. Therefore, a plurality of base stations are appropriately arranged so that the communication radius of each base station overlaps with each other, thereby expanding...
