1 Introduction 1.1 Overview

This document contains the following information: DBS3900 typical configurations and

function modules, and physical specifications for other products.

This document is intended for personnel who have a basic knowledge of the DBS3900 and

DBS3900-related features.

1.2 Version Difference

DBS3900 V301R013 is the first DBS3900 version that matches GSM-R 5.0.

eWSE GSM-R 5.0 DBS3900 Configuration Principles 2 Application Overview

2 Application Overview

The DBS3900 adopts the remote radio frequency technology and features flexible installation, low power consumption, easy acquisition, and small floor area.

Adopting the remote radio frequency technology, the DBS3900 forms two modules that can

be installed, expanded in capacity, and evolved independently to meet the deployment requirements of GSM-R networks. This decreases the difficulties for telecom operators in the

following aspects: site acquisition, equipment room construction, and device transportation

and installation.

Each BBU3900 configured with the dual-density RRU (DRRU) supports a maximum of 36

TRXs.
