Product Version The following table lists product versions involved in this document. Product Name BTS3900 GSM (BTS3900 for short) BTS3900A GSM (BTS3900A for short) BTS3900L GSM (BTS3900L for short) DBS3900 GSM (DBS3900 for short) Product Version V100R013C00 V100R013C00 V100R013C00 V100R013C00 Intended Audience This document is intended for: l l l Network planners Field engineers System engineers Organization 1 Changes in the 3900 Series GSM Base Station Technical Description Issue 12 (2012-12-30) Huawei Proprietary and Confidential Copyright © Huawei Technologies Co., Ltd. ii 3900 Series GSM Base Station Technical Description About This Document This section describes changes in the 3900 Series GSM Base Station Technical Description of each version. 2 Overview 3900 series base stations adopt the cutting-edge modular design for different modes and are managed by various systems. With simple components, they can be installed and deployed easily and fast. With comprehensive functions and remarkable performance, they can meet requirements in various scenarios. In addition, they are diversified by flexibly combining functional modules and auxiliary devices. 3 BTS System Principle The BTS consists of the BBU3900 (BBU for short), RF modules, and the antenna system. Its functional subsystem includes the control system, transport system, monitoring system, RF system, antenna system, and power supply system. 4 Control and Transport Systems The functions of the control and transport systems are provided by the BBU. The control system manages the entire BTS system in a centralized manner, including signaling processing, operation and maintenance, and system clock. The transport system provides physical ports connecting the BTS and the transport network. 5 RF System The functions of the RF system are provided by RF modules including the radio frequency units (RFUs) that are used in macro base stations and remote radio units (RRUs) that are used in distributed base stations. The RF system performs modulation, demodulation, data processing, and combination and division of RF and baseband signals. 6 Antenna System The antenna system consists of antennas, feeders, jumpers, the Tower Mounted Amplifier (TMA), the Bias Tee (BT), and the GSM Antenna and TMA Control Module (GATM). It transmits and receives RF signals. 7 Operation and Maintenance Operation and Maintenance (OM) covers management, monitoring, and maintenance of the software, hardware, and configuration of the BTSs. In addition, diversified OM modes are provided in various scenarios. 8 External Reference Clock Sources The BTS supports multiple external reference clock sources, including the IP reference clock, E1/T1 reference clock, synchronous Ethernet reference clock, BITS reference clock, and GPS/ RGPS reference clock. If a BTS fails to obtain clock signals, it works in free-run mode for a certain period of time. 9 Surge Protection Specifications This section provides surge protection specifications for the BBU, RF modules, and each type of base stations. 10 Technical Specifications This section provides technical specifications for RF modules.

Chain Strip areas that are sparsely populated such as areas along highways and railways Areas where network architecture, site distribution, and subscriber distribution are complicated such as an area where large-scale coverage overlaps with hot spot areas or small-scale coverage. A wild range of areas. Because of its self-healing capability, this topology is recommended when a route is available. This topology helps reduce expenditure on transmission device, engineering, and leased transmission cables. Compared with the star topology, this topology requires fewer transmission cables.

If the output power of 60 W is required, the related license must be obtained. After design optimization, the 8PSK and GMSK modulation schemes enable the same output power for each carrier on the RRU3942 when any of the S1 through S6 configurations is used. When the S7 or S8 configurations is used, the license controlling the GBFD-118104 Enhanced EDGE Coverage feature must be obtained. Otherwise, the 8PSK and GMSK modulation schemes cannot enable the same output power for each carrier on the RRU3942. l Factors such as the site-to-site distance, frequency-reuse factor, power control algorithm, and traffic model affect the gain achieved by dynamic power allocation. Therefore, in most cases, the network planning can be based on the power specification achieved by dynamic power allocation. l Before activating the dynamic power sharing feature, enable the DTX and power control functions.
