BTS3900 Huawei GSM-R Indoor Macro Base Station

Overview

Brand Name:  Huawei

Model Number:  BTS3900B

Components 

The main components of the BTS3900B consist of the baseband processing board, RF module, and plastic housing. The baseband processing board processes baseband signals and implements main control and transmission functions, and the RF module transmits, receives, and processes RF signals. If AC power supply is used, the power adapter is required for the BTS3900B. The power adapter converts the AC power into the working voltage of the BTS3900B. If the PoE mode is adopted, external PoE power equipment must be configured. The PoE power equipment supplies power to the BTS3900B through the Ethernet cable. In this case, the power adapter is not required. The BTS3900B can be employed with built-in antennas or external antennas. Figure 2-1 shows the BTS3900B with external antennas and BTS3900B with built-in antennas. 

Flexible Applications with IP Transport
The BTS3900B supports the IP transport and IPSec protocol, ensuring the data security during
the transmission. Adopting the IP transport, the BTS3900B can fully use the existing IP
network resources, reducing the transmission cost significantly. The BTS3900B can easily
access the IP network, facilitating flexible applications. The BTS3900B can provide private
coverage for SMEs and small office buildings. It can also work with the existing indoor
coverage networks, improving the indoor coverage in places such as malls, buildings, and
parking lots. This enriches the GSM network solutions.


Energy-Saving and Green Communication Design
The low power consumption design and natural heat dissipation mode enable the BTS3900B
to work in energy saving and mute mode. The maximum power consumption of the
BTS3900B in dual-carrier configuration is only 32 W. The BTS3900B supports a wide range
of AC input voltage from 90 V AC to 264 V AC. Therefore, the normal AC power can be
supplied to the BTS3900B for flexible deployment. The BTS3900B can also work in Power
over Ethernet (PoE) mode. Through the Ethernet cable, the BTS3900B can obtain power from
the PoE power equipment. In PoE mode, the BTS3900B supports a maximum of one carrier,
and the Ethernet cable supports a maximum distance of 50 m.The BTS3900B works in mute
mode. Therefore, the indoor BTS3900B does not affect the life and work of people,
facilitating flexible site selections. 

General

The BTS3900B is small and compact, works in mute mode, and occupies a small space. Therefore, the BTS3900B can easily be installed in a proper place without affecting the life and work of people. The BTS3900B can be installed on a wall, in the void of a suspended ceiling, or on a ceiling according to actual conditions. The BTS3900B can be easily and quickly installed with few common tools. 

 Application of the BTS3900B

 The BTS3900B can flexibly meet the requirements for blind spot coverage and private coverage. The CAPEX on a site is small. Therefore, the BTS3900B is an excellent supplement to the existing network solution. The BTS3900B has an outstanding performance in the blind spot coverage and small private coverage. In addition, the BTS3900B supports IP transport, AC input, and fast deployment. Therefore, the BTS3900B is also applicable to temporary emergency communications.
