This outdoor macro base station supports both GSM-R and LTE — the ideal solution for railways that want to prepare for evolution to an LTE broadband network. One of the most compact outdoor macro base stations in the industry, the BTS3900A features a large, scalable capacity and multi-mode applications that meet the requirements of long-distance railways.

The base station cabinet contains as many as six RF modules. These multicarrier modules support both Huawei’s GSM-R 5.0 and the company’s enterprise LTE (eLTE). Use of this multi-radio base station (and similar indoor base stations) maximizes versatility while minimizing site deployment costs.

BTS3900A includ :RFC(Radio Frequency Cabinet),APM30,BBC(Battery Backup Cabinet) and TMC(Transmission Cabinet).

Typical configuration of the BTS3900A:

APM30+RFC,DRFU(S444)/ GRFU(S121212): 20 minutes backup (24Ah)

TMC+RFC,Provide user equipment space, no backup power (site has DC power supply)

APM30+ RFC +BBC,DRFU(S444)/ GRFU(S121212): 5-hour standby (184Ah)

APM30+ RFC +TMC+BB,DRFU(S444)/ GRFU(S121212): 4-hour standby (184Ah) Description: The power consumption of the transmission cabinet is less than 200W.

Huawei's fourth-generation base station includes: indoor macro base station BTS3900, outdoor macro base station BTS3900A, distributed base station DBS3900

Application Scenarios Flexible combinations of the basic components and auxiliary devices can provide comprehensive solutions that are applicable to specific scenarios of operators, such as indoor centralized installation, outdoor centralized installation, outdoor distributed installation, or co-siting of base stations in different modes.
