Huawei UBBPFW 024RHK WD2DUBBPFW10 BaseBand Processing and Interface unit

Distributed Base Station DBS3900:
This modular unit is designed to be installed far from other units — speeding site selection and network construction and saving investment in repeaters. It enables flexible coverage along railway lines, especially tunnels and bridges. It consists of a Baseband Unit (BBU) and a number of Remote Radio Units (RRUs), creating a single powerful cell over multiple sites.
The DBS3900 can support both GSM-R and eLTE. The GSM-R system can be upgraded to eLTE for Railway by software — there’s no need to replace hardware. Its low power consumption makes it possible to be powered by green energy — solar power, wind power, and biogas.
