Distributed Base Station DBS3900
This modular unit is designed to be installed far from other units — speeding up 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 supports both GSM-R and eLTE. The GSM-R system can be upgraded to eLTE for Railway via software, with no need to replace hardware. Its low power consumption makes it possible to be powered by green energy, such as solar power, wind power, and biogas.
