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.
Consisting of only BBUs and RRUs, requires only a small number of spare parts and reduces maintenance costs
RRUs can be installed on a tower, reducing feeder costs and feeder loss and increasing system gain by 3 dB to 5 dB, remote radio frequency technology enables distributed RRU installation, which is perfect for railways.
Multiple-site cells extend cell coverage areas and reduce the number of inter-cell handovers previously required
|Working Frequency Bands||
|Networking||A maximum of 12 subsites are allowed to serve one cell. Each subsite supports three RRUs.|
