Distributed Base Stations enable radio access for large to small
eLTE wireless private networks that provide services such as video
surveillance, data acquisition, and data transmission. The base
stations’ modular platform consists of a Base Band Unit (BBU3900)
and Remote Radio Unit (RRU). Both components feature flexible
installation, easy site deployment, low power consumption, and low
The DBS3900 supports bandwidth up to 100 Mbits/s, and provides higher data transmission rates for users.
High Performance Mobile Broadband Access Network
The DBS3900 supports high data rates. Downlink and uplink rates can reach up to 100 Mbit/s and 50 Mbit/s @ 20 MHz per cell, respectively. For coverage of remote sites such as offshore drilling platforms, the DBS3900 can provide ultra-long-distance coverage up to 100 kilometers. For railways, the DBS3900 provides up to 430 km/h high-speed train coverage.
World’s Leading Professional Broadband Trunking
Based on LTE technology, the Huawei DBS3900 is the world’s leading professional broadband trunking solution. Its advanced features include priority call, call hold, late entry, dynamic grouping, and fallback mode. In addition, the DBS3900 provides outstanding performance for traditional trunking with a group call setup time less than 300 ms and a pre-emptive priority call time less than 150 ms. Combining voice and real-time video trunking in the same base station reduces Capital Expenditure (CAPEX) costs compared to traditional trunking and data service solutions.
Multiband for Diversified Frequency Resources
The DBS3900 supports multiple frequency bands, including LTE-TDD
400 MHz/1.4 GHz/1.8 GHz/2.3 GHz and LTEFDD 800 MHz. Wide frequency
band availability simplifies network deployment and allows the
system to adapt to various frequency policies with higher
Multiple frequencies for eLTE Time Division Duplex (TDD) and Frequency Division Duplex (FDD) provide wider bandwidth availability
Flexible installation and simple site acquisition enables BBUs to be deployed indoors or out; RRUs can be mounted easily on a pole, tower, or concrete wall
Green communications networks deploy power consumption management, an innovative power amplifier, temperature controls, and reduced emissions
RRU installations close to the antenna system improves system coverage and reduce feeder costs .
