High Performance Mobile Broadband Access Network The DBS3900 supports high data rates, while downlink and uplink data rates can reach up to 100 Mbps and 50 Mbps @ 20 MHz per cell respectively. For remote coverage, such as offshore drilling platforms, the DBS3900 can support ultra long-distance coverage up to 100 kilometers. For railways, the DBS3900 supports up to 430 km/h high-speed train coverage.

World’s Leading Professional Broadband Trunking Based on LTE technology, the Huawei DBS3900 supports 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, it maintains outstanding performance for traditional trunking: group call setup time < 300 ms and pre-emptive priority call time < 150 ms. Since professional trunking voice and real-time video are delivered in the same base station in the eLTE solution, Capital Expenditure (CAPEX) costs are reduced compared with traditional trunking and data service solutions.

Multiband for Diversified Frequency ResourcesThe DBS3900 supports multiple frequency bands, including LTE-TDD 400 MHz/1.4 GHz/1.8 GHz/2.3 GHz/2.6 GHz/3.5 GHz/3.7 GHz/5.8 GHz and LTE-FDD 800 MHz, including both licensed and unlicensed frequencies. Wide frequency band availability speeds network deployment and adapts to various frequency policies with higher flexibility.

Huawei promotes an distributed base station DBS3900 for eLTE solution. The DBS3900 fully utilizes Huawei platform

resources and a variety of technologies to meet the challenges of mobile network development. Used for radio access in

an eLTE system and as an enterprise base station the product is installed in diverse scenarios that require precise Base

Transceiver Station (BTS) capabilities. The DBS3900 includes two types of basic modules, a Base Band Unit (BBU) and a

Remote Radio Unit (RRU), which can be flexibly configured to meet different usage requirements. In addition, the

DBS3900 features a small size, low power consumption, flexible installation, and easy site deployment.
