Carritech offers a wide range of support services for the Huawei DBS family of products. From repair and refurbishment to parts supply and continuous technical assistance, we’ve got you covered.
The eLTE Distributed Base Station (DBS3900) is a versatile solution for radio access within an eLTE system and serves as a base station for enterprise applications. It boasts a range of functionalities needed for a Base Transceiver Station (BTS). The DBS3900 is comprised of two primary module types: the Base Band Unit (BBU) and the Remote Radio Unit (RRU), which can be adapted to various operational needs. The compact design, reduced power consumption, and adaptable installation of the DBS3900 facilitate its easy implementation.
As a high-efficiency mobile broadband access network, the DBS3900 delivers significant data rate capacities, achieving downlink and uplink speeds of up to 100 Mbit/s and 50 Mbit/s @ 20 MHz per cell, respectively. It is capable of extending ultra-long-distance coverage up to 100 kilometres, ideal for isolated locations like offshore drilling sites. Additionally, the DBS3900 is proficient in catering to high-speed train coverage of up to 430 km/h for railway systems.
Positioned as a top-tier professional broadband trunking solution globally, the Huawei DBS3900 leverages LTE technology. It incorporates advanced functionalities such as priority calls, call hold, late entry, dynamic grouping, and fallback mode. The DBS3900 excels in traditional trunking, featuring a group call setup time of less than 300 ms and a pre-emptive priority call time of less than 150 ms. Its ability to integrate voice and real-time video trunking within a single base station significantly reduces capital expenditure (CAPEX) when compared to conventional trunking and data service solutions.
The DBS3900 is equipped to support a variety of frequency bands, including LTE-TDD 400 MHz/1.4 GHz/1.8 GHz/2.3 GHz and LTEFDD 800 MHz. This wide spectrum compatibility simplifies network deployments and enhances the system’s adaptability to diverse frequency regulations, offering greater flexibility.
