简要描述：
BBU 5900（02311VFF）Huawei BBU 5900Buy the Huawei BBU5900, a high-performance distributed baseband unit for the DBS5900 platform, supporting 2G, 3G, 4G, NB-IoT, and 5G NR.Features include multi-RAT concurrent processing, 6× CPRI optical interfaces, −48 V DC power, 2U 19-inch chassis, and modular scalability with UBBP and UMPT boards.Ideal for macro base station deployments, network modernization, and C-RAN/D-RAN architectures.
The Huawei BBU5900 is the baseband processing unit of Huawei’s DBS5900 distributed base station platform, designed to perform multi-standard baseband signal processing, synchronization, and O&M management for macro radio sites.
It connects to remote radio units (RRUs) through CPRI optical interfaces, forming a distributed or centralized-RAN architecture that reduces feeder loss and improves coverage and capacity.
The unit supports 2G, 3G, 4G, NB-IoT, and 5G NR operation through software-defined radio (SDR) capability.
Chassis type: 19-inch rack-mountable, 2U height indoor cabinet.
Platform structure: Modular design supporting main control, baseband, fan, and power boards.
Main Control Unit (UMPT): Models include UMPTe2, UMPTe3, UMPTg2, UMPTg3.
Baseband Processing Units (UBBP): Models include UBBPe4, UBBPg1a, UBBPg2 (different generations and computing capacities).
Typical Configuration: 1–2 main control boards and 2–6 baseband boards per BBU.
Other modules: FANf fan module, UPEUe power module, UEIUb environment module, optional USCUb board.
