What this product is

What this product is

The BBU3910 serves as the centralized hardware chassis of Huawei's SingleRAN architecture. It houses main control and transmission boards (UMPT), baseband processing boards (UBBP), universal power and environment interface units (UPEU/UEIU), and an intelligent fan module (FAN), orchestrating baseband computation, clock synchronization, and internal power bus regulation.

What problem it solves

Eliminates footprint exhaustion, high heat dissipation overhead, and operational complexity inherent in multi-box legacy macro sites by consolidating multi-RAT processing and power conditioning into a compact 19-inch form factor.

Who and where it is for

Macro cellular base stations, indoor distributed antenna systems (DAS), dense urban micro-sites, and mission-critical enterprise private LTE/5G networks.

Core advantages

  • Huawei SingleRAN multi-mode architecture enables seamless integration and evolution across GSM, UMTS, LTE, and 5G NR cellular networks.
  • Modular hot-swappable slot design with UPEU/UEIU regulated DC power distribution significantly reduces site modification costs and power consumption.
  • High-reliability -48VDC wide-range voltage input (-38.4VDC to -57VDC) adapts perfectly to harsh outdoor cabinet and telecom room environments.
  • Integrated 10GE/GE optical/electrical transmission interfaces and high-performance baseband processing units (UBBP) ensure massive data throughput.
