简要描述：
Baseband UBBPg1a（03050BYF）Buy the Huawei UBBPg1a (03050BYF) — a universal baseband processing unit compatible with Huawei BBU3900, BBU3910, and BBU5900 systems.Supports 5G NR, LTE FDD, and NB-IoT, with 6× CPRI optical interfaces and 1× QSFP HEI port for high-speed baseband interconnection.Ideal for macro base station upgrades, C-RAN/D-RAN architectures, and multi-RAT network expansion.
(Compatible with BBU3900 / BBU3910 / BBU5900 Platforms)
The Huawei UBBPg1a is a universal baseband processing unit (UBBP) used in Huawei’s DBS distributed base station platform (BBU3900, BBU3910, BBU5900).
It performs multi-standard baseband signal processing and connects to remote radio units (RRUs) via CPRI optical interfaces.
Compared to earlier UBBPe or UBBPd series, the UBBPg-series (g1/g1a) introduces 5G NR support, while maintaining full compatibility with LTE FDD and NB-IoT.
UMTS capability may be available depending on software version and license configuration.
| Interface | Quantity / Type | Description |
|---|---|---|
| CPRI0–CPRI5 | 6 × SFP optical ports | Front-haul connectivity to RRUs; supports multiple CPRI line rates and topologies (star, chain, dual-star). |
| HEI (High-speed Expansion Interface) | 1 × QSFP | Used for inter-board communication and baseband resource sharing between multiple UBBP boards. |
| Supported CPRI Rates | 1.25 / 2.5 / 4.9 / 6.144 / 9.8 / 10.1376 Gbit/s | Actual supported rates depend on software version. |
| Feature | Specification |
|---|---|
| Supported RATs | 5G NR, LTE FDD, NB-IoT (UMTS optional) |
| Multi-RAT Concurrency | Supports simultaneous LTE + NB-IoT + NR operation |
| L1 Throughput (reference) | DL: 1200 Mbit/s, UL: 600 Mbit/s |
| Signaling (BHCA) | LTE + NB-IoT: 302,000 + 193,000 |
| MIMO Modes | Supports 2×2 and 4×4 configurations |
Note: Final performance (cell count, carrier capacity, UEs, etc.) depends on SRAN/eRAN version, license, and MIMO/bandwidth configuration.
Compatible Systems: Huawei BBU3900 / BBU3910 / BBU5900
Chassis Configuration: Installed together with UMPT (main control), UPEU (power), and FAN modules.
RRU Topology: Supports star, chain, dual-star, or ring configurations via 6× CPRI ports.
Software Compatibility: Operates with Huawei SRAN/eRAN base station software; version-dependent feature set.
Macro Base Station Deployments (D-RAN / C-RAN): Provides baseband resources for LTE, NB-IoT, and 5G NR in large-scale networks.
Network Modernization: Enables smooth upgrade from 4G to 5G using existing BBU infrastructure.
Capacity Expansion: Adds baseband processing power and supports NR introduction without replacing the BBU chassis.
