简要描述：
Baseband UBBPe4（03057155）Buy the Huawei UBBPe4 — a universal baseband processing unit designed for Huawei BBU3900, BBU3910, and BBU5900 systems.Supports UMTS, LTE FDD, and NB-IoT, with 6× CPRI optical ports, 1× QSFP HEI interface, and multi-RAT concurrent processing.Ideal for macro base stations, indoor LampSite networks, and multi-technology RAN deployments.
(For BBU3900 / BBU3910 / BBU5900 Platforms)
The Huawei UBBPe4 is a universal baseband processing board (UBBP) designed for Huawei BBU3900, BBU3910, and BBU5900 systems.
It provides multi-standard baseband processing and communicates with remote radio units (RRUs) via CPRI optical interfaces.
The board supports multi-RAT concurrent operation, enabling technologies such as UMTS, LTE FDD, and NB-IoT to run simultaneously on the same hardware (depending on software license and configuration).
The UBBPe4 front panel provides the following interfaces:
| Interface | Description |
|---|---|
| CPRI0–CPRI5 | 6 × SFP optical ports for connecting RRUs; support bidirectional optical signal transmission. |
| HEI (QSFP) | 1 × High-speed expansion port for inter-board communication and baseband resource sharing. |
| Supported Topologies | Star, chain, ring, and trunk-chain topologies. |
| Supported CPRI Rates | 1.25 / 2.5 / 4.9 / 6.144 / 9.8 / 10.1376 Gbit/s (depending on software version). |
These interface definitions are consistent across all UBBPe-series boards.
Note: Actual capacity depends on system version, software license, and configured RAT combination. The following figures are derived from Huawei’s technical documentation and engineering guidelines.
UMTS: up to 6 cells (2T2R or 2T4R) per board.
Uplink CE: 512
Downlink CE: 768
HSDPA codes: 6×15
HSDPA UEs: up to 384
LTE FDD: up to 6 LTE cells, supporting bandwidths from 1.4 MHz to 20 MHz.
UMTS: up to 12 cells
LTE FDD: up to 6 cells
Supports simultaneous operation of UMTS + LTE FDD + NB-IoT, depending on the software license and capacity allocation.
Multi-Standard Processing: Handles 2G/3G/4G/NB-IoT traffic concurrently in the same unit.
Board Interconnection: Multiple UBBP boards can interconnect through the HEI (QSFP) port for capacity expansion.
Flexible Networking: Up to six CPRI ports can connect to macro RRUs or indoor radio heads, supporting star, chain, and ring topologies.
High-Performance Computing: Supports dynamic baseband resource scheduling between multiple sectors or RATs.
Macro Base Station (D-RAN / C-RAN): Used within BBU3900 / 5900 systems for LTE, UMTS, or NB-IoT deployments, with 6×CPRI connectivity for multi-sector sites.
Indoor / Enterprise Networks: In LampSite or eLTE configurations, UBBPe4 serves as a compact baseband processing board for up to 6 LTE or 12 UMTS cells.

Platform Compatibility: UBBPe4 works with BBU3900, BBU3910, and BBU5900 systems (DBS platform).
Software Version Dependency: The supported CPRI data rates and maximum concurrent RATs vary between SRAN/eRAN software versions.
License-Limited Capacity: The actual number of cells, carriers, and connected RRUs depends on the project-specific license and configuration.
