1. Technical Description Huawei RRU5905 02311PRD
The Huawei RRU5905 02311PRD WD5M185909GB is an outdoor, high-density, multi-mode Remote Radio Unit (RRU) engineered to drive high-capacity cellular macro deployment within the 1800 MHz (3GPP FDD Band 3) spectrum grid. Fully integrated into Huawei’s SingleRAN network framework, this compact radio element connects directly to a host centralized Baseband Unit (such as the BBU3900, BBU3910, or BBU5900 architectures) via high-speed optical CPRI/eCPRI paths to deliver robust macro-tier coverage.
Utilizing advanced Software-Defined Radio (SDR) technology, the unit dynamically splits and allocates its hardware processing resources across different cellular standards via pure software profiles. It drives an efficient 2 Transmit and 2 Receive (2T2R) RF signal scheme, producing a total combined power envelope of 160 Watts (2 x 80W). This hardware flexibility allows a single physical chassis to host concurrent configurations of legacy GSM voice channels, FDD LTE mobile broadband carriers, and narrow-band IoT (NB-IoT) pipelines over a shared power pool. Encased in an uncooled blade-style enclosure with passive convection cooling, it mounts easily onto cell tower masts to survive harsh environmental shifts.

7. Huawei RRU5905 02311PRD CPRI Port Multi-Mode Bandwidth Splitting Rule
The most critical engineering parameter that must be included in here is the CPRI Port Multi-Mode Bandwidth Splitting Rule.
The Huawei RRU5905 02311PRD features twin CPRI interfaces capped at 9.8 Gbps. Because this module shares a capped physical envelope across its multi-mode SDR core, field provisioning teams cannot run maximum carriers for all protocols simultaneously. If a network engineering team tries to provision the maximum carrier load of 8 GSM TRXs concurrently alongside a wide 20 MHz LTE carrier, the digital IQ data streaming across the fiber will overflow the 9.8 Gbps CPRI link line, triggering a bit-error rate shutdown. Explicitly state that when deploying in co-existence mode, engineers must use CPRI topology compression software layers or split the traffic paths evenly across both input CPRI ports to maintain link stability.
