WD5M18392900 Huawei Huawei SingleRAN Radio Remote Unit

The Huawei WD5M18392900 is an RRU3929 Remote Radio Unit operating on the 1800MHz frequency band. This unit serves as the radio frequency component in distributed base station architectures, handling signal transmission and reception between the baseband unit and mobile devices within LTE cellular networks.

The RRU3929 is designed for deployment in Huawei’s SingleRAN base station solutions, typically mounted at or near the antenna location on towers, rooftops, or poles. It connects to the Baseband Unit (BBU) via CPRI fibre optic links, enabling efficient fronthaul connectivity while reducing cable losses associated with traditional RF feeder configurations.
