Huawei WD5M18397100 RRU3971 1800MHz Remote Radio Unit for LTE base stations.

The Huawei WD5M18397100 is an RRU3971 (RRUB03-1800) Remote Radio Unit operating in the 1800MHz frequency band. This unit handles radio frequency transmission and reception at the cell site, connecting to the Baseband Unit (BBU) via CPRI fibre links. The RRU3971 is designed for LTE/4G network deployments, providing the RF front-end functionality essential for mobile network coverage.

This Remote Radio Unit is part of Huawei’s distributed base station architecture, where the RRU is mounted close to the antenna at height whilst the BBU remains in a ground-level cabinet or equipment room. This configuration reduces feeder losses and improves network efficiency and coverage quality.

The RRU3971 series represents an earlier generation of Huawei’s radio equipment, having been deployed extensively in 4G network rollouts. Whilst superseded by newer models in current deployments, these units remain relevant for network maintenance, capacity expansion of existing sites, and spare stock requirements.
