WD5MERUKC30 Huawei Huawei Distributed Base Station Radio Remote Unit

The Huawei WD5MERUKC30 is a Remote Radio Unit (RRU) model RRUB03-1800Z120, also designated as RRU 3959W. This unit operates on the 1800MHz frequency band and is designed for deployment in LTE mobile network infrastructure, handling radio frequency transmission and reception at the antenna site.

This RRU is part of Huawei’s distributed base station architecture, connecting to a Baseband Unit (BBU) via CPRI fibre links. It is typically deployed on towers, rooftops or poles to provide cellular coverage and capacity for 4G LTE networks, with the 120-degree sector antenna configuration indicated by the model suffix.

The RRUB03 series represents an established generation of Huawei radio units that has been widely deployed in mobile operator networks. As operators continue network modernisation programmes, these units remain relevant for maintenance, capacity expansion of existing sites, or cost-effective network builds.
