WD5M1RUACI0C Huawei Huawei Distributed Base Station Radio Remote Unit

The Huawei WD5M1RUACI0C is an RRU3829 Remote Radio Unit designed for 2100MHz frequency band operation. This compact radio unit handles RF signal transmission and reception at the cell site, connecting to the baseband unit via fibre optic CPRI interface to deliver wireless coverage for mobile network deployments.

The RRU3829 is part of Huawei’s distributed base station architecture, typically deployed with BBU3900 or BBU3910 baseband units in UMTS (3G) and LTE (4G) network configurations. The 2100MHz variant supports Band 1, one of the most widely deployed frequency bands for 3G/4G services globally.

This is a legacy radio unit from Huawei’s earlier generation of distributed base station equipment. While superseded by newer RRU models in current network rollouts, the RRU3829 remains relevant for network maintenance, capacity expansion of existing sites, and operators maintaining established infrastructure.
