Huawei WD5M21383901 RRU 3839 Remote Radio Unit for 2100MHz LTE/UMTS networks.
The Huawei WD5M21383901 is an RRUB01-2100Z120 Remote Radio Unit (RRU) from the RRU 3839 series. This unit operates on the 2100MHz frequency band and provides radio frequency transmission and reception capabilities for mobile network base stations. The RRU connects to the Baseband Unit (BBU) via fibre optic CPRI interface and is typically pole or tower mounted close to the antenna.
The RRU 3839 series is designed for Huawei’s SingleRAN architecture, supporting LTE and UMTS deployments on the 2100MHz band. With 120W output power capability, this unit is suited for macro cell coverage in urban and suburban environments where 3G/4G capacity and coverage are required.
This is a legacy RRU model from Huawei’s earlier LTE deployment era. While superseded by newer multi-band and Massive MIMO units, the RRU 3839 remains relevant for network maintenance, capacity expansion of existing sites, and replacement of failed units in established deployments.
