WD5M21397100 Huawei Huawei RRU 3971 Series Radio Remote Unit

The Huawei WD5M21397100 is an RRU 3971 (RRUB01-2100Z160) Remote Radio Unit designed for wireless network base station deployments. This unit operates on the 2100MHz frequency band and provides radio frequency transmission and reception capabilities for mobile network infrastructure.

The RRU 3971 is part of Huawei’s distributed base station architecture, where the remote radio unit is installed at the antenna site and connected via fibre optic cable to the baseband unit (BBU). This distributed approach enables more flexible site deployment, reduced feeder losses, and improved network coverage and capacity for LTE and UMTS networks.

This remote radio unit was deployed in 3G/4G mobile network rollouts and capacity expansion projects. As operators continue network modernisation programmes, legacy RRU stock remains valuable for network maintenance, site repairs, and extending the service life of existing Huawei base station installations.
