Huawei DRRU3158i-fa Distributed Base Station (DRRU3100 series) Remote Radio Unit (RRU)

The Huawei DRRU3158i-fa is a Distributed Remote Radio Unit (DRRU) from Huawei’s DRRU3100 series, an ‘i’ variant of the DRRU3158-fa model designed for indoor and distributed antenna system (DAS) style coverage extension rather than macro tower deployment. As a lower-power radio unit positioned close to a distributed antenna layout, it extends mobile network coverage into buildings and other locations that macro sites cannot efficiently reach, connecting back to the baseband unit (BBU3900/BBU3910) over fibre for conversion between digital baseband signals and RF. The ‘i’ designator in Huawei’s DRRU naming typically distinguishes an indoor-optimised or interface variant within the same base model family, consistent with the sibling DRRU3158-fa and DRRU3158e-fa units also in this range. This unit forms part of Huawei’s wider distributed base station architecture, letting operators fill coverage gaps and add localised capacity. Tech-Star (UK-based, shipped worldwide) supplies this unit tested and ready to deploy.
