Huawei MRRU3908(900) RRU3900 Series (MRRU V3) Remote Radio Unit (RRU)

The Huawei MRRU3908(900) is an MRRU3908 Multi-mode Remote Radio Unit configured for the 900MHz frequency band, a distinct band variant from the 1800MHz MRRU3908 also stocked by Tech-Star. Part of the RRU3900 series (MRRU V3 architecture), it forms the radio front-end of a Huawei distributed base station, mounted at the antenna site and connected to a BBU3900 or BBU3910 baseband unit via CPRI fibre. Operating on the 900MHz band, the MRRU3908 supports GSM900 and compatible multi-mode configurations under Huawei’s SingleRAN platform, converting digital baseband signals to RF for transmission and reception at the mast head. Deploying the radio unit at the antenna site rather than routing long feeder cable back to an indoor cabinet reduces signal loss and improves network performance, the central advantage of Huawei’s distributed RRU architecture over legacy integrated base stations. The MRRU3908 has been deployed across numerous GSM network rollouts and remains a common maintenance and capacity-expansion spare for operators running Huawei 900MHz macro sites. Tech-Star (UK-based, shipped worldwide) supplies this unit tested and ready to deploy.
