The RRU3953/RRU3953w is the outdoor remote radio unit which is powered by a power cabinet. It is the RF module of the distributed base station and is installed close to the antenna. The RRU3953/RRU3953w performs modulation, demodulation, data processing, and combination and division of baseband signals and RF signals. By using the software-defined radio (SDR) technology, the RRU3953/RRU3953w can work in GU, GL, UL, or GUL multi-mode through software configurations. The RRU3953/RRU3953w adopts a dual-transmitter and dual-receiver design, which further improves the output power and the carrier capacity. The software version of the RRU3953/RRU3953w is SRAN10.1, which is compatible with the N-1 and N-2 versions of MBTS, MBSC, and OSS NEs. Therefore, the RRU3953/RRU3953w can be used with products of SRAN8.0, SRAN9.0 and SRAN10.0 versions. All these three versions include the RRU3953/RRU3953w software components. The RRU3953/RRU3953w used in SRAN8.0, SRAN9.0 and SRAN10.0 has no impact on the KPI of products.
