Lonrise has the RRU3959 900MHZ in stock, along with a wide range of used and refurbished telecommunications equipment from all OEMs.The RRU3959/RRU3959w has a dual-transmitter and dual-receiver design, which further improves the output power and the carrier capacity. The software version of the RRU3959(900MHz (not including LTE (NB-IoT))/1800MHz) is SRAN10.1, which is compatible with the N-1 and N-2 versions of MBTS, MBSC, and OSS NEs. Therefore, the RRU3959 can be used with products of SRAN8.0, SRAN9.0 and SRAN10.1 versions. All these three versions include the RRU3959 software components. The RRU3959 used in SRAN8.0, SRAN9.0 and SRAN10.1 has no impact on the KPI of products. The RRU3959/RRU3959w is an 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 RRU3959/RRU3959w performs modulation, demodulation, data processing, and combination and division of baseband signals and RF signals. By using the software-defined radio (SDR) technology, the RRU3959 can work in GU, GL, UL, GM, UM, GUM, LN, or GLN mode through software configurations, the RRU3959w can work in GL dual-mode through software configurations.
