Introduction

The RRU3939 is an outdoor remote radio unit. It is the RF part of a distributed base station, powered by a power cabinet, and can be located near the antenna. The RRU3939 performs modulation, demodulation, data processing, and combination and division of baseband signals and RF signals. With the Software Defined Radio (SDR) technology, the RRU3939 can support the GL dual-mode operation through corresponding software configuration.

The RRU3939 has a dual-transmitter and dual-receiver (2T2R) design, which further improves the output power and the carrier capacity.

The software of the RRU3939 is backward compatible with the MBTS, MBSC, and OSS of the N-1 and N-2 versions, where N indicates the current version number, for example, SRAN8.0 in this document. In addition, the software package of the three versions includes the RRU3939 software components. Therefore, the RRU3939 of SRAN8.0 can be used for SRAN6.0, SRAN7.0, and SRAN8.0, without affecting KPIs.
