Huawei Proprietary and Confidential Copyright © Huawei Technologies Co., Ltd. 1  1 Introduction The RRU3268 is the outdoor remote radio unit which is powered by a power cabinet. It is the radio frequency (RF) module of the distributed eNodeB and is installed close to the antenna. The RRU3268 provides the following functions:  Modulates and demodulates baseband signals and RF signals  Processes data  Amplifies power  Detects standing waves RRU3268 is newly designed to support the 2T2R mode, improving output power and carrier capacity. The RRU3268 is configured with the bias tee (BT). The internal BT couples RF signals and OOK signals and transmits them through the TX/RX port A. The internal BT also supplies power to the tower mounted amplifier (TMA). The software of the RRU3268 is backward compatible with the eNodeB and OSS of the N-1 and N-2 versions, where N indicates the current version number, for example, SRAN10.0/eRAN8.0 in this document. In addition, the software package of the three versions includes the RRU3268 software components. Therefore, the RRU3268 of SRAN8.0/eRAN6.0 can be used for SRAN6.0/eRAN2.1, SRAN7.0/eRAN3.0, SRAN8.0/eRAN6.0, and SRAN9.0/eRAN7.0, without affecting KPIs. 1.1 Appearance Figure 1-1 shows the appearance of the RRU3268.
