The transmission distance of a single-mode optical cable at one level (that is, from the BBU to an RRU or from one RRU to another RRU) is 40 km. The RRU supports a maximum of three levels of cascading, which enables the longest distance between RRUs and a BBU to be 100 km. . A base station, also known as an eNodeB (for 4G LTE) or gNodeB (for 5G NR) in Huawei's terminology, is a piece of equipment that facilitates wireless communication between user equipment (UE) like smartphones, tablets, and IoT devices, and the core network of the telecommunications provider. Does. . The DBS5900 has two frequency mode: FDD and TDD, supporting 3GPP standard spectrum like FDD 700M/800M/850MHz, TDD, and other industry spectrum like TDD 400MHz and 1. 8GHz The distributed architecture is adopted to separate the RF unit part of the base station from the baseband unit part, connecting. . 2. 2 Functional Subsystem Describes the common subsystem, signal processing subsystem, and antenna feeder subsystem. In addition, the DBS3900 supports smooth. .
