RRU is mainly used in the construction and maintenance of base stations in the field of mobile communications. Currently, RRU is mainly used in the following aspects:
1. Macro station construction: RRU can be used for macro station construction in mobile networks, with a wide coverage area, which can meet the large-scale coverage of wireless communication systems.
2. Indoor distribution system: RRU can be used in combination with DAS (Distributed Antenna System) to provide better wireless coverage in indoor construction.
3. Progressive network evolution of telecom operators: RRU plays an important role in the network evolution process of telecom operators and can improve the rate and reliability of data transmission.
