It is the RRU in our 4G LTE base station product ENB. It processes air interface and antenna data through advanced high-speed, low delay if signal technology to help improve the system capacity of. The base station can be divided into two modules: the RRU for transmitting signals and the BBU for processing signals. Because the base station is divided into two parts to work. RRU and BBU are crucial components in base station construction, enabling a distributed architecture that improves efficiency and reliability. The Nokia 475000A (AHPMDB) an AirScale Tri-Band Radio Remote Unit (RRU) for cellular base stations, supporting bands 8 (900 MHz), 20 (800 MHz), and 28 (700 MHz). It has an IP65 ingress protection rating, a weight of 31 kg, and supports both OBSAI and CPRI optical interfaces.
