LTE PON Distributed Small Cell

4G PON Base Station is a distributed base station based on PON network, which is mainly composed of two parts: 4G baseband unit (4G BBU) and remote unit (4G pRU). This base station utilizes time-division forward transmission technology to solve the problem of Point-to-Multipoint uplink aggregation transmission between BBU and RU links. The baseband unit is used for processing the physical layer and upper layer protocol stack of the wireless access network air interface, as well as operation and maintenance processing, to achieve air interface communication with terminals and connection with the core network; And the downlink distribution and uplink aggregation of communication data from remote units to achieve extended functionality. The remote unit is responsible for RF transmission and reception, using low-power signal transmission to quickly achieve distributed coverage of 4G signals.
