The Active Antenna Unit (AAU) is a fundamental element in the radio access network (RAN) of a 5G network. Its primary purpose is to enhance the efficiency and performance of the radio communication between user devices (like smartphones) and the 5G base station. Let's delve into the technical details of the Huawei AAU in the context of 5G:
The 5G Base Station uses a set of antennas that connect with the distributed unit. These antennas can be implemented using a passive or active architecture. These are connected to the Base Station cabinet using feeder cables. The Base Station cabinet includes the transceiver and RF processing functions.
The 5G baseband unit is responsible for NR baseband protocol processing, including the entire user plane (UP) and control plane (CP) protocol processing functions, and provides the backhaul interface (NG interface) with the core network and the interconnection interface between base stations (Xn interface ).
It is also for this reason that in 5G, the RRU and the original passive antenna are integrated into one, forming the latest AAU ( active antenna processing unit ). The antenna is integrated, so the volume and weight of the AAU are larger than that of the RRU, the power consumption is also greatly increased, and the price is much more expensive.
