Overview

The active antenna unit (AAU) is a new type of RF module following the RFU and RRU. It incorporates the functions of RRUs and conventional antennas and requires less site resources. Figure 1.1 Evolution of Huawei base stations

The AAU5339w is one of Huawei's main products that implement massive MIMO in 5G NR and LTE networks. The following figures show the position of the AAU5339w in 5G NR TDD and LTE networks, respectively.

Figure 1.3 Position of the AAU5339w in the network

The AAU5339w supports 32T32R. Through sharp increase of transmit and receive antenna channels, this product provides greater diversity, array, spatial multiplexing, and interference suppression gains. This helps operators to maximize the use of existing site and spectrum resources, enhance the system performance, and improve wireless network capacity.

2 Product Characteristics

Product Characteristics

Leading Performance 

Multiple channels The AAU5339w uses the massive MIMO technology and supports 32T32R. Massive MIMO features the adoption of massive antenna arrays for joint signal reception and demodulation or transmission, and therefore significantly enhances single-user link performance and multi-user spatial multiplexing capability, and improves system link quality and transmission rates when compared with traditional multiple-antenna technologies. Massive MIMO also enables the system to flexibly adjust beam forms in both the horizontal and vertical planes, significantly enhancing 3D coverage capability.



Large bandwidth The AAU5339w supports a large bandwidth of 200 MHz and C-band deployment. The AAU5339w can work in the C-band. The C-band is a mainstream frequency band and has abundant spectrum resources. Operators can obtain more than 100 MHz bandwidth in the frequency band. The AAU5339w has a bandwidth capability of 200 MHz and supports diverse operators' C-Band spectrum resources. Only one such module can be used to complete the C-band deployment, saving site space and reducing network construction costs.

High Integration 

Light weight and small size The AAU5339w integrates the functions of antennas and RF modules. Its weight and dimensions are far less than those of the traditional RRU+antenna solution.



Small frontal area The frontal area of the AAU5339w is smaller than that of a common antenna.



Flexible deployment The integrated design of the AAU5339w saves the installation space required by the RRU, jumper, and external combiner. This simplifies the antenna installation platform and enables flexible deployment. Its support for 3D beamforming and tilt adjustment reduces requirements on the antenna height and facilitates installation.
