Description
1 Overview

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 AAU5639w 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 AAU5639w in 5G NR
TDD and LTE networks, respectively.

The AAU5639w supports 64T64R. 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.

Product Characteristics
Leading Performance

Multiple channels
The AAU5639w uses the massive MIMO technology and supports 64T64R. 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 AAU5639w supports a large bandwidth of 250 MHz and C-band deployment. The
AAU5639w 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 AAU5639w has a bandwidth capability of 250 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 AAU5639w 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 AAU5639w is smaller than that of a common antenna.

Flexible deployment
The integrated design of the AAU5639w 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.
