2.3 Logical Structure An AAU integrates the antenna and RF unit, and its main functional modules include an antenna unit (AU), radio units (RUs), and a power module. The following figure shows the logical structure of an AAU. Figure 2-3 Logical structure of an AAU
An AAU performs the following functions: l
Receives downlink baseband data from the BBU and sends uplink baseband data to the BBU.
l
On the RX channel, receives RF signals through feeders, down-converts the RF signals into IF signals, amplifies them, and performs analog-to-digital conversion (ADC). On the TX channel, filters signals, performs digital-to-analog conversion (DAC), and upconverts the RF signals to the TX band.

2 AAU Introduction
l
Multiplexes RX and TX signals on the RF channel, which enables these signals to share the same antenna path. It also filters the RX and TX signals.
The following table describes functional modules of an AAU. Table 2-3 Functional modules of an AAU Functional Module
Function
AU
An AU functions as an antenna and a remote electrical tilt (RET). An AU has a built-in remote control unit (RCU) that receives control signals from the base station and drives the stepper motor. The stepper motor drives the adjustable phase shifter in the AU through a gear to adjust downtilts of the AU, thereby achieving the RET function.
RU
An RU is a radio frequency unit, and it performs the following functions: l Receives downlink baseband data from the BBU and sends uplink baseband data to the BBU. l Receives RF signals from the antenna system, down-converts the received signals to IF signals, amplifies the IF signals, and performs ADC. The TX channel filters downlink signals, performs DAC, and up-converts RF signals to the TX band. l Multiplexes RX and TX signals on the RF channel, which enables these signals to share the same antenna path. It also filters the RX and TX signals.
Power module
A power module provides power for the AU and RU.

4.4 CPRI Fiber Optic Cables CPRI fiber optic cables are classified into multimode fiber optic cables and single-mode fiber optic cables. They transmit CPRI signals. A multimode fiber optic cable connects a BBU to an AAU or connects two AAUs. A multimode fiber optic cable connecting a BBU and an AAU is 150 m (492.13 ft) long at most. A single-mode fiber optic cable is made by connecting a single-mode pigtail and a trunk single-mode fiber optic cable through an outdoor distributed module (ODM). A single-mode pigtail is 20 m (65.62 ft) and 70 m (229.66 ft) long at most on the BBU and AAU sides, respectively. NOTE
l An ODM interconnects a single-mode pigtail and a trunk single-mode fiber optic cable. l The trunk single-mode fiber optic cables are provided by the customer and must comply with the ITU-T G.652 standard. l A multimode fiber optic cable and a single-mode fiber optic cable are connected to a multimode optical module and a single-mode optical module, respectively.
