2 RRU Equipment

About This Chapter

The RRU is a remote radio unit.

The RRU has the following functions:

l Receives RF signals from the antenna system, down-converts the signals to IF signals, andthen transmits them to the BBU or the macro NodeB after amplification, analog-to-digitalconversion, digital down-conversion, matched filtering, and Digital Automatic GainControl (DAGC).

l Receives downlink baseband signals from the BBU or the macro NodeB, forwards datareceived from its cascaded RRU, performs filtering and digital-to-analog conversion, andup-converts RF signals to the transmitting frequency band.

l Multiplexes RX and TX signals over RF channels and filters the RX signals and TX signals.This enables the RX signals and TX signals to share the same antenna path.

2.1 Exterior of the RRUThis describes the exterior of the RRU that features a modular design.

2.2 Panels of the RRUThe RRU has a bottom panel, a cabling cavity panel, and an LED panel.

2.3 LEDs of the RRUAll the LEDs of the RRU are positioned on the RRU panel, indicating the running status of theRRU.

3.5 AISG Multi-Wire Cable for the RRUThe AISG multi-wire cable is 5 m long. It is connected to the RRU and Remote Control Unit(RCU) to transfer control signals from the base station to the RET antenna.

NOTE

The RCU is a driving motor used for the phase shifter in the RET antenna. It receives the control commandsfrom the base station and executes the commands to drive the step motor, which drives the phase shifter in theantenna through the gearing to adjust the tilt angle of the antenna.

l When the distance between the RRU and the antenna is within 14 m, one end of the RF jumper is connectedto the ANT port at the bottom of the RRU, and the other end is connected to the antenna.

l When the distance between the RRU and the antenna exceeds 14 m, the RF jumper is connected to the feederprior to the RRU and antenna. If the RF jumper is provided by the customer, the length of the RF jumpershould not exceed 2 m.

The RF jumper has a DIN male connector on one end and a connector made based on fieldrequirements on the other end. Figure 3-11 shows the RF jumper where both ends are DIN maleconnectors.

3.8 Interconnect Jumper for the RRUThe interconnect jumper for the RRU connects the RX_IN/OUT ports of two RRUs, andtransmits the RF signals between the RRUs in the same cell.

ExteriorThe interconnect jumper has a DB2W2 connector on each end. Figure 3-12 shows theinterconnect jumper.

3.9 Alarm Cable for the DC RRUThe alarm cable for the RRU is a shielded straight-through cable. The cable transmits alarmsignals from the external equipment to the DC RRU and monitors the external equipment.

ExteriorThe alarm cable has a DB15 connector at one end and eight cord-end terminals at the other end.Figure 3-13 shows the alarm cable.

4 Auxiliary Devices of the RRU

About This Chapter

The auxiliary devices of the RRU consist of the Outdoor Cable Conversion Box (OCB) and theIndoor Floor installation support (IFS06).

4.1 OCBThe Outdoor Cable Conversion Box (OCB) interconnects cables of different core diameters.The power cables shipped with the RRU cannot support long-distance power transfer. Therefore,when the power supply is far from the equipment, the OCB can be used to connect the powercable of the RRU and a cable with a large core diameter, which can transfer power for a longdistance.

4.2 IFS06The Indoor Floor installation Support (IFS06) is used for installing RRUs indoors.

4.1 OCBThe Outdoor Cable Conversion Box (OCB) interconnects cables of different core diameters.The power cables shipped with the RRU cannot support long-distance power transfer. Therefore,when the power supply is far from the equipment, the OCB can be used to connect the powercable of the RRU and a cable with a large core diameter, which can transfer power for a longdistance.

Application ScenarioThe application scenario of the OCB is shown in Figure 4-1.
