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 RRU

This describes the exterior of the RRU that features a modular design

2.2 Panels of the RRU

The RRU has a bottom panel, a cabling cavity panel, and an LED panel

2.3 LEDs of the RRU

All the LEDs of the RRU are positioned on the RRU panel, indicating the running status of theRRU

3 RRU Cables

About This Chapter

The RRU cables include the PGND cable, power cable, AISG multi-wire cable, AISG extensioncable, CPRI optical cable, RF jumper, and alarm cable

3.1 RRU Cable List

This describes the RRU cables The cables are the PGND cable, power cable, CPRI optical cable,AISG multi-wire cable, AISG extension cable, antenna jumper, interconnect jumper, and alarmcable

3.2 RRU PGND Cable

The PGND cable ensures the grounding of the RRU

3.3 RRU Power Cable

The RRU uses a shielded -48 V DC power cable The cable feeds external -48 V DC power tothe RRU

3.4 CPRI Optical Fiber

CPRI optical fibers are classified into multi-mode optical fibers and single-mode optical fibers.They transmits CPRI signals

3.5 AISG Multi-Wire Cable for the RRU

The 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

3.6 AISG Extension Cable for the RRU

When the distance between the RRU and the RCU is more than 5 m, an AISG multi-wire cable

is not long enough to connect the RRU and RCU In this case, the AISG extension cable is used

to extend the AISG multi-wire cable for transmitting RS485 signals

3.7 RF Jumper for the RRU

The 1/2-inch RF jumper is used for the RRU It transmits and receives RF signals between theRRU and antenna

3.8 Interconnect Jumper for the RRU

The interconnect jumper for the RRU connects the RX_IN/OUT ports of two RRUs, and

transmits the RF signals between the RRUs in the same cell

3.9 Alarm Cable for the DC RRU
