feet System)
1 Introduction
1.1 Overview
AROTA-VQ100K is a quad-band OTA repeater for Verizon Wireless to offer in-building
coverage up to 100K sq. ft. The system provides the digital filter technology enabling the
customer to have a flexible sub-band frequency selection.
The repeater system is designed for modular architecture with rack mountable structure so
that the customer can equip the particular radio module(s) based upon the market demand.
The system supports the following frequency bands and OTA technologies:
700Mhz for LTE,
850MHz for CDMA CELLULAR,
1900Mhz for CDMA PCS .
Each band can be supported by simply plugging in individual modules

2.2 Installation
The installation procedures are described in this section. Please carefully follow the
instructions below when installing the repeater unit.
Check the rack and shelf location
1. Prepare a 19 inch standard rack.
2. Choose a location considering air flowing inside the shelf. (An inner Fan is making air
blowing downward from top to bottom)
3. Install the shelf securing 1U~2U free space for stability and effective heat dissipation
system on the device.

Figure 4 Space Consideration for Shelf Installation
Installing a guide in the rack
1. Check the rack whether a guide bar is already installed to support the weight of the
shelf.
2. If there is not, Use guide bar from the package and install it in the rack as shown in
Figure 5.
Figure 5 Rack Guide Bar Installation

Moving and installing the Repeater Shelf
1. A two-person team should carry the shelf for safety.
2. Put the shelf on the bracket of 19” rack and push it into the end of the rack to mount.
3. Fasten both sides of the shelf with screws in the rack.
Figure 6 Moving and Installing the Repeater
Module Installation
1. Inspect the shelf to ensure the shelf is securely mounted in the rack.
2. Ensure FEU unit is located at the leftmost slot and mount other modules to the shelf..
3. Insert OMU unit into the top horizontal slot first and then, tighten up 2 captive screw
on the both sides.
4. Before inserting modules, compare all names of modules printed on the bottom of
OMU unit with each name that is also printed on every front side of unit. Then,
secure the modules by fastening the screws..

3 Powering Up System
When the normal operation conditions such as cable connections, shelf installation,
input power level, communication with NOC are met, power up the system following the
procedures below.
SW ON
1. Make sure all switches are on OFF position.
2. Locate switches for each modules as shown below..
- MAIN S/W : Bottom of Front FEU Card.
- HPA S/Ws : Bottom of each HPA’s.
3. Turn ON MAIN switch as in figure .①

5. Make sure to turn OFF the switch when removing HPA card from the shelf..
15
Verifying ALARM LED
When the system is operating normally
after power-up, the LED’s should be all
GREEN. After verifying the LED’s are all
green, the next steps can be followed. If
any of the LED’s does display GREEN,
please refer to Chapter 7, Troubleshooting
and Recovery
.

5.3.1.2 MUX(Multiplexer)
MUX filters out the out of band signals. For the uplink, MUX filters out signals from HPA
to antenna so that the system would transmit any RF to other bands. For downlink, it
suppresses out of band signals other than air-coupled signals from the donor base stations.
The main function of Multiplexer and interface diagram between Arrester and
Coupler are as below.
63
Figure 47 MUX

7 Troubleshooting
7.1 General
Power supply out of range
Cause : Faulty Main Power Supply
Remedy : Check Input AC power. If AC Power is ok, replace PSU.
Field replaceable Module fail
Cause : Issues with XCVR or HPA
Remedy : Check which band is having trouble from GUI.
Turn off HPA Power Switch and Replace the HPA.
Replace XCVR if alarm persists after HPA replacement.
7.2 Downlink
Donor Power too high/low
Cause : Input Power level to donor antenna is too high.
Remedy : Check input power level to donor and thresholds for alarm for proper
threshold setting.
Check all connectors to/from donor antenna.
Check donor base-station is operating normally.
Low Isolation
Cause : Low Isolation between Donor Antenna and Service Antenna
Remedy : Reseat XCVR and HPA. Make sure captive panel screw is well tightened.
Check for unintended changes in donor or coverage antenna.
Adjust Antennas for good isolation between Donor and Service Ant.
Synthesizer Failure
Cause : Faulty Frequency Synthesizer.
Remedy : Check Sysnthesizer from which band is issuing the alarm.
Replace the XCVR.
If alarms are on for all XCVR, replace the shelf.
Hardware Failure
Cause : Faulty PSU or Alarm Monitoring unit
Remedy : Replace Shelf
79
Software Failure
Cause : Software Download Failure
Remedy : SW Reboot
Download Software again.
Replace the shelf.
Spurious emissions out of spec
Cause : Spurious emissions exceed FCC limit
Remedy : Check for any failure for each band.
Repleace HPA for the band in alarm
Replace shelf if HPA replacement does not remove the alarm.
Interferer power exceeded
Cause : Interference level is too high.
Remedy : Confirm interference by connecting spectrum analyzer to monitoing port of
FEU. Identify and remove interference source.
7.3 Uplink
Oscillation Detected
Cause : Low Isolation between Donor Antenna and Service Antenna
Remedy : Reseat XCVR and HPA. Make sure captive panel screw is well tightened.
Check for unintended changes in donor or coverage antenna.
Adjust Antennas for good isolation between Donor and Service Ant.
Power at coverage port too high
Cause : Input power to coverage antenna is too high Oscillation detected
Remedy : From GUI, check if Uplink Input Power Upper Threshold value is set at a
proper level.
Consider re-locating coverage antenna.
Please refer to troubleshooting guide for Oscillation Dectected.
Synthesizer Failure
Cause : Faulty Frequency Synthesizer.
Remedy : Check Sysnthesizer from which band is issuing the alarm.
Replace the XCVR.
If alarms are on for all XCVR, replace the shelf.
Hardware Failure
Cause : Faulty PSU or Alarm Monitoring unit
Remedy : Replace Shelf
80
AROTA-VQ100™ User Manual
Software Failure
Cause : Software Download Failure
Remedy : SW Reboot
Download Software again.
Replace the shelf.
Out of band emissions out of spec
Cause : Out of Band emission level exceeds the specification around service band.
Remedy : From GUI, check which band is at fault.
