2. Component Verification and Explanation

The first step when installing the repeater is to check that all components are present and that the

parts do not have any visible faults. The figure below illustrates the items included in the Juni JR-

20 Repeater Kit.

Fig. 2 List of all the Components in the System

Fig. 3 Additional Coverage Unit Components

2.1 DONOR UNIT(DU)

The role of the Donor Unit is to communicate with the BTS. It is located outside the building

where service is to be improved. The Donor Unit can be mounted onto a wall or a pole,

depending on the specific installation needs.

Fig. 4 DONOR UNIT(DU)

2.2 COVERAGE UNIT(CU)

The role of the Coverage Unit is to communicate with the mobiles within the building which

needs improved coverage. It is intended for wall mounting.

Fig. 5 Coverage Unit (CU)

3. Preparing for Donor Unit and Coverage Unit Installation

Determining the proper installation location for the Donor and Coverage Units is very important,

since their position will determine the overall performance of the repeater.

The authorized installer should determine where it will be mounted in accordance with the

instructions received by Juni for best reception by the BTS.

When determining the position of the Donor Unit, the following points should be considered.

Î Where is the target Donor BTS?

Î Will the Donor Unit be mounted on a wall or a pole? (99% will be wall mounted)

Î Try to avoid areas where may possibly hinder the communication between the Donor Unit

and the BTS such as large walls.

Î The Donor Unit should not be located any more than 10 feet away from the wall penetration

or window which will allow access to the inside of the building.

When determining the position of the Coverage Unit, the following points should be considered.

Î Try to position the Coverage Unit at the center of the desired indoor coverage area.

Î Try to position the Coverage Unit so that it is clearly visible throughout the desired indoor

coverage area.

Î Make sure that the distance from the Coverage Unit to the power source is less than 20 feet.

4. BAND SETTING

Once the planning of the location and positioning of the Donor and Coverage Units is finalized,

the authorized installer should proceed with installing the Donor and Coverage Units. But first,

the installer should set the appropriate frequency band(s) for the repeater. The figure and table

below show the DIP Switch and the functions for each section. Usually both the PCS and

Cellular bands have to be set up.

After DIP S/W setting, turn power ON/OFF or DIP S/W 12# PIN ON/OFF.

7. Power Connection and Optimization SETTING

1) Once the RF Cable is connected between the Donor Unit and Bias T and the second RF

Cable is connected between the Bias T and the Coverage Unit, the Power Adaptor should be

connected to the Bias T. If the Power Adaptor is connected to Bias T before the RF cable is

connected to either the Donor or Coverage Unit, possible damage could occur to the

equipment. Therefore the installer should be sure to connect the Power Adaptor to the Bias T

after the RF cables are connected to the Donor and Coverage Units.

Fig. 23 Power PORT Connection

1-1) BIAS-T Installation Guide

. The figure below shows a detailed connection of the Power Adaptor and the Bias T. The

Ground cable at the Bias T must be connected before AC power is supplied to the Power

Adaptor.

Fig. 24 POWER INJECTOR Installation Diagram

2). Once power connection has been successfully made (this can be verified by checking the

Alarm LED on the Donor Unit and LED indications on the Coverage Unit, the Donor Unit azimuth

should be positioned so that maximum signal level is being received from the BTS. This can be

monitored via the LEDs which indicate the signal strength reading (RSSI).

(The recommended LED RSSI reading is 3 bars)

Outdoor DU on a Roof (Pole mount) Outdoor DU (Wall mount)

Once the Donor Unit is mounted onto the pole, it is

capable of being rotated 20° in either

direction. The Donor Unit can also be

mounted anywhere around the pole.

Can be rotated 20° in either direction

Fig. 25 DU ANT Tilt Diagram

3) The type of mounting method used will determine how much flexibility the Donor Unit has

to adjust the azimuth.

The diagram below shows how the installer can maneuver the Donor Unit to obtain the highest

signal strength while monitoring the LED indications.

Fig. 26 Verifying Reception Status Diagram

4) Once the positioning and direction of the Donor Unit has been finalized, use the DIP Switch

to activate the UL path.

▶ MANUAL OFF – If the installer decides to turn off the system, this LED will indicate red.

▶ RF – If the output power level exceeds the preset limit or if oscillation is present, the

Repeater will automatically shut down and the RF LED will indicate RED.

▶ PLL – Malfunction of the frequency setting circuitry will cause this LED to indicate RED.

▶ CU – Malfunction of the Coverage Unit will cause this LED to indicate RED.

▶ POWER – If the input RF level is not within the range set by the installer, or if the system

identifies a problem during operation, this LED will indicate RED.

8.2 CU FAULT LED

A red LED will indicate that the equipment is not functioning properly. Each of the LEDs

CU(COVERAGE UNIT)

Appendix A. Product Introduction

A.1 Overview

The Juni JR-20 MPE25K Repeater system is an RF repeater which provides coverage for

indoor locations within a BTS coverage area. The repeater is intended to serve indoor

locations where there is very little or no RF coverage. The system supports both US Cellular

and US PCS bands. Verizon Wireless-authorized installation personnel are able select to

frequency bands of operation via the internal band selection function. The Juni JR-20

MPE25K Repeater is intended to suit indoor environments of up to 25,000 sq.ft. The system

configuration includes a Donor Unit which is typically located outside the building and a

Coverage Unit which is positioned at the approximate center of the indoor space requiring

better coverage. The role of the Donor Unit is to provide the link between the repeater system

and the BTS. The Coverage Unit is intended to communicate with Mobiles located indoors.

An optional second Coverage Unit may be added to the system to enhance indoor coverage.

Fig. 30 System Installation

The diagram below shows the basic system configuration. Once the two supplied RF Cables

are connected from the Bias-T to the Donor Unit and Coverage Unit respectively and the

Power Adaptor is connected to the Bias T with AC Power turned on, the Donor Units and

Coverage Unit(s) will function properly.
