1. Installation Flow Chart
This document will provide details on how to successfully install the Juni JR-20 Repeater
system. The flow chart below provides a step by step guide for installing the JR-20 Repeater

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)

10
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.
ÎWhere is the target Donor BTS?
ÎWill the Donor Unit be mounted on a wall or a pole? (99% will be wall mounted)
ÎTry to avoid areas where may possibly hinder the communication between the Donor Unit
and the BTS such as large walls.
ÎThe 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.
ÎTry to position the Coverage Unit at the center of the desired indoor coverage area.
ÎTry to position the Coverage Unit so that it is clearly visible throughout the desired indoor
coverage area.
ÎMake 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.
