82. 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
9 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. 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.
114. 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. Î DIP Switch Functions Fig. 6 DIP Switch General Settings PIN NO.

25 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
261-1) 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
272). 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)
28 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
29signal 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. 1234567891011 1234567891011 Fig. 27 DIP Switch (Uplink Path Activation)
30 8. Status Check 8.1 DU FAULT LED A red LED will turn on if the Repeater is not functioning properly. Each of the LEDs pertains to the status of a specific section of the system as shown below. Fig. 28 DU LED ▶ 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 DU(DONOR UNIT)
31represents a specific section of the system as shown below. Fig. 29 CU LED ▶ POWER – Will indicate GREEN if power is being supplied to the Unit ▶ ALARM – If the RF input level is not within the range set by the installer, or if the system identifies a problem during operation, this LED will indicate RED.

32Appendix 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
33The 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.
