Important Safety Precautions
The JL20 unit is powered by 12VDC. Only personnel who have received
relevant training from Juni are authorised to open any part or section of the
JL20. To prevent electrical shock when installing or maintaining the equipment,
ensure the supply of VDC (and/or VAC) is removed by switching off the
power from the power source before accessing any section of the equipment.
Only when the Repeater is fully installed and all cable connections are made
should the power be turned on. Ensure all installation items are complete
before turning on the Repeater.
on.
Ensure the total input power to the Repeater is within the range -75dBm ~ -
30dBm. Input powers outside this range may affect Repeater performance.
Ensure frequencies are configured correctly. Incorrect frequency settings can
severely affect Repeater performance.
When installing the Repeater, ensure the heat-sink section of the Repeater is
not exposed to direct sunlight. Where possible, have the heat-sink section of
the Repeater facing a northerly directi
Always observe the warning labels and markings present on the equipment. If
unsure, contact Juni America on [phone] for advice.
The JL20 can weigh up to 5kg. Ensure the correct procedures are used in
moving or lifting the equipment to avoid injury.

1 | INTRODUCTION
1. Introduction
Juni offers a full turn-key solution for LTE Indoor RF repeater. This includes customer service
which is supported by Juni call center ([phone]) and installation service. It is designed
to support SOHO and large office coverage area.
It offers quick install by providing everything needed for installation including system, donor and
coverage antennas, required cables, and installation hardware.
Designed for “Plug and Play” installation, the JL20 provides improvements to call quality and
data speed by eliminating problems such as weak and unstable receive and transmit signals in
areas where base station signals cannot penetrate – such as indoor areas, underground parking
stations and subway tunnels.
The JL20 will receive RF signals from a LTE Base Station, amplify this signal then transmit this
amplified signal to the desired coverage area. The maximum output power of the JL20 is rated at
20dBm for both the downlink and uplink paths.
The JL20 also includes a combination of AGC, ALC, and Shutdown/Recovery control circuitry
that ensure superior performance, providing consistent service in areas requiring enhanced
coverage.
The JL20 is also compatible with the Juni Web GUI software platform to allow remote access to
the LMT (Local Maintenance Terminal), providing simple, yet comprehensive monitoring and
control of the Repeater.
With the Juni Web GUI solution, the user can monitor and control the Repeater site using only a
web browser anywhere there is an internet connection. Using SNMP communication, the NOC is
also notified of specific alarms.

2. System Description
2.1 Configuration
The basic configuration of the JL20 is to receive and amplify the base station signal, then re-
transmit this amplified signal to provide coverage for the desired area as shown in the figure
below.
[Figure 1] JL20 Repeater Configuration
As can be seen from figure 1, the JL20 includes two antennas, the Donor and Service antennas.
The Donor Antenna receives and transmits signals from/to the Base Station while the Service
Antenna transmits and receives signals to and from the Mobile Station. The Mobile Station may
include handsets, mobile phones, wireless modems and other CPE (Customer Premises
Equipment).
In addition to the basic Repeater configuration shown above, the JL20 may be used for other
applications such as In-building coverage, tunnel coverage and any other applications that
require coverage enhancements for a small area.

2.2 Applications
The JL20 is capable of providing solutions for Indoor and SOHO applications. This section
outlines the most typical application scenario suitable for the JL20 Repeater system.

Because the service antennas are located inside the building, it is often necessary to allow
for aesthetic installations. Small cone type omni antennas are included in the package for
use in setting up coverage.

2.3 General Appearance of the JL20 Repeater
The JL20 Repeater is housed inside a one-body cabinet designed to maximize strength and
heat dissipation. The cabinet is rated at IP43 and is suitable for indoor use.
The design of the cabinet allows for wall mounting of the Repeater via the use of mounting
brackets (supplied). Please see section 3 “Installation” for detailed instructions on the
installation of the JL20 Repeater.

2.4 Port & LED Description
The JL20 Repeater has 5 (five) connection ports, 2 (two) LEDs, and 1 (one) DIP switch
located on the bottom of the cabinet.
These ports allow for RF, power and monitoring connections as well as Frequency band
settings.
