familiar with all safety notices, installation, operation and maintenance procedures contained
in this manual.
2. Read and obey all the warning labels attached to the unit. Make sure that the warning labels
are kept in a legible condition and replace any missing or damaged labels.
3. Obey all general and regional installation and safety regulations relating to work on high
voltage installations, as well as regulations covering correct use of tools and personal
protective equipment.
4. Keep operating instructions within easy reach and make them available to all users.
5. It is the responsibility of the network provider to implement prevention measures to avoid
health hazards which may be associated to radiation from the antenna(s) connected to the
unit.
6. The antennas of the repeater (integrated and / or external) have to be installed in a way that
the regional and national RF exposure compliance requirements are met.
7. Make sure access is restricted to qualified personnel.
8. Only licence holders for the respective frequency range are allowed to operate this unit.
9. Use this equipment only for the purpose specified by the manufacturer. Do not carry out any
modifications or fit any spare parts which are not sold or recommended by the manufacturer.
This could cause fires, electric shock or other injuries.
10. Before opening the unit, disconnect mains.
11.
ESD precautions must be observed! Before commencing maintenance work, use the
available grounding system to connect ESD protection measures.
12. This unit complies with European standard EN60950.
13. IMPORTANT NOTE: To comply with FCC RF exposure compliance requirements, the
following antenna installation and device operating configurations must be satisfied: A
separation distance of at least 20 cm must be maintained between the antenna of this
device and all persons. RF exposure compliance may need to be addressed at the time of
licensing, as required by the responsible FCC Bureau(s), including antenna co-location
requirements of 1.1307(b)(3). Maximum permissible antenna gain is 12 dBi.
14. Make sure the repeater settings are according to the intended use (see also product
information of the manufacturer) and regulatory requirements are met.
15. Although the repeater is internally protected against overvoltage, it is strongly recommended
to earth the antenna cables close to the antenna connectors of the repeater for protection
against atmospheric discharge.

2. INTRODUCTION
2.1. PURPOSE
The MRx18 miniRepeater a bi-directional amplifier used to enhance signals between a
mobile and a base station in a mobile network. It has been designed to increase signal
strength in small and medium sized areas such as offices, shops, and basements. By
boosting the signal level the MRx18 increases indoor coverage and allows high data
rate connectivity.
If weak signal transmissions occur within the coverage area due to indoor applications,
topological conditions or distance from the transmitter, a repeater is used to extend
transmission range. In the downlink path, the repeater picks up the signals from a donor
antenna of a BTS/ Node B, amplifies and re-transmits it into the required dark spot. In
the uplink path the signal picks up the signals from a mobile/ User Equipment (UE) and
re-transmits it to the BTS/ Node B.
2.2. THE MRx18 miniRepeater
Note: The MRx18/x18(/x18) and MRx18/y18(/y18) is shortly denominated as
MRx18 in the following.
Andrew MRx18 miniRepeater gives designers a simple tool to solve their small area
coverage and performance issues.
The MRx18 is easy to install. Also a web-based GUI simplifies commissioning and
configuring the equipment. The RF link (donor) towards the base station is typically fed
from an outdoor antenna while the coverage area is fed by an indoor antenna. The
opportunity to adjust the passband of repeater helps to cover any specific segment or
frequency band.
Due to modular design, the single-varia version MRx18 may be available as a dual-/
triple-varia segment or a dual-band-varia version in one cabinet. The dual-/ triple-
segment MRx18/x18(/x18) is able to transmit two or three variable segments within one
frequency band. The dual-band MRx18/y18(/y18) supports two frequency bands, while
one variable segment is amplified in one frequency band and up to two variable
segments are dedicated for the other frequency band.
Auto Gain functionality enables automatic gain adjustment in order to maximize the
performance, however gain may be set manually if desired.
An alarm interface with a display and LEDs indicates the status of the equipment locally.
Moreover, the status and alarms of the MRx18 can be queried via the web-based GUI.

4. INSTALLATION AND COMISSIONING
4.1. MECHANICAL INSTALLATION
To mount the MRx18 to a wall, proceed as follows:
1. Fasten the wall-mounting
bracket by means of 2 proper
screws (through the pressed-
in thread nuts) to a wall. (The
screw type depends on the
quality of your wall).

4.2. ELECTRICAL INSTALLATION
Note: The electrical installation has to be performed in accordance with the
safety regulations of the local authorities. Due to safety reasons, the
electrical installation must be performed by qualified personnel only.
The repeater must not be opened.
1. Connect the antenna cables to the antenna connectors and the antennas.
2. Use only the power supply delivered with the unit. Do not modify the power supply
unit (PSU) and cable!
Do not mount the PSU to the ceiling!
Connect the DC connector of the power supply and provide mains to the power
supply. Ensure the DC connector is plugged in correctly as in the following
illustrations.
Plug in the male DC connector by
inserting the lug into the guide at
the DC connector with the arrow-
moulded side on top, see
illustrations.
The DC connector of the cable is
equipped with a locking mechanism.
The system of locking the plug is based
on a “push-pull” mechanism. The
locking sleeve has to be pulled back to
free the connection.

3. Align the donor antenna towards the BTS.
4. Align the coverage antenna.
As the default settings of the repeater are set to Auto Gain enabled, only the
frequencies have to be adjusted. Additionally, the repeater can be customized with a
laptop or PC via Ethernet connector:
5. For local connection, connect the straight CAT 6 patch cable to the Ethernet
connector of the MRx18 and the network connector of a laptop or PC.
Start a browser (e.g. Internet Explorer 7 or higher, or Mozilla Firefox) and enter IP
address of the repeater
6. Enter user name: and password to login
7. Commission the repeater according to the description in the following chapter and
save settings to the repeater.
8. Disconnect CAT 6 patch cable and check LEDs and display of the repeater.

If an incorrect username or password has been entered, the following error / attention
message
"You have entered the wrong password. Please check the correct usage of upper and
lower cases or check the CAPS LOCK key on your console."
appears and prompts to insert your username or password anew. Click key F5 to

If an incorrect username or password has been entered for three times, the interface to
the repeater is locked for 30 minutes.
5.2. STATUS
In the Status page, which is the first tab in the menu bar, actual settings are shown.
The values are referenced to the condition when the status page has been opened.
Furthermore, actual alarms of the MRx18 are listed in this page. No values/ alarms are
captured in case the RF section is switched off (see chapter 5.3.1 Settings - Radio
Frequency).
The severity of the alarms can be changed in the Settings page (see chapter 5.3.2
Settings - Alarms). The latency time of each alarm is 10 seconds, i.e. the repeater has
to be in alarm condition for 10 seconds before an alarm is notified.
