2 Introduction
Page 11
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 shortl y 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.

4.1. 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 author ities. Due to safety reasons, the
electrical installation must be perf ormed by qualified personnel onl y.
The repeater must not be opened. The maximum antenna hight have
to be 10 meters above ground.
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.
