2. Introduction
Page 12 M0139AJH User’s Manual for MR418
2.Introduction
2.1.Purpose
The MR418 is 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 MR418 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, amplifies and re-transmits it into the required
dark spot. In the uplink path the repeater picks up the signals from a mobile and re-
transmits it to the BTS.
2.2.The MR418 Repeater
The MR418 repeater is a cost effective solution for enhancing indoor coverage for
400 MHz TETRA and Tetrapol applications. The MR418 gives designers a simple
tool to solve their small area 400 MHz TETRA and Tetrapol coverage and
performance issues.
Especially public safety services demand reliable coverage even in indoor areas. By
increasing the signal level the MR418 improves voice quality and allows high data
rate connectivity.
A web-based GUI (Graphical User Interface) simplifies to commission and configure
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.
Auto Gain functionality enables automatic gain adjustment in order to maximize the
performance in changing RF environments; however, gain may be set manually if
desired. An alarm interface with LED’s and display indicates the status of the
equipment locally. Moreover the status and alarms of the MR418 can be queried in
the web-based GUI.
Optionally, a GSM modem is offered for monitoring the MR418 via SMS. I.e. a SMS
is sent to the common Andrew OMC or to a standard SMS receiver (even a mobile
phone) and any settings of the MR418 can be changed by a SMS launched from the
OMC or mobile. A heartbeat SMS notifies whether the system is in operation.
Moreover, the MR418 can be connected to LAN.

Connect the antenna cables to the antenna connectors and the antennas.
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.

Align the donor antenna towards the BTS. The MR418 provides antenna
alignment assistance. Therefore, press the “Reset and installation assistance”
switch (see chapter 3.2 Design and Connectors) for at least four seconds after (!)
the boot process has been finished (i.e. red ALC LED is blinking for four
seconds). This will set the gain to max. value and disable Auto Gain for about four
minutes. The status LED will be blinking red/green. Align the donor antenna
towards the BTS tower to reach the highest RSSI level possible. Check the RSSI
level at the display (see chapter 7 Alarming and Supervision). After four minutes,
the gain and Auto Gain are adjusted to the same values prior to the activation of

4.3.1. External-Alarm Inputs
figure 4-3 External-alarm connector, inputs
Two external-alarm inputs are provided to monitor the status of external devices.
The external alarms are locally indicated via the web-based GUI or the display. The
alarms can be forwarded to A.I.M.O.S. or to an SMS receiver via modem.
Opto-coupled inputs monitor external devices providing 0 to 5 Vdc. Depending on the
logic of the alarm (active low / active high) an external alarm is generated at low or
high level. In case an external device shall be captured via an alarm-relay contact,
5 V and GND need to be linked by a wire jumper to the corresponding PINs.
