Andrew's miniRepeater family gives designers a simple tool to
solve their small area coverage and
performance issues.
The MRX03 is a bi-directional amplifierused to enhance signals between a
mobile and a base station.
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 MRX03
increases indoor coverage and allows
high data rate connectivity.
The MRX03 is simple to install. It has
auto-setup functionality and requires
no additional equipment to commission.
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 unit is available in many configurations:
MRX03B, MRX03D, MRX03/X03B, MRX03/X03D.
The "X03" indicates a single band filter selection while the
"X03/X03" defines either two frequency segments or the
configuration of two independent bands. The "B" version of
the repeater is equipped with a internal coverage antenna
while the "D" version of the repeater has a SMA antenna port
that is used to feed an external indoor coverage antenna via
coaxial cable. All units are available
in different bandwidths with field
adjustable center frequencies.
All members of the miniRepeaterfamily can be combined in a single-
box solution. Even supervision, control and
alarming can be integrated. We offer a detailed
information paper showing all possible combina-
tions and technical data. (PA-101046-EN)
The MRX03 will automatically set its gain to maximize
its performance, however gain may be set manually if desired.
The auto-adaptation feature always keeps the output power
at the maximum possible level, even if the RF environment
changes. The MBSX03 has been designed to compensate for
the loss of long RF cables between a BTS antenna and a
MRX03B or a MRX03D. This booster /
splitter can also be used to distribute the
signals up to four independent cable paths.
The miniRepeater family has an alarm
interface with LEDs and dry-contact outputs which enables
local and remote supervision. An optional remote monitor
function provides equipment alarming via GSM SMS. Alarm
SMSs (including heartbeat) can be sent to the common
Andrew Operation and Maintenance Center (OMC) or to
any standard SMS receiver (even a mobile phone).

Repeater Supervision...
A GSM based SMS transmitter can be
attached to every single miniRepeater. Andrewsupplies you with a box including a GSM
modem, SMS generator and power supply
unit. This box is connected via a six wire
interface to the miniRepeater. After configuring
the SMS transmitter (or just leaving the default
values) the miniRepeater has only to be intro-
duced to the OMC (via ID number or phone
number of the SIM card in the modem) and it is
integrated into the supervision network.
Several miniRepeater can be connected to a
three wire party line that represents a wired
OR functionality to the alarms of a group of
miniRepeater. If it is not required to distinguish
between the two alarm types, a single two
wire connection is sufficient.
