3. Safety Instructions
Any personnel involved in an installation, operation or service of the Coiler BR-II Repeater
must understand and obey the following:
1.
Coiler BR-II Repeaters must be used exclusively for its application described in this guide’s
product introduction and nothing else.
2.
For your safety, please be aware of power lines at all times during installation and use.
Please make sure to take appropriate safety measures for protection. Contact with highvoltage power lines can cause serious injury or death.
3. Please handle the equipment with care. Mechanical shock due to the dropping or
mishandling of the repeater can permanently damage sensitive RF components.
4. The BR-II Repeaters are designed for indoor applications and should be kept away from
water and humidity.
5. The primary AC power range for the repeater is AC100-240V. It is possible to damage the
repeater if the primary AC power is outside this range.
6.
Conducted emissions can only be carried out when the DC cable is less than 3m long. Please
operate the repeater with DC power cable included in the package and not cables longer than
3m.
7.
An external lightning protector is recommended when the antenna is installed outdoors.
8.
The operating temperature of this product should be between 0°C ~ 55°C.
9.
Any repeater, including Coiler’s BR-II Band Selective Repeater, will generate radio signals
and thereby give rise to electromagnetic fields that may be hazardous to the health of any
person who is extensively exposed to the signals, and is in the immediate proximity of a
repeater or repeater antennas. Therefore, the minimum distance between the user and/or
any bystander and the radiating structure (antenna) of the transmitter is 50cm.
*Coiler’s BR-II Band Selective Repeater complies with or exceeds EMC safety and RF
requirements, as per 1995/5/EC Directive.

5. Product Introduction
The Coiler BR-II Band Selective Repeater is
designed to improve mobile phone signal
coverage and enhance reception in the indoor
areas where mobile signal is limited or
compromised due to construction structures or
natural obstacles. The BR-II is a perfect choice
for network operators seeking a quick and costeffective coverage solution for medium sized
indoor areas. The BR-II Band Selective
Repeater delivers the most reliable mobile
performance in office and residential areas,
restaurants, shops and VIP rooms, offering a
powerful output of +20dBm and a maximum
gain of 80dB.
Coiler VB Series
The Coiler BR-II Band Selective Repeater is
designed as a bi-directional amplifier that
receives and amplifies signals from one or
more base stations and re-transmits the signals
to one or more mobile phones. The repeater
also receives signals from one or more mobile
phones, amplifies and re-transmits the signals
to the base stations.
The BR-II supports customizable bandwidth and offers an Intelligent Auto Gain Control function,
designed to provide a simple plug and play installation. To enable flexible adoption to various
mobile environments, the BR-II Band Selective Repeater features automatic gain adjustment of
30dB range. The BR-II has the traditional Auto Gain Control (AGC) function that regulates the
output power to within its range. To further ensure network safety, the BR-II is equipped with
Auto Shut Down(ASD), and UP-Link Auto Turn On (ATO). Each of the features was designed
with total network safety.
The BR-II series provides the ability for customers to upgrade their BR-II solution from single to
dual band via embedded coupling port with one easy step. If you are current deploying BR-II900, BR-II-1800, or BR-II-2200 within your network, you may upgrade it to a dual band solution
by simply acquiring the unit of the missing network.
Units with an integrated Remote Control Unit (RCU), which enables advanced remote
management functions via Coiler’s Operation and Maintenance Center (OMC) are available.
Coiler’s BR-II Band Selective Repeater complies with or exceeds ETSI / 3GPP RF
requirements and complies with RoHS and WEEE standards.

installation process. The row of green LED is lit
when the repeater is turned on. Blue LED
shows the Received Signal Strength Indication
(RSSI) level (please refer to chart below for the
range of signal strength of each LED lit). There
are also two sets of red LED. The two red LED
closer to the edge would light up when the
output power is too strong and the gain needs
to be reduced.

6. Intelligent Auto Gain Control
The BR-II Band Selective Repeater represents some of the most innovative technologies from Coiler.
The key technology that defines the BR-II and makes it different from its predecessor is a technology
we call Intelligent Automatic Gain Control (IAGC). There are three sections of technologies working
together to form the complete function of IAGC. The first section provides ease of installation while the
next two sections provide advance safety mechanisms. All three sections are vital components of IAGC.
6.1 Automatic Gain Control
The second section of technology feature in the BR-II is the Automatic Gain Control (AGC) with a
range 20dB. If there is a surge of input power, AGC would keep the output power consistent and not go
beyond the max output power level. If the surge maintains constant till the next RSSI detection cycle,
the AGS would kick in and re-attenuate the gain to relieve the AGC from working. By having AGS and
AGC working hand in hand, AGC would always have room for the largest input power tolerance
possible.
6.2 Auto Shut Down and Auto Turn On
If the input power exceeds AGC range on the DL or UL, this would trigger BR-II’s third section of
technology and activate Auto Shut Down (ASD). This advanced safety mechanism includes a set of
technologies ASD and UL-Link ATO (Auto Turn On). ASD is a stage that temporarily stops the RF
function of BR-II. On the UL it will continuously detect the input power and resume RF function as soon
as the input power reduces to a safe range. For the DL, it will make three attempts to detect the input
power in this temporary stage. If the input power reduces to a safe range for the BR-II to operate, the
ATO feature would power the repeater back on and restore all functions promptly. However, if the input
power remains too great and dangerous for the network, it will then shut down completely. A technician
should look into the situation before powering the BR-II back on.

7. Mounting and Installation
1.
Please install the donor antenna in the previously selected location. Please choose a mount type
for the donor antenna that suits your preferences and the environmental conditions. You may need
to reposition or rotate the donor antenna in order to find the direction providing the strongest
signal strength.
2.
Please mount the repeater in the previously selected location. Use the mounting template to locate the
placement of screws. Please note that BR-II can be installed both vertically and horizontally.
3.
Route the cable between the donor antenna and the repeater unit. Connect the cable to the
connector marked ‘BTS’ on the repeater and the other end to the donor antenna. Ensure that all the
connections are tightly fastened. Ensure that the cable is fastened on the wall or to a cable tray, and
secure the connectors to avoid water decay of the cables.
4.
Please install the service antenna(s) in the previously selected location. Route the cable
between the repeater unit and the service antenna. In the case of multiple service antennas, use
appropriate power splitters to split the signal. Route the cable accordingly. Connect the cable to the
connector marked ‘MS’ on the repeater and the other end to the service antenna.
5.
Connect the power cable of the adaptor to the repeater where it is marked ‘POWER’ and plug the
adaptor into the power plug.
6.
Now the repeater will run its AGC to self-adjust the repeater to optimize its power level and gain. You
can find out more details about AGC in Section 6. The Power LED should now be green, and if any of
the Red LED is illuminated after 90 seconds, please refer to Section 11: Troubleshooting of this
manual.
