1 Pre-installation Consideration
Prepare the proper ground prior to installation of the BDA; the ground must be independent from
that for other equipment (Do not use common ground with others). The ground must be
connected with AWG 6 or AWG 8 multi-wired cable. The cord must not be parallel to other
electrical or RF cable. Do not apply the electric power without connecting output port of BDA to
Antenna or Dummy Load. The system will be stabilized in 5 minutes after power is switched on.
Before operation of the BDA, ensure that RF connectors and cables are not damaged and
properly connected.
DO NOT FASTEN OR UNFASTEN THE COAXIAL CABLE CONNECTOR
ON THE BDA WITH UNDER THE UNIT POWERED EQUIPMENT.
EXTREME CARE MUST BE TAKEN TO AVOID ELECTRIC SHOCK.
MAKE SURE THAT POWER SUPPLIER IN BDA UNIT IS TURNED OFF PRIOR
TO CONNECTING THE COAXIAL CABLE TO THE CABLE ENTRY
CONNECTOR ON BDA ENCLOSURE.
DO NOT OPEN THE DOOR OF THE UNIT WHEN IT IS IN OPERATION
WITHOUT PROPER PERMISSION FROM THE AUTHORITIES.
DANGEROUSLY HIGH VOLTAGES APPEAR WITHIN THE EQUIPMENT.
EXTREME CARE MUST BE TAKEN TO AVOID ELECTRIC SHOCK.

1.1 Introduction
The mobile coverage extension solution is used to extend coverage to specific areas
within a building, multiple buildings, or subway. This coverage extension system solution
features useful combination that distributes wireless coverage over RF cable and
antennas, making the best choice for signal quality, flexibility, and overall performance.
The mobile coverage extension product family offers service providers a flexible, low
cost, easy installation to improve customer retention and offer enhanced services to
meet increasing subscriber demands.
1.2 Site Selection
Depending on RF environment and size of space, output power of the BDA and number
of antennas are decided for optimum service. For instance, an OMNI antenna (service)
is connected to a small BDA for a small room, two or three OMNI antennas are con-
nected to a medium BDA, or several antennas are distributed in couple of floors of a
building if a large BDA is installed.
Recommendation to choose installation topology as below;
Figure 1 BDA Solution for in-building
z Less interference from other BTS Cells
z Easy access and maintenance of the equipment
z Avoiding direct sunlight to protect equipment
z Easy access to electrical power
z A shadow and cool environment
BDA Installation and Operating Guide
Version 1.0 7
1.3 Antenna Installation
Recommendation to choose installation location as below;
z Use proper and reliable connectors.
z Ensure that connections of antenna and feeder cable is proper, so that
antenna VSWR is at least 1.38 : 1(equal to 16dB of return loss).
z Ensure that antenna radiation beam pattern is normal before antenna
installation. There are cases that antenna beam pattern is abnormal though
antenna input VSWR is normal and this problem cannot be recognized with an
Analyzing Equipment.
z Secure and water-tight connection between cable and antenna.
z Cables with low loss.
z Elimination of pulling stress or kinks in cable.
z Proper radius of curvature in cable placement.
z Secure proper isolation between link antenna and service antenna.
z There must not be any obstacles to reflect signal from the direction that
antenna is radiating signal.
z Tightly fix link antenna to prevent movement against wind or other external
factors.
z For more information regarding detailed specifications and installation of
antenna, contact the antenna supplier.

1.4 Electrical Power
z Power source must be stable and maintain enough capacity. It must also be
protected against surge and lightning.
100Vac
z A AWG 6 or AWG 8 multi-wired cord must be used for grounding. The cable for
grounding must not be placed paralleled to other cables.
1.5 Initial Check
z Unpacking
Prior to unpacking, check the containers for damage. If any damage or
mis-handling is evident, request that the carriers be present to witness the
unpacking and further inspection.
Carefully open the containers, remove the top layer of shock absorbing
material, and lift the equipment out of its container.
z Mechanical Inspection
Check the equipment for damage. Inspect the housing and panel surfaces
for scratches and dents. Check that all external fasteners are securely in place
and that no obvious attempt has been made to remove any of these.
z Damage
If the equipment is damaged or fails to meet specifications upon receipt,
notify MTI Co., Ltd. immediately.
z Storage
The equipment should be placed in its original container for storage, and
should be stored in a cool, clean and dry environment.

supply and outdoor antenna. Avoid direct sunlight and humidity, and keep it under
where with good ventilation allowance. BDA installation was described following
procedure.
First, Drilling on the wall in proper side.
Second, Insert the BDA mount pilot in hall and Fix the BDA mount as above.
Third, Hang up the BDA.
Forth, Connecting the Antenna cable.

Connection and checking of RF output power
Figure 18 Cable arrangement at the BDA
z Connect coaxial cable to the “SVC ANT” port and the 50Ω coaxial cable
connected to measure the output power from the monitor port(“SVC ANT” port
side) of BDA with a Spectrum Analyzer.
z Connect the AC power cable to the power connector on the bottom panel of
the BDA and then check if ‘Power’ LED on the front of the BDA is green and
‘RUN’ LED is blinking.
z Measure input power with a Spectrum Analyzer at BDA input or GUI and
compare it with the expected level. For instance, suppose input power of the
BDA is -55dBm/Total. Output power of monitor port should be +20dBm/Total.
z Set proper forward gain in the Operating Software. As the forward input
power of the BDA is -55dBm, FWD Gain of BDA must be 75dB to output
+20dBm/Total.
z Enable FWD_HPA. And then check output power of the BDA using Spectrum
Analyzer. Forawrd Output power of the MCU must be less than +20dBm,
where typical output power is +20dBm.

3.3.3 COM Port Set-up
z Prior to control the SDM Center program, vacant communication port, which is not
occupied with other device, should be secured. This can be checked via control
panel of Window OS. Conventionally, every communication devices have to occupy
the unique resource "COM port" of PC even though such a COM port number are
changed according to each PCs. Therefore, if you choose such an occupied COM
port by other devices as the COM port of SDM Center program, you will encounter a
port collision and not be able to run the SDM Center program properly. In order to
run the SDM Center program normally, you should select an available COM port
except COM port occupied by other programs.
