2.2 Check for signal strength
Before installing the Item#18-850 in your home/office, make sure that you can place calls on
the outside of
your home/office or in the attic or at roof level where you install the Outdoor
Antenna. The Item#18-850 can only
bring cell phone signals into your home/office if cell
phone signals are reaching the outside of your home/office,
your attic or at roof level. T he
best way to find the cellular signal around your home/office is simply to walk around with
your
cell phone ON. You should use a cell phone on the network/band whose signal you are
trying to improve. The
“Signal Strength” meter on your cell phone will tell you where the
signal is strongest. The Cell Phone “Signal
Strength” meter takes up to 6~10 seconds to
update as you move from location to location, so make sure to take a nice
long pause in every
location you test. The place you choose should either be outside, or in the very least by a
window. If you can reliably make and receive calls outside your home/office, then Item#18-
850 can
bring the signal into your home/office. If only one signal bar is displayed on your
cell phone, indoor coverage
will be limited to one small room or area.
Caution
:
Cell Phone Signal bars are approximate and vary for each model of
phone. The number of bars can fluctuate widely, depending on the
exact location
of the phone, position or angle of the phone, weather,
etc. Most cell
phone signal meters update every 6 to 10 seconds. An
increase of only one
bar typically indicates a 4x to 10x signal
increase. The best indicator of coverage area is your ability
to
reliably place and receive
calls.
2.3 Determine the Needed Coverage Area
Identify the location in your home/office where you need signal coverage Item#18-850 can
cover approximately 2000 ft. the type of antennas used will dictate the exact coverage area.
Coverage varies based
on outdoor signal level, building construction, and general installation.
Walls, ceilings or floors
will reduce the coverage area.
2.4 Location of Outdoor Antenna and Indoor Antenna
It is recommended that the Outdoor Antenna and Indoor Antenna have approximately 15
feet of vertical separation. If the antennas are too close together, the LED’s will turn RED
indicating Oscillations. Place the Outdoor Antenna as high as possible
to capture the best
signal.

1) General Installation
Guidelines
The installation location should be within 3m of an AC power
outlet
The location should not be easily accessible; this will help prevent any
changes in performance of the
repeater.
The power adaptor should be fixed harder and tighter in order to
prevent loose connections to the
socket.
The antenna port location should have enough space so that the feeder line
can be connected easily.
Locations where wall’s surface is fragile and can be easily broken should be
avoided
.

Outdoor coaxial antenna cable should be properly ground for lightning
protection.

3.6 Operating the repeater
Basic Concepts: RF Isolation Check
RF isolation is defined by the path loss or attenuation, between the Outdoor and Indoor
antenna. It is important
to ensure that the two antennas are sufficiently separated, such that
the signal transmitted by one antenna is
not received by the other. For optimal performance,
the separation of the two antennas must provide a path loss
of at least 12 dB greater than the
gain of the repeater. Therefore, the Item#18-850 requires at least 57~ 72dB
of attenuation
between the antennas.
In most cases, isolation will be achieved by properly locating the Outdoor and interior
coverage antennas (Indoor antenna), respectively. The optimal location for the Outdoor
antenna is high above the
roof line, and exterior to the building.
The interior coverage antenna (Indoor antenna) should be installed inside, near or below
the ceiling. Following these guidelines should ensure adequate isolation between
antennas.
oNever mount the Outdoor or coverage antenna near a window, where Signal
can easily pass
through the glass
oMount the Outdoor antenna as high as physically possible to the exterior of the
building, maximizing the vertical separation between antennas and pointing away
from the building, toward the
base station site.
oInstall the antennas taking advantage of any existing building structure. Such as
brick walls,
metal roofs, or multiple wall structures to additionally attenuate the
path between
them.
oWhen using directional antennas inside the building to cover corridors and
hallways, point
the interior antenna away from the Outdoor antenna location.
oIn extreme cases, the building configuration may not allow for such
separation and isolation.
If additional isolation is required, coaxial attenuation
may be inserted between the Outdoor
antenna and the repeater, with the
potential compromise to the coverage within the
building
oThe flow of the isolation check functionality for the Item#18-850 is as
follows.

Step 1) Isolation Check
Start
After “POWER ON”, the repeater is checking the status
automatically. T he Isolation
Checking time is a Max. of 10secs and LED’s turn
ON/OFF repeatedly.
Step 2) Internal Parameter
Setup
It will be check the controller and set up initial parameters. Both LEDs green
Step 3) Isolation Value Check between Outdoor and Indoor
antennas.
If in step one the Isolation was found to be insufficient the LEDs will turn RED
indicating oscillations and the internal amplifiers will be turned off, so the current draw
will be reduced.
Step 4) High power input Checking during operation
When the repeater is working, the signal coming into the unit is being constantly
monitored, if the signal is strong the Green LED will start to blink, indicating that the
Signal is strong, but if the signal is excessively high then the LED will turn into Blinking
RED.

4. Maintenance and
T r oubl es hoo t ing
In most cases, problems with the Item#18-850 can be diagnosed using the Repeater Unit
LED
indicators
4.1 Normal Repeater Operation
The Repeater Unit has two LEDs, marked as D1 and D2 respectively, after the power on
self test both the LEDs become GREEN. This indicates normal operation.
If the input signal is strong then the LEDs will start blinking Green. The operation of the
unit will not be affected and will be considered normal. Blinking green LED is only an
indicator that the signal coming into the amplifier is strong.
4.2 Abnormal Repeater Operation and Troubleshooting
When the Repeater is powered ON, it runs a self test program. If there are any
oscillations on the board the LEDs will stay RED and the amplifier section of the repeater
will be turned off to avoid damage to the hardware.
During normal operation the LEDs are either green or Blinking green. If the input to the
repeater is very high the LED will start to Blink RED. This indicates that the signal
coming into the repeater is too high.
In such a case the repeater location should be changed or the cable length between the
antenna and the repeater should be extended in order to decrease the input to the repeater.

**these settings can be modified by rewriting the software in the dual band repeater unit. The thresholds used to trigger the LED response are as per common
knowledge of cell phone and BTS signal strengths. It is assumed that a high BTS signal indicates possibility that the cell phones will directly communicate with the
BTS and hence, a repeater will not be required for that particular location. This will enable the Installer to choose a proper location for the installation of the repeater
and provide optimum Indoor to the customer.
