Before
you
get
started
,
you
will
need
to
plan
the
layout
of
your
system
.
This
involves
finding
the
location
with
the
strongest
received
signal
from
the
cellular
tower
,
as
well
as
antenna
,
booster
,
and cable
placement
.
General
installation
steps
:
1
.
Find
the
strongest
received
signal
for
the location
of
the outdoor
antenna
.
2
.
Install the outdoor
antenna
on
the
roof
to
obtain the
strongest
downlink
signal
from
the local cellular
towers
.
It
should also be
as
far
away
as
possible
from
where
you
plan
to
place
the indoor
antenna
(
vertical
separation
is
more
important
than horizontal
separation
)
.
3
.
Install
the indoor
antennas
where
you
want to
improve
the
signal
level
.
6
/

4
.
Mount the booster
,
connect
the cables
from
the outdoor
antenna
and indoor
antenna at
the
designated
ports
,
and
connect
the booster
to
the
AC
supply
(
make
sure
all
the cables
are
connected
before
applying
power
)
.
1.3
How
to
find
the location with the
strongest
received
signal
The outdoor
signal strength
the booster receives
directly
affects
the
efficiency
of
the
indoor
coverage
.
That is
why
it
is
crucially
important
to
install
the
antenna at
a
good
location
and
point
it
properly
towards
a
tower
where
signal
reception
is
the
strongest
.
There
are
many
methods that
can
be used
to
find
the
strongest
signal
from
the
cellular
towers
.
One
is
to
use
the
LCD
display
on
the booster that shows the
downlink
power
output
of
the booster
in
each band
,
the other is
to
use a
mobile
phone
or
mobile
phone
app
to
test
signal strength
,
and the
third
is
to
use
a
commercially
available
signal
strength
meter
.
We
highly
recommend that
you
use
the
LCD
display
on
the booster
as
this
method
is
generally
more
convenient
.
However
,
in
situations
where the desired
carrier
'
s
signal
is much weaker than the other local
signals
,
using
a
mobile
phone
,
app
or
signal
level
meter
can
be
a more
accurate
method
of
homing
in
on
the
best
signal
for
installation
.
•
LCD
Display
Method
Connect
the outdoor
antenna to
the booster
'
s
outdoor port
.
Fix
the outdoor
antenna
on
the
roof of
the
building
and
point
it
to
the
nearest
cell
tower
.
Then
have
a
look
at
the
gain
and
output
power
value
displayed
on
the
amplifier
'
s
LCD
.

The outdoor
antenna
receives the
strongest
signal
when the booster
'
s
downlink
output
power
reaches its
highest
level
in
each
band
.

alarms
(
no

or
red
in
LEDs
)
,
it
means
the
present
location
is
the best
for
ensuring
that the
booster has maximized
performance
.
The maximum downlink
power
for
Industrial
100
K
is
27
dBm
,
and the maximum
7
/

H
/
BOOST
downlink
gain
is
83
dB
.
Note
:
These
showed values
may vary
dynamically
at
times
between
1
-
3
dB
which
is normal due
to
outdoor
signal
conditions
.
When the
ALC
legend
is
flashing
,
it
means
the received
signal
power
is
stronger
than the
system
needs
it
to
be
.
It
is recommended
to
adjust
the outdoor
antenna
orientation until the
ALC
alarm
disappears
.
Or
you
can
leave
it
as
it
is
to
let the
booster
self
-
adjust
automatically
.
However
,
when
the
ALC
flashes
,
and
the
displayed
gain
is
30
dB
less than the
amplifier
'
s
rated
max
gain
value
,
try
to
adjust
the outdoor
antenna to
decrease the received
signal
power
from
the
local
tower
.
Otherwise
it
may
be
necessary
to
install
an
attenuator
on
the
outdoor
antenna
port
to
decrease
the
input
signal
level
from
the local
tower
.
•
Mobile Phone Method
You
can use
a
telephone
to
test
signal strength
on
the
top
of
the
building
.
The
number
of
bars
on
the network
indicator
will
define
approximate
strength
of
the
received
signal
.
Normally
the
roof of
the
building
is the best
place
to
receive the
strongest
signal
.
As shown
on
the
drawing
below
,
you
need
to test
the
signal
in
the
points
from
A
to
E
,
and select the location
with
the best
signal strength
for
outdoor installation
.
It
is recommended
to
use a
mobile
app
that
can
display
in
a
test
mode
the
signal
level
in
dBm units
.
It
is
more
accurate
than
checking
the
signal
bars
.

Note
:
Please
try
to
receive
a
signal
from
cell
towers
that
are
not
overloaded
with
multiple
users
.
This
can
be
estimated
by
the
population
density
in
the
area
served
by
the
tower
.
For
example
,
it
is
recommended
to
avoid
cell
towers
near
supermarkets
,
shopping
malls
,
stadiums
or
any
other
public places
visited
by
many
people
regularly
.
This
will
help
maintain reliable
phone
call connections
and
higher
speed
data services
.
Mark the
strongest
received
signal

the installation location and direction
for
the
outdoor
antenna
.
1.4
Install
Outdoor
Antenna
Install
the outdoor
antenna at
the
location
with
the

is the best
outdoor
antenna
choice
.

Booster
Commissioning
Overview
:
The
booster has
a
smart
startup
system
.
When
you
have
finished
the
booster
system
installation and
power
on
the booster
,
it
will
start
its
initialization
process
to
check the received downlink
signal
from
the cell site and the isolation
status
.
This
an
automatic
process
designed
to
ensure
its
best
performance
.
This
will
take
approximately
3
-
5
seconds
.
After
the booster
starts
up
,
please
check
if
the
coverage
is
good
.
If
it
is
good
,
the
booster
system
installation is
complete
.
If
the
coverage
is
not
adequate
,
please
fully
reread and understand the
LCD
,
LED
indications
,
control buttons and
MGC
function
on
your
booster
,
as
they
will
help
you
identify
and solve
any
potential
issues
.
Check
the downlink
output
power
displayed by
the
LCD
.
It
may vary
dynamically
at
times between
1
-
3
dB
which is normal due
to
outdoor
signal
conditions
.
It
would be
optimum
that the
output
power
reaches its maximum
rated levels
for
the
largest
coverage
;
but
you
can
always
leave
it
set at
lower
levels
if
the
coverage
is
adequate
.
Please bear
in
mind
that
it
is
nearly
impossible
to
achieve

Some
phones
by
different manufactures
will
often
show
widely
different
signal
level
results
.
Also
,
phones
by
the
same
manufacture
can
show
different

if
they
have

.
Because of
very
large
indoor

multipath
effects
moving

only
a

can
result
in
large changes
in

power
is reached
,
but the

is
not

or
the

.
•
Check
whether the indoor
antenna
is
installed
correctly
.
You
may
try
to
move
the
antenna
location
to
improve
coverage
.
•
If
an
indoor
panel
is
used
,
check
if
adjusting
the
pointing
direction
of
the indoor
antenna
makes
any
difference
.
•
Check
whether
it
is
necessary
to
add
more
indoor
antennas
since barriers such
as
walls
will
block the
signal
penetration
.
