What is the booster?
Cell phone signal booster (also named repeater, amplifier) is a product designed to solve the mobile phone blind signal. As
the mobile phone signal is transmitted by electromagnetic waves to establish a communications link, however there are a lot
barriers make it is unavailable to get sound signal. When people enter some tall buildings, some places basement malls,
restaurants and parking lot, some places of entertainment such as karaoke sauna and massage, some public place such as
subway, tunnel and etc. where cell phone signals can not reach, now the cell phone signal booster can solve these problems!
The entire range of mobile phone signals can be well used; we all will get great convenience and benefit from sound signal.
Our boosters are the perfect solutions for a wireless improvement in the mobile reception!

Installation of outdoor antenna
The signal strength from the outdoor antenna directly affects the efficiency of the indoor coverage,
so it is very important to choose the outdoor antenna location to get the best signals.
 Select the top of building, the window or the balcony to install the outdoor antenna where
there is with sound signal.
 Testing the signal strength received from outdoor antenna by mobile phone from different
direction, and it shall display full bar signals where the outdoor antenna installed.
 Fix the outdoor antenna after selecting the best position, and adjust slightly its height or angles
in order to get the best signals.
 The phone calls or data transmission shall be smooth and stable by 3 times testing where the
outdoor antenna installed.

Installation of indoor antenna
Omni antenna (Indoor ceiling antenna or whip
antenna), suitable for installing in the center
and radiate all directions.
Directional antenna (Panel antenna) suitable
for the coverage shape is long and narrow, like
corridors, tunnels or elevators, etc. (The
directional antenna is good for isolation from
outdoor antenna)
-8-
Note: Attention on the install of outdoor antenna and indoor antenna
Booster is a two-way signal amplifier, so proper isolation between outdoor antenna and indoor
antenna is necessary in order to avoid self-oscillation. About the definition for self-oscillation, take
MIC and Loudspeaker for example, if it is too close for each other, it could make big noise. And the
minimum distance between outdoor antenna and indoor antenna shall be 5 meters. Again if the two
antennas install in the same level, then the direction of outdoor antenna and indoor antennas shall be
opposite (in this case, the directional antenna will be a good choice). If the isolation can’t be achieved
by the limited distance, the roof of the building or any other barriers can be put between two antennas
to increase isolation.
How to install the connectors to the cable?
Installation of booster
The booster can only be installed indoor, and can not turn on the power of booster until all
accessories is settled correctly!
Booster’s ports description
1) Outdoor port: Connect with the outdoor antenna by cable and connector
2) Indoor port: Connect with the indoor antenna directly or by cable and connector
3) Power: connect with power supply
ST-92B Repeater with AGC Function
What is AGC function? And what is the advantage?
AGC means Auto Gain Control; it means the booster can control the gain by itself according to the
surroundings.
 When there is a sudden strong signal input, the booster can adjust the gain accordingly to protect
the booster module together BTS station, make the strong signal will not affect the BTS after
adjustment.
 When the signal outside is too weak, the booster can adjust the gain to full stage to boost the signal
received at most for end use.
 The AGC repeater is with LED on it, it can directly show the running state of the booster.
