How is mobile phone signal repeater GSM/DCS/ 2G/3G/4G WORKING ?
The outside antenna catches the low signal from the mobile base station and delivers it to the cell phone
amplifier through the connection cable (coax).
After the signal is accepted by the phone amplifier, the device amplifies it.
Then this amplified signal goes through the connection cable (coax) to the inside antenna.
And after that, the amplified signal transmits to the cell phone.
Features of mobile phone signal amplifier
A. High-gain linear power amplifier
B . ALC and AGC function technology ,
C. Ultra-low noise receive amplifier
D. There is no interference to the base station ,right after the opening of the original system and the base station without the need to adjust parameters ,
E. Stable and reliable electromagnetic compatibility design .
F. The base station dose not cause an increase in background noise ,but will not lead to a decline in the quality of the base station communications
G. With full-duplex communication mode .
H. dispel the heat effective reasonable ,the structure is pretty ,the volume is suitable .
Signal repeater Installation diagram (very convenient and easy to install)
How should you install repeater (very easy and simple):
Step 1: Use your mobile phone to test signal strength outside house or on roof, -70dbm is the basic requirement (full bar).
Step 2 Install outdoor antenna in that location and keep adjusting, point it to signal tower station, try to get best signal.
Step3: Run outdoor coaxial cable into building in a convenient location to connect with signal repeater.
step 4: Mount your indoor antenna with signal repeater
step5: Power up signal repeater device to check the signal inside, moving outdoor antenna until you get satisfied signal.
Note: Connect outdoor (BTS) port with outdoor antenna, connect indoor ANT(MS) port with indoor antenna, outdoor antenna is mounted at a higher position. Both antennas should be 10 meters far away from each other at least.
Indoor and outdoor antenna must be separated by wall.
