2G 3G Cellular 850MHz 1900MHz Dual Band Booster CDMA PCS Amplifier
2G 3G Dual band Repeater 850 /1900MHz Cellular Signal Booster CDMA PCS Amplifier
The advantages of this GSM LTE amplifier include:
LCD Display :
Even a non-technical person can easily install and use this signal booster. The display shows all important information and prompts: input and output signal strength, installation details, power, AGC (automatic gain control), etc.
Sleep Mode :
In the absence of incoming and outgoing calls and data transmission over the Internet, the LCD amplifier goes into sleep mode. This function helps to save energy.
Automatic Adjustment Of Operation :
GSM+4G LTE amplifier can adjust the system gain and signal level. All this helps to avoid self-excitation of the device. If a problem occurs, the device will turn off automatically.
Compact Size And High-tech Design :
The signal amplifier has a small size, light weight, advanced design and intelligent LCD display. It fits perfectly into any interior.

Product Description
A mobile phone signal repeater provides the ultimate solution in any area where cellular communications can not work well due to leak of signals. The repeater device features easy installation & operation, build-in indoor antenna and no interference.
It could also improve indoor electromagnetism environments, protract cellular battery life and reduce radiation of cellphones. A mobile phone repeater is ideal for house, home, office use.
The repeater makes the signal stronger in places with poor signal coverage such as:
1) Underground areas: basements, parking lots, tunnels;
2) Other places where cellular signal is shielded by metal or concrete walls: offices, supermarkets, cinemas, hotels;
3) Places distant from the BTS like private houses.
FAQ:
1. How Booster/Repeater Works?
Repeaters are designed to fulfill the idea of one and main principle: to fill the areas with the weak or bad signal and to amplify these low signals in order to provide you with the communication suitable for you.
1) The outside antenna receives the signal from the nearest mobile base station.
2) The outside antenna sends the received signal through the coax cable to the installed Repeater.
3) The repeater accepts the low signal and improves it.
4) The improved signal goes to the inside antenna through the connection coax cable.
5) The inside antenna send the improved good signal to your mobile phone.
2. Why the signal strength is too weak on the edge of area?
1) Check the outdoor signal and antenna direction.
2) Check booster is full gain or not.
3) Check all of the connectors are tight.
4) Change the location of outdoor/indoor antenna.
5) Check the cable type is suitable or not.
6) Deploy more indoor antennas.
3. After running booster, why the signals are not stable?
1) Checking the distance between donor antenna and server antenna are too close to each other?
2) Checking the signals from donor antenna whether to be stable or not?
3) Connect the system again if it is incorrect connection.
