Output Power 27dBm Smart Tri Band Repeater With ALC AGC Function
80dB Gain 850 / AWS / 1900MHz 2G 3G 4G Cell Phone Signal Tri Band Repeater
Selling Point
1. Smart LCD : Show the real-time signal strength.
2. Sleeping Mode : When no user calls, the device works in Sleeping mode, so as to achieve the purpose of energy saving.
3. ALC(Automatic Level Control) : Automatically adjust the output gain down to optimal figure while the output gain is above the optimal figure by the ALC circuit, this can greatly optimize the calling and data transfer quality.
4. AGC (Automatic Gain Control) : When the downlink output signal is too strong or self-oscillated, booster can automatically reduce the gain and reduce the interference signal.
5. MGC (Manual Gain Control) : In order to install the booster conveniently, all frequency band of the booster have the Gain attenuation adjustment function, the adjustment scope is 0-20dB.

Installation Approaches
1. Fix up outdoor antenna reception on housetop and point to signal tower;
2. Connect outdoor antenna to “outdoor” port in repeater nachine through cable;
3. Connect indoor antenna(s) to “indoor” port in repeater machinethrough cable also;
4. Plug power adaptor into AC power socket and finish installation.
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.
1. Are you trading company or manufacturer ? Could I use our own logo and label?
We are factory, with trading service. We provide OEM/OEM service.
2. Can I have a sample order? What is your MOQ?
Yes, we welcome sample order to test and check quality. MOQ is 1
for normal products.
3. Is it easy to set up your items?
Yes. We have a user manual and support technical support 24/7.
4. Does the signal booster work have radiation or not ?
Yes,but just little ,it also can reduce the radiation when you calling ,because it will have more radiation if no signal when you dialing on your phone.So don’t worry and use in house ,it is better for you than not use when no signal in house.
5. Can this mobile signal repeater create a signal where there is
no cell signal before?
The mobile signal repeater cannot produce a signal, only amplify a weak one.
