2G 3G 4G 70dB Gain Dual Band Range Extender 850MHz 2100MHz Booster
Dual Band Signal Booster 2G 3G 4G 850 2100MHz 70dB Gain Repeater Amplifier
General
The 850/2100MHz Pico Repeater provides an affordable solution to
solve the indoor signal coverage problems due to signal fading and
attenuation caused by architecture obstacles. And its easy
installation and maintenance can help carrier get fast return.
The repeater is working as a relay between the BTS and mobiles. It
picks up the strongest signal from BTS via the Donor Antenna,
linearly amplifies the signal and then retransmits it via the
Indoor Signal Distribution System to the weak/blind coverage area.
And the mobile signal is also amplified and retransmitted to the
BTS via the opposite direction.

Selling Point
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.

How does it work?
1. RECEIVES SIGNAL
The powerful antenna reaches out to access a good signal, and
delivers it to the booster.
2. BOOSTS SIGNAL
The booster receives the signal, amplifies it, and serves as a
relay between your phone and the nearest cell tower.
3. BROADCASTS SIGNAL
Your devices get increased cell reception, and calls and data are
fed through the booster back to the network.
Accessories
a. One dual band signal booster;
b. One indoor antenna;
c. One outdoor antenna;
d. 20meter cable and 5meter cable;
e. User manual;
f. Power adapter.
Technique supporting:
1. If still no signal receipt after activated repeater,please check if outdoor antenna point to signal tower or elsewhere have strong signal and check if strength achieve -70dBm.
2. If cannot call out,please adjust the direction of outdoor antenna.
3. If the strength is not steady,please check if outdoor and indoor antennas are too close;please ensure the outdoor antenna and indoor antenna have distance of 20meters at least,with a wall between and not in a same horizontal line.
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.
FAQ:
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.
