Description

Dual Band 850MHz 1900MHz 3G Signal Booster 70dB Cell Phone Repeater

70dB Gain Dual Band Cell Phone Repeater 850 / 1900MHz 2G 3G 4G Signal Booster Amplifier

General


The 850 / 1900MHz 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

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 0-27dB.

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. 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 I install a signal repeater myself?
Absolutely. There is no technical expertise required to install your mobile signal repeater kit. Each kit contains everything needed to improve the mobile coverage in your home/office and includes instructions that will guide you through the simple steps necessary to install your repeater.
