Description

Output Power 20dBm 2G 3G 4G Booster Dual Band 850MHz 2100MHz

Dual Band Cell Phone Signal Amplifier 2G 3G 4G 850MHz 2100MHz 70dB Gain Booster Repeater

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

1. Intelligent to guide the installation with LCD


2. Real time display the signal strength.


3. Automatic dormancy when no user make the calling


4. Automatic alarm when installation mistake and provide the according solution


5. Automatic adjust the system gain to avoid the repeater self-excitation


6. Initiative reminding when the device was damaged.

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.

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.

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.
