—— CARLOS GREGORIO,United States

Let’s be honest, the quality of my Vodafone mobile signal at home always left much to desire. I just was too lazy to do anything with it. I was absolutely satisfied with the rates and the quality of the signal that I had everywhere and my own house was an exception. However, the coronavirus pandemic changed everything. I started to spend much more

—— Ali , Spain

I bought this booster for my apartment because I was absolutely dissatisfied with the power of GSM and 4G signals that I had there. But now the situation has changed. Thank you for this booster, I finally don’t feel isolated when I stay at home alone.

—— Abdul Mohammed,Germany

I think that’s a very nice solution for those who suffer from problems with voice services and mobile internet and do not want to create any antennas or smth like that themselves. The price is absolutely fair and the quality is amazing.

—— Lena W.,Finland

I was very happy to see the discount that you offered. I know that quite often companies make discounts on goods that are not popular but in this case, I see that the situation is quite opposite. I like that this device is able to improve calls and the internet speed at the same time.

—— Giulia M.,Austria

Thank you! The booster is super cool for a private house. All the rooms are now covered with the improved signal. Now I can’t understand why we haven’t bought it earlier.

—— Nadine Nacht ,Germany

It’s a very cool booster! Thank you, dear team, for your attention to your clients’ needs and the prices that you offer. You are the best, ATNJ

—— Natalia L.,Norway

My 3G and GSM connection used to leave much to desire. But with m new booster I have practically forgotten all these problems. I really like that this device is so compact but so powerful. Thanks, guys, for your amazing work and fast delivery.

—— Goran N. ,Sweden

I can’t understand why I bought this repeater only 2 months ago and not earlier. That’s a very useful device for those who live in a rural area like my family. The improved quality of connection has significantly improved the quality of our life.

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.

 

 

 

Product Description

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.

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.
