—— 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 70dB Mobile Signal Boosters Cellular Repeater Amplifier

 

Mobile Signal Boosters 2G 3G 4G Dual Band 850MHz / 2100MHz Cellular Repeater Amplifier

 

The advantages of this amplifier include:

 

LCD Display.

 

Even a non-technical person can easily install and use this signal booster. The display shows all important information and prompts: input and output signal strength, installation details, power, AGC (automatic gain control), etc.

 

Sleep mode.

 

In the absence of incoming and outgoing calls and data transmission over the Internet, the LCD amplifier goes into sleep mode. This function helps to save energy.

 

Automatic adjustment of operation.

 

The amplifier can adjust the system gain and signal level. All this helps to avoid self-excitation of the device. If a problem occurs, the device will turn off automatically.

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.
