—— 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.

Signal Coverage Case Of Eight Bands All-network Booster

April 9, 2022
Latest company case about Signal Coverage Case Of Eight Bands All-network Booster
Time: May.28 2019
Address: Tomorrow club, Jiangmen City, Guangdong Province
Requirements: Calling and data signal coverage of all networks
Tomorrow Club is a newly-decorated bar. The bar is luxuriously decorated and the exterior walls are decorated with steel plates, making the mobile phone signals inside the bar, whether it is China Mobile, China Unicom, or China Telecom communications, the call and Internet signals are very poor, even it’s a very hard to send or receive message for wechat.
The renovation of the bar is completed and the opening is imminent. It is imminent to solve the problem of the three network mobile phone signal inside the bar. Because the interior area of the entire bar lobby is about 500 square meters, 8-band equipment is used for customers, and two ceiling antennas are promoted as a lobby coverage solution.
The advantage of using this solution is: the China Mobile low-frequency call GSM900 and high frequency call DCS1800, China Telecom call CDMA800, and China Unicom 3G call WCDMA2100 are amplified and covered to effectively solve the needs and problems of three-network calls.
At the same time, the 4G Internet access signals FDD-LTE1800M of China Unicom and China Telecom, as well as China mobile 4G Internet frequency bands D, E, and F were automatically locked, which were effectively amplified to solve the needs and problems of these three networks.
Besides, the biggest advantage of this 8-band all-network booster is that no matter when the operator adjusts these base stations, it will not affect the user ’s three-network call and three-network data experience, because all existing frequency bands are all covered.
The designed scheme is shown in the following figure,
Use two LPDA antennas to receive wireless. One is to receive and transmit CDMA800M, GSM900M, DCS1800M and WCDMA2100, and the other antenna is to receive and transmit FDD-LTE 1800M and TDD-LTE1900M / TDD-LTE2300M / TDD-LTE2600M (the three-way signal D, E, and F bands for mobile 4G are automatically selected by the device).
Wiring Construction:
After the completion of the construction, test that the signal strengths of the first channel are shown below:
The first channel has a full output power as around +17dbm.
The signal strengths of the second channel are shown below:
4G FDD-LTE1800M of China Unicom and Telecom has a full output power in second channel: +17dBm.
The mobile 4G channel automatically locks the F-band TDD-LTE1900M with the best signal strength + 17dBm full power output.
In the normal working state of each frequency band of the equipment, the signal strength test of each frequency band in the hall is as follows:
The signal strength of the three major operators, whether it is calling signal or data signal, has reached full bar. In addition, when a lot of people test the calling and data signal at the same time in the bar, the signal strength keeps stable to meet the demands.
Dot test of China Mobile and China Unicom signal was performed, it shows the signal coverage and signal strength are balanced. As shown below,
In case of using 8 bands full-network booster, there is no need to consider the working frequency, because all frequency of signal operators are included. Therefore, when design the construction plan, we only need to consider the coverage area, range and required antenna and the length of cables.
It is best to install two LPDA outdoor antennas in an upside down position, pointing to different directions, so that the six sets of values on the screen of the device all work to the maximum output value.
