—— 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.

AMR Signal Coverage Case

April 8, 2022
Latest company case about AMR Signal Coverage Case
Time: May.10 to May.11, 2019
Address: Investment Center Mansion,Pingshan District, Shenzhen City
Requirements: AMR signal coverage (AMR: automatic meter reading)
Investment Center Mansion is located in Pingshan Street, Shenzhen, and it’s close to be finished. Power equipment systems were installed on the negative second floor of the five buildings. Since the area is a newly developed building, signal operators' equipment and signals have not been well covered in the area, and there is no signal in the underground parking lot.
The five areas on the negative second floor are power equipment, and the meter reading communication uses China Mobile 4G communication modules, so we need to cover the mobile 4G signals in the five areas in the figure below.
1. Signal Survey
In the area of the first and second floors on the ground floor of the building, the mobile 4G signals detected are all in the 1900Mhz band. The signal RSRP strength is around -90, which can meet the acquisition strength of the source.
2.Device Scheme
Only mobile 4G is needed, and the 1900M band can meet the demand. Therefore, in this customer application scenario, a single mobile 4G F band is used, and the 1900M signal amplifier can be enhanced. This time, a high-power mobile 4G device is used, with a gain of 80dB and a power output of 27dBm.
2、Wiring Construction
Because the power rooms of the five buildings are on the negative second floor, and the distance between each building is very far away, we use a device to transmit signal to each Therefore, a device is used under each building to push multiple ceiling antennas into several rooms for signal coverage.
There are 2-4 power distribution rooms below each building, and the splitters and couplers used in the middle are slightly different. But regardless of the increase or decrease of 1-2 ceiling antennas, the measured output can meet the coverage needs.
50-12 cable is used as outdoor cable, which is introduced from the first and second-floor terraces to the negative second-floor power distribution room through the distribution room well. In the cable tray of the power distribution room, 50-3 feeders, power splitters and couplers are used to match the ceiling antenna of each room.
After the construction is completed, the mobile 4G signals of the five regional power distribution rooms have reached full grid, and the signal strength is high quality, between -60dB to -77dB.
The working value of the equipment is also very good, and it is in the same range as the value calculated by the evaluation.
Exact data tests were performed on 5 room areas, and the entire room was well covered, and the customer passed the acceptance test of the Electricity Bureau on May 13.
For AMR signal coverage in the underground parking lot, the exact frequency and the signal operator are required before the scheme. It is very easy to solve and achieve the effect by measuring the length and loss of the feeder line in the construction and scheme.
