—— 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.

Full Netcom Coverage in a six-floor youth hostel apartment

January 1, 2021
Latest company case about Full Netcom Coverage in a six-floor youth hostel apartment
Time: Nov.15 to Nov.20, 2019
Address: FM002 Youth Hostel, Shenzhen City
Requirements: Calling and Data signal amplification of all-networks.
FM002 Youth Hostel and FM148 Youth Hostel belong to the same chain of condominiums company. It’s located in Heshuikou Village, Matian Street, Guangming New District, Shenzhen, and are typical houses in a urban village.
The signal strength on the streets is very good, but because the distance between the building and the building is too close, the signal cannot penetrate well indoors. The phone is offline in the corridors and rooms from 1st floor to 5th floor.
Narrow alleys, close houses, and internally sealed decoration structures, no matter how good the signal status outside the street, enters the interior, it has become a state of offline. In addition to the top 6th floor, which can barely have a mobile phone signal, the 1-5th floor has become a disconnected state from the world.
1. Signal Source Survey
The signal on the top of the building is actually very good, and the 6th floor of the youth hostel does not need to be covered by signals, but 1st floor to 5th floor. The roof has a wide view, and the base station antenna of the operator can be seen not far from the roof.
The signal strength of the three major operators are as follows:
From the above data, it can be seen that the signal source of the three major operators on the roof of the youth hostel are all very good. Taking the source on the top of the building and covering the signal room separately, you can solve the signals problem on the 1-5th floor.
2.Scheme Plan
2.1 Device frequency combo as below
China Mobile calling + internet: 900Mhz + 2600Mhz
China Unicom calling + internet: 2100Mhz + 1800Mhz
China Telecom calling + internet: 800Mhz + 1800Mhz
Therefore, at least a 5-band booster would be selected to meet the demands: 800+900+1800+2100+2600Mhz
2.2 Indoor antenna distribution
Based on client’s requirements and the layout, 4 indoor antennas would be distributed in 1st floor, and 7 indoor antennas on each of 2nd to 5th floor. 32 antennas in total, evenly distributed in the aisle.
Considering that the antenna signal in the aisle needs to cover the room through the wall , the signal strength at the end of each antenna is not fewer than + 5dB. Therefore, two high-power booster with output 27dbm, gain 80dbi would be used. Topology pictures are as follows,
The wiring construction on the floor is shown below:
Due to the preliminary survey and communication of the entire project in place, the project implementation was very smooth and rapid.
4.Project Acceptance
The five frequencies could reach full output power. After plugging in , the entire apartment has achieved full Netcom mobile phone signal coverage, and each room and corner can achieve a good Internet and call experience.
From the output value on the screen, the output power of five frequencies all reach a full +27dbm, which could entirely meet the demands.
Exact test on the signal strength and network speed,
Both the strength of the call signal and the speed of the Internet can achieve high-quality results.
As an apartment-type building mobile phone signal coverage, five-frequency full Netcom high-power equipment is undoubtedly the best equipment selection solution. Its advantages are:
1: Complete frequencies. FDD-1800Mhz is not used to solve all operators’ 4G signal, but to use exact frequency to avoid the situation that some phone could receive 4G signal but some can’t. China Mobile 4G must use the TDD standard frequency band to ensure the compatibility of various base-band chips of Apple mobile phones and Android mobile phones, so as to meet the real needs of customers for 4G signals;
2. High output power. The 27dBm output is undoubtedly better to meet more indoor antenna distribution needs. A single device can drive the output requirements of 12-20 indoor antennas (depending on the field environment);
3. 80dbi high-gain. Even when the outdoor environment signal and the source signal are not good, the output signal can be driven to the optimal output state of + 27dBm, maintaining a stable and high speed call Internet signal.
