In today's world, many cannot imagine their life without the Internet. A quality mix is what everyone strives for. If you live in a small town or village, you may have encountered the problem of poor internet connection. How to amplify the signal? To do this, you need to create an amplifier (antenna), which is able to improve the quality of communication. First you will need to purchase a 4G signal amplification kit, find the device circuit and select the necessary tools. So you can create the simplest device without the help of a professional. How is 4G signal amplification? Let's look at it.
4G antenna
The antenna is the simplest device that can improve the quality of communication. They are of two types: external and internal.
As a rule, the first type of antenna is installed on the roof of a building or objects with a large coverage area. So you can improve the connection even in those places where before it was almost impossible to do.
The second type of antenna is usually used to amplify a signal inside a room. If the outdoor antenna has transmitted a signal, but the connection is poorly distributed inside the building, then you should install an internal one. If the quality of the Internet connection is rather poor in your area, then the internal antenna will not help you.
DIY 4G signal gain
How to strengthen your internet connection? To do this, we need to purchase special equipment, which in the process will be combined into a single system. The antenna will allow you to achieve a high-quality signal and no longer think about the problems of its loss or poor speed due to poor connection. What does the equipment consist of?
- Repeater (two-way amplifier). It is an intermediate link, it is in it that the signal from the antenna will come.
- External or internal antenna. That is, the frame that will be installed on the roof of the building or indoors.
- Coaxial cable.
- It is also necessary to purchase a cable splitter.
Amplifier Elements
Devices that connect to the network can be divided into several groups. The first group is the active elements. These include devices that operate on the network, namely, the repeater and connectors. The remaining elements (antenna, divider and cable) belong to the second group - passive. 4G signal amplification can be done using various systems. This is calculated individually for each object. It is better to use a system for which it is necessary to use a minimum cable length. So the loss of quality of the Internet connection will be minimal. You should consider this when designing a circuit to amplify the signal.
How does the repeater work?
When creating an antenna to amplify the Internet signal, you need to understand how its individual elements work. A repeater is an important part of an amplifier, it is a kind of repeater. How does he work? As you probably already guessed, it processes the received signals and redirects them in the right direction. If this is an outgoing call, then to the base station tower. In another case, redirects to the user's device.
The 4G signal is amplified by an antenna. You can make a simple amplifier yourself without resorting to the help of professionals. 2 types of antennas should be used. One will receive the signal and send it to the station, and the second is responsible for the distribution of the Internet connection indoors.
Signal Amplifier Fabrication
Using a signal amplifier, you can achieve high-quality Internet connection in any area. Where to use this equipment?
- Amplification of the LTE 4G signal should be made in places where there are interruptions in mobile communications.
- In places where interference is present.
- A good signal allows you to save battery life in your smartphone.
- You can also lower the level of radiation and increase the clarity of messages.
Unfortunately, communication amplifiers are quite expensive. Therefore, many people decide to create such a device on their own. And rightly so, you can do it yourself, so you will increase your skills in working with network elements and save your money. Of course, you have to spend money on some components of the amplifier, but in any case it will be much cheaper. What do we need?
Assembly preparation
To make the simplest amplifier, the following elements are needed:
- A wire about 35 centimeters long.
- A cable, the size of which depends on where the antenna will be installed, is not necessary to take more than 10 meters.
- Connection block
- Fasteners to connect several blocks.
- Plastic.
In the process, it will be necessary to connect various elements, so it is also worth taking electrical tape. After acquiring and purchasing the necessary elements, you can proceed with the assembly of the antenna.
The manufacture of the antenna. Instruction manual
First we need to take the wire. Our task is to make a rhombus out of it. So, bend the wire in the middle 90 degrees. Then we retreat from the center of the bend by about 9 centimeters in both directions and again bend it 90 degrees. After such manipulations, we get a rhombus, which we actually achieved.
Next, you need to bend the ends inside our rhombus and connect the connecting block. It is necessary to perform this so that in the future we can make the connection. Next, you need to make one cut in the polymer pipe and, on the contrary, drill a hole.
So, the antenna assembly is finished, now it needs to be connected. We take a coaxial cable and we clear one end of the insulation. How to connect the antenna to the cable? The external and internal conductor must be connected to the contacts of the connection block. So, the cable should be a continuation of the external antenna.
At the last stage, you need to install the antenna on the roof or attach to the nearest pillar. Of course, you need to choose the right direction so that it is directed towards the station of your service provider. At the end, you must connect the end of the cable to a plate made of plastic. It remains only to test your creation.
That's all. If you followed the instructions, then the antenna for amplification of 3G, 4G signal should live up to your expectations. Communication will increase by several divisions.
Where to install the repeater?
On the manufacture of the antenna, the problems do not end there. It still needs to be connected correctly so that all work does not go to nothing. Proper installation also plays an important role in improving signal quality. It is necessary that the antenna is directed to the station of the mobile operator. You also need to put it in the chosen place and try the Internet connection to make sure the network quality. Only after a complete study of your area and testing the quality of the network can you begin installation.
It should also be remembered that the amplifier should be installed at a distance of 1-2 meters (not less) from the battery or other heating systems.
After mounting the antenna, you can begin to lay the cable. Before repeater testing, all connections must be checked. Make sure they are in integrity and cleanliness. Do not turn on the power if the repeater is not connected to the antenna so that it does not fail. In case you need to disconnect the cable, first turn off the power to the repeater.
Temperature mode
Keep your antenna in the correct temperature mode. As a rule, the minimum value at which such a system can operate is -40 degrees, and the maximum is +50 degrees. It is important to note that the repeater itself needs to be installed only indoors, since negative temperatures adversely affect it.
It is advisable to consult a professional before installing such a system. This is because your system may emit some interference that affects the operation of nearby cellular stations.
How to set up a repeater?
4G internet signal strength will be high quality if you make a good setup of your equipment. So you can get a stable and high signal level. How to carry out commissioning?
The first step is to check the integrity of all connections. The high-frequency wire connects to the repeater and antenna, all these connections must be carefully examined. In case there are power surges, a line filter should be used.
It is also necessary to adjust the gain, this will be the last step. It needs to be configured within 20 dB. This setting can be done manually or automatically.
In the first case, use the potentiometer knob and adjust the location of the antenna. To use automatic mode, you must configure this on the repeater itself. So you can get the maximum signal strength.
