Amplification of the 4G signal in-house

In today's world, many do not imagine their lives without the Internet. A quality connection is what everyone aspires to. If you live in a small city or in a village, then you may have experienced a problem with a poor Internet connection. How to strengthen the signal? To do this, you need to create an amplifier (antenna), which can improve the quality of communication. First, you will need to purchase a 4G signal amplification kit, find the device layout and find the necessary tools. So you can create a simple device without the help of a professional. How does the 4G signal gain? Let's look at this.

Antenna for amplification of 4G signal

Antenna is the simplest device that allows to improve the quality of communication. They are of two kinds: external and internal.

As a rule, the first kind of antennas is installed on the roof of a building or objects with a large area of coverage. So you can improve the connection even in places where it was previously impossible to do so.

The second kind of antennas is usually used to amplify the signal inside any room. If the outdoor antenna has transmitted a signal, but the connection is poorly distributed inside the building, then the internal antenna should be installed. If the quality of Internet connection is quite bad in your area, then the internal antenna will not help you.

4G Signal Strength

How to strengthen the Internet connection? For this we need to purchase special equipment, which in the process will unite into a single system. The antenna will allow to achieve a qualitative signal and no longer to remember the problems of its loss or weak speed due to a poor connection. What does the equipment consist of?

1. Repeater (two-way amplifier). It is an intermediate link, it will receive a signal from the antenna.
2. External or internal antenna. That is, the frame that will be installed on the roof of the building or indoors.
3. Coaxial cable.
4. It is also necessary to purchase a splitter for the wire.

Elements of the amplifier

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) are referred to the second group - passive. The amplification of the 4G signal can be done by means of various systems. This is calculated for each object individually. It is better to use such a system, for which it is necessary to use a cable of the minimum length. So the loss of quality of the Internet connection will be minimal. You must take this into account when designing a circuit for signal amplification.

How does the repeater work?

When creating an antenna to amplify the signal of the Internet, you need to understand how its individual elements work. The repeater is an important part of the amplifier, it is a kind of repeater. How does he work? As you probably already guessed, he processes the incoming signals and redirects them in the right direction. If this is an outgoing call, then the tower of the base station. In another case, it redirects to the user's device.

The amplification of the 4G signal occurs via an antenna. A simple amplifier can be made by yourself, without resorting to the help of professionals. Use 2 types of antennas. One will receive a signal and send it to the station, and the second will be responsible for distributing the Internet connection inside the premises.

Production of a signal amplifier

Using a signal amplifier, you can achieve a quality Internet connection in any location. Where should this equipment be used?

• Enhancement of LTE 4G signal should be made in places where there are interruptions with mobile communication.
• In places where there is interference.
• A good signal allows you to save the battery life in your smartphone.
• Also, you can reduce the radiation level and improve the clarity of messages.

Unfortunately, communication amplifiers are quite expensive. Therefore, many people decide to create such a device on their own. And rightly, you can do it yourself, so you will improve skills in working with network elements and save your money. Of course, you will have to spend on some components of the amplifier, but this in any case will be much cheaper. What do we need?

Preparing for assembly

In order to manufacture the simplest amplifier, the following elements are necessary:

1. The wire is about 35 centimeters long.
2. The cable, the size of which is curled from where the antenna will be installed, is not necessary to take more than 10 meters.
3. Connecting block.
4. Fasteners to connect several blocks.
5. Plastic.

In the process of work, it will be necessary to connect different elements, so it is also worth taking electrical tape. After acquiring and purchasing the necessary items, you can start assembling the antenna.

Making an antenna. Instructions

First we need to take the wire. Our task is to make a rhombus out of it. So, bend the wire in the middle by 90 degrees. Then, from the center of the fold, we retreat approximately 9 centimeters in both directions and again bend it by 90 degrees. After such manipulations, we will get a diamond, which is exactly what they were trying to achieve.

Next, you need to bend the ends into our diamond and connect the connecting block. We need to do this so that we can connect in the future. 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. Take the coaxial cable and clean one end from the insulation. How to connect the antenna to the cable? The external and internal conductor must be connected to the terminals of the connecting block. So, the cable should become a continuation of the external antenna.

At the last stage, you need to install the antenna on the roof or attach to the nearest post. Of course, you need to choose the right direction so that it is directed towards the station of your telecom operator. At the end, it is necessary to connect the end of the cable to the plate made of plastic. It remains only to test your creation.

That's all. If you followed the instructions, then the antenna to amplify the 3G, 4G signal should justify your expectations. Communication will increase by several divisions.

Where should I install the repeater?

The antenna does not end with problems. It still needs to be properly connected so that all work does not go to waste. Proper installation also plays an important role in improving signal quality. It is necessary that the antenna be directed to the station of the cellular operator. Also you need to put it on the selected place and try the Internet connection to make sure of the quality of the network. Only after a full survey of your area and testing the quality of the network can you proceed with installation.

Also remember that the amplifier should be installed at a distance of 1-2 meters (not less) from the battery or other heating systems.

After installing the antenna, you can proceed to lay the cable. Before testing the repeater, all connections must be checked. Make sure that 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 conditions

Make sure that your antenna is in the correct temperature mode. As a rule, the minimum value at which such a system can work is -40 degrees, and the maximum - +50 degrees. It is important to note that the repeater itself needs to be installed only indoors, since negative temperatures have a detrimental effect on it.

It is advisable to consult a professional before installing such a system. This is due to the fact that your system may emit some interference that affects the operation of the nearest cellular stations.

How to set up a repeater?

The amplification of the Internet signal 4G will be of high quality if you conduct a good adjustment of your equipment. So you can get a stable and high signal level. How to properly start up and commissioning work?

The first step is to check the integrity of all connections. The high-frequency wire is connected to the repeater and antenna, these all connections must be carefully inspected. In the event that there are voltage surges, a network filter should be used.

It is also necessary to adjust the gain, this will be the last step. It needs to be set within 20 dB. This setting can be done in manual or automatic mode.

In the first case, use the potentiometer knob and adjust the location of the antenna. To use automatic mode, you need to configure this on the repeater itself. So you can get the maximum signal power.
