How to strengthen the beeline modem at home. Amplification with a repeater. Creations of "folk artists"

Hello dear users! Today, namely in the century information development technologies always want to have access to high-speed Internet anywhere in the world. But there are places where the mobile Internet does not catch well, and the cable is problematic or very expensive to stretch. For example, if in a country house or in the country you want to do high-speed connection To fully use the Internet, you should install, for example, an antenna, which is an addition to the modem.

With proper installation and subsequent configuration, you will receive an Internet connection that will not be inferior in speed to a wired analogue. You can purchase an antenna in specialized store or online market. In today's issue, we will look at how you can amplify the signal of a 3G and 4G modem with your own hands, for example, in the country or it can be private house outside the city, where, respectively, the signal for the 3g modem barely only picks up the signal itself.

At my home, I had to put in a lot of effort to provide a good internet connection. Therefore, in this article I will share with you some tips and tell you in more detail how to amplify the signal of a 3g modem, and you will also learn how to install, configure and test such an antenna and how the signal of a 3G and 4G modem is amplified in general.

How to strengthen the signal of a 3G modem?

So, two months ago, my wife and I bought a wonderful private house, which is located on the shores of a beautiful Ural lake with a beautiful scenic area. There is naturally clean mountain air and, moreover, it is located far from the bustle of the city, in general, all the amenities for a comfortable life and simple relaxation, which we dreamed of.

However, due to the remoteness from the metropolis, it was almost impossible to use the Internet at first. The reason for this can be called the absence of the wires themselves for accessing the Internet. After all, the area is just beginning to develop and the laying of wires for the Internet is still only in the project for the developers themselves.

As a result, I purchased a megaphone connection modem with a decent tariff, but wait high speed from such an Internet, one could only dream of. Who has such an Internet, I think they will understand me. It takes too long to load a video or a large page. There were constant connection failures.

In the end, I decided that it was enough for me to burn my nerve cells, it was time to come up with something in terms of amplifying the signal of the 3g modem.

My choice settled on the installation of a special antenna. I chose this option, because there is no need to tinker with it - the device is already ready. I bought, assembled, and installed, and then enjoy a good internet. The HiTE HYBRID antenna I bought is one of the modern models, thanks to which the signal amplification of a 3g and 4g modem gives a tangible result, take my word for it.

The antenna itself is connected via one cable through which data transmission and power supply are carried out. It took me about 10 minutes to connect the device.

In short, I can tell you that the signal amplification of the 3G modem is carried out using MIMO technology, which is aimed at improving the stability and quality of the connection. The manufacturer claims the device has a gain of 2x13dBi for 3G and 2x16dBi for 4G. Another advantage of the antenna is that the HYBRID antenna is compatible with all modern routers. Alternatively, you can connect it directly to your computer or to a modem.

This is how the installation for increasing the speed of the Internet looks like. As you can see, there are few elements here, so the connection will not take much time.

In the end, I can tell you that I got excellent results not only in the speed of connection to global network, but also in the convenience of setting up the device. In general, if you plan to install another antenna to enhance the 4G signal, then I recommend that you familiarize yourself with this material, since these devices work according to the same principle.

All the necessary components are included in the antenna kit, so you don't have to worry about additional tools for installation of the unit.

Future perspective

I made today's instruction in October 2016. Therefore, now the situation is such that all mobile operators are massively switching from the third generation to the 4G Internet. In spite of high demand, 4G coverage areas are not found everywhere. Of course, in large cities you can easily connect to the fourth generation signal, but in the countryside there may not be 4G. As well as in our case.

To enhance the signal of the 3G and 4G modem, you can add that the owners of private houses and summer cottages are faced with a problem when it is necessary to strengthen the 3G signal, since there is no other option yet in their area. They buy antennas-amplifiers for 3G, and after 1-2 years they have to switch to 4G and purchase a new device. The HiTE HYBRID antenna is installed with a future perspective, the installation is capable of amplifying 3G and 4G, and it also automatically selects the best signal. Therefore, it is best to buy universal antennas. Despite the fact that the prices for such installations are higher, you will save in the future.

Strengthening the signal of a 3G and 4G modem with your own hands

Antenna connection and setup

So let's open the box. Here you will see the antenna itself, which is a small box and a neatly folded PoE adapter. Also in the box there are mounts for the device, a power adapter and an Internet cable that you can connect to a modem, router or directly to a computer. The set looks like this:

I will tell you frankly that this is the first time I hold this antenna. I want to note that it has a completely sealed case made of plastic and metal. HiTE HYBRID weighs about 2 kg, as for the dimensions, they are 250x250x75 mm. The housing is provided with moisture-proof connectors, so the ingress of liquid will not damage the unit. The antenna is intended for installation on the roof of a house, on the street or on a special mount right outside the window. Thus, you will achieve maximum 4G signal amplification.

The installation is not afraid of weather changes, it works stably in heat (up to + 50 ° C) and in frost (from -30 ° C). The manufacturer HYBRID claims that the antenna can function at lower temperatures if the power is turned off in cold weather. Of course, I still cannot verify this information. In the kit you will find a secure mount on the bracket.

The set also includes a 30-meter cable. This is ideal for a private home as you can easily stretch it onto the roof. But if you live in a multi-storey building, then you can purchase a 100-meter cable separately. This cable is intended for data transmission and power supply - I was pleased with such a simple solution, because you do not have to suffer with extension cords and various adapters. The HiTE HYBRID kit contains all the necessary components for installation.

Choosing the right SIM card

As you understand, the antenna is also a modem. You can also connect it to another router. HYBRID requires a SIM card that supports 4G at 2500-2700. If you do not have such a card, the antenna will automatically amplify the 3G signal, the frequency will be 1900-2200. I studied various reviews and came to the conclusion that HiTE HYBRYD will work with all Russian operators providing 3G and 4G mobile Internet. I will perform a test with a 4G SIM card from Megafon. Let's see what will come of this and what will be the signal amplification of the 3g modem.

The SIM card must be placed in a special slot (shown in the photo), and then the waterproof cover must be screwed on securely. It closes hermetically here, so you don't have to worry about the health of your SIM card.

The instructions indicate the address that we need to open on a laptop or personal computer. Here you will see the management interface.

You will also see the connection status and statistics, you don't have to go into this data too much. The main thing is to check the download and upload speed.

So, we are testing the antenna for signal amplification of the 3g modem.

We need to know how to change the speed after installing the antenna. Please visit this site Speedtest.net before starting the installation

Here you can check your current internet connection speed. I compared it with a Megafon modem, the SIM card was the same. The HiTE HYBRYD antenna is intended for open areas, so the test, taking into account the location of our house in an open area, we can say that it meets the specified criteria.

The first location is in the house under the table

First, I checked the antenna in the house itself, namely near the computer system unit to find out how the signal of the 3g modem is amplified if you do not take the antenna outside. I put the antenna on the system unit. As a result, the speed test service showed that the incoming speed is 6.21 Mbit / s, and the outgoing speed is 1.21 Mbit / s. We can say that this is quite a good indicator.

The second location is in the house by the window

Then I brought the antenna to the window and again measured the Internet speed with the service. In this case, the antenna gave an incoming speed of 8.62 Mbit / s, and an outgoing one - 1.05 Mbit / s. If you do not understand what these numbers mean, then I recommend that you familiarize yourself with these articles, here I have already told in detail what these numbers mean:

As you can see, in the second case, the result was much better. The signal amplification of the 3g modem in the second case turned out to be much better than 8.62 Mbit / s. Thus, I can say that in my case, the Internet is working well today,

The third location - On the roof of the house

This time I took the antenna out of the house and fixed it on the roof of the house. As a result, the test showed that the higher from the ground, the higher the Internet speed. The service with which I checked the connection this time gave the following results: incoming speed 11.95 Mbps, outgoing - 0.44 Mbps.

What else can I say in terms of signal amplification of the 3g modem?

In general, I had to wait a long time for the modem to load the site where the speed test is being carried out. As for the antenna, here you can see everything - 11.95 Mbit / s. This is the best indicator that I was able to achieve away from the metropolis.

The screenshots above show that the use of the HiTE HYBRID antenna significantly increases the signal gain of the 3G and 4g modem. Of course, large web pages and HD videos took a long time to load. Nose social media there were no problems.

Concluding today's article, it is worth noting that there are many other ways to amplify the signal of a 3g modem. It can be some kind of personal device, which, by the way, can also amplify the signal by several orders of magnitude, or ready-made devices. Here's an example of the following video:

So if you have been suffering from a low speed of Internet connection for a long time and still don’t know how to strengthen the signal of a 3g modem, then it’s time for you to take action on this matter.

Cellular operators today are actively working on the quality of 3G signal coverage. It has become very convenient to use the Internet, the modem signal is very high within the city. All you need is to get a USB modem for your PC or laptop. However, in many localities it is simply impossible to use this miracle of progress due to weak signal, there are still many so-called "dead zones" on the map. You should not count on good Internet speed in such places: the speed here is surprisingly low or it is completely impossible to "catch" the connection. A 3G and 4G signal booster will help to cope with this problem. How to build it and use it correctly? Let's try to figure it out!

Some settlements still remain without internet

Experienced users went through several options with which you can amplify the modem signal, and chose the most effective ones. This:

purchase of a kit with a 3G or 4G repeater;
construction of a special antenna;
moving the device to the street or closer to the window;
using a reflector.

Rearranging the modem

If a laptop with a 3G or 4G modem is placed on the street or placed on a windowsill, then the signal can be increased by about 15 percent. Making an outdoor modem is not hard, you just need to buy a USB extension cable. The solution is considered not the best, but the least expensive. If we talk about the shortcomings, then these are:

the inability to improve the connection on the phone;
the presence of an extension cord leads to a loss of signal power;
you need to choose one point, it will be inconvenient to move around the house;
the speed does not change much.

Reflector

You can even make such a device for a modem with your own hands. The method is considered very popular, because to create a reflector you do not need to spend a lot of money and study the process for a long time.

The modem signal is capable of amplifying even a colander, which is very convenient if the network is lost, for example, in the country. Alternatively, you can use a tin can, an optical disc, or a regular saucepan. All you need to do is place the modem in the center of your chosen reflector. A homemade "device" will focus the signal on a 3G or 4G modem.

If you decide to use a kitchen pot, you can put the device inside, or you can upgrade the structure: solder a wire to the pot, and then place the equipment exactly in the center. One more detail - the laptop must be nearby, otherwise the signal will weaken while it travels through the cable.

The method requires the user to display some ingenuity and ingenuity. With a little time developing a reflector, you can boost the modem signal on your laptop by 20 percent.

Remembering the cons, we note:

it is not so easy for some users to recreate the design of the reflector;
the product may be too bulky;
the signal is not amplified as desired;
the place where your "base" is located may not be the most convenient.

Making a 3G or 4G antenna

With the instructions, you can do almost any thing with your own hands. Many have heard about the Kharchenko antenna, which can also be utilized to improve the Internet. To make it, you will need an understanding of the operation of the microwave, as well as certain skills.

The tools you will need:

soldering iron;
file;
pliers;
copper tube;
wire (3 mm).

The dimensional accuracy of all components plays a key role here. If you make a mistake in the calculations, you can forget about the effectiveness of the method.

It is interesting that such antennas are also found on sale. With their help, the signal can be amplified up to 20 dB.

It is not possible to amplify the signal very strongly, the implementation is highly complex. In addition to the above tools, you will need an adapter, coaxial wire, bracket, crimper. Such a design can be made only after a thorough study of the issue and the availability of a detailed drawing.

3G and 4G repeater

It's really effective method signal amplification. This type of product reduces the negative effect of radiation, it is compatible with all modems that are connected to a computer via USB. In addition, the repeater works perfectly with the products of all cellular operators. You won't have to disassemble the modem itself, which means that the warranty for this device will remain.

It is possible to amplify the signal with the help of a repeater even if it is not possible to catch 3G at all. Experts recommend trying different locations (you may even need to climb into the attic, but the result will be worth it).

The kit includes several components:

the cable that connects the antenna to the repeater;
internal antenna for communication with subscriber devices;
signal amplifier;
external antenna(needed to communicate with operator stations).

Such a kit allows you to maximize the signal, improve the quality of communication on the phone. In addition, with its help you will be able to provide the whole family with 3G and 4G. Installing the repeater is not difficult and fast enough, the design itself looks very ergonomic.

As you can see, there are several methods that allow you to improve the quality of the 3G and 4G signal with your own hands. However, the most effective kit with a repeater, which can be obtained from a specialized store. The specified device will allow you to forget about problems with the Internet!

3G is technology mobile communications third generation. Through it, you can connect to the Internet, download files and send messages. The 3G network is convenient for its mobility and the ability to connect to the Internet wherever there is coverage. And the connection takes place via a 3G modem, which is inserted into the USB port of a laptop or personal computer.

The coverage area of 3G communication is large enough, but not everywhere it can catch stably. Walls, metal structures, and other obstructions and materials that distort the signal are in the way. There may be no signal at all, or it will be weak, which in any case will affect the transmission speed. Let's take a closer look at how to increase the signal level of a 3G modem.

Let's say right away that the methods listed below are of little efficiency. It is guaranteed to amplify the signal of the 3G modem using the professional equipment: 3g signal amplifier (3G repeater), outdoor and indoor antennas, connecting coaxial cable.

As a result of our tests of the simplest kit in a wooden country house, we were convinced that this is the best option. Judge for yourself, before installing the kit, the connection speed was 0.4 Mbps, and after installation 4.5 Mbps. For a domestic manufacturer, the kit is surprisingly reliable, and detailed instructions eliminated ambiguous interpretations of the order of installation and installation of equipment.

How to strengthen the signal of a 3G modem: options

Improvised means of enhancing communication

The easiest way is to buy an antenna that plugs into the external antenna connector on the modem itself. Thanks to it, the signal will become an order of magnitude higher and better. But not all modems have such a connector, and not everyone will want to spend money when you can make an amplifier yourself from available tools, which will help strengthen a 3G modem.

It is enough to take a copper wire, open the cover of the modem and wind it in several layers around the SIM card. We place the rest of the wire outside the premises on the street, attaching a previously cut beer can to it. Such an improvised antenna will increase the signal by 90%, which will delight any internet surfer.

If you don't feel like hanging beer cans outside the windows, then the second option is more suitable, but it will work worse. To do this, you will have to buy the simplest and cheapest speakers, but, most importantly, they should work. It is enough to plug them in and place them next to the modem. The connection level will jump by 30 percent. But often this is not enough.

If you are using a USB modem cable, you should get rid of it and find another way to connect. Usually the cable is the reason for the instability of data transmission, spontaneous shutdown at the wrong time and - sometimes - rebooting the modem. And if you use a telephone instead of a modem, such phenomena will be frequent.

Programs for strengthening the connection of 3G modem

Modems often run on several different communication protocols. At the same time, they try to choose the most stable one. This often leads to ping spikes and unstable connections. The modem automatically searches for a stable network by jumping from one protocol to another. But not all modes are fast, which means that if the signal, for example, of the EDGE mode seems to be more stable than the fastest HSPA, then the modem will work in EDGE mode. Naturally, the speed will drop and this will entail a large ping, latency and sometimes terrible Internet lags. How then to make the modem work only in HSPA mode?

You need to download the program HSPA Locker 1.3b and find it on the Internet good instruction for her. The essence of the program is that it will reconfigure the modem and make the HSPA mode communication the priority and main.

Sometimes users, trying to increase the reception of a 3G modem, search the Internet for programs to solve the problem. However, most of the programs will be paid, and often all their promises do not really work. These programs, as well as online services, have nothing to do with speeding up the modem. They just compress traffic. You can read about this in our article.

The modem speed also depends on the time of day. Indeed, at different times, the number of network tower users in an area may be different. Since the channel is divided into several users, the speed will also be divided. Consequently, at a time of day when there are fewer users, the connection will be much better. These hours usually fall at night, early morning and midday. In the first two cases, the majority is asleep, and in the second, the majority works and they have no time for the Internet, unless, of course, it’s not a day off. Thus, it is possible to adapt to the clock of maximum speed.

Today, all mobile providers offer to use their Internet traffic within the 3G network. Each mobile operator has its own defined coverage area. It provides a good Internet connection, however, going out of its limits, the signal strength decreases, which affects the speed mobile internet... To avoid such unpleasant moments, it becomes necessary to strengthen the signal of the 3G modem. In this article we will tell you how to amplify the signal of a 3G modem with your own hands effectively and inexpensively.

There are several options for enhancing the operation of the modem at home for different situations.

How to amplify a 3G signal with your own hands using the VEGATEL repeater

The 3G repeater is by far the most effective means of strengthening the mobile Internet. It is believed that the best manufacturer is VEGATEL (domestic).

Using a repeater is possible only if there is at least some signal. The phone must catch at least a small 3G signal, so that it is advisable to use an active amplifier for cellular communication and the Internet for a summer residence. This is the most effective method amplify the signal. It gives maximum results. The user will receive maximum speed provided by the provider. The repeater combines the properties of a mobile network signal power amplifier for communication and the Internet. It is used in country houses, cottages, apartments.

The repeater does not work by itself, but as part of a kit. It is complemented by an internal and external antenna connected by a cable. You can purchase finished system that includes all components. For effective amplification, we recommend a ready-made kit VEGATEL VT-3G-kit... The manufacturer has established itself on the market with the best side based on the price / quality principle. This is a certified Russian equipment.

How to Amplify 3G Modem Signal Using Speakers

Everyone has speakers at home, so the cost of this method is zero. Subscribers who use the Internet through a modem noted an improvement in the quality of the connection by 10-20% when approaching the sound speakers. It seems a little, but at a low level of Internet connection it is noticeable. This will slightly enhance the signal of the 3G modem.

When using this method, the columns respond with clicks and pops.

He can get rid of these annoying sounds if you reset the volume to zero.

Signal amplifier for 3g copper wire modem

Another option is to make your own 3G signal amplifier from copper wire. It takes a little work. The amplifier can be made by constructing a structure of copper wire and a tin can. The copper wire must be connected with one side to the SIM card, making several turns around the open modem. Lead the other end through the window. The other end must be connected to a tin can acting as an amplifier. The bank is heading towards the nearest station of the cellular network. The quality of the Internet connection will increase to 90%.

Before you start making a cellular amplifier, you can try to solve the issue in another way. You can enhance the signal reception of 3g modem. Device mobile phone provides for the transition from 3g mode to 2g mode with a sufficiently low power of the Internet connection. To prevent this from happening, you need to go to the phone's settings and select the correct mode of operation for the Internet connection. It is important that the connection field is not selected "automatically", otherwise, at the slightest signal weakening, the connection will change the mode and it will become impossible to use the network.

By default, the mode is selected in the way described above, but you need to remember that each phone model has its own characteristics and may have its own program for connecting to the network.

Below is a simple and effective method to self-improve the signal strength of the modem. The method is based on the principle of operation of a satellite dish. At the same time, there is no need to solve tasks that are beyond the power of a non-professional and to redo the device.
To make this not a tricky device, you need an object capable of performing the functions of a reflector. This property is inherent in bowls, basins, discs and cans.

Plus, you need to purchase a three-meter cable with female-to-male USB connectors. It is required to connect the reflector and the computer. The sequence of work is as follows. A flash drive is mounted in the core of the disk. The easiest way is to tape it with tape. One end of the cord will connect to the USB flash drive, and the other to the cable, for which there are USB connectors. The disc is mounted on the front of the house, on the outside of the wall, or on a pole. It is important to point the USB stick towards the strongest signal reception of the base station. This method improves the quality of the 3G connection, but not very much due to the length of the cable.

The reflective surface acts as an amplifier. The more reflective the surface, the better 3G signal you can expect. You can use any flat cookware made of stainless material except enamel.

Dedicated external signal booster for 3g modem

Mobile operators are striving to expand their coverage and improve the quality of communication so as not to lose customers. But until the coverage is expanded to the required area, temporary solutions to the issue of Internet connection have been invented. For this, a 3g signal amplifier for the Megafon, Beeline, MTS, Tele2 modem is being produced. The purchase of such a device solves the issue of signal power amplification and independent search for a solution.

The device is an antenna connected to a 3G modem.

The model must be selected individually based on the characteristics of the radiation pattern and the gain. Amplifier antenna industrial production also installs towards the base mobile operator, which is in the vicinity. The amplifier cord is short so as not to compromise signal quality.

How to improve the signal quality of a 3g modem using an internal antenna

Another option for an independent way out of the situation is to use additional devices to connect to the internal antenna. Access to the connector on the internal antenna can be a stumbling block. If it is hidden, then not everyone will decide to re-solder the device on their own. If the connector is open, then you can purchase an amplifier or use it as a TV antenna. If the connector is hidden or not provided, then you can use the services of a wizard to resolve this issue. When remaking the body of the internal antenna, it is important to understand that it will not be possible to remake it back, just as it will not work to operate the modem only with an internal antenna.

A lot of people decide to independently resolve the issue of improving the quality of the Internet connection using improvised means. Typically, the quality of the coverage increases by 30-40%, depending on the length of the cable.

It is important to look into the settings to make sure that the phone is picking up a signal in 3g mode. It is possible to independently resolve the issue of signal strength, the main thing is to make every effort and use all the proposed methods. Then the result will not be long in coming. Each method of strengthening has found its supporters and has a positive result.

How to make an amplifier for an Internet modem with your own hands

The Internet signal in the city is provided by the presence of base stations and a special cable. In this case, the signal is stable and guarantees the speed ordered by the tariff. And what to do outside the city, where there is no fiber-optic cable?

Outside the city, there is no base station and paved fiber-optic cable highways for high-speed Internet. Usually, providers develop a high-speed network where there is a large population of people. And it’s quite expensive, even for large organizations. As they say, it is not economically feasible!

Therefore, ordinary Internet consumers in the summer are tormented with Internet access and speed when they go outside the cable network.

A few years ago, there was no way to connect to the Internet outside the developed infrastructure. Three years ago, with the appearance usb modems, it became possible to use the Internet in country houses and dachas. But the signal is inferior and the speed is the same. There is only one way out: make an amplifier for an Internet modem with your own hands or buy a 3g signal amplifier.

3G network coverage map

Each provider has its own network. For example, in 2012 I bought an MTS modem and suffered the whole season: there was almost no signal at all. I had to urgently go to the city to hand over the work done, not to mention surf the Internet.

The next year, on the advice of friends, I connected to the Internet via Beeline. Of course, I was happy, because compared to MTS, it was gorgeous. But…, only in the afternoon. In the evening, with the increase in the number of Internet consumers, the network hung up.

To choose best provider for your country house, it is necessary to conduct a network analysis of each provider. The 3G coverage map of a particular provider will help you understand this issue.

Type in the search line "MTS network coverage map".

In the address bar you need to write the address and the point you are looking for will be automatically indicated on the map. Now look: is there a network at a given point or not and of what quality.

MTS 3G network coverage map at the desired point

The map shows that there is no MTS signal on my street and two neighboring ones.

Do the same with the cards of other providers: in Izhevsk, apart from MTS, these are Beeline, Tele2, Megafon.

Coverage map of the 3G Beeline network at the desired point

The 3g network coverage map of Beeline shows a good network, but in fact there was no normal signal for the following reasons:

the nearest base stations of Beeline are located on the outskirts of the city
between the last base station and my street a little more than 8 km (less than 10 km), which means that 3g seems to be there, but the modem is constantly losing the 3g network and switches to 2g mode. Such switching usually occurs due to a weak signal level or high load.
3G modems operate at frequencies of 1900-2150MHz. The signal of this frequency range passes well only in the "line of sight". Obstacles in the form of mountains, forests, high-rise buildings are obstacles for signal propagation over long distances. And the map shows that in a straight line between the city and my street there are several decent-sized "bald spots". Most likely, they play some kind of negative role.

As a result of such a search on the 3g network coverage map, I determined that the best option for me, this is Megaphone: a stable network on my street and in the surrounding space for 2-3 kilometers. On the map in the direction of the city all along the 3g network of the same color:

Coverage map 3g Megaphone at the desired point

Although Tele2 has the same indicators:

Coverage map of the 3G Tele2 network at the desired point

The final choice between the two providers can be made by examining the provider's signal strength at the site using a cell phone.

Signal strength of 3G modem

To determine the signal level of a 3g modem, you need to do the following research on the ground:

using a cell phone (the same provider as the modem), determine in your suburban area the places where the signal is maximum. Walk around all the corners of the cottage: behind the house, behind the bathhouse, in the open space ..., everywhere.
if there is an indicator on the laptop, then do the same by walking around the entire site with a laptop
plot indicators on the paper at these points - make a map
choose the most suitable 2-3 points for you and carry out additional studies of the signal level, but already in height: on the 2nd floor, on the roof, using a pole 2-3 m long, etc.
stop your choice in one place

The determination of the signal strength of a 3G modem can also be controlled using programs that not only show the signal strength, but also allow them to be controlled so that the modem itself can choose the desired type of network depending on the reception quality. But, for now, this business seems very difficult to me.

Such research is necessary in order to determine the direction. Nearest base station the provider may be on the wrong side where you previously thought. If there are several of them, then for some reason a good signal does not come from the one you were guided by.

And yet, how to strengthen the signal so that Internet access outside the city is stable and faster ??

In the online store or offline, you can buy special equipment for these purposes: an amplifier for an Internet modem

Signal booster for Connect 2.4 wi-fi modem

The signal amplifier for the modem must be selected taking into account the provider's network you have chosen.

For example, the “Connect 2.4 wi-fi” brand amplifiers are popular:

A set for a 3G / 4G modem is designed to provide stable Internet access via USB modems in areas of unreliable signal reception of GSM (GPRS / EDGE), 3G (HSDPA / HSUPA / WCDMA) and 4G (LTE) networks of any operators, as well as providing wireless connecting computers, laptops, netbooks, tablets, smartphones and other devices using WiFi technology.

There are also various devices such as antennas and offset feeds. But, I want to consider the complete set of this amplifier:

antenna
cable length 1.8 m
wireless router for wifi

In principle, if you don't need Wi-Fi, you can buy an antenna with a 5m cable like RK-50-3-18

After we have clarified the complete set of the purchased amplifier, we will consider the options for homemade designs.

Last season I made a simple 3g modem amplifier with my own hands. I didn't take any measurements, I just asked the guy-seller about the amplifier in the store (I was ready to buy any, if only I had the Internet at the dacha). The guy told me about his method, and I just repeated it:

you need to buy a 3-5m extension cord with male-to-female usb connectors
take a CD and make a mount for a flash drive on it in the middle of the disc
outside the window, from the outside, on the facade, make some kind of fastener for the disk, such as a carnation
hang the disk with the modem from the outside of the window or on the window from the inside of the room (if it is raining or cold), and connect the other cable connector to the laptop

That's the whole design. Indeed, the signal is not badly picked up, compared to what it was.

This small amplifier design works by the length of the cable and the mirrored CD-like surface.

If you increase the area of the amplifier and instead of a CD disc use something of a larger diameter, you can significantly increase the signal reception.

Here I found a self-made 3g modem amplifier design on the Internet, similar to my design, but with a large "antenna" diameter:

take aluminum basin
mark the center of the basin and come up with some kind of fastener for the modem at this point. The modem must point exactly to the center of the basin.
we connect a cable 5 m long or more, if, when examining your site, you determined that you need to raise the amplifier higher
we hang the bowl on the wall of the house in the direction where the signal is picked up to the maximum. Can be fixed on a wooden pole and raised as high as possible above the house
We select the best location for the center of the basin using the "poke method" and fix it completely so that it does not unfold in the wind.

Instead of an aluminum bowl, you can use an aluminum colander:

Homemade modem signal booster from a colander

They say that the signal level rises 3-4 times. I am going to try this design this summer season, because I need high-quality Internet.

Why homemade? Because I already know from my design that this option works. And because they say that a purchased amplifier for an Internet modem does not guarantee quality - "money down the drain", because "our brother is being fooled": a home-made one works, but a purchased one does not. There is no amplifier in it - a simple reflective table-type antenna ( Connect).
