How to amplify a bad cellular signal. How to improve the quality of cellular communication in an apartment. Installing the receiving antenna and repeater

The network coverage of cellular operators is not continuous. And no one will make it continuous - it is economically unprofitable. A certain contribution here is made by the peculiarities of the propagation of radio waves, which is why radio silence zones may arise at certain points. Poor signal reception cellular communication- this problem is relevant for many people, especially for those who live outside the city, far from the nearest base stations... Let's try to solve this problem together.

There are thousands of complaints about mobile operators on the Internet - people complain that they are experiencing communication problems. Unfortunately, no one will make sure that the signal is received everywhere and with the same strength. It is impossible for economic reasons, it is impossible for some physical reasons. Russian operators generally perform well, and their coverage area is decent - this is confirmed by evaluative comparisons with European operators. You're just a little out of luck with the location.

If you complain about the poor signal level of MTS in your area, nothing prevents you from interviewing your neighbors and finding out which operator they use. It is quite possible that Beeline or MegaFon will work much better for you, pleasing with a stable reception. Even Tele2, which is not always characterized by a wide coverage area, has significantly increased the coverage of its networks in recent years - you can try.

Transferring a number to another operator

You can argue - they say, I do not want to change the operator, even if the signal from another operator is caught many times better. This is called "in spite of my neighbor's frostbite ears." Don't change if you don't want to - sit in the wilderness and enjoy the lack of communication. For others, we can offer a reasonable solution - if in your area MTS is not caught, but Beeline is caught, go to the Beeline office and write an application for number portability.

The advantages of this approach:

Already in 8-9 days you will have it working mobile phone- it will be served in the network of another operator, and you will forget what a bad network coverage is.
You will be able to choose a more profitable tariff plan.
You will remain with your number - it is not necessary to change it at all.

This is the best way to deal with poor cellular signal reception, but it will require some preliminary research - you need to decide which operator works best in your area.

Buying another phone

This is not to say that this is the most optimal way to solve the problem with poor signal reception. All modern tubes have approximately the same sensitivity. Therefore, buying another smartphone can result in unnecessary expenses. And the talk of Apple fans that iPhones are "caught anywhere" is nothing more than a myth.

Finding a phone with a high sensitivity for poor reception conditions is problematic. A few years ago they were there, but then they disappeared somewhere. People living in remote areas are advised to look for old Nokia and Motorola mobile phones - they were distinguished by increased sensitivity.

DEXP Larus X2 rev. 2.
BQ Rome BQD-2051.
Termit FixPhone v2.

Their cost does not exceed 3000 rubles, and the antennas sticking out of the housings will provide increased sensitivity.

The most difficult thing is to solve the problem with the reception of 3G and 4G signals, since only modern phones work with them.

Using external antennas

External antennas will help improve the quality of voice communication and increase the speed of mobile Internet. They connect to telephones equipped with appropriate jacks. Unfortunately, they are equipped with extremely limited quantity models. Let's see what kind of handsets we can connect external antennas to to improve cellular signal reception:

Huawei ETS5623 is a landline cell phone complete with a remote antenna and a 10-meter cable roll. The cost is about 4 thousand rubles. An excellent solution for poor reception of cellular networks.
Runbo H1 is a very expensive smartphone worth almost 60 thousand rubles, made in a shock-resistant and waterproof case. It is equipped with a connector for external antenna.
Kit MT3020B is another stationary device equipped with a socket for an external antenna, which is supplied in the kit. The cost of the phone is about 5.5 thousand rubles.

We also recommend paying attention to the tubes of the last decade - they were often equipped with antenna connectors (including those hidden under the back cover) to work in conditions of poor cellular signal reception.

Cellular communication is needed not only for voice transmission, but also for access to the mobile Internet. And if we cannot find a smartphone with a connector for an external antenna, then there are a lot of 3G and 4G modems with them. An antenna can be connected to literally every second modem, which will significantly improve the reception quality.

Passive repeaters

The use of passive repeaters allows you to improve cellular signal reception without expensive electronics. Most often these are home-made devices, which are a bunch of two small antennas. Also, beer cans, copper wire, and some other unthinkable household products are involved in the designs. All this is not serious, and even restricts the freedom of movement around the house - you have to talk on the phone when you are directly next to such a repeater.

There is one more interesting technical solution. If your smartphone does not have an antenna jack, you can proceed as follows:

Buy one directional GSM antenna and one whip GSM antenna.
Install a directional antenna on the roof of a house, on a tree or a pole up to 10 meters high (the more the better).
Install a whip antenna in your home.
Connect both antennas with a cable.

Now, literally every second citizen of the Russian Federation needs access to the Internet. However, there are times when in any village, village or just on the outskirts of the city it is not possible to connect to the 3G signal of a mobile operator. This is an ordinary phenomenon, since the signal is very strongly distorted by natural obstacles: trees, buildings, etc. If you want to improve 3G reception, you will need a signal amplifier or a 3g antenna.

So, the 3G signal can be amplified:

without the use of special equipment;
using antennas.

Amplification without the use of special equipment

In order to increase the signal strength indoors or in the country, it is necessary to make sure that the signal reaches the antenna of the phone or usb modem as much as possible. If the usb modem is connected to a Wi-Fi router, then using an extension cord it is better to bring it as far as possible outside and fix it somewhere higher, for example, under a visor. As a rule, this method is effective. If this does not help, you can make an analogue of a satellite dish from a bowl or saucepan. The signal is shielded from the surface of the "dish" and the power is increased.

Amplification with antennas

If you really don't want to waste time building such installations, then you can buy a regular antenna amplifier. Fortunately, in various stores and on Internet sites for sale Chinese goods There are a lot of such antennas. The antenna itself is an installation in which a transmitter is hidden, which increases the level of the mobile signal by several times, in comparison with a telephone antenna or a USB modem antenna. Such a device will cost about 1,500 rubles.

It seems that nowadays cellular communication is everywhere. Certainly in large cities it is everywhere! And in provincial villages, of course, it is weak or not at all. This conventional wisdom is often misleading. Since even in large metropolitan areas there are many "blind spots" where the improvement of cellular communication is required.

Why is there a need to improve mobile phone reception?

At the heart of all problems with mobile communications is the shielding of the cellular signal by objects or the greater remoteness of the base station. The signal can be shielded by neighboring buildings, building walls, floor slabs and more. Therefore, improving cellular signals becomes necessary.

Ways to improve mobile connectivity

In order to improve communication on the phone, you can try to hold it when talking in a different way - with two fingers instead of the whole palm, for the upper part, for the middle or the bottom of the phone, or transfer it to the other hand. The fact is that a person's hand can cover the antenna built into the phone and significantly degrade the quality of its work, which becomes critical in areas with poor reception.

As a rule, cellular communication improves if you go up a hill - a hillock, hill or attic of a house. To improve communication on the phone, you can change cellular operator since base stations different operators are located in different places and operate with different powers.

How to improve mobile communication using a repeater

However, often all of the above methods do not give the desired result or are simply inconvenient. If you want to improve the quality of cellular communication at home, in the office or in the country, then the most convenient and effective method- install a cell signal amplification system. Such a system consists of an external antenna, which is installed outside the room (on the wall or on the roof), a repeater and an internal antenna, which are located inside the room. This system creates a "coverage area" within which you can talk on your mobile phone without any problems. - VEGATEL VT-900-kit or SOTOBOX self-installation kit

Puzzled by the search for a device to amplify the cellular signal, the buyer is faced with an abundance of brands, models, manufacturers, which usually baffles him. What should you choose to improve your mobile communications? The engineers of our company daily solve the problems of customers to improve the quality of cellular communication. After long-term operation of the equipment for signal amplification mobile communications different manufacturers, our company has made a choice in favor of the Russian manufacturer VEGATEL. For ourselves, we decided that this is the best of what is presented on the domestic market.

VEGATEL equipment is distinguished by:
Optimal price-quality ratio. VEGATEL equipment does not belong to the equipment of the lowest price segment. However, the quality and stability of its work is much higher than its Chinese counterparts. This equipment always delivers the characteristics declared by the manufacturer and does not interfere with the base stations of cellular operators.
A wide range of amplifying equipment, in which there is a large number of dual-band repeaters, which allows you to amplify all cellular operators operating in a given area at a low cost.
Technical support all clients. In case of difficulties during installation and during operation, you can always get full advice from VEGATEL specialists.
A full range of everything you need to implement projects to strengthen cellular communications. VEGATEL produces not only repeaters but also boosters, antennas, antenna amplifiers, attenuators, splitters and splitters.

Despite the widespread use of mobile communications, the question of how to strengthen the signal of the phone, or rather the cellular connection to which it is connected, is still relevant. It doesn't matter if you live in a small village or in a metropolis, the likelihood that your device will stop picking up a signal is everywhere. Gradually, this problem is being solved by operators, new base stations appear, communications are increasing. What if the problem lies with your phone and not the network? Today we decided to figure out what the bad signal level is connected with and whether it is possible to fix it with our own hands.

The principle of cellular communication is quite simple: there is a base station of the operator and your phone, a radio frequency channel is organized between them, through which SMS messages are transmitted, calls are made, data is exchanged on the Internet. There are several standards for cellular communication, differing in the signal transmission method and frequency. As a rule, base stations are erected on higher elevations in order to provide maximum coverage. However, you can't get away from the obstacles that prevent the signal from passing through. It can be walls, trees, and other obstacles, upon contact with which the signal weakens.

It is clear that in an open area where high-rise buildings do not abound, the coverage area will be higher. For example, for stations operating according to the GSM-900 standard, in this case, the zone is no more than 30,000 kilometers. In urban areas, the figure is reduced to 7 kilometers. Stations with more advanced communication standards such as 3G and LTE cover an area that is half the diameter.

Why do we have a weak phone signal?

Due to the above mentioned barriers, so-called dead zones or holes in the coating can form. That is, places where the signal is weak, unstable or completely absent. Where people most often encounter a bad signal level on the phone:

places located at a significant distance from the nearest station (there is simply no coverage);
basements, underground parking lots, lowlands (the signal cannot simply penetrate here);
hills, skyscrapers (often “to rise higher” does not mean the presence of a signal - above the 12-14th floor there is often no signal at all);
buildings made of metal structures that do not transmit a signal.

However, obstacles and remoteness from the station are not always the reason for the lack of a signal. The user's phone is often the cause. You have probably been in situations where a friend has a cellular signal, but you do not. And at the same time, you use the services of one operator. It is common for two identical phones to have different signal levels. There can be many reasons:

a phone in a metal case or in a metal case can catch the network much worse than a plastic device;
quite often, no matter how surprising it sounds to you, the reason is the "clumsy" firmware of the phone;
damage to any components as a result of falls, immersion in water, and so on;
the phone may have a defect in the antenna from the factory, which is especially the case with Chinese manufacturers of inexpensive models.

How to amplify a phone signal with your own hands?

Well, let's go over the theory, let's move on to practice. We will look at several ways to amplify a cellular signal, from the simplest to the most complex and expensive.

The reason is the firmware

It is worth starting with checking the correctness of work software tools before trying to get to the insides of the phone. Hundreds of users face the deterioration of the communication signal after flashing, so attention should be focused. we have already written, so we will not repeat ourselves. Firmware is a fairly simple process, but with its own nuances. Just remember to back up your important files.

If the flashing helped, then we congratulate you, if the phone still does not catch the network well, then move on to the next item.

The signal is poorly picked up due to damage to the phone

As already noted, the phone often picks up the signal poorly after accidentally falling on a tile or plunging into the sea. In this case, the average user has no choice but to go to service center... Modern phones are pretty complex devices, therefore, it is not possible for the majority to identify the source of the problem on their own. It is likely that specialists will detect damage and perform the necessary work so that your phone can again cope with the network search without any problems.

How to amplify a phone signal with your own hands

In most cases, the reason for a weak cellular signal lies in a defect in the antenna, which, in fact, is responsible for this function. Often, owners of inexpensive smartphones from the Middle Kingdom are faced with the fact that the manufacturer cheated a little by loosely connecting the antenna to the motherboard of the device. You can correct the mistake yourself, but you need at least a little understanding of how the phone works. Otherwise, we contact the service center with a description of the problem.

today smartphones are represented by a very different design, therefore, they are disassembled in different ways; the easiest way to get to the insides of a phone with a removable cover and battery is more difficult when the smartphone is not separable;

Do not hurry... Before starting the disassembly, find a video or text material on the Internet that will show and tell you how to disassemble your specific device, what you should pay attention to.

Please also note: after disassembling your smartphone, you lose your warranty.

as a rule, the antenna is hidden in the lower or upper part of the case, represented by small copper strips (again, for the location of the antenna specifically in your model, see the corresponding materials);
after you get to the board, you will find several spring contacts, which should fit snugly to the ribbon cable located on the back of the structure;
if the spring contacts of the motherboard do not fit well with the ribbon cable, carefully correct them, armed with, for example, tweezers;
we collect the phone and enjoy a good network signal.

We connect a homemade antenna to the phone to amplify the signal

The above methods only work if the problem lies in your phone. But, as we noted at the beginning of the material, the cause of a bad signal can be various kinds of obstacles or a significant distance from the station. In this case, you can try to amplify the antenna of our device with just a piece of wire.

Immediately, we note that the method is not suitable for all phones. The fact is that for its implementation you will need a special diagnostic port, which is difficult to get to in a modern non-separable smartphone (in a number of models it cannot be found at all). It looks like a small round-shaped connector in golden color.

take a small piece of thin insulated wire;

insert into the connector;

we put it so that it does not interfere with other components and the closure of the lid.

Everything, as practice shows, the signal of the telephone network is greatly enhanced. Isn't it amazing ?!

Some users inserted a piece of wire into the 3.5 mm port (under the headphones). Sometimes it works too.

Sticker or foil to enhance the phone signal

In the vastness of foreign online stores, it will not be difficult to find a bunch of different devices for signal amplification. Among them, a small sticker-sticker is popular, which is a few metal tracks, which, according to the manufacturer, allow you to get rid of interference.

Similar stripes can be seen in some smartphones by default, so the “magic” properties of the sticker have a right to life.

However, to achieve a slight improvement in the signal, according to a considerable number of users, a piece of ordinary foil will help. It is located under the phone cover, closer to the antenna. The method is simple, so you can try.

Strengthening communication using a repeater

In some cases, when the signal cannot be amplified by any of the methods (too thick walls of the room, distance from the base station), they resort to using special antennas or repeaters. Such devices can significantly enhance the signal, but their cost often scares off a potential buyer.

Where to buy cheap?

You can build something similar with your own hands, but often it does not amplify the signal at all or does it very, very badly.

For example, some people use the following method:

we take a metal rod (50 cm is enough), a coaxial cable, a piece of foil (about 10x4 cm) and plywood or plastic;
we bend the metal rod so that we get a rhombus-shaped structure;
glue the foil to the plywood;
the metal rhombus and the foil are connected by means of a coaxial cable (soldered);
the end, on which the rhombus turned out to be, we raise it higher, the other, with foil, we leave it at the bottom;
we bring the phone to the foil to check the signal quality.

You will probably need to find the most suitable location for the resulting structure to pick up the signal.

It is clear that such an amplifier is unlikely to provide communication for a large company that was not lucky enough to have an office in an area without network coverage. Here you will already have to seek help from specialists. Today, many companies provide such services, and not only will offer modern equipment, but will also be engaged in installation. By the way, it is not worth saving on specialists - for installation, workers use special devices that help determine the most suitable place, select frequencies, and so on. An ordinary user, of course, will find it difficult to cope with such a task.

On the positive side, engineers have already come up with several options for getting rid of such inconveniences. The disadvantages include the requirements for additional financial investments and the complexity of setting up communication amplification systems. However, let's not get ahead of ourselves and tell you about all this in order.

Signal booster for mobile phone

The simplest way to avoid a weak signal is to install the amplifier not on a specific area or building, but on a specific phone. Similar antenna amplifiers look like stickers and are glued inside the body of the device or on its back cover.

The signal is amplified by changing the directional pattern of the phone's own antenna and increasing the total induction of the two antennas.

The disadvantage of this method can be considered a change in the circular reception of a mobile phone to a narrowly directed one. Simply put, the signal will improve significantly when you point the phone towards the tower of the mobile operator. In other cases, the signal quality, on the contrary, will drop. How effective such a mobile signal amplifier is for you personally is, of course, to decide on your own.

The next way to enhance the quality of communication is a point amplifier of a mobile communication signal with a small coverage radius. This option is suitable for cases where the zone of strong signal is only a few meters from your workplace.

The ThinkGeek mobile phone booster consists of a small antenna and an amplifier itself, which plugs into the USB port of your laptop. The length of the cord allows you to cover a radius of 4.5 m from the user, and the zone of good signal will extend to 1.5 m from the computer.

The undoubted advantage of such devices is their budget, but the obvious limited action makes them ineffective for large companies.

Mobile signal booster for large areas

Effective systems that can solve the problem of poor signal in factories, in basements or, for example, in country houses, consist of a number of devices that have been properly selected and configured. The mobile internet signal amplifier has a similar structure and consists of similar components.

An antenna acts as a receiving element of such systems, which is most often installed on a mast and directed towards the tower of a mobile operator. The problem is the need to run long cables to the internal antennas, which weakens the signal strength in proportion to the footage.

To reduce signal losses, a repeater is mounted at the maximum possible distance to the receiving antenna, which amplifies the GSM signal. Repeaters are characterized by gain (KU), output power and differ in operating ranges. For transmitting an amplified signal to specific rooms, rooms, etc. use a divider that splits the signal to the internal antennas.

Indoor antennas also have their own KU and are designed for a specific coverage area.

It is worth knowing that improperly selected or assembled equipment has the opposite effect and jamming the already weak signal... Mobile operators can give a warning to the owner of such a system, and in the absence of a response, obtain penalties through Radionadzor. The conclusion suggests itself: if you are not sure about own forces, it is better to consult a specialist.

A modern 3G phone is a mobile phone compatible with 3G technologies of the third generation, which significantly increase the speed of information exchange. However, like most other mobile networks, the 3G network occasionally has problems with poor signal reception. Moreover, since 3G is constantly connecting to the Internet, the low level of cellular communication prevents you from accessing the Internet.

How to improve 3G signal

Improving 3G signal quality is not difficult if you know how. On our website, we offer you easy-to-use and inexpensive signal amplification devices. 3G data rate is directly proportional to signal strength, so by amplifying the signal you also increase the data rate. The 3G signal booster is a simple solution to many problems with your 3G network.

3G signal repeater

3G amplifiers come with two antennas - external and internal. While the internal antenna is connected to your phone, the external antenna is connected to the nearest cell phone tower. These antennas enhance and improve 3G signal reception.

Indoor antenna coverage depends on the quality of the incoming signal, so ideally the unit should be installed outside a building or near a window for better signal reception.

Benefits of a 3G signal booster

To ensure good reception, the 3G signal booster can be used anywhere, even in a car. 3G technology assumes a high data transfer rate, which is achieved with the help of this device. This not only improves the signal strength, but also increases the lifespan of your mobile phone.

The 3G Signal Booster is easy to install and easy to use, giving you seamless access to your 3G network wherever you are. This device increases your network coverage, allowing you to use your phone without interference, both for audio calls and for other tasks. By boosting your 3G signal, you also reduce the amount of radiation that your phone emits, thereby extending its lifespan and benefitting your health.

The coverage area of a 3G signal booster may vary depending on your needs. On our site provided wide choose amplifiers 3G signal.

How to improve 3G signal

Like any other repeaters or cell signal amplifiers, 3G amplifiers help not only improve the quality of signal reception on time, but also increase the data transfer rate, which is very important when using the Internet.

Thanks to the 3G amplifier, you will always be in touch with the outside world and will be able to solve all personal and professional issues promptly and without problems.

Deterioration of the cellular network is a common problem even in large metropolitan areas. Fortunately, it is not difficult to amplify the signal in the apartment - it is enough to know the subtleties and solutions to the problem.

Why are there problems with cellular communication in the apartment?

Subscribers of any operators may complain about interruptions and interference during calls on their mobiles, problems with sending and receiving SMS, as well as poor quality of the Internet connection. Problems of this kind are related to communication, and their causes are varied:

The apartment is located far from the base station antennas. Most often, this reason is possible in small towns and villages located at a distance from urban areas. The farther from the source of communication, the worse the quality of the connection. A similar problem occurs when the tower antenna is turned away from the room.
Obstacles and hindrances. Tall trees and buildings, as well as large pillars and other structures, may come across the signal path. A large amount of concrete and metal structures can prevent the signal from reaching your apartment, causing network problems.
Attenuation of the signal. The reason lies in the thick walls of houses and dense multi-layer double-glazed windows.

Important. The problem of signal attenuation is especially relevant for the lower floors and the basement - for their residents, the signal may disappear completely.

Interference, or the overlap of network signals from different base stations on top of each other. This effect is possible if the operator has commissioned a new station.

Important. Interference can cause your phone to run out of battery quickly and conversations can be interrupted unexpectedly. This is because the phone is trying to receive two similar signals at the same time.

Use of outdated equipment. It often happens that operators use low-quality or outdated towers, the work of which may not be permanent.

What is required to solve the problem?

You can solve problems with the loss of the quality of the cellular network by installing additional equipment - a router, repeater and special antennas to amplify the cellular signal in the apartment https://gsmusilenie.ru/kvartira.html.

The first option involves the installation of a 3G or 4G device that will receive an external signal using an antenna and distribute it as Wi-Fi inside the apartment. The second option involves the installation of repeaters and antennas that can directly amplify GSM, 3G, 4G.

Thanks to the compactness of the devices and their modern installation, you can not worry about the safety of the walls and interior.

How does the cellular enhancement system work?

The repeater amplification system works with GSM, 3G and 4G. This option is especially relevant for those who have interruptions in voice communication and the Internet in their apartment.

The process of installing the equipment involves the installation of a donor (receiving) antenna located on the street, as well as a signal amplifier (repeater) and service antennas located in the apartment. External and internal devices are connected with a cable. The outdoor antenna receives the signal, which passes through an amplifier and is transmitted to the antenna located in the apartment.

Internal antennas can distribute the network not only to smartphones and tablets, but also to routers, modems and other devices.

The cost of a solution to strengthen cellular communication in an apartment - what does the kit consist of and how the cost is added up

It is not recommended to perform work on the selection and installation of equipment on your own - otherwise, you can disrupt the operation of networks and get more harm than good. The cost of services of companies involved in strengthening the cellular network in apartments and country houses consists of several factors:

Apartment area and number of rooms;
Signal level in the apartment and on the street (number of divisions);
Inaccessibility and complexity of installation and configuration of devices;
Customer's wishes.

Among the main components of the cost of equipment and its installation are the area of the premises and the level of the network. The first determines the number and power of the required receivers and internal antennas, and the second determines the type, location and power of donor antennas. The larger the area of the room, the thicker its walls and the lower it is located, the greater the number and required power of devices. The weaker the radio signal in the room, the more powerful the external donor antenna should be.

Important. A package of equipment with installation, selection, specialist advice and home visits varies from several thousand to several tens of thousands. Package offers, as a rule, start from 9-10 thousand rubles.

The Internet is an irreplaceable thing in modern world... The more we need mobile Internet, the more annoying it is to find a bad signal or even its complete absence... Although the quality of cellular communication has improved in recent years, it still often fails. How to fix poor 3G signal quality and what to do for this?

Reasons for a bad mobile signal: can it be improved

Cellular problems and mobile internet can be caused by completely different sources: from distance from cell towers to bad weather conditions. Let's take a look at the most common reasons:

remoteness of cell towers;
third-party networks that disrupt the signal;
a large number of obstacles - high-rise buildings, metal structures, hills, mountains;
bad weather conditions - rains, thunderstorms, storms, etc .;
high network congestion - common in the evening;
hardware problems - for example, low battery power.

You can improve your cellular signal, and here are the most obvious and simple ways:

be closer to the cell tower;
go to an open place or to a window - so that barriers do not interfere with the "travel" of radio waves from the phone to the tower;
Recharge the device - Moving away from the cell tower requires more transmitter power, which drains the battery faster.

Unexpectedly, I found that cases and accessories made of metal - or with metal inserts - can negatively affect the signal, just like large metal structures. For the owners of such accessories, I suggest trying out the Internet speed with and without a case. You may be pleasantly surprised by the result.

Other methods are more complicated and not so obvious, they are associated with additional devices or programs. Let's analyze them in more detail.

Strengthening Connectivity with Apps: Pros and Cons

A large number of signal amplification applications are available on the Internet. At the same time, you do not risk damaging your phone and do not waste money. Let's see if this is really so?

I will analyze the software way to improve the signal using the example of one of the popular and easy-to-use applications - Internet Speed Master.

To use Internet Speed Master, you just need to launch the program and click the Apply Patch button for smartphones with Root rights or Improve Internet Connection for non-rooted phones. Whenever the signal is bad, just use the app again and the smartphone will find a strong and stable network signal.

Root-rights or "Superuser" rights are full-fledged access to all device data. Thanks to Root rights, the user can get “unlimited” access to all files on the device running Android.

Wikipedia
https://ru.wikipedia.org/wiki/Root

Internet Speed Master has an extremely simple and intuitive interface

Be careful if you want to root. Careless use of "superuser" rights can easily turn a smartphone into a "brick". Better to play it safe once again than to regret the loss of the device later.

Let's consider all the pros and cons of this application and the method in general.

Pros of the programmatic method:

simple and intuitive interface for most applications;
the method does not require material costs;
applications do not require your intervention - just press a couple of buttons;
the method can be checked in a couple of minutes, without even leaving home.

Cons of the programmatic method:

not all devices give a positive result;
many applications require Root rights.

The disadvantages versus the advantages are negligible. It's safe to say that trying this method with a bad signal will definitely not hurt.

Using purchased or homemade antennas to enhance communications

Cellular signal strength is measured in decibels (dB) and ranges from -50 dB (excellent signal) to -120 dB (no signal). Antennas, repeaters, repeaters and other equipment raise this level, improving communication.

Cellular signal quality ranges from -50 dB to -120 dB

You can find out the signal strength on Android in the following way:

If the previous method provided an insufficient improvement in the signal quality, then it is worth trying to increase the communication speed using the antenna. The cost of a purchased antenna starts at 1300 rubles. The range of equipment is wide enough among both Chinese devices and Russian manufacturers.

A whip antenna is an inexpensive and easy way to amplify a communication signal

The main difference between antennas is the directional pattern - the most common antennas are with circular (can pick up a signal from all sides) and directional (maximum effect when directed towards the cell tower) patterns. Also, antennas differ in shape. The most popular are pin and panel ones.

Another type of antenna is panel

If for some reason you do not want to purchase an antenna, you can build it yourself using simple improvised means. It doesn't require special knowledge, so most users can do it.

Using repeaters (repeaters)

Repeaters or repeaters are more complex and expensive devices than antennas. Prices for repeaters start at 7,000 rubles, however, they increase the signal quality even more. Even the most inexpensive devices have a coverage area of up to 200m² at good conditions(signal 3-4 sticks). And expensive models (from 40,000) may well cover several floors of an office building or a shopping center.

Repeaters are one of best devices to amplify the signal

Installation of cellular repeaters

If you have already selected a suitable device, you need to install it correctly. Of course, you can use the services of masters, but it is quite possible to carry out the installation yourself. To do this, just use the instructions:

Install the outdoor antenna outdoors. In this case, the directional type antennas must necessarily look in the direction of the cell tower.
Place the internal antennas indoors, at least five meters below the external ones.
Connect the external and internal antennas with cables, connect to the repeater.
Connect the repeater to the power supply and check the power supply.

In case you are not sure where the cellular station is, ask someone to be near the internal antenna, and slowly rotate the antenna yourself until you find the best signal.

If everything is done correctly, the signal level near the internal antenna will increase significantly, approaching the maximum.

Other 3G signal boosters

On sale you can find compact amplifiers in the form of sticker-stickers located inside the smartphone body. They are a geometric pattern of several metal stripes. The manufacturer claims that the amplifier reduces interference and improves the signal in areas where it is almost absent. On the AliExpress website, such stickers are sold in 10 pieces for only 140 rubles, but their effectiveness, as they say, relies on chance and according to most reviews, there is no increase in users.

Small stickers like this can improve communication

Instead of such stickers, many ordinary users and even experts argue that even an ordinary piece of foil located under the phone cover helps to get an increase in the signal. This method requires minimum costs, therefore it is quite suitable for testing.

The main reasons for a bad signal lie in the remoteness of cellular stations and wilderness, but the quality of communication is somehow improved with the help of simple and not very simple means. Simple manipulations give a solid boost to the communication speed. It remains only to wish fast Internet!

In the villages, up to the present moment, there is no dedicated Internet line in most cases. It happens that the Internet can be connected via an ADSL line, who has a connected landline phone.

In most cases, all rural residents of Russia connect to the Internet using 3G modems. And the further the village is, the worse is not only the 3G Internet, but also the usual cellular communication.

To improve the quality of communication, the following amplification principles are used:

Using an antenna.
With antenna and amplifiers.
With multiple antennas and multiple amplifiers.

There are ready-made kits, but before buying them, you need to determine what to enhance and how. Sometimes one antenna is enough and sometimes not.

You need to know exactly in which range the 3G signal of the selected telecom operator is transmitted, and where the boundaries of this signal are. A regular cell phone or spectrum analyzer will do the trick to check the signal strength.

Checking the signal level

Before you strengthen anything, you need to catch something. We determine the range of working frequencies of voice and Internet. The image above illustrates the entire spectrum of the frequencies involved: television signal, wi-fi, DECT, GSM, LTE, etc. It is important to understand in what range the base station at the point being checked is transmitted by the Internet. It can be transmitted in UMTS 900 and UMST 2100.

In Russia, 3G signal has its own standard: UMTS 900 and UMST 2100.

All smartphones and 3G modems work using both these standards. In cities due to the small radius of coverage, but more high speed signal transmission and stability of work with a large number of connections, use the UMTS 2100 standard.

If you are not an installation organization specializing in installing 3G boosters for a one-time connection, you can use a 3G-enabled phone. We activate the built-in Netmonitor function in it.

Search the Internet for how to do this on your phone. Here are the most common codes.

Phone model	Menu entry code	Note
Apple iPhone	* 3001 # 12345 # *, press "call"	2g, 3g, 3gs, 4g, 4gs, 5. For firmware versions 5.0.1 and higher.
Android	* # 0011 # or * # * # 4636 # * # * or * # * # 197328640 # * # *	The menu should appear automatically after entering the last character, if not try another code
HTC (EVO, Incredible, Touch)	## 33284 #, press "call"	Select a network in the menu and see the signal level
HTC Wizard 8125, 2125	##364##	The signal level is displayed in conventional values. The higher the value, the higher the signal strength
Htc touch	##33284#	—
Samsung C170, X820	#99990#	—
LG C900	##634#	If you ask for a password 2277634 # * # and press ENTER
Nokia 6215i, 6315	##2773	further code 000000

When we enter the engineering menu, various information appears, for example, the volume level, battery charging, IMEI, wi-fi, phone usage statistics. I do not recommend changing the values.

If you cannot find the parameters you need, please use a different phone. As a result, you need to define the Rx CH parameter. The first value surrounded by a red frame shows in which range the signal is received. If the value is within 10562-10838 it is UMTS 2100, if within 2937-3088 it is UMTS 900. Having determined the range of operation, you can accurately select a 3G signal amplifier, for example, high-quality Picocell 900 or Picocell 2000.

The yellow frame shows the level of 3G signal reception. Having constantly changing dynamic parameters of the signal level, we are looking for the best reception point. Less is better. Ideally, it is better to place the antenna higher on the roof, but you can find points of reliable reception inside the house.

Equipment selection

If you are in the reception area, it may be sufficient to install a good antenna with high gain. For example, an AP-1900 / 2700-17 antenna with a gain of 17 dB, but a narrow radiation pattern. Suitable if one base station is installed next to you and there are no other signal consumers nearby.

An antenna of the AO-2000-11 brand shows a fantastic result - with a high KU = 11 dB and a circular directivity pattern. It works on the set and forget principle. Its advantage lies in the principle of operation. It can pick up a signal from several base stations at once, which significantly affects the speed of the Internet. No need to look for the direction of the signal.

In almost 80-95% of cases, when the 3G signal is somehow caught, it is enough to screw the 3G repeater TAU-2000 from Picocell to the antenna, and you will catch a stable 3G / 4G signal.

To prevent signal loss between the antenna and the amplifier, I recommend using a cable with a large cross section, the tips of which are crimped industrially or with a special tool.

Ready-made kits

When you know exactly what type of amplifier you buy and whether you need it at all, you can start buying equipment. If in your city there is no retail outlets sales, buy from online retailers or directly from an equipment manufacturer.

Kits can be of several types:

without amplifier;
with an amplifier;

Consider kits without amplifiers. These kits include an antenna and a wire. Conveniently, if you have a modem or router, then the cost of strengthening the 3G / 4G signal will be minimal. A set of wires and an antenna will cost you from 5000 rubles.

Antennas are selected based on the terrain, number and distance to base stations. This kit can always be increased with an amplifier, the final price of the equipment will rise, as will the quality of the received signal.

Any antenna can be used, including those given in the selection of equipment, but it is better to buy a modem Huawei E392, although its price starts at 3200 rubles.

Take a look short video of everything stated in the article, if anyone is interested in the subtleties, go to the site indicated in the video clip.

And finally, I will share my observation: buy an antenna and equipment in specialized stores, and not in the salons of cellular communication, what they sell there does not work.

The Connect antenna is made for the beauty of the interior. The usefulness of this device is questionable. Can only be used as an extension cable for a modem

Ask questions if something is not clear. Good luck with your shopping.
