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 a 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 do not want to waste time building such installations, then you can buy a regular antenna amplifier. Fortunately, there are a lot of such antennas in various stores and on Internet sites selling Chinese goods. The antenna itself is an installation in which a transmitter is hidden, which increases the level of the mobile signal by several times, compared to a telephone antenna or an antenna of a USB modem. 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. As 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 large remoteness of the base station. The signal can be shielded by adjacent 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 the cellular operator, since the base stations of different operators are located in different places and operate with different power.

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 way is to install a cellular signal amplification system. Such a system consists of an external antenna that is installed outside the room (on the wall or on the roof), a repeater and an internal antenna that are located inside the room. This system creates a "coverage area" within which you can easily talk on your mobile phone. - VEGATEL VT-900-kit or SOTOBOX self-installation kit

Puzzled by the search for a device to enhance 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 equipment for amplifying the signal of mobile communications from various 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.

A full range of everything you need to implement projects to enhance 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. Operators are gradually solving this problem, new base stations appear, and communications are increasing. What if the problem is 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 method of signal transmission and frequency. Typically, base stations are erected at 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 open areas, 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 poor signal strength 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 (quite 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. Cases are common when two identical phones 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 defective 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 the software before trying to get to the insides of the phone. Hundreds of users face the deterioration of the communication signal that appears 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, but 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 the service center. Modern phones are quite complex devices, so most people cannot 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.

1. 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;

Take your time... Before starting the disassembly, find a video or text material on the Internet, which 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.

1. 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);
2. 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;
3. if the spring contacts of the motherboard do not fit well with the ribbon cable, carefully correct them using, for example, tweezers;
4. assembling the phone and enjoying a good network signal.

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

The above methods only work if the problem lies with 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, a special diagnostic port is required, which is difficult to reach 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 closing 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 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, remoteness from the base station), they resort to using special antennas or repeaters. Such devices can greatly 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:

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

You will probably need to find the most suitable place 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 have to seek help from specialists. Today, many companies provide such services, and not only offer modern equipment, but also install it. 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, etc. An ordinary user, of course, will find it difficult to cope with such a task.

The positive point is that 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 signal area is only a few meters from your workplace.

The ThinkGeek cell phone amplifier 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 suburban homes, consist of a number of devices that are selected and configured properly. 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. To transmit the 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 muffles an 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 confident in your own abilities, it is better to turn to specialists.

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.

Repeater 3G signal

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 using 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 the 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 \u200b\u200ba 3G signal booster may vary depending on your needs. Our site provides a wide selection of 3G signal amplifiers.

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 quickly and without problems.

Strengthening the 3G, 4G signal is actually not so difficult. There are several ways to improve communication in the country or in the village. This can be done by:

• change of mobile operator;
• fine-tuning the modem itself.

To fix the situation with slow internet, you can also use a special external or internal 3G internet booster. The use of such equipment can actually have a very good effect.

How to choose the right operator

The towers of mobile operators in our country are located extremely unevenly. To find out which company's signal in a given area will be the strongest, you first need to look at special coverage maps. They are available for every popular operator. You can find cards on the official websites of the cellular providers themselves. In the opinion of many Internet users, the signal from the Megafon operator is best received in remote areas. However, of course, in some cases the best connection may be from other companies.

You can, of course, find out the signal of which company is better received in a particular area, not only with the help of maps. Summer residents and rural residents who want to strengthen the Internet should, among other things, ask their neighbors which operator they prefer.

Strengthening 3G, 4G signal: modem settings

To make the 3G modem itself work better, it is worth making a few changes to its settings. To do this, you just need to open the program supplied with the device and go to the "Network Settings" tab. Next, select the item "3G only" and put a checkmark in front of the line "Automatic".

Strengthening the 3G signal in the country or in the village using an antenna

Antennas designed to amplify a 3G signal are internal and external. The first type of equipment is cheaper and easier to install. External antennas are more expensive and more difficult to mount.

Indoor models can provide good 3G, 4G signal amplification simply by being installed on the windowsill. Recently, parabolic antennas of this type have become very popular. The modem is connected in focus to a special connector. Further, through the USB plug, the structure is connected to a laptop or computer. The internal antennas deserve really good reviews from consumers. They actually amplify the signal very well. But only if the operator's tower is nearby.

In very remote villages, of course, the best option to speed up the Internet can be an external antenna to enhance the 3G signal. Models of this type are usually mounted on the roof of a house or on a large tree. The choice of a particular type of antenna in this case will depend mainly on the signal strength of the operator. The weaker it is, the more expensive equipment of this type will have to be purchased.

How to choose the right internet amplifier for a summer residence - TOP-7 best devices [Rating]

With the help of an Internet amplifier, you can significantly improve the signal quality in the country, at home and in any other room.

Effective devices have been on the market for a long time.

These are the so-called extenders or extenders.

Their main task is to expand the existing signal.

In rural areas or in a place where there is very weak network coverage, it makes no sense to use an extender, since the poor quality of the Internet in this case does not depend on the router, but on the poor network of the operator.

Perhaps there are not enough towers on the territory, the connected ones have a low bandwidth, or buildings, forests and so on "interfere" with the signal.

To solve the problem of poor internet in a private house, we recommend using repeaters Are special gadgets that can increase the speed of the Internet several times by reducing the signal-to-noise ratio.

You can improve the quality of the network using special kits for strengthening the 3G-4G signal.

Content:

When choosing an amplifier kit, you should pay attention to the following parameters:

• Coefficient signal amplification. It is customary to consider the values \u200b\u200bof the indicator, which are 8 dB and above - the normal level of amplification. Such repeaters are perfect for use in areas remote from the city;
• Frequency range - this is a kind of reproducible band. The larger it is, the more efficient the repeater will work;
• Mount type. In order for the amplifier to be able to catch the already existing signal from the tower, it is necessary to install its antenna as high as possible. Typically, users choose to install the roof of the house. When buying a product, first decide on the type of fastening, and then select the options that are suitable for yourself;
• Kit cable length ... Determined by the peculiarities of the location of all devices in the set;
• output power (from device to base station).

Also, you should pay attention to the temperature range at which the device will work in normal mode.

If you live in a region characterized by frequent frosts, this indicator will be almost the main one when choosing a gadget.

When choosing an amplifier, consider your location, the approximate distance from the nearest tower to the house, the required number of connection points. Remember that the total baud rate achieved by the amplifier will be shared among all.

A mobile phone is an essential attribute of a modern person's life. It allows you to communicate, promptly receive information and conduct business negotiations. It is possible to expand the possibilities of cellular communication thanks to the access to the world wide web, which is provided by the operator. Internet access is provided by a 3G modem, which allows you to connect a laptop.

However, a weak signal makes the benefits of civilization inaccessible. To independently strengthen the cellular signal, you will need to determine the cause of the deterioration in communication and choose the best way to improve the quality of reception.

Reasons for network failures

\\ n

The main reason for the weakening of the cellular signal is the problem of poor coverage due to the remoteness of the relay towers. Most often, residents of cottage settlements and villages located far from large settlements encounter it. Low population density reduces the cost-effectiveness of installing new repeaters, thus creating areas where reception is unstable or completely absent.

Other reasons for the deterioration of mobile communications are:

\\ n
• The presence of interference. They arise from terrain, high-voltage power lines, large forest stands and similar obstacles. The reasons for the appearance of interference inside the house are microwave ovens and other equipment operating in the microwave range.
\\ n
• Nuances of construction and location of buildings. Strengthening the cellular signal will be required in cases where a country house was built in a lowland, and the phone is located below ground level. The penetration of the radio signal is impeded by both thick walls with a dense structure and facades with sheet metal materials.
\\ n

\\ n

Sometimes difficulties with the phone appear due to the settings of the base station. In this case, you will need to contact the operator who will carry out the reconfiguration and eliminate the problems encountered.

Phone problems

\\ n

Weak or no signal can also be caused by damage to the mobile phone. These include:

\\ n
• malfunction of software;
\\ n
• deformation of the case and phone parts resulting from falling products or ingress of moisture;
\\ n
• antenna defects, which often occur in inexpensive smartphones.
\\ n

\\ n

In addition, reception is significantly impaired due to the metal case or case. To strengthen the signal on the phone, you need to troubleshoot with your own hands or with the help of specialists in this field.

The easiest option is the absence of a radio signal with a loose fit between the antenna and the smartphone's motherboard. To troubleshoot you will need:

\\ n
• disassemble the communication device using the instructions;
\\ n
• check the tightness of the contacts to the loop located on the back of the structure;
\\ n
• fix the spring contacts with tweezers.
\\ n

\\ n

However, such manipulations can void the warranty, so if problems arise with your smartphone, it is better to contact the service department.

Improving the reception "folk ways"

\\ n

For confident reception in the country or in a country cottage, you can try to make a cellular amplifier yourself. It will enhance the performance of the antenna and improve the retransmission. Depending on the model and brand of the phone, the antenna amplifier functions as follows:

\\ n
• a small piece of insulated wire that is placed in the diagnostic port;
\\ n
• a special sticker representing a sticker in the form of several metal tracks;
\\ n
• a small piece of foil to be placed close to the antenna.
\\ n

\\ n

A greater effect can be achieved in improving the signal of the modem. To do this, remove the case from it, and then 4-5 turns of thin copper wire are wound around the standard antenna of the device. Its other end is connected to an improvised antenna made of an aluminum can with a cut off top, loose in the form of a "chamomile".

The purpose of the repeater and its installation

\\ n

However, homemade antennas and repeaters can only slightly improve reception. To ensure a reliable signal in the country or in a private house in the village, it is necessary to install a factory-made antenna and repeater.

How to install a cellular amplifier by yourself? First you need to purchase a set of equipment, which includes:

\\ n
• GSM repeater that amplifies the signal. Repeater models differ in gain and frequency ranges.

To install a cellular booster yourself, you need to find the optimal location for an outdoor GSM antenna. A place with the maximum reception power and the absence of various obstacles is suitable for this. You can achieve the greatest effect if you install an outdoor antenna on a mast or a special bracket. The higher its location above the house, the more confident the reception will be. In this case, the antenna should be located below the lightning rod, since the set of equipment for improving the radio signal reception usually does not have a galvanic isolation.

Then you do the following step by step:

• Install the device to amplify the radio signal. Do-it-yourself installation of the repeater does not require special skills: it is fixed on the wall with self-tapping screws.
\\ n
• Install the internal antenna so that the distance to the GSM receiving antenna is at least 10 m. The gap can be reduced if there is a possibility of separating the GSM antennas with a concrete wall.

• Connect the cable connected to the outdoor antenna to the rest of the amplifying equipment.
\\ n
• Check the correct installation and connection of antennas with a GSM signal amplifier, and then turn on the power.

The repeater is usually ready for use. However, some models are equipped with displays and switches to fine tune the receiving power and frequency. If you are going to independently install a cellular amplifier, it is better to avoid such equipment. You can install it yourself, but further manipulations require special skills and knowledge.

Ecology of consumption. Manor: Can you imagine modern life without the Internet and cellular communications? How can you conduct home improvement if all kinds of tips and tricks from your favorite construction portal are not available where they are so needed? There are some ways to improve and enhance the quality of signal reception, and today we will tell you about them.

Determine the cause of cellular network failures

Residents of cottage settlements far from the city limits are well aware of the problem of poor cellular coverage. It seems that the area is quite respectable, and the infrastructure is generally good, and mobile communications are constantly failing. This is quite understandable: the low population density makes the installation of new repeaters unprofitable, and can you keep up with modern new buildings?

The situation can be complicated by relief folds, forest plantations, high-voltage power lines and other obstacles that screen the signal or clog it with interference. And the conditions in the subscriber's dwelling are not always favorable: the house may be in the lowland, the modem / telephone - below ground level. Walls can be thick and dense, and exterior cladding can be made of sheet metal - all of which prevents the penetration of radio signals.

Difficulties with reception are also common due to low noise immunity of devices. Microwaves and microwave power equipment can create incredible amounts of interference and jam not only cellular communications, but also local wireless networks.

In rare cases, the problem is with the base station settings. Here it is, within the line of sight, but the signal level is still weak even on the street. In this case, the issue is resolved exclusively by a collective (petition) appeal to the cellular company, in response to which the operator reconfigures the station and modulates the signal in accordance with the newly discovered "blind spot" in the coverage.

Recommended BS offset for different signal types

In open areas, the station provides identification by telephones within the range of 40-50 km, but reliable reception is possible only within a radius of about 30 km from the tower. There is another subtlety, which is that the station is not just a radio signal transmitter, as for FM receivers. Mobile communication is broadband, that is, the signal can be transmitted at different frequencies, depending on the type of transmission (SMS, calls, streaming Internet), plus the exchange of signals occurs in a two-way manner.

The higher the established connection speed, the higher the transmission frequency should be, and the higher the frequency, the shorter the distance over which the radio wave can propagate in a solid environment. This explains the tolerable quality of GSM voice calls in the absence of 3G coverage, for which the transceiver is forced to work at a higher frequency.

The very first and most obvious way to establish a normal connection is to call the service provider's call center with a request to optimize the connection parameters. So you can weed out a whole layer of problems associated with incorrect configuration of equipment. If that doesn't help, welcome to the world of amplifiers, repeaters, receiving and transmitting antennas.

Do "folk" methods of amplification work

Going through the aforementioned technical means for amplifying the signal, one involuntarily asks the question: is it possible to assemble some kind of improvised device yourself, which is capable, if not of ensuring confident reception and transmission, then at least a little to improve the state of affairs?

Unfortunately, when it comes to a mobile phone, nothing can be done. You may be able to amplify the signal from the base station, but the power of the built-in transmitter of the phone to establish feedback will still be insufficient.

With modems, the situation is somewhat simpler. Their transmitter is less limited in power for the reason that the device is not mobile and there is no point in saving battery power. That is, in theory, the situation can be improved by constructing a directional antenna, but this is only in theory: there are many modem manufacturers and the details of their technical implementation are very different.

To amplify the signal, you will need a thin copper wire, for example, from a transformer in a household power supply or an inoperative phone charger. One end of it is soldered to the bottom of an aluminum can, the top of which is cut off, and the edges are loosened with "chamomile". The bank is installed outside the building as high as possible, it is advisable to pin it on a long nail to be able to turn towards the signal source.

From the improvised antenna, the wire runs along the shortest path to the transmitting-receiving device - a modem and a telephone. The wire should be as flat as possible, without turns and sharp bends - they increase the resistance of the conductor and folds and turns form distorting filters.

In the case of a modem, you need to remove the case and wind 4–5 turns of wire around the standard antenna. The antenna itself can be in the form of a copper strip or a section of a printed circuit board with a zigzag track, do not forget to first isolate the modem from the wire with a strip of polyethylene cut from a disposable bag.

Some older generation phones are also subject to this modification. We need to find a GSM antenna that looks like a shiny brass cylinder about 2 mm in diameter with a small hole in the center. The antenna can be hidden either under the battery cover or deep in the bowels of the device. The hole in the center is a diagnostic connector for temporarily connecting an external antenna; you do not need to stick anything into it, otherwise there is a great risk of overloading the transmitter. Instead, a self-tightening loop must be tied to the wire and draped over the surface of the metal cylinder.

Of course, such methods, conventionally referred to as passive amplification, do not provide any guarantee of success. They are suitable only as a way of broadcasting a signal from the street, if it does not penetrate into the building for some implicit reason. But there are also methods that can provide you with amazing speed even at a great distance from the base station.

Installing the receiving antenna and repeater

The standard active amplification kit includes three devices:

The receiving (donor) antenna is very similar to the television antenna, but the dimensions of its elements are designed to receive waves with a length characteristic of the cellular frequency. Install the receiving antenna as high as possible and away from strong sources of high frequency interference. Usually it is attached to the ridge of the roof, but always below the lightning rod, because the active amplification complex, as a rule, does not have a galvanic isolation.

The signal repeater (repeater) receives a weak signal received from the antenna, removes all unnecessary from it and amplifies it enough to provide coverage in a small area. The repeater can be installed anywhere in the chain, but usually it is located as close as possible to the terminal of the ground loop, if the function of lightning protection grounding is provided in the design.

The internal antenna is used to transmit the amplified signal from the repeater, as well as receive the signal from the phone and transmit it back to the base station through the repeater and the donor antenna. As you can see, the diagram is quite simple and clear, but the internal antenna must be located at a sufficient distance from the donor antenna and, preferably, there is no line of sight between them, otherwise the mechanism for suppressing the complex's own radiation will not work normally.
