Strengthen the cellular signal in the country with your own hands. How to strengthen the cellular signal for the Internet in the country. We assemble an antenna to amplify the modem signal with our own hands

If the apartment has a zero level of a mobile phone signal or the connection of subscribers is unstable, then this situation can be corrected in several ways.

1. Change the cellular operator. There is no guarantee that the signal of another telecom operator will pass better, especially since the main cellular companies in Russia (Beeline, Megafon, MTS) operate under the same standards and in the same frequency range.
2. Installing a femtocell (miniature cellular base) means going through a series of complex regulatory procedures (revision tariff plans, project creation, expertise, obtaining a sanitary passport for permission from the State Committee for Radio Frequencies) within a few months.
3. Install an antenna booster, but then cellular communication will work only on one mobile phone.
4. Install a cell signal amplification system in the apartment.

Let's consider the last option in more detail:

Cellular booster capabilities

Installing an amplification system in an apartment cellular communication does not require permits, but is carried out in accordance with the requirements of the RF Radionadzor. Each qualified installer of radio equipment knows and takes into account these requirements, therefore, it is better to entrust the installation and commissioning of a new signal amplification system to a professional.

A GSM amplifier installed in an apartment (also called a repeater or repeater), thanks to wireless signal transmission, serves several subscribers simultaneously. This is a bi-directional radio wave transmission device - from operator to subscriber and vice versa.

The signal amplification system kit consists of several elements:

• external antenna,
• repeater,
• internal antennas.

An internal antenna can be one, if the area of \u200b\u200bthe apartment is less than 200m 2, or several, united by power dividers, when the area of \u200b\u200bthe apartment is more than 200m 2 and a large number of rooms. Antennas receive and transmit signals, and the repeater filters noise, selects the main receive-transmit frequency of the signal and amplifies it.

The whole difficulty of installing the amplification system lies in the correct selection and placement of antennas: they should not interfere with the operation of mobile phones of neighbors and your own telecom operator, and also not cause "self-excitation" of the repeater (when the radiation sectors of the external and internal antennas intersect). The interference caused by the amplifier is fixed and can lead to penalties, and the "self-excitation" of the repeater - to its failure

There are several benefits of a home repeater:

• the output power of a mobile phone (radiation power) decreases, which means that its negative effect on the human body decreases;
• phone batteries operate with less wear at low power, i.e. their service life increases;
• internal antennas emitting radio waves are installed on the ceiling or in a non-working area, which means that their effect on the inhabitants of the apartment is minimal.

The overall dimensions of the repeater are so insignificant (approximately 140x245x50 mm) that it not only does not affect the interior of the room, but remains invisible. When moving to a new apartment, the communication amplifier can be easily dismantled and carried. to a new location. How to properly install repeaters you can find out

Mobile phone - an integral attribute of the life of a modern person. It allows you to communicate, promptly receive information and conduct business meeting... 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

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:

• 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.
• 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.

Sometimes difficulties with the phone appear due to the settings 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

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

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

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

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

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

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

Improving the reception "folk ways"

For reliable 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 are:

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

A greater effect can be achieved in improving the signal of the modem. To do this, the case is removed from it, and then 4-5 turns of thin copper wire are wound around the standard antenna of the device. Its second 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

However, homemade antennas and repeaters only improve reception marginally. To provide 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:

• GSM repeater that amplifies the signal. Repeater models differ in gain and frequency ranges.
• External antenna. It is used to receive and transmit radio signals to the repeater and in the opposite direction.
• Internal GSM antenna providing reception by devices of subscribers.
• Cable connecting all elements;
• Power divider, which is required when connecting several internal antennas to a repeater with your own hands.

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.
• 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.
• 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 for fine-tuning 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.

When do you need to amplify the signal

If the internet connection is unstable or the data transfer rate is slow, the first step is to check the signal strength. This parameter is displayed in the modem settings. To measure the signal level on a mobile phone, download a special application. A suitable one can be found in the Play Market or App Store by request "Network signal info". The signal level will be shown in decibels. An indicator in the range from -50 to -80 is considered normal. If the indicator is from -90 to -100, the signal is weak. You can use the amplifier with an indicator of -80.

How the antenna will help

A weak signal means that the subscriber cannot use the Internet: the connection is unstable and the data transfer rate is very low. Antenna solves this problem.

The amplifier is the link between the station of the cellular network operator and the mobile phone or USB modem. It receives a signal from the operator's station, amplifies it and transmits it through a cable to a modem or Wi-Fi router.

Thus, you can strengthen not only the Internet connection, but also the cellular signal throughout the entire area. However, the antenna will only be useful if installed correctly. It is important to pinpoint the location of the nearest station and point the device in the direction of the signal source.

How to strengthen the reception of the Internet in the country: the principle of the antenna

The amplifier consists of an antenna and an intermediary - a modem or Wi-Fi routerthat supports the connection of USB modems. An internal antenna is additionally used to amplify the cellular signal throughout the house. The cost of an amplifier kit depends on the equipment that is included in it, and starts from a thousand rubles. The connection diagram looks like this: the antenna is connected to a 3 / 4G modem, which, in turn, is connected to a Wi-Fi router.

How to choose an internet signal booster for a summer residence

First you need to decide on the antenna power. To describe it, use the concept of gain. It is measured in decibels (dB). The higher the ratio, the weaker the signal from the operator station can amplify the device. However, along with the number of decibels in the characteristics, the cost of equipment also increases.

Two types of antennas are mainly used to amplify the signal:

• Wave channel (Yagi).It consists of an active and a number of passive vibrators, which are located parallel to each other on a traverse. The device has a high directional efficiency.
• Panel sector antenna. This is a compact monolithic amplifier. The characteristics are similar to the wave channel, but as an additional advantage - protection from precipitation.

You can improve the quality of the Internet at the dacha using both a wave channel and a panel antenna. Most often, the choice of subscribers is not determined technical characteristics, but the cost of the device.

When choosing equipment, you should pay attention to the connector for which the antenna is made. Standard modems are adapted for CRC9 connector.

What other equipment is needed

• USB modem with a SIM card slot. It is impossible to amplify the signal directly on a computer or smartphone, the subscriber needs optional equipment... This is the USB modem. It is connected to the antenna directly with a cable.
• Wi-Fi router. If you need to indirectly connect the device to a modem - as is the case with phones or tablet computers - you can add a router to the network that sends out a signal via Wi-Fi. The main condition is the presence of a connector for connecting a USB modem. There are models of Wi-Fi routers with SIM card slots.

You can improve both the Internet in the country and the cellular signal. If it is unevenly caught in different parts of the house, repeaters are used. Such devices consist of two modules. The first module is a receiver that is installed in the part of the house where the cellular signal is strongest. It picks up the signal and improves it. The second module is an emitter. Its task is to repeat the signal received from the receiver, spreading it in those parts of the house where communication is poor. The repeater does not need an additional SIM card or other accessories.

How to strengthen the Internet on the phone in the country

To get a stable Internet on your phone, without routers and modems, you can use transmitters. They amplify the signal from the towers cellular operators and distribute it to all devices in the house. These kits include two antennas - an external one, which is installed outdoors, and an internal one, for placement indoors. The principle of operation of the transmitter is quite simple: the subscriber fixes the external antenna towards the operator's station, setting the required location according to the indicators on the antenna display. After that, the second part of the kit is installed inside the room. When the installation is finished, the speed of the 3G internet will increase. Antennas can both improve the reception of a cellular signal and increase the speed of the Internet in the country.

If you live in an area where the signal of mobile operators is completely absent, appreciate the benefits. With its help you will get high-speed and quite stable internet - problems with the signal rarely occur, only due to heavy precipitation or wind.

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.

What is Cellular Signal?

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 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 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, 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 necessary workso that your phone can again cope with 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;

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 particular 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 against 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 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 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 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, 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 catch 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, etc. For a regular user, of course, such a task will be difficult to cope with.

Choosing a cellular signal amplifier for a summer residence

On weekends and holidays, townspeople tend to spend time away from the bustle of the city at their dachas and country houses... Many people relax with their souls, enjoying the fresh air, nature and tranquility. Others are attracted by intricate summer cottages, growing plants, flowers, and harvesting.

Despite the desire to relax, most city dwellers cannot do without cellular communication, and since the network sometimes does not catch outside the city, discomfort arises that can distract from rest. People are wondering - how to strengthen the cellular signal in the country with their own hands? A mobile phone today is not just a household item, it is a part of life, the ability to keep in touch with loved ones, control the performance of work, and remain available anywhere.

Mobile communication may not be available due to insufficient operator coverage. The quality of communication is also affected by the materials from which the country house is built.

To get out of this situation and stay in touch, many refuse the joy of a country vacation or prefer to purchase a plot with coverage. But there is another way out. You can not give up your favorite remote area and spend a lot of time on it by installing specialized equipment that can strengthen the signal of the network - an amplifier for a cellular signal and the Internet for a summer residence. This mobile phone amplifier for summer cottages provides high-quality and uninterrupted communication in any part of the house. There will be no need to look for the most suitable place to talk while trying to pick up the signal.

General information

The problem of a poor-quality network will be solved by a device called a repeater. To forget about forever poor coverage you need to install special equipment in your country house. Its work does not depend on a particular operator. What services mobile company would not be used by a person, the signal will be improved. The quality of the signal amplified by the instrument is not affected by the frequency and standards used.

The signal amplifier is at the heart of the cellular amplifier for giving. An antenna receives the network signal and the other antenna transmits. The device operates under the control of a controller and a duplexer. They are frequency filters to improve communication quality. The design of the device allows you to amplify the signal of the cellular network in both directions. The radio channel amplifies the signal for all telephones within range.

The principle of the cellular signal amplifier

The effectiveness of the device lies in the use of two antennas - external and internal. The outer is placed outside the building. For fastening, a house wall or roof is most suitable. The antenna is installed in the direction of the nearest mobile station. The antenna is connected to the main unit via a cable. An external antenna works by taking an incoming signal and sending it to an internal antenna - a repeater.

The device must be installed in a specific order. One of the key points is the length of the cable. The shorter its length, the better quality the received connection. The most practical place for fixing the device is the facade of the building. The distance from external to internal antenna should be at least 20 meters.

Additionally, you need to install power dividers if you plan to use the device over a large area. With the help of dividers, more antennas can be connected to the repeater. To do this, select places inside the room on the walls and ceilings. This allows you to receive a uniform signal of good quality regardless of obstacles such as walls and blocks.

Choosing a repeater - where to start

In search of an opportunity to enhance the signal of mobile communication in the country or in the house, some craftsmen are trying to create a cellular amplifier with their own hands. But it is much safer to put the solution of this issue in the hands of an experienced specialist than to make a homemade device or buy equipment from a manufacturer VEGATEL, which is considered one of the best in the domestic market.

But not everyone is stopped by the possibility of failure. Some masters still take on the assembly of the amplifier. The most primitive way is to connect a telephone set and an external antenna. This is the cheapest of the effective methods, but the most inconvenient, since the person talking on the phone will be tied to the place. Another disadvantage is the increased work for only one phone, so that other family members will not be able to use high-quality telephone communication.

The most practical and high-quality one is a cellular amplifier for giving a professional factory release. When purchasing a device of industrial production, you need to pay attention to such points as:

Average price;

Complete kit for installation and use;

Installation and Application Guide Appendix;

Availability of warranty repair services from the manufacturer.

Compliance with these criteria ensures the fulfillment of the price \u003d quality ratio and guarantees the result. A model that meets these requirements will last long enough and efficiently. Adequate mobile signal will be provided to all users on the site using a commercial repeater.

Installing a single repeater to enhance communication in the country is a fairly budget option. By investing a little more money, you can install a mobile signal repeater. It is more powerful and enhances not just the signal of the mobile operator, but the Internet coverage. That is, in addition to communicating by phone, you can purchase the opportunity to use high-speed Internet.

Installation and setup of a kit with a repeater

After a successful purchase of a complete repeater, it is time to install the device and use the benefits it creates.

Installation of a cellular signal amplifier for a summer residence takes place in several stages;

The first step is to measure the signal quality. This is done to properly position the external antenna and check the power of the device itself. Measurements are made using a special professional program. A place with the best signal quality is determined and an external antenna is installed here.

Next is the direct process of assembling the signal amplifying equipment. Professional help is also important at this stage. Installation involves work on the roof, operations with a hammer drill and other tools that not every owner has in stock. However, for a person who has the tools and skills to work with them, assembling the repeater will not be an overwhelming task.

The repeater should be installed near a power source to recharge the device. The repeater can be installed horizontally or vertically, this does not affect its performance in any way.

The final step is the installation of the internal repeater antenna. It is necessary to remember about the required 20 - meter distance of the external and internal antenna for successful work repeater.

After installation, the operation of the amplifying device is adjusted. Setting up is reduced to connecting cables to N-type connectors. The amplifier is then ready to perform its functions.

Setting up the device consists in setting the gains for each channel.

Conclusion

This article is devoted to the principles of the repeater for giving or country house... We hope that the collected information was useful when choosing, installing and setting up the device. This device is designed to provide users with high-quality cellular communication.

The price of a repeater depends on the country and manufacturer, as well as on the estimated capacity. We recommend the manufacturer VEGATEL, whose products are optimal in terms of price / quality ratio. Even the simplest repeater can significantly enhance the quality of coverage in the country and provide uninterrupted mobile communication with the outside world.
