How to increase the cellular signal on your phone. Strengthening the cellular signal: how to achieve it. Strengthening Connectivity with Apps: Pros and Cons
Reasons for a weak 3G signal
All cases of weak or uncertain 3G signal reception can be divided into two large groups. The first and most obvious is the user's distance from the base station (tower) of the cellular operator. The second case is a decrease in the quality of communication inside the premises.
Most often, this problem arises outside cities: in rural areas, in summer cottages and in other places located on the border of 3G coverage. In addition to the distance to the tower, the landscape also plays a negative role: elevation differences, forests and other obstacles reduce the quality of the signal, so that it reaches the user in a significantly weakened form.
In turn, the line of sight of the base station or long flat areas of the landscape are factors favorable for the propagation of radio waves. For example, a forest belt reduces the signal quality, but the presence of a lake, river or field behind it is much preferable to a continuous forest extending all the way to the tower itself.
Reinforced concrete structures and walls, ceilings and even window panes have an extremely negative effect on signal strength. As a result, even in the city center, the connection can easily weaken or completely disappear if you go down to the underground parking or enter an office building. Even if on the street mobile devices pick up 3G perfectly and show all five sticks, the quality of communication in buildings and premises may turn out to be unsatisfactory.
In all these cases, additional signal amplification is required to ensure a stable connection and increase the speed of the Internet. It is important to remember only one thing: in order to amplify the signal, it must be present at least at a minimum level in the planned installation site of the antenna. It is impossible to amplify a signal that is not there, and you need to start preparing for strengthening communication by looking for a place with the most reliable reception.
Frequencies and standards of 3G communication
Before you start strengthening your mobile connection, you need to understand which signal you plan to amplify. All radio equipment - from simple antennas to repeaters and boosters - is designed for specific frequency ranges. Some devices support more bands, others less. There is usually no need to amplify all existing radio frequencies: it is unreasonably expensive and simply unnecessary. It is much more efficient to find out exactly which frequency ranges you need to work. This will allow you not to buy universal expensive equipment and limit yourself to specialized devices that are suitable specifically for your case.
The vast majority of 3G base stations in Russia operate in the 2100 MHz frequency range. The 3G standard corresponding to this band is commonly referred to as UMTS-2100. Both voice communications and mobile Internet are transmitted over 3G networks, so amplification of the frequency range of 2100 MHz is most often the best solution.
Since modern smartphones automatically select the preferred communication standard, in situations of uncertain reception of the 3G signal, they often "jump" between 2G and 3G modes. This behavior leads to interruptions in voice communication and unstable Internet operation. As a rule, you can prohibit switching on the phone by manually selecting one specific standard, but this is associated with additional inconveniences. For example, choosing a high-quality GSM (2G), you deprive yourself of 3G Internet, and vice versa, choosing an unstable 3G, you run the risk of interruptions in calls.
Installation of the amplification system allows you to solve all these problems at once and ensures reliable operation of both voice communication and 3G Internet.
Ways to enhance 3G signal
Depending on whether you want to improve the quality of only 3G Internet or you also need to strengthen voice communication, different approaches are used.
When a 3G connection is used only for Internet access, the best solution is to install an external antenna connected to a WiFi router or modem. This is the most economical and simple option that does not require the purchase of expensive amplifiers and is ideal for a summer cottage or a country house.
However, this method has a number of significant limitations. Firstly, the router and modem provide access to the Internet for smartphones, tablets and computers, but do not enhance the voice communication itself. Thus, if your location has problems with voice communication too, installing a router will not solve them in any way.
Secondly, a separate SIM card is required for modems and routers. Using a modem, you can connect one device with a USB port to the mobile Internet; using a router, you can organize a WiFi network to connect several wireless devices. However, a third-party person who comes from the street will not be able to connect from a smartphone to their operator's 3G Internet: you will first have to provide him with WiFi access.
When you need to provide access to 3G Internet directly from mobile devices or improve the quality of voice communication, you cannot avoid installing an amplification system with a repeater and an internal antenna.
We'll take a closer look at both methods below.
Amplification with router / modem and external antenna
To boost 3G internet, all you have to do is install an external antenna and connect it to a compatible router or modem. The antenna is placed at the point of the most reliable signal reception, preferably in the line of sight of the base station. For suburban areas, this is a roof of a house or a special mast. In the city, it is enough to take the antenna out into the street: it can be fixed on the balcony or on the outer wall of the building.
The antenna itself amplifies the signal and transmits it over a wire to a router or modem. Coaxial cables such as or are used to connect devices. Also in our online store you can purchase with soldered connectors. It is desirable that the cable length does not exceed 5-10 meters. For connecting antennas, N-type or SMA connectors are most often used.
3G routers have a slot for a SIM card and, as a rule, do not differ much from ordinary home routers for wired Internet in configuration. Most 3G routers on the market today support WiFi and allow you to set up a wireless LAN. We recommend our customers a 3G / 4G router, which has established itself as a reliable and inexpensive solution for home and office.

A more budget-friendly option is a set of a regular home router with a USB port and a compatible 3G modem. After connecting to the router, the modem is configured automatically and does not require user intervention. In the store GSM-Repeaters.RU you can buy kits tested for compatibility, for example,.
In the case of using a modem, special adapters are added to the circuit -.
Pigtails - adapters for connecting antennas to modems with CRC9 (left) and TS9 (right) connectors
Selecting and installing an external antenna
The cellular signal is vertically polarized, and if the antenna is incorrectly positioned, the quality of the connection will be severely affected. As a rule, a polarization indicator (usually an arrow) is placed on the antenna body, according to which it should be positioned in space. In the absence of an arrow, the name of the antenna can serve as a polarization indicator (the inscription must be readable).
For mounting it is best to use which will simplify further alignment and tuning of the antenna. The antenna itself should be directed towards the base station of the cellular operator. You can find out which operators are working in your location using our website.
You can determine the exact location of the nearest tower by installing the OpenSignal or Netmonitor application on your smartphone. Also, some modems, for example, are able to show the signal level in decibels.
Huawei e3372 web interface allows you to view the current signal level in decibels (dBm)
OpenSignal and Netmonitor applications
OpenSignal and Netmonitor are smartphone apps that allow you to view the current signal strength in decibels (dB) and quickly locate the nearest base station. The data on the towers of cellular operators is updated by the users themselves, so that the database is always up to date. OpenSignal is available for Android and iOS operating systems, Netmonitor for Android only.
Signal strength is measured in decibels: the closer the indicator is to 0, the better the connection. For example, -50 dB means a strong signal, and -110 dB means a very weak signal.
OpenSignal has a user-friendly interface and automatically shows the direction of a nearby base station using a compass. The Netmonitor application contains more settings and is intended for advanced users. Both OpenSignal and Netmonitor have a mode for displaying base stations on Google Maps.

We recommend using OpenSignal and Netmonitor for signal strength detection and antenna alignment. Knowing the signal strength in decibels and the location of the tower, it is easier and avoids mistakes when installing and configuring it.
Amplification with a repeater
Often, active amplification of the signal is required by means of a special device - a repeater. The fact is that the amplification of 3G Internet described above using a router and an external antenna is convenient, but not universal. In particular, this option is not suitable for people who need to strengthen voice communication, as well as in cases where it is necessary to provide access to a 3G connection to all nearby users. In addition, the antenna gain may not be sufficient for stable operation when the original signal is very weak.
In these cases, it is necessary to install an amplification system with a repeater. The principle of operation of such a system is quite simple: an external antenna picks up the signal and transmits it through a cable to a repeater, which amplifies it. The amplified signal is transmitted to an indoor antenna, which propagates it throughout the room. The outgoing stream is amplified in the same way: the signal from the subscriber goes to the internal antenna, amplified by the repeater, transmitted to the external antenna and radiated towards the base station.
The coverage area of a repeater directly depends on its power. For domestic use, in most cases, a 50 mW repeater with a gain of 65 dB is sufficient. An excellent solution in terms of price-quality ratio is a repeater from a well-known domestic manufacturer. More powerful devices such as (75 dB, 200 mW) or (80 dB, 500 mW) are used to cover a large house and / or when the input signal is weak.
Repeater Baltic Signal BS-3G-65 with a frequency range of 2100 MHz and a gain of 65 dB
Repeaters also differ in the supported frequency ranges. To amplify 3G, you just need to purchase an amplifier with support for the 2100 MHz band, but in some cases it makes sense to think about buying a multi-band repeater.
For example, using a repeater with 900 and 2100 MHz frequency bands will simultaneously improve GSM (2G) and 3G, while the dual-band 2100 and 2600 MHz model will provide 3G and 4G support. The most expensive repeaters allow you to simultaneously strengthen all used cellular standards. The consultants of our store will be happy to help you choose the right repeater model for you.

Installation example for Nika-3 ceiling antenna
For all their versatility, repeaters also have several limitations. The main one is due to the fact that the external antenna is directed to the tower of a specific cellular operator, and if the towers of other operators are in the opposite direction, their signal will not be amplified. In such a situation, to amplify the signal of several operators, you will have to install several directional antennas connected to the repeater through a splitter.
The second limitation is related to the "side effects" of analog gain. The radio signal always contains a certain percentage of interference, which is also amplified by the repeater. With a weak signal, the proportion of interference can be significant, which will lead to a noisy broadcast at the output. Strengthening will still occur, but the quality and speed of communication may turn out to be lower than originally predicted.
Conclusion
Let's summarize and briefly talk about the amplification of a 3G signal:
- It is impossible to amplify a signal that does not exist. To amplify any signal, it is required that it be captured by technology.
- The main reasons for a weak cellular signal are remoteness from the base station and various obstacles in the path of the radio wave.
- In Russia, 3G communication in the overwhelming majority of cases operates in the 2100 MHz range. All 3G amplification equipment must support this frequency range.
- Only mobile internet or mobile internet with voice communication can be strengthened. To amplify only the Internet, an external antenna and a 3G router or modem are enough. To also strengthen 3G voice communications, you will need a repeater amplification system.
- The external antenna must be directed towards the tower of the cellular operator. To find out the location of the tower, use the OpenSignal and Netmonitor smartphone apps. When installing the antenna, observe its polarization.
- Antennas are connected to devices using special connectors. To connect to a repeater, an N-type connector is used, to a router - SMA, to modems - CRC9 / TS9. To connect the antenna to the modem, you will also need a special adapter - a pigtail.
- The 3G repeater acts as an amplifier for the signal from the external antenna and transmits the amplified signal to the indoor antenna located in the room.
- Repeaters are single-band and multi-band. To enhance 3G communication, a single-band repeater supporting the UMTS-2100 standard is sufficient. Multi-band repeaters allow you to simultaneously strengthen several communication standards and create a foundation for the future (for example, provide support for 4G).
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 in 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 influenced 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 holiday or prefer to purchase a plot with coverage. But there is also another way out. You can not give up on your favorite remote area and spend a lot of time on it by installing specialized equipment that can strengthen the network signal - an amplifier for a cellular communication signal and the Internet for a summer residence. This mobile communication 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 bad coverage forever, you need to install special equipment in your country house. Its work does not depend on a particular operator. Whatever mobile company a person uses, the signal will be improved. The quality of the signal amplified by the instrument is not affected by the frequency and standards used.
At the heart of the action of the cellular amplifier for giving is a signal amplifier. An antenna picks up 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 the range.
The principle of operation 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 device 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 the quality of the received connection. The most practical place for fixing the device is the facade of the building. The distance from the external to the internal antenna must 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 in the form of 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 a high-quality telephone connection.
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 Guides Appendix;
Availability of warranty repair services from the manufacturer.
Compliance with these criteria ensures the fulfillment of the price = quality ratio and gives a guarantee of 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. Having invested 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 configuration 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 without affecting its performance.
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 antennas for the successful operation of the repeater.
After installation, the operation of the signal 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 operation of a repeater for a summer residence or a country house. We hope that the collected information turned out to be useful in 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.
Mobile communication is an integral part of our life, leaving it far behind. Thanks to her, we can always be in touch, and also have access to the Internet. Nevertheless, there are situations when the coverage of the network is not good enough, which in turn negatively affects the quality of voice calls and the speed of mobile Internet. This problem was actualized by the massive introduction of 4G, the signal of which is not good in all places.
If you have a poor quality of cellular signal coverage at home or in the country, then it is quite possible to solve this problem, although this will take money and time.
Feasibility of the process
Before purchasing and installing equipment, contact the operator.
If the signal quality of the mobile network is poor, call the operator and report the problem. If your neighbors are also faced with this, then let them turn to the operator. The more applications, the more chances that your problem will be solved by the specialists of the mobile operator for their corporate funds.
For its part, the operator can solve the problem with coverage in two ways: by installing a new base station or installing additional modules on an existing one.
In the case when the operator, for certain reasons, cannot solve the problem with the coverage, this must be solved on his own. Before doing this, you need to calculate everything.
If the coverage of your mobile operator is of poor quality, can you give preference to another? Today, fortunately, the choice of mobile operators is sufficient. When this option is not suitable, and you absolutely need to organize high-quality and reliable coverage - let's get down to action!
Equipment and scope of work
You probably know that cellular communication is divided into 3 types (generations): GSM (2G), 3G and 4G. Each of them works in a certain frequency range. Depending on the required amplification of the type of network, it will be necessary to select equipment.
It is impossible to amplify the signal of several generations of networks with one set of equipment. To amplify the signal, each generation of the network needs its own set of equipment.
However, in most cases only one network generation is needed to amplify the signal, but which one? To complicate matters, each of them has its own advantages, but, nevertheless, let's try to come to a common denominator.
Network
First, study the coverage of the network around. If you receive a signal from a base station with 3G or 4G, then it is best to focus on these generations, since it is the latest and also gives you the ability to access high-speed mobile Internet. The main thing is that all devices support this type of communication.
Tasks
The generation of the network must also be chosen from the tasks set. If you need reliable coverage for making voice calls, and you don't need the Internet, then focus on the GSM network - it's simple and practical.
Subscriber device support
The only caveat is that everyone must have devices that support the selected network type. If GSM is supported by absolutely all mobile phones and smartphones, then third and fourth generation networks are far from all. In other words, if you want to implement a 4G network, all households will need to purchase devices with the appropriate network support, which are by no means cheap.
In a word, it's up to you to decide. It is better to choose a 4G network, as it provides a high-quality connection and at the same time high-speed Internet access. When the planets have converged and your whole family has devices with 3G support, then, by the will of fate, you should choose this network. If you don't bother with all this - take GSM.
What equipment is needed:
- External antenna (directed to the base station to receive the signal);
- Repeater (a device that amplifies the signal and transmits it to the internal antenna);
- Indoor antenna (provides signal propagation indoors);
- 5D / FB cable (cable for connecting an external antenna to the repeater);
- N111 / 5D connector (cable plug).
Be sure to find out on what frequencies your chosen network works, this is necessary in order to choose the right equipment. Also check with the operator where the nearby base station is, or determine it using special mobile programs. In general, the antenna is installed where there is the best network signal on the phone.
If you do not have certain skills and knowledge in this matter, then it is better to entrust the selection and installation to professionals.
Mounting
First you need to strengthen the antenna, depending on its type, and installation will be carried out. Fastening is done with anchors.
As mentioned earlier, you need to find the side with the best signal. It is in that direction that the antenna will be directed. You can mount the antenna on a wall or. In addition, if necessary, you can even build a metal tower on which the antenna will be attached - this is a good solution for country and cottage settlements.
The next stage of installation is cable laying. To do this, we make a hole in the wall and connect the cable to an external antenna. We lay the inner part of the cable indoors to the location of the repeater. To attach the lugs to the ends of the cable, it is better to use the services of a master in the store.
Then we proceed to the installation of the repeater. It is attached to the wall with dowel-nails, and if it is a simple antenna, then it is placed on the shelf. Next, the internal and external antennas are connected to the repeater. After that, we connect the repeater to the power supply, configure it and be content with high-quality network coverage.
When choosing an installation site, before starting all work, draw up a scheme for installing the equipment. Be sure to have a separate outlet near the repeater, and take this into account when drawing up a diagram. The repeater should be located in the center of the area where you want to improve the signal.
This video will help you to get acquainted with the installation procedure and the device for signal amplification:
Do I need to purchase an expensive gadget when it is possible to get by with a device assembled from improvised means?
Those who have at least an initial level of knowledge in the field of cellular communications will be able to cope on their own. This requires accessories and tools, as well as a diagram of the device.
And you can assemble the simplest cellular amplifier on your own. What will be required for this will be discussed below.
Antennas to enhance cellular communication
They are one of the simplest devices to achieve a high-quality signal at any facility.
There are two main groups of antennas:
- External;
- Internal.
The former are usually installed on the roof of a building and are capable of providing coverage over large areas. The antenna transmits the signal received from the base station through the cable to the amplifier. This guarantees good communication quality even in areas where it was previously impossible.
What elements does the signal amplification system consist of?
It is possible to provide reliable communication in hard-to-reach places for a radio signal, but this will require special equipment. Various devices assembled into a single system allow achieving high signal quality and forgetting about its sudden loss forever. It is often referred to as a cellular booster. However, in reality it is a complex consisting of the following elements:
- Repeater or two-way amplifier, which is an intermediate link;
- External and internal antennas that pick up the signal of the station and distribute it indoors;
- Power divider or wire splitter;
- N-connectors;
- Coaxial cable with a resistance of 50 ohms.
All devices included in the system are divided into two groups:
- Active;
- Passive.
The first includes devices that require connection to a power source - a repeater, connectors. Antennas, a splitter and a cable are called passive. Each system is designed for a specific object and therefore may have a different number of amplifiers and internal antennas. The best option is considered one in which a cable of the minimum length is used, since each extra meter of it is a loss in signal quality. This must be taken into account when assembling a cellular signal amplifier with your own hands.
Since all the elements are interconnected, it is recommended to install the equipment before finishing, so as not to spoil the interior.
How the repeater works
Equipment of this class is in some way a repeater. It processes the incoming signals and directs them to the base station tower, if it is an outgoing call. When a subscriber is dialed, the repeater performs the same function, only communication is carried out with the user's gadget.
Watching the video, the simplest way to amplify the signal:
Signals are received and transmitted by antennas. The simplest cellular signal amplifier can be assembled by hand. The outdoor antenna receives or sends it to the station, while the indoor antenna is responsible for expanding the indoor coverage area.
How to make a cellular amplifier with your own hands
The use of such a device allows you to achieve high-quality communication in almost any corner of the object. A repeater is especially needed in areas with poor signal or where it is not available. The advantages of using the system include such features as:
- Strengthening the signal in places where mobile communication interruptions are frequent;
- Elimination of interference;
- Improving the clarity of the message;
- Reducing radiation levels;
- Longer phone battery life.
But since such equipment is not cheap, many decide to make it on their own.
We watch the video, the stages of manufacturing with our own hands:
In order to assemble a cellular amplifier on your own, you will need components that need to be connected into a single system. How to do this will be discussed below.
What you need to build
If you decide to make the simplest device, namely an antenna, then you will need:
- Wire, but not copper (length 30-40 cm);
- Connecting block;
- Cable (up to 10 m);
- Fasteners (for mounting connection blocks);
- Polymer pipe (20 cm);
- Plastic.
Since in the process of work it will be necessary to connect individual elements, it is worth having electrical tape at hand. After all the components are found and prepared, you can start assembling the cellular signal amplifier with your own hands.
A piece of wire must be bent in the middle by 90 °, so that you end up with a rhombus. To do this, retreat from the center 9 cm in both directions. Then, at the point of the mark, the wire is bent again at the same angle. As a result of the manipulations performed, you get a rhombus. The ends are bent inward and the block is connected to them. Install it so that in the future you can make a connection through it. To do this, cut along one side of the polymer pipe and, on the contrary, make a hole.
Watching the video, making an amplifier from cans:
After the antenna assembly stage has been passed, they begin to connect the coaxial cable. At one of its ends, the outer insulation is removed and the outer and inner conductors are connected to the contacts of the junction block. As a result, the cable becomes an extension of the antenna.
After that, it remains to install the device on the roof of the house or attach it to a pole and direct it towards the base station of the cellular operator. The last step in making a simple amplifier with your own hands is to connect the other end of the cable to a plastic plate. And you can start testing.
If everything was done correctly, then, as soon as you bring your mobile phone to the amplifier, the signal indicator will increase by 2 or 3 divisions.
Choosing a place to install the repeater
But it is not enough just to assemble a cellular amplifier, it is also necessary to correctly install it. The efficiency of such equipment is directly dependent on its location, as well as the antennas included in the system. Therefore, before proceeding with the installation, you must make sure that the signal level is sufficient. The easiest way to find out is by making a call from the phone where the antenna is planned to be installed. You can also determine the signal level by the indicator on the display of the gadget.
Antenna installation
But besides this, there are other restrictions. For example, the place for installing the amplifier should not be closer than a meter to the heating devices.
After the planning of the location of all components has been completed, they begin to lay the coaxial cable. But before turning on the repeater, you need to make sure that all connectors are intact and clean. Do not turn on the device if it is not connected to an external antenna, as it may be damaged. If you need to disconnect the RF cables, be sure to turn off the power.
There are also temperature limits. If for an external antenna it is from -40 to + 50 ° C, then for the repeater itself it is limited only by positive temperatures. In addition, the repeater can only be installed in a heated room.
Remember! An incorrectly assembled system is capable of emitting interference, which affects the operation of nearby stations. Therefore, you should not install it without examining the object and determining the place for placing all the blocks.
Amplifier setup
In order to obtain a stable and sufficient communication signal at a specific facility, it is necessary to correctly perform all commissioning work. They consist in setting the quality of voice messages and excluding self-excitation of the device.
We are watching the video of what to do if the signal is bad, we are watching the solutions:
The first thing to start with is to make sure that all connections are intact. The power adapter and antennas are connected to the high frequency connectors. If power surges occur frequently in the network, then a surge protector must be used.
The next step is to adjust the gain. It must be at least 15 dB. The repeater can be configured manually or automatically. In the first case, the adjustment is carried out using the potentiometer knob and changing the position of the external and internal antennas.
Auto tuning involves setting the gain level so that the maximum output power is obtained. In this case, the device will independently adjust to the traffic of the operator's base station.
A constantly breaking 3G or Wi-Fi connection can greatly ruin the mood of the smartphone owner. Engineers have created many devices and programs to improve the internet signal on your phone.

Programmatic way
Not everyone can afford to buy a phone with enhanced signal reception. Owners of smartphones and tablets powered by MediaTek processors can try to improve the performance of Wi-Fi, 3G and 4G using MTK Engineering Mode. The program must be downloaded for free in the Play Market. Actions after installing the software:
- Go to the Telephony tab, select Band Mode.
- Click on SIM1. Uncheck all the checkboxes in the settings, except for EGSM900, DCS1800, WCDMA-GSM-900. This turns off unused frequencies in Russia. A similar setting is performed for SIM2.
- Next, you need to go to the "Network selection" item and install GSM / WCDMA auto. Then, when the phone is working, the 2G signal will not be lost.
- If you select GSM / WCDMA (WCDMA preferred), the device will try to connect to 3G networks, but GSM interruptions may occur.
Internet Speed Master application using ROOT rights
When the reception of web data on a smartphone slows down, users begin to blame the operator and the chosen tariff plan. The Internet Speed Master application can improve the situation. The user must first root the phone, otherwise the software will not change the system files. Procedure after obtaining root rights on an android:
- Enter the program, grant superuser rights.
- Go to the ApplyPatch tab, restart the smartphone. The signal amplifier will then work.
- If you need to return the old settings, go to the main menu of the program, click Restore.
Many craftsmen are trying to create a 4g signal amplifier for a phone on their own. The effectiveness of a homemade antenna is at the level of the initial ready-made signal amplifiers. To create the device, you will need an antenna from an old radio receiver, copper wire no more than 4 mm thick, a screwdriver, a small washer, and soldering accessories. Procedure:
- The antenna is disassembled at the base.
- Wire is soldered to the washer.
- The washer is carefully screwed back to the base of the antenna.
- Some masters advise making a foil reflector for additional signal amplification. You can take a sheet of cardboard as a base for the reflector. You need to glue the foil to it. For convenience, you can purchase foil fiberglass. The reflector is placed behind the antenna.
- The finished amplifier can be connected to a phone or to a 3G modem:
- It is necessary to remove the back cover of the smartphone, find the receiver connector or to connect the antenna. Strip the wire and then connect to the hole.
- If the modem has an input for connecting a third-party antenna, the wire is connected there. In the absence of a connector, the first third of the device is carefully wrapped with wire.
How to strengthen the cellular signal in an apartment or in the country through a repeater
The coverage area of Tele2, MTS, Megafon, Beeline formally includes all settlements in Russia, but in villages far from cities, GSM and 3G do not work so well. You can increase the strength of the incoming cellular signal using a repeater. The device consists of internal and external antennas, a repeater. A homemade passive repeater can be done like this:
- Take 2 wires 4-5 mm thick, make a circle out of them.
- Place homemade antennas on a coaxial cable, solder them at a distance of 5 to 10 cm from each other.
- Connect the cable to the phone or just place the structure next to it.
