How to improve reception 3 g. How to strengthen the cellular signal on your phone with your own hands. Using purchased or homemade antennas to enhance communications

Many users of 3g networks asked questions, for example: "how to amplify the signal of a 3g modem?" In this article I would like to answer this question.

First you need to understand for what reasons your Internet speed is very low. The problems may be different, but in fact everything depends on the signal level.

Due to this network data transmission operates at frequencies of about 2 GHz, ideally the modem should be directed to the base station and be within its range of sight. In this case, the speed will be maximum.

The situation in the urban area.

If you live in a city, then, of course, the line of sight of the station is rare, and there are various buildings in the way. As a result, the signal is reflected and refracted from them, and only then reaches your modem. The result is a loss of quality and speed.

The situation in the countryside.

You might think that due to the fact that in such conditions there is no multi-storey buildings, the signal level must be very high. But no. In such a situation, another problem arises. The villages are either absent or located very far away. As a result low speed or its complete absence.

Other problems.

Sometimes it happens that the 3G signal is full, and the download speed is rather slow. In this case, thoughts arise: "how to amplify the signal of the 3g modem and is it necessary at all?" The crux of the problem is that there is still such important parameter like network congestion. The more users are simultaneously connected to a station, the slower the data transfer.

How to strengthen the signal of a 3G modem.

There are various options, but not all of them can actually help. The modem can be influenced mechanically or programmatically. But, in fact, all sorts of left-wing programs, supposedly to amplify the signal, will not be able to help. Moreover, you are most likely downloading some kind of virus or something similar.

How to amplify the signal of a 3g modem with your own hands.

The most important thing is that the device is not stuck in the back of the system unit, which stands almost against the wall. In this situation, the signal will be very weak. Therefore, it is advisable that the computer is not against the wall, or connect the modem from the front.

You can amplify the signal using It is about 3-5 meters long. Using it, you can find a place where the speed will be better. It is desirable to place the modem closer to the window. So that the reception rates are the best.

It should be noted that extension cords are different. There are also about 1-2 meters long. The quality also varies greatly. It may turn out that the signal will be even worse, because your cable does not have time to transfer data, or in general, it is USB 1.0. in 1.0. and 2.0. differs tenfold.)

Strengthening the signal of a 3g modem can also be carried out using a special 3G antenna, which is designed specifically for 3G networks, that is, it works in the frequencies we need.

When buying such an antenna, you need to pay your attention to such a parameter as the gain, as well as the radiation pattern. Please note that the larger the ratio, the narrower the chart will be.

If you purchased such a 3G antenna, then you need to install it wisely, and not just like that. You need to direct it to the station, and not somewhere else. Fix it so that the pins are perpendicular to the ground.

If you connect to your modem, then you will sufficiently increase the reception and data transfer rate. The important point is the length of the cable. The longer it is, the worse the reinforcing properties will be. Moreover, only a high quality cable must be used for extension, otherwise there will be little use. If you spent money on an antenna, then you should not spare money on the cable.

Hope, this article helped you, and you were able to solve your problem with internet speed.

Stationary computers can access the Internet using 3G technology most often using an external USB modem. The device can be connected directly to the end device or to a router. In the second case the local network with Internet access is organized via Wi-Fi or Ethernet cable.

Repositioning the receiving device

Since the data is transmitted from the base stations of the operators, the signal level may differ in different places in the room. The main reasons are obstacles in the form of walls and furniture, interference from household appliances... To enhance the signal, the 3G modem is best placed near the window behind which the transmitter tower is located.

The optimal location can be found experimentally by measuring the signal at different points in an apartment or office. To check the speed, special sites are used, for example, the SpeedTest service. For smartphones on Android and iOS, you can measure the speed not only through the browser, but also using mobile applications.

Note! Some sites used for speed testing offer to select a server with which data will be exchanged. For best results and maximum measurement accuracy, mark the nearest server.

How to strengthen a 3G signal with your own hands

If you are using a modem to access the Internet over 3G, you can strengthen the signal strength by using an external antenna or extension cable. Antenna connection is available only if there is a “Pigtail” connector on the 3G modem. USB extenders work according to the following scheme: a modem is connected to one connector, and the other connector is plugged into a USB port on a computer. This allows you to position the 3G modem at a distance from your computer or router, in the area of stable signal reception. There are two types of such devices:

Passive - they work without an amplifier, they are effective with a short cord length.
Active - have a built-in amplifier to avoid signal attenuation. Can be used with long cables.

Important! When choosing a USB extension cable, it is preferable to select models with a ferrite filter that suppresses noise. Usually it is made in the form of a cylinder with a plastic sheath, which is fixed to the cable.

Improving 3G signal on smartphone

On Google Play, you can find special applications to enhance 3G reception on Android, for example:

HSPA + Tweaker;
Signal Booster 3G;
Connection Stabilizer Booster;
Signal Care Free.

The principle of operation of most of these utilities boils down to changing the active base station. The program determines which BS is connected at the moment and tries to find an access point located closer. In the same way, you can strengthen the 3G signal on your tablet if it is equipped with a SIM card slot.

Dense urban development, terrain, power lines and distance from transmission towers greatly affect the quality of signal reception, which can be lost at the most inopportune moment.

And today I want to talk about several ways to enhance cellular communication on the phone with my own hands and how they really help. But before you take any action with your device, you need to make sure it is working properly.

After all, poor reception can be the result of a malfunction of the radio module, unreliable contact with the internal antenna, or a flashed firmware.

It is very easy to make sure that your smartphone is working properly. It is enough to compare his level of acceptance with another, obviously working, not necessarily of the same model.

If it is very different, then, most likely, the mobile phone is faulty and it has a direct road to the repair shop. But there is no need to rush. I had a similar situation with Lenovo 316i, when the level bars on the display constantly disappeared, while other mobile phones worked fine. For some reason, I sinned on a buggy software.

And, of course, I tried to reflash it, but the result did not change. Having studied a considerable number of forums, I was inclined to conclude that the reason for an unimportant reception may be poor contact at the junction of the antenna and the motherboard.

This is a common disease in Chinese gadgets. The next step I decided on was to disassemble it.

And in fact, upon opening the case, I found that the middle spring tab on the board is slightly bent down and does not come into contact with the antenna, which is a flexible ribbon glued to the cover.

Armed with tweezers, I bent it up a little, screwed everything back, put the SIM card and the battery in place, and pressed the power button. After booting the system, all four divisions appeared in the status bar, and this time they did not disappear.

Thus, having the skills and certain knowledge, I myself managed to repair my mobile. But now let's talk about the methods by which you can significantly improve the quality of communication.

A software method for amplifying a cellular signal

This time we will not disassemble anything, but install a special MTK Engineering Mode application on Android, with which we will enter the engineering menu and change some parameters there. It is free and you can download it from the Play Market. Note that it is only suitable for devices powered by the MediaTek processor. You can find out which processor you have using the CPU-Z program, which you can download, again, from the Play Store. So, we click on the shortcut of the program and immediately get into such a menu.

Go to the MTK Settings tab

As a result, on the display we will see such a window with the settings, where we remove all the checkmarks. We leave only

EGSM900;
DCS1800;
WCDMA-GSM-900.

Thus, we turn off unnecessary frequencies that are not used in our country.

We do the same operation with SIM2.

Then we go to the "Network selection" where we select the item GSM only. This is a 2G communication standard that originally appeared in the construction of telecommunication networks.

It has wide coverage across the country and is excellent at handling voice calls. Select this tab if you do not use 3G internet.

After these manipulations, your handset will work longer in time by turning off the scanning of unnecessary frequencies and keep the radio signal more stable, since it will not jump between WCDMA and GSM standards.

Connecting a homemade antenna

Earlier, cell phones had an external radio antenna or a plug under a plug located on the back of the case, into which any piece of wire could be inserted, which significantly increased the reception.

Now everyone has modern smartphones, to which, apart from charging and headphones, nothing else can be connected. But, if you disassemble it, then inside, on the board, you can see a small golden cylindrical connector with a hole in the middle.

It is intended for network diagnostics and is used only in service centers. But, if you insert a small piece (no more than 5 cm) of a thin insulated wire into it, you can observe a noticeable increase in the signal level.

Only in this case it is necessary to comply with some conditions. The wiring should not bend anywhere and touch live parts. It can be neatly laid inside the case, between the battery and the cover.

Again, this method is not suitable for everyone, since most devices are non-separable or do not have such a connector.

Installing the repeater

This option is ideal for use in a country house or in a village, where, as a rule, the quality of communication is poor due to the remoteness of the towers.

Its principle of operation consists in capturing electromagnetic waves, preamplifying them and transmitting them to the user's phone. The system consists of a repeater unit, external and internal antennas. The disadvantage of this equipment is the expensive price of the device, the complexity of installation, settings and a small range. But you can try to build a homemade installation yourself to amplify the signal.

To do this, we need a metal rod, about 50 cm long, a coaxial cable, a piece of foil about 100 by 40 mm in size, glued to plastic or plywood. It will be better if you have a foil-clad textolite.

So, we bend our rod in the shape of a diamond and solder a cable to it, the other end of which we solder to the foil.

An example of connecting a cable to a rod

We install our diamond on the roof of the house or on a post, preferably higher.

Now we check the amplifier. To do this, put the phone close to the plywood and notice how much the signal quality has improved.

Sticker sticker

Often on sale you can find a universal compact antenna amplifier, which is a thin self-adhesive plate with a special geometric pattern made of metal tracks, which, according to the manufacturer, reduce the amount of interference and can significantly enhance the signal where there is practically no cellular connection.

A sticker is glued to the inner surface of the phone, under the battery. But in my opinion, there is no point in buying it. You can just as well put a piece of foil under the battery and the effect will be the same.

Here, with the help of such simple manipulations, you can do it yourself, using inexpensive materials, to strengthen a weak cellular signal on your phone.

P.S. I am attaching a screenshot of my earnings in affiliate programs. And I remind you that everyone, even a beginner, can make money this way! The main thing is to do it correctly, which means to learn from those who are already earning money, that is, from the professionals of the Internet business.

Internet access is necessary for every person for work, study or for their personal needs. The mobile phone does not always pick up the internet. Not everyone knows how to amplify the 3g signal of a smartphone.

In cities where there are a large number of mobile operators, there should be no "dead zones" for the Internet according to prior. In fact, everything is different: a person, moving around the area, periodically gets into them. It has to do with architecture, building material from which houses are built, with metal structures. The reasons for poor Internet connection include the presence of a lot of industrial interference.

To protect the smartphone from mechanical damage, different cases are sold. If there are metal inserts inside the protection, this affects the quality of the received signal 3g and 4g.

When a user leaves the city, a 3g signal amplifier for a smartphone is required, where the internet speed is abrupt or absent.

Almost all people use 3g or 4g internet, which is offered by mobile operators. It provides access to networks anywhere, unlike a wi-fi network. But due to the congestion of the communication lines, the Internet speed drops to the level of 2g. Even if the phone is on a tariff with a good 3g or 4g speed, it guarantees that the speed will not slow down.

Two solutions will help to improve the reception of a smartphone - this is software and with the help of devices purchased or made on their own. Each method has its advantages. At integrated approach by increasing the speed of the Internet connection, the user will achieve the fastest signal possible.

Software settings

Sometimes people are unhappy with the speed of the Internet on mobile phone... Everyone knows that the speed and quality of the Internet connection depend on the operator, the selected tariff and coverage area. But not everyone knows that you can amplify the signal on a smartphone using the InternetSpeedMaster application. The program optimizes phone performance by modifying system files. Strengthening the antenna on a smartphone using the application is easy, but you need to be rooted, if the phone is rooted, then the installation will take 2 minutes.

Program setting for 3g and 4g amplification

How to configure InternetSpeedMaster software to amplify 3G and 4g signal:

log into the application and grant superuser rights;
if the device is rooted, enter ApplyPatch, reboot. The Internet signal booster on the smartphone will work;
if the user does not have superuser rights, enter the ImproveInternetConnection, then reboot the device.

This method does not work on all devices, so it is recommended that you first get root rights in order to surely increase the 3g signal on your smartphone.

If the user wants to return the old settings, it is recommended to enter the menu, press "Restore", confirm his actions by selecting the "OK" button.

Hardware improvement

You can strengthen the cellular signal on your smartphone by purchasing additional devices in specialized stores - a repeater and various types of antennas. Such devices significantly amplify the signal coming from the operator. In this situation, no manipulation of the device files is required.

All devices connected to the Internet 3g or 4g, included in the coverage area of the antenna, increase the download speed. In order to amplify the 3g signal for a smartphone with your own hands in the country or in an apartment, you need to take steps that will enable the operator's signal to reach as quickly as possible.

How to strengthen the signal of a 3G modem - important question among users mobile internet... It occurs quite often due to the long distance to the base station, terrain features, or other factors that negatively affect the quality of signal reception. Various devices such as antennas, amplifiers, repeaters and others can help to enhance the quality of communication. They can be bought ready-made or assembled homemade. The second option will cost much less, but the quality will be approximately the same. Antenna for 3G signal amplification is the ideal device to help improve poor reception and improve connection stability.

The speed of data transfer in a mobile operator's network depends on many different factors.

Basically, these are well-known:

distance to the operator's tower;
relief features. If there are hills and ravines, then the signal quality and speed will decrease;
network congestion. The more it is loaded, the slower the surfing speed on the Web;
various emissions from electronic devices and devices that jam data transmission;
a large number of crossed frequencies on the ground, which also work as jammers;
some peculiarities in the operation of the operator's equipment and other factors.

Important! The 3G mobile standard is capable of transmitting data at a high enough speed for watching movies online, making video calls and other entertainment on the Web. However, if the network is loaded and the data transfer rate is reduced, then it is not always possible to take advantage of all the possibilities of this technology.

Also, an important condition that affects the speed of the Internet is whether the subscriber is on the move or goes online indoors. In motion, the speed is much lower than in statics.

Qualitative indicators of the Network:

Interruption of calls. It is measured as a percentage of the number of successful calls (now operators are fighting to improve performance by hundredths of a percent, in rural areas there are more than average, because the stations are located farther from each other, in the city there are much fewer);
Unnatural voice (“metallic”) or poor hearing;
The loaded network (it is also considered as a percentage of the ratio of call requests to successful calls. There should be no more than 2%, but in fact there are less of them - thousandths of a percent).

How to measure your speed

There are several ways to measure. First, by using one of the online services. You need to go to a similar site and start measuring the speed of data transmission and reception. Secondly, by downloading a special application to your phone or tablet. The principle of operation of both methods is the same, just in the first case you don't have to download anything.

Note! The most popular application and online service for measuring the speed of data exchange is Speedtest.net.

In addition, you can use the following resources:

Internet Speed Meter Lite;
Internet Speed Test;
Simple Speed Test;
Network Monitoring.

Important! The Internet connection speed gauges listed above support all operating systems, such as Android, iOS, etc.

How to find your base station

To find out the base stations of mobile operators, you can also use special applications that help you see the coverage areas or the location of the towers. Common services and applications:

Opensignal.com is a service that helps you determine coverage. Does not display base stations. You can select a specific operator and location of the subscriber;
Netmonitor.ru - a domestic service that determines the nearest towers of mobile operators;
Opensignal is a smartphone application that allows you to view the nearest base stations on a map, as well as wireless transmission points Wi-Fi networks... The service marks the area with poor signal quality, has a compass and checks the speed of the Internet connection;
Netmonitor is a program that is capable of monitoring cellular networks, displaying data on signal quality and keeping records.

Ways to enhance the modem signal

Note! There are two ways to amplify the modem signal - software and hardware.

As for the first, today there is no program with which it would be possible to really improve the quality of the received signal on the phone. There are special applications that allow you to control the quality of communication, that is, they directly transmit data to the user about the level of the received signal. With their help, you can choose a place with the best level of communication. Some programs may automatically switch to a station with more high speed internet connections. On this, the possibilities of the programmatic method are exhausted.

With regard to hardware, these include the following devices that have the ability to improve the signal without interfering with system and software settings:

repeaters;
antennas;
reflectors;
routers.

Note! These devices interfere with electromagnetic waves, thereby actually improving the received signal.

The advantage of hardware signal amplification is the ability to increase the Internet speed for all devices that are connected to the home network.

What is an antenna

There are several types of antennas. They can be both external and internal. By types are divided into:

Kharchenko antenna;
MIMO;
panel;
sector, etc.

Note! Most often, this is an external device, which is used to better pick up the signal when its quality is poor due to the high range to the base station.

Speakers for signal amplification

This is one of the simplest ways to improve signal quality and network speed. In this case, there is no need to purchase or design antennas and amplifiers. Based on user experience, all you need to do is move the speakers closer to the modem itself. In this case, the quality of signal reception increases up to 20%. Not such a big gain, but with a low quality of the connection, it gives good results.

Important! So that the speakers work, and the sound does not bother you, you can turn it off to a minimum.

Copper Wire Amplifier

Perhaps this is the most effective method improving the quality of the connection, but you will have to work a little, since you will need to assemble a special device. The items for assembly can be copper wire and an iron can as an antenna. Device assembly sequence:

You need to purchase a piece of wire 60 cm long.
Open the modem or phone and make a few turns of the wire around the SIM card.
Pull the other end of the wire to the window.
Cut off the lid of the jar so that it takes the shape of a glass. It is she who will work as a communication amplifier.
Tie a wire to the bottom of the can.
Rotate the resulting structure towards the nearest operator base station.

Note! This antenna can improve the quality of the connection by up to 90%.

Gain by network settings

Many subscribers of the mobile Internet do not know that when the quality of the connection in the 3G standard decreases, the modem automatically switches to the reduced standard of the second generation. Its connection speed is very low. To avoid this, when the device does not completely lose 3G signal, you can specify that the downgrade does not occur. To do this, you need to perform the following steps: "Network settings" - "Connection" - change the search mode from automatic to 3G.

USB extension cable

In this case, you need to assemble a kind of analogue of a satellite dish. A CD or any metal surface is suitable as a reflective surface. Extension Cord Assembly Steps:

In the middle of the disk, make a mount for a USB flash drive. Plain scotch tape will do.
Connect one end of the USB cable to your computer and the other to your modem.
Install the disc outside the room. It is advisable to direct the flash drive towards the tower.

External amplifier

Such an external amplifier allows you to connect directly to the modem and improve signal reception. These off-the-shelf devices are sold online or in specialty stores. The choice should be based on the characteristics of the radiation pattern and the antenna gain. It is required to install and point towards the nearest base station.

Repeater

It is a special device for amplifying the Internet signal. This is the most professional device of all. Ideal for a summer cottage, a country house or any remote area where there is at least a minimal signal from the operator.

Note! Allows you to get the highest possible speed, good reception by all devices within the radius of the internal antenna, improve the stability of the connection.

Internal antenna

You can either assemble it yourself or purchase it ready-made. If a device that receives a signal, a modem or a router, has an open connector, then an amplifier or any other antenna can be connected to it to improve the signal quality.

There are several ways to boost your mobile internet signal. Some work with a simple software setup, while others require special devices. The most effective is the use of a repeater and a high-quality external antenna.
