Download firmware to strengthen the communication signal. Weak antenna signal on Android. How to strengthen a phone signal: reasons for a bad signal and solving the problem yourself

In villages, until now, in most cases there is no dedicated Internet line. It happens that the Internet can be connected via an ADSL line if you have a connected landline phone.

In most cases, all Russian villagers connect to the Internet using 3G modems. And the further the village is, the worse not only the 3G Internet, but also regular cellular communications.

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

1. Using an antenna.
2. Using an antenna and amplifiers.
3. Using multiple antennas and multiple amplifiers.

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

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

Checking the signal level

Before you can strengthen anything, you need to catch something. Determining the operating frequency range voice communication and the Internet. The image above illustrates the full range of frequencies involved: TV signal, wi-fi, DECT, GSM, LTE, etc. It is important to understand in what range the base station at the point being tested transmits the Internet. It can be transmitted in the UMTS 900 and UMST 2100 standard.

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

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

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

How to do this on your phone, look on the Internet. I will give the most common codes.

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

Can't find required parameters, use another phone. Finally, you need to determine the Rx CH parameter. The first value surrounded by a red frame shows in which range the signal is received. If the value is within 10562-10838, it is UMTS 2100, if within 2937-3088, it is UMTS 900. Having determined the operating range, you can accurately select a 3G signal amplifier, for example, high-quality Picocell 900 or Picocell 2000.

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

Selection of equipment

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

A fantastic result is shown by the AO-2000-11 antenna - with a high gain = 11 dB and pie chart direction. It works on the set it and forget it principle. Its advantage lies in the principle of operation. She can catch a signal from several at once base stations, which significantly affects the speed of the Internet. No need to look for the direction of the signal.

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

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

Ready-made kits

When you know exactly what type of amplifier you need and whether you need it at all, you can start purchasing equipment. If there are no retail outlets in your city, buy from online stores or directly from the equipment manufacturer.

Kits can be of several types:

• without amplifier;
• with amplifier;

Let's look at kits without amplifiers. Such kits include an antenna and wire. Conveniently, if you have a modem or router, then the cost of strengthening the 3G/4G signal will be minimal. A set of wire and antenna will cost you from 5,000 rubles.

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

You can use any antenna, including those given when selecting equipment, but it is better to buy a modem Huawei E392, although its price starts from 3,200 rubles.

Watch a short video of everything outlined in the article; if anyone is interested in the intricacies, go to the site indicated in the video.

And finally, I’ll share an observation: buy an antenna and equipment in specialized stores, and not in cellular communication stores; what they sell there does not work.

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

Ask questions if anything is unclear. Good luck with your shopping.

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

And today I want to talk about several ways to strengthen cellular communication on your phone with your own hands and how much they really help. But before you perform any actions with your device, you need to make sure that it is working properly.

After all, poor reception may be the result of a faulty radio module, unreliable contact with the internal antenna, or a broken firmware.

Making sure that your smartphone is working is very simple. It is enough to compare its reception level with another one that is obviously working, not necessarily of the same model.

If it is very different, then most likely the mobile phone is faulty and it needs a direct trip to a 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 was guilty of 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 cause of poor reception may be poor contact at the junction of the antenna and the motherboard.

This is a common illness Chinese gadgets. The next step I decided to take was disassembling it.

And in fact, upon opening the case, I discovered that the middle spring tongue on the board was slightly bent down and did not contact the antenna, which was a flexible cable glued to the cover.

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

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

Software method for boosting cellular signal

This time we won’t disassemble anything, but install it on Android special application MTK Engineering Mode, 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. Please note that it is only suitable for devices running on the MediaTek processor. You can find out which processor you have using the CPU-Z program, which you can download, again, from Play Market. So, click on the program shortcut and immediately find yourself in such a menu.

Go to the MTK Settings tab

As a result, we will see on the display this window with settings, where we uncheck all the boxes. We leave only

• EGSM900;
• DCS1800;
• WCDMA-GSM-900.

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

We perform the same operation with SIM2.

Then go to “Select a network” where we select the GSM only item. This is the 2G communication standard, which originally appeared during the construction of telecommunication networks.

It has wide coverage throughout the country and does an excellent job of voice calls. Select this tab if you do not use 3G Internet.

After these manipulations, your handset will work longer by disabling 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 connector under a plug located on the back of the case, into which any piece of wire could be plugged, which significantly enhanced the reception.

Now everyone modern smartphones, to which, except for charging and headphones, you can’t connect anything else. But, if you take it apart, 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 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 or touch live parts. You can carefully lay it inside the case, between battery and a lid.

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

Repeater installation

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

Its operating principle is to capture electromagnetic waves, pre-amplify them and transmit them to the user’s phone. The system consists of a block - repeater, external and internal antennas. Minus of this equipment is expensive price on the device, complexity of installation, settings and small range. But you can try to build a homemade installation to amplify the signal yourself.

For this we need a metal rod about 50 cm long, coaxial cable, a piece of foil measuring approximately 100 by 40 mm, glued to plastic or plywood. It will be better if you have foil-coated textolite.

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

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

Now let's check the amplifier. To do this, we place 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 of metal tracks, which, according to the manufacturer, reduces the amount of interference and allows you to significantly strengthen the signal where there is practically no cellular communication.

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

Now, with the help of such simple manipulations, you can use your own hands, using inexpensive materials, to strengthen the weak cellular signal on your phone.

Hello, dear readers!

Most owners various gadgets based on Android systems dissatisfied with the snail's Internet speed of their devices.

However, today there are certain programs, with which you can significantly increase your connection speed.

Today I would like to tell you about the three most popular and effective of them.

Internet Speed ​​Master

Internet Speed ​​Master is a program for improving Internet speed on Android devices. It was created by the developers of Nez Droid. Trial version You can download the programs for free and easily on the developers’ website.

The software optimizes the settings of the database transfer system by changing certain system files. The program supports absolutely all versions of Android, as well as firmware options. Among them there are those in which the speed problem has already been solved, which is why it is impossible to say with complete confidence whether the application will be able to speed up the Internet on your tablet or smartphone.

How to speed up your connection using Internet Speed ​​Master?

The scheme is as follows:

1. Open the program.
2. During the first launch it will ask root access. Leave it to her.
3. Subject to availability root rights Click “Apply Patch”, as a result the device should reboot.
4. After the device turns on, you can verify the effectiveness of the actions taken.

If you do not have root, click “Improve Internet Connection” and reboot your device. From my own experience, I can say that this “thing” does not work on all devices, so it’s better to take the trouble to acquire root rights. Thanks to them, you can speed up the Internet on your device without any unwanted consequences.

To return to the old settings, just click on “Restore” in the main menu and click on “OK”, thereby confirming that the system files have been restored.

So that you don’t blame me later, I’ll repeat it again, Internet Speed ​​Master will not help you if your firmware has already increased the Internet speed.

Signal Booster 2X

The second acceleration program that I would like to tell you about is called Signal Booster 2X. It is much easier to install than the one I wrote about above. Main features of this application:

• Simply click on the “signal booster” button and the application will be in automatic mode reboot Wi-Fi and restore the signal.
• If the signal at your location is not strong enough, the system will immediately notify you about this and suggest a number of actions to improve it.
• Intuitive interface.

While in the zone weak coverage a 2X signal amplification system will come in handy. Its presence will improve the performance of your device in WI-FI networks/ LTE/4G/3G.

Software Speed ​​3G Modem

This application was created to increase the connection speed of a 3g modem with the World Wide Web. The program allows you to speed up your connection several times by optimizing bandwidth.

Even though this application developed to solve problems with 3g Internet, it can improve the quality of the connection and when the usual way connections. The program under discussion functions and sets up the connection automatically.

You need to connect to the network and launch the application. The program menu is designed in Russian. Click on “increase speed” and move the slider to the “fast” mark.

That's all I wanted to tell you. Use my tips and enjoy all the delights World Wide Web.
