Download a program to boost the 3g 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. We determine the range of operating frequencies for voice communications and the Internet. The image above illustrates the entire range of frequencies involved: television 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 higher signal transmission speed and stability of operation with a large number of connections, the UMTS 2100 standard is used.

If you are not an installation organization specializing in installing 3G boosters, you can use a phone with 3G support for a one-time connection. 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 the engineering menu, various information appears, for example, volume level, battery charging, IMEI, wi-fi, phone usage statistics. I don't recommend changing the values.

If you can't find the settings you need, try 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 of best reception. Less is better. Ideally, it is better to place the antenna higher on the roof, but you can find points of reliable reception inside the house.

Equipment selection

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 a circular radiation pattern. It works on the set it and forget it principle. Its advantage lies in the principle of operation. It can catch a signal from several base stations at once, 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 clip.

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

Many people face the problem of low Internet speed via mobile network. How to improve 3G signal on Android? If you are used to using fast home Wi-Fi Internet, and you want the same connection speed anywhere and anytime, we will tell you how you can improve the 3G signal on Android.

How to measure 3G signal level on Android

Thanks to your Android smartphone, you can independently find the best 3G signal in your area.

As you know, cellular smartphone signals are measured in decibels (dB). They are AM/FM radio waves. All cellular devices, including your Android smartphone or tablet, operate within this standard: signal level -50 dB to -120 dB.

50 dB is considered the best signal, and -120 dB is a dead zone where there is no signal.

How to find out how many decibels are on an Android smartphone? This information is available to all users in the mobile device settings. Go to menu Settings -> About the phone -> General information -> Signal strength.

Depending on the smartphone model, sections may have a different name. In any case, you should look for signal strength in the About Phone section.

Remove obstacles

Your smartphone and cell tower are a game of Marco Polo. One shouts “Marco” and the other shouts “Polo”.

If your Android device and the cell tower are in direct line of sight, you will get an amazing 3G signal. But when there are various kinds of objects and obstacles between them, problems with the speed of mobile Internet may arise.

A few simple tips that can help improve the 3G signal on Android:

• Check the quality of the 3G signal outdoors or near a window. It is possible that the thick walls of your home are the reason for the weak 3G signal on Android.
• Avoid high barriers such as trees, hills, mountains, metal structures and multi-story buildings.
• Weather can also affect the quality of the 3G signal, such as rain, snow or thunderstorms.

Find your nearest cell tower

The closer you are to your mobile operator's cell tower, the stronger the 3G signal on Android. Try to find the location of the nearest cell towers on the Internet and check the quality of the 3G signal near it.

Fully charge your smartphone

If your Android device's battery is low, it may not have enough power to find a stronger 3G signal. You should fully charge your smartphone to improve the 3G signal on Android.

Don't block your smartphone's antenna

Before the advent of modern touchscreen smartphones, most phones had large external antennas. Thanks to them, mobile phones received and sent signals to the cell tower.

Modern smartphones also have antennas, but they are hidden inside the case.

If you hold your smartphone in a landscape position (sideways), your hands may block the antenna, thereby reducing the quality of the 3G signal. It is recommended to keep your smartphone in a vertical position to improve the 3G signal on Android.

Also, various accessories and covers for mobile devices can cause a weak 3G signal.

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 blamed the 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 disease of 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 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 can be downloaded from the Play Market. Please note that it is only suitable for devices running on a MediaTek processor. You can find out which processor you have using the CPU-Z program, which you can download, again, from the 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 across the country and handles voice calls very well. 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

Previously, 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 reception.

Nowadays, everyone has modern smartphones, to which, apart from 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 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.

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 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 short 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 measuring approximately 100 by 40 mm, glued to plastic or plywood. It will be better if you have foil-coated PCB.

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 a weak cellular signal on your phone.
