Antenna booster for android. Weak antenna signal on android. How to strengthen the phone signal: causes of a bad signal and a do-it-yourself solution to the problem. Causes of a poor mobile signal: can it be improved

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 with a large number of operators cellular communication, according to prior there should be no "dead zones" for the Internet. In reality, everything is different: a person, moving around the area, periodically gets into them. This is due to architecture, the building material from which houses are built, metal structures. The reasons for poor Internet include the presence of many industrial interference.

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

When the user travels outside the city, a 3g signal booster for a smartphone is required, where the Internet speed is sharp or absent.

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

Two solutions will help improve smartphone reception - this is software and using devices purchased or made independently. Each method has pluses. With an integrated approach to increasing the speed of the Internet connection, the user will achieve the fastest possible signal.

Software settings

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

Configuring the program for amplifying 3g and 4g

How to configure InternetSpeedMaster to boost 3g and 4g signal:

1. enter the application and grant superuser rights;
2. if the device is rooted, enter ApplyPatch, reboot. The Internet signal booster on the smartphone will work;
3. if the user does not have superuser rights, enter 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 restore the old settings, it is recommended to enter the menu, click "Restore", confirm their 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 manipulations with the device files are required.

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

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

In most cases, all rural residents of Russia connect to the Internet using 3G modems. And the farther the village, the worse not only the 3G Internet, but also the usual cellular connection.

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

1. With an antenna.
2. With antennas and amplifiers.
3. With 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, sometimes not.

You need to know exactly in which range the 3G signal of the selected telecom operator is transmitted, and where the boundaries of this signal are. To check the signal level, a regular cellular telephone or spectrum analyzer.

Checking the signal level

Before you strengthen anything, you need to catch something. We determine the range of operating frequencies for voice communication and the Internet. The image above illustrates the full 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 checked is transmitting the Internet. It can be transmitted in UMTS 900 and UMST 2100.

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 with a large number of connections, use the UMTS 2100 standard.

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

How to do this on your phone, look on the Internet. Here are the most common codes.

When we enter engineering menu various information appears, for example, volume level, battery charge, IMEI, wi-fi, phone usage statistics. I do not recommend changing the values.

If you cannot find the settings you need, use another phone. As a result, 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 - this is UMTS 2100, if within 2937-3088 - 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 level of 3G signal reception. Having constantly changing dynamic parameters of the signal level, we are looking for the best reception point. Less is better. Ideally, it is better to put the antenna higher on the roof, but you can find points of reliable reception inside the house.

Equipment selection

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

AP-1900/2700-17 Directional Antenna for Cellular Signal Amplification

A fantastic result is shown by the AO-2000-11 brand antenna - with a high gain = 11 dB and a circular radiation pattern. Works on the principle of set and forget. 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 signal direction.

In almost 80-95% of cases, when a 3G signal is at least somehow caught, it is enough to fasten a 3G repeater amplifier TAU-2000 from Picocell to the antenna, and you will catch 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 lugs of which are crimped in an industrial way or with a special tool.

Ready kits

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

Kits can be of several types:

• without amplifier;
• with amplifier;

Consider kits without amplifiers. The structure of such kits includes an antenna, wire. Conveniently, if you have a modem or router, then the cost of amplifying the 3G / 4G signal will be minimal. A set of wires and an antenna will cost you from 5,000 rubles.

Antennas are selected based on the location, number and distance to the base stations. You can always increase this kit with an amplifier, the final price of the equipment will increase, as well as the quality of the received signal.

You can use any antenna, including those listed when selecting equipment, but it’s better to buy a Huawei E392 modem, although its price starts at 3200 rubles.

Watch a short video of everything stated in the article, if anyone is interested in the subtleties, 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 mobile phone 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 cable for a modem

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

Despite the widespread use of mobile communications, the question is still relevant how to strengthen the signal of the phone, or rather cellular communication, to which it is connected. It doesn't matter if you live in a small village or in a metropolis, the chance that your device will stop receiving a signal is everywhere. Gradually, this problem is solved by operators, new base stations appear, communications are increasing. But what if the problem lies in your phone, and not in the network? Today we decided to figure out what the bad signal level is connected with and whether it can be fixed by hand.

The principle of operation of cellular communication is quite simple: there is an operator’s base station and your phone, a radio frequency channel is organized between them, through which SMS messages are transmitted, calls are made, and Internet data is exchanged. There are several cellular communication standards that differ in signal transmission method and frequency. As a rule, base stations are built on hills in order to provide maximum coverage. However, you can’t get away from the barriers that prevent the passage of the signal. These can be walls, trees, and other obstacles, upon contact with which the signal weakens.

It is clear that in open areas where high-rise buildings do not abound, the coverage area will be higher. For example, for stations operating according to the GSM-900 standard, in this case, the zone is no more than 30,000 kilometers. In urban areas, the figure is reduced to 7 kilometers. Stations with more advanced communication standards in the face of 3G and LTE cover an area half the diameter.

Why do we have a weak phone signal?

Due to the above mentioned barriers, so-called dead zones or holes in the coating can be formed. That is, places where the signal is weak, unstable or completely absent. Where do you most often encounter poor signal strength on your phone:

• places located at a significant distance from the nearest station (there is simply no coverage);
• basements, underground parking, lowlands (the signal is simply unable to penetrate here);
• hills, skyscrapers (often "to rise higher" does not mean the obligatory presence of a signal - above the 12-14th floor there is often no signal at all);
• buildings made of metal structures that do not transmit a signal.

However, obstacles and distance from the station are not always the reason for the lack of a signal. Often the user's phone becomes the cause. You have probably been in situations where a friend has a cellular signal, but you do not. And at the same time, you use the services of one operator. There are cases when different signal levels are observed on two identical phones. There can be many reasons:

• phone in metal case or in a metal case it can catch a net much worse than a plastic device;
• quite often, no matter how surprising it may sound to you, the reason is the “clumsy” firmware of the phone;
• damage to any components as a result of falls, immersion in water, and so on;
• the phone may have a defective antenna from the factory, which is especially sinful for Chinese manufacturers of inexpensive models.

How to strengthen the phone signal with your own hands?

So, let's go over the theory, let's move on to practice. We will analyze several ways to boost a cellular signal, starting with the simplest, ending with quite complex and expensive ones.

Reason for the firmware

It's worth starting with checking the correct operation of the software before trying to get to the insides of the phone. With the deterioration of the communication signal that appears after flashing, hundreds of users are faced, so attention should be focused. We have already written, so we will not repeat ourselves. Firmware is a fairly simple process, but with its own nuances. Most importantly, remember to back up your important files.

If the flashing helped, then we congratulate you, but if the phone still does not catch the network well, then proceed to the next step.

Poor signal reception due to damage to the phone

As already noted, often the phone does not pick up a signal well after it accidentally fell on a tile or plunged into the sea. In this case, the average user has no choice but to go to a service center. Modern phones- quite complex devices, therefore it is not possible for most to identify the source of the problem on their own. It is likely that specialists will detect damage and perform the necessary work so that your phone can again cope with network searches without any problems.

How to boost your phone signal

In most cases, the cause of a weak cellular signal lies in the defect of the antenna, which, in fact, is responsible for this function. Often, owners of inexpensive smartphones from the Middle Kingdom are faced with the fact that the manufacturer cheated a little by loosely connecting the antenna to the device's motherboard. You can fix the mistake yourself, but you need to understand at least a little how the phone works. Otherwise, please contact service center with a description of the problem.

1. now smartphones are represented by a very different design, and therefore they are disassembled in different ways; it is easiest to get to the insides of a phone with a removable cover and battery, it is more difficult when the smartphone is not collapsible;

Take your time. Before starting disassembly, find a video or text material on the Internet that will show and tell how your particular device is disassembled, what you should pay attention to.

Please also note: after disassembling the smartphone, you lose the warranty.

1. as a rule, the antenna is hidden in the lower or upper part of the case, represented by small copper strips (again, for the location of the antenna specifically in your model, see the relevant materials);
2. after you get to the board, you will find several spring contacts, which should fit snugly against the cable located on the back of the structure;
3. if the spring contacts of the motherboard do not adhere well to the cable, carefully correct them, armed, for example, with tweezers;
4. assemble the phone and enjoy a good network signal.

We connect a homemade antenna to the phone to amplify the signal

The methods discussed above only work if the problem lies in your phone. But, as we noted at the beginning of the material, the cause of a bad signal can be various kinds of obstacles or a significant distance from the station. In this case, you can try to strengthen the antenna of our device with just a piece of wire.

Just note that the method is not suitable for all phones. The fact is that for its implementation you will need a special diagnostic port, which is difficult to get to in a modern non-separable smartphone (in a number of models you can’t find it at all). It looks like a small round connector of golden color.

take a small piece of thin insulated wire;

insert into the connector;

lay it so that it does not interfere with other components and closing the lid.

Everything, as practice shows, the signal of the phone network is amplified to a large extent. Isn't it surprising?!

Some users inserted a piece of wire into the 3.5 mm port (for headphones). Sometimes that works too.

Sticker sticker or foil to boost phone signal

In the vastness of foreign online stores, it will not be difficult to find a bunch of different devices for signal amplification. Among them, a small sticker-sticker is popular, which is a few metal tracks, which, according to the manufacturer, allow you to get rid of interference.

Similar stripes can be seen in some smartphones by default, so the "magic" properties of the sticker have the right to life.

However, to achieve a slight improvement in the signal, according to a considerable number of users, a piece of ordinary foil will help. It is located under the cover of the phone, closer to the antenna. The method is simple, so you can try.

Strengthening communication with a repeater

In some cases, when the signal cannot be amplified by any of the methods (too thick walls of the room, remoteness from the base station), they resort to the use of special antennas or repeaters. Such devices can greatly amplify the signal, but their cost often scares off a potential buyer.

Where to buy cheap?

You can build something similar with your own hands, but often it does not amplify the signal at all or does it very, very badly.

For example, some use the following method:

1. we take a metal rod (50 cm is enough), a coaxial cable, a piece of foil (about 10x4 cm) and plywood or plastic;
2. we bend the metal rod so that we get a diamond-shaped design;
3. glue the foil to the plywood;
4. we connect the metal rhombus and the foil using a coaxial cable (solder);
5. the end, on which the rhombus turned out, is raised higher, the other, with foil, is left below;
6. We bring the phone to the foil to check the signal quality.

It will probably be necessary to find the most suitable place for the resulting structure to catch the signal.

It is clear that such an amplifier is unlikely to provide communication to a large company that was not lucky enough to have an office in an area without network coverage. Here you will have to seek help from specialists. Today, many companies provide such services, and not only will they offer modern equipment, but they will also install it. By the way, you should not save on specialists - for installation, workers use special devices that help determine the most suitable place, select frequencies, and so on. For an ordinary user, of course, it will be difficult to cope with such a task.

The positive thing is that engineers have already come up with several options for getting rid of such inconveniences. The disadvantages include the requirements for additional financial investments and the complexity of setting up communication amplification systems. However, let's not get ahead of ourselves and tell about all this in order.

Mobile phone signal booster

The simplest option to avoid a weak signal is to install the amplifier not on a certain area or building, but on a specific phone. Similar antenna amplifiers look like stickers and are glued inside the body of the device or on its back cover.

Amplification of the signal occurs due to a change in the radiation pattern of the phone's own antenna and an increase in the total induction of the two antennas.

The disadvantage of this method can be considered a change in the circular reception of a mobile phone to a narrowly focused one. Simply put, the signal will improve significantly when you point the phone towards the tower of the mobile operator. In other cases, the signal quality, on the contrary, will fall. How effective is such a signal amplifier mobile communications for you personally, it is worth, of course, to decide on your own.

The next way to enhance the quality of communication is a point-to-point mobile signal amplifier with a small coverage radius. This option is suitable for cases where the strong signal zone is only a few meters from your workplace.

Despite the widespread use of mobile communications, the question of how to strengthen the signal of the phone, or rather the cellular communication to which it is connected, is still relevant. Whether you live in a small village,...
