Weak antenna signal on the android. How to strengthen the signal of the phone: the causes of a bad signal and the solution of the problem with their own hands

Despite widespread use mobile communication, the question of how to strengthen the signal of the phone, or rather cellular communication, to which it is connected. It does not matter if you live in a small village or in a metropolis, the probability of your device stopping to catch a signal is everywhere. Gradually, this problem is solved by operators, new base stations are emerging, communications are increasing. And what if the problem lies in your phone, and not on the network? Today we decided to figure out what the bad level of the signal is connected with and whether it can be fixed by our own hands.

The principle of operation of cellular communication is quite simple: there is a base station of the operator and your phone, between them is organized a radio frequency channel, through which SMS-messages are transmitted, calls are made to exchange data on the Internet. There are several standards of cellular communication, differing in the way the signal is transmitted and the frequency. As a rule, base stations are built on high ground in order to provide the maximum coverage area. However, you can not escape the obstacles that prevent the signal from passing. It can be both walls, and trees, and other obstacles, when contact with which the signal weakens.


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

Because of what do we have a weak phone signal?

Because of the above specified obstacles, so-called dead zones or holes in the coating can form. That is, the places where the signal is weak, unstable or completely absent. Where most often encounter a bad signal on the phone:

  • places that are located at a significant distance from the nearest station (there is simply no coverage);
  • cellars, underground parking, lowlands (the signal can not simply penetrate here);
  • elevations, skyscrapers (often "to rise higher" does not mean the presence of a signal - above 12-14 floors, there is often no signal at all);
  • buildings of metal structures that do not pass the signal.

However, not always the reason for the absence of a signal is obstruction and remoteness from the station. Often the cause is the user's phone. You've probably been in situations where a friend has a cellular signal, and you do not. And it is with this that you use the services of one operator. There are cases when on two identical telephones a different signal level is observed. There can be many reasons:

  • the phone in a metal case or in a metal case can be much worse for catching a network than a plastic device;
  • quite often, no matter how surprising it is for you, the reason is the "clumsy" firmware of the phone;
  • damage to any components as a result of falls, diving, and so on;
  • the phone can be with a defect in the antenna from the factory, which is particularly bad for Chinese manufacturers of low-cost models.

How to strengthen the phone's signal with your own hands?

Well, went through the theory, go to practice. We will analyze several ways to enhance the cellular signal, from the simplest ones to the rather complicated and expensive ones.

Reason for firmware


To begin it is with the verification of the correct operation of the software, before trying to get to the insides of the phone. With the deterioration of the communication signal, which appear after the flashing, hundreds of users are faced, so attention should be focused. we already wrote, so we will not repeat. Firmware - the process is fairly simple, but with its own nuances. The main thing - do not forget to do backups  important files.

If, the firmware has helped, then we congratulate you, if the phone still does not catch the network, then proceed to the next point.


The signal is poorly caught due to phone damage

As already noted, the phone often catches a bad signal 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 the service center. Modern phones are quite complex devices, because most people can not identify the source of the problem independently. It is likely that the specialists will find the damage and will do the necessary work, so that your phone again without any problems copes with the search for the network.

How to strengthen the phone signal yourself


In most cases, the cause of a weak cellular signal lies in the antenna defect, 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 has a little shlturil, loosely connecting the antenna with motherboard  device. You can correct the mistake yourself, but you need to understand at least a little how the phone is arranged. Otherwise - contact the service center with a description of the problem.

  1. now smartphones are represented by a variety of designs, so they understand differently; the most easy to get to the insides of the phone with a removable lid and battery is more difficult when the smartphone is not folding;

Do not hurry. Before starting the disassembly, find on the Internet a video or text material in which you will be shown and told how the disassembly of your device is being done, what you should pay attention to.

Pay attention also: after disassembling the smartphone, you lose the warranty.

  1. as a rule, the antenna is hiding in the lower or upper part of the case, it is represented by small copper strips (again, refer to the corresponding materials about the location of the antenna in your model);
  2. after you reach the board, you will find several spring contacts, which should fit snugly to the loop located on the rear of the structure;
  3. if the spring contacts motherboard  badly adhere to the train, gently correct them, armed, for example, with tweezers;
  4. we collect the phone and enjoy a good network signal.
Connect a homemade antenna to the phone to amplify the signal


The above methods work only if the problem lies in your phone. But, as we noted at the beginning of the material, the reason bad signal  there may be various kinds of obstructions or substantial removal 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, a special diagnostic port will be required, which is difficult to obtain in a modern, non-separable smartphone (in a number of models it can not be found at all). It looks like a small connector of round shape of golden color.

    take a small piece of thin insulated wire;

    insert it into the connector;

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

All, as practice shows, the signal of the telephone network is amplified to a large extent. Is not it amazing ?!


Some users put a piece of wire in the port 3.5 mm (under the headphones). Sometimes it works.

Sticker-sticker or foil to amplify the phone signal


On the expanses 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 used, which is a few metal tracks, which, according to the manufacturer, can get rid of interference.

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

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

Reinforcing communication with a repeater

In some cases, when the signal can not be amplified by any of the methods (too thick walls of the room, distance from base station) resort to the use of special antennas or repeaters. Such devices can greatly enhance the signal, but their cost often discourages 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 people use the following method:

  1. take a metal rod (50 cm is enough), a coaxial cable, a piece of foil (about 10x4 cm) and plywood or plastic;
  2. bend the metal rod so that we get a design in the form of a diamond;
  3. we glue the foil to the plywood;
  4. metal rhombus and foil are connected by means of a coaxial cable (soldered);
  5. the end on which the diamond was found, raise higher, the other, with foil, - leave it below;
  6. we bring the phone to the foil to check the signal quality.

Probably, you will need to find the resulting design the most suitable place to catch the signal.

It's clear that such an amplifier is unlikely to provide a connection to a large company, which was not lucky enough to have an office in an area without network coverage. There will already have to seek help from specialists. Today, many companies provide similar services, not only offering modern equipment, but also installing. By the way, experts do not need to save money - for installation, employees use special devices that help determine the most suitable place, to select frequencies and so on. Usual user, of course, it will be difficult to cope with such a task.


The positive thing is that engineers have already thought up several options for getting rid of such inconveniences. The disadvantages include the requirements for additional financial investments and the complexity of setting up communication enhancement systems. However, we will not run ahead and tell about all this in order.

Signal amplifier for mobile phone

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

The amplification of the signal is due to a change in the directivity pattern of the own antenna of the telephone 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 the mobile phone on a narrowly focused one. Simply put, the signal will improve significantly when you point the phone toward the tower mobile operator. In other cases, the quality of the signal will fall. How effective is this mobile signal amplifier for you personally, is, of course, determined by yourself.

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

Amplifier cellular signal  The ThinkGeek mobile phone consists of a small antenna and a direct amplifier, which is inserted into the USB connector of your laptop. The length of the cord allows you to cover a radius of 4.5 m from the user, and the zone good signal  while it spreads to 1.5 m from the computer.

Undoubted advantage of such devices is their budget, but the obvious limitations of the action makes them ineffective for large companies.

Amplifier mobile signal  for large areas

Effective systems that can solve the problem of a bad signal in enterprises, in basements or, for example, in country houses, consist of a number of devices selected and configured properly. Signal amplifier mobile internet  has a similar structure and consists of similar components.

As the receiving element of such systems is the antenna, which is most often installed on the mast and directed towards the tower of the mobile operator. The problem is the need to lay cables of great length to the internal antennas, which weakens the signal strength in proportion to the footage.

To reduce signal loss, at the maximum possible distance to the receiving antenna, a repeater is mounted, which amplifies the GSM signal. Repeaters are characterized by gain factors (CG), output power and differ in operating ranges. For transmission amplified signal  in specific rooms, rooms, etc. use a divider that splits the signal into internal antennas.

Internal antennas also have their own CG and are designed for a certain coverage area.

It is worth knowing that incorrectly selected or assembled equipment has the opposite effect and dampens the already weak signal. Mobile operators can give a warning to the owner of such a system, and in the absence of a reaction, to obtain penalties through the Radiation Control. The conclusion suggests itself: if you are not sure of your own strength, it is better to turn to specialists.

Right now, every second citizen of the Russian Federation needs access to the Internet. However, there are cases when in any village, village or just on the outskirts of the city there is no possibility to connect to the 3G signal of the mobile operator. The phenomenon is common, since the signal is very distorted by natural obstacles: trees, buildings, etc. If you want to improve the reception of 3G, you will need a signal amplifier or an antenna 3g.

So, 3G signal can be strengthened:

  • without the use of special equipment;
  • with the help of antennas.

Gain without the use of special equipment

In order to increase the signal strength in a room or in a cottage, it is necessary to make sure that the signal reaches the antenna of the phone or usb modem as much as possible. If the usb modem is connected to a Wi-Fi router, then using an extension cable, it's best to take it as far as possible to the street and lock it somewhere higher, for example, under the visor. Typically, this method is effective. If this did not help, you can make an analogue of a satellite dish from a bowl or a saucepan. The signal screens from the surface of the "plate", and the power rises.

Antenna amplification

If you especially do not want to waste time building such installations, then you can buy a conventional antenna-amplifier. The blessing in various shops and on Internet sites on sale of the Chinese goods of such antennas is a lot. The antenna itself is an installation in which the transmitter is hidden, which increases the level of the mobile signal several times, in comparison with the telephone antenna or the antenna of the usb modem. The cost of such a device will be about 1500 rubles.

A modern 3G phone is mobile phone, compatible with 3G technologies of the third generation, which significantly increase the speed of information exchange. However, like most others mobile networks, the 3G network periodically has problems with weak signal reception. Moreover, since 3G constantly establishes an Internet connection, a low level of cellular communication closes access to you and the Internet for you.

How to improve 3G signal

To improve the quality of 3G signal is not difficult, if you know how to do it. On our website we offer you easy-to-use and inexpensive devices designed to amplify the signal. The 3G data transfer rate is directly proportional to the signal strength, so by amplifying the signal, you also increase the data transfer rate. The 3G signal amplifier is a simple solution to many problems with your 3G network.

3G Signal Repeater

3G amplifiers comes complete with two antennas - external and internal. While the internal antenna is connected to your phone, the external antenna is connected to the nearest mobile operator's tower. These antennas enhance and improve the reception of 3G signal.

Coverage Area internal antenna  depends on the quality of the incoming signal, so ideally the device should be installed outside the building or near the window for better signal reception.

Advantages of the 3G signal amplifier

To ensure high-quality reception, the 3G signal amplifier can be used everywhere, even in the car. 3G technology implies a high data transfer rate, which is achieved with this device. This improves not only the strength of the signal, but also increases the life of your mobile phone.

The 3G signal amplifier is easy to install and easy to use, giving you unhindered access to the 3G network wherever you are. This device increases the coverage area of ​​the network, allowing you to use the phone without any interference, both for sound calls and for other tasks. By amplifying the 3G signal, you also reduce the amount of radiation that the phone emits, thereby increasing its service life, and benefit your health.

The coverage area of ​​the 3G signal amplifier can be different, depending on your needs. We have a wide selection of 3G signal amplifiers on our site.




How to improve 3G signal

Like any other cellular repeater or amplifiers, 3G amplifiers not only help improve the quality of signal reception during telephone conversations, but also increase the data transfer speed, which is very important when using the Internet.

Thanks to the 3G amplifier, you will always be in touch with the outside world and will be able to solve all personal and professional issues quickly and without problems.
