Bad cellular signal how to strengthen. How to improve cellular quality in the apartment. Installing an antenna and repeater

Coating networks at cellular operators is not solid. And no one will do it with solid - it is economically unprofitable. A certain contribution to the propagation of radio waves is made here, which is why the radioline zones may occur in certain points. Bad reception signal cellular communication - This problem is relevant for many people, especially for those who live outside the city, away from the nearest basic stations. Let's try to solve this problem together.

On the Internet thousands of complaints on cellular operators - people complain that they are experiencing problems with communication. Unfortunately, no one will do so that the signal is taken everywhere and with the same force. It is impossible due to economic reasons, it is impossible due to certain physical reasons. Russian operators in general work well, and they have a decent coverage area - this is confirmed by the evaluative comparisons with European operators. Just you just a little lucky with a location.

If you complain about the bad level of the MTS signal in your area, nothing prevents the neighbors and find out what operator they use. It is possible that the Beeline or Megaphone will work with you much better, pleased with the stable admission. Even tele2, not always distinguished by a wide coverage area, in recent years has significantly increased coverage of its networks - you can try.

Transfer of the number to another operator

You can argue - they say, I do not want to change the operator, even if the signal of another operator is caught at times better. This is called "the neighbor's neighbor called the ears." Do not change if you do not want - sit in the wilderness and rejoice in the absence of communication. For others, we can offer a reasonable solution - if MTS is not caught in your area, and Beeline is caught, go to the biline office and write an application for transferring the number.

The advantages of this approach:

After 8-9 days you will earn mobile phone - It will be served in the network of another operator, and you will forget what is a bad network coverage.
You can choose a more profitable tariff plan.
You will stay with your number - it is not necessary to change it at all.

This is the optimal way to combat the poor reception of a cellular signal, but it will require preliminary research - it is necessary to determine which operator works best in your area.

Buying another phone

It cannot be said that this is the most optimal way to solve a problem with a bad signal reception. All modern tubes have approximately the same sensitivity. Therefore, the purchase of another smartphone may pour into extra costs. And conversations of the admirers of Apple that iPhones "catch anywhere", no more than a myth.

Find a phone with high sensitivity for bad conditions of reception problematic. A few years ago they were, but then somewhere disappeared. People living in remote areas advise to look for old Nokia and Motorola mobile phones - they differed in high sensitivity.

DEXP LARUS X2 Rev.2.
BQ Rome BQD-2051.
Termit Fixphone V2.

Their cost does not exceed 3000 rubles, and the antenna protruding from the buildings will provide increased sensitivity.

It is more difficult to solve the problem with the reception of 3G and 4G signals, since only modern phones work with them.

Using external antennas

Improve voice quality and increase mobile Internet speeds will help external antennas. They are connected to phones equipped with appropriate sockets. Unfortunately, they are equipped with extremely limited quantity Models. Let's see, to which tubes we can connect external antennas, allowing to improve the reception of the cellular network signal:

Huawei ETS5623 is a stationary cell phone complete with a remote antenna and cable motor 10 meters. Cost - about 4 thousand rubles. Excellent solution with poor reception of the signal of cellular networks.
Runbo H1 is a very expensive smartphone worth almost 60 thousand rubles, performed in a shockproof and waterproof case. It is equipped with a connector under external antenna.
Kit MT3020B is another landline apparatus equipped with a socket under an external antenna that comes in the kit. The cost of the phone is about 5.5 thousand rubles.

We also recommend paying attention to the tubes of the past decade - they are often equipped with connectors for antenna (including hidden under the back cover) to work in conditions of poor reception of the cellular signal.

Cellular communication is needed not only for voice transmission, but also to access the mobile Internet. And if we cannot find a smartphone with a connector under an outer antenna, then 3G- and 4G modems are fully with them. Literally to each second modem you can connect an antenna that will significantly improve the quality of the reception.

Passive repeaters

The use of passive repeaters allows you to improve the reception of a cellular signal without expensive electronics. Most often these are self-made devices, which are a bunch of two small antennas. Also in designs are used beer cans, copper wire, some other unthinkable household goods. All this is not serious, and also limits the freedom of movement around the house - you have to talk on the phone with a direct location next to such a repeater.

There is one more interesting technical solution. If the smartphone does not have a nest under the antenna, you can do as follows:

Buy one directed GSM antenna and one pin GSM antenna.
Set the directional antenna on the roof of the house, on a tree or post up to 10 meters high (the more, the better).
Install a pin antenna in the house.
Connect both antennas cable.

Now the Internet is needed literally every second citizen of the Russian Federation. However, there are cases when there is no possibility of connecting to a 3G signal of the mobile operator in any village, village or simply on the outskirts of the city. The phenomenon is ordinary, since the signal is very distorted by natural obstacles: trees, buildings, etc. If you want to improve the reception 3G, you will need a signal amplifier or antenna 3G.

So, the 3G signal can be strengthened:

without the use of special equipment;
with antennas.

Strengthening without the use of special equipment

In order to increase the power of the signal in the room or in the country, it is necessary to make the signal to the maximum reaching the phone or USB modem antenna. If the USB modem is connected to a Wi-Fi-router, then with the help of the extension, it is better to withdraw it as far away to the street and secure somewhere higher, for example, under the visor. As a rule, this method is effective. If it does not help, you can make an analogue of a satellite plates from a bowl or pan. The signal shields from the surface of the "plates", and the power rises.

Binding with antenna

If you do not particularly want to spend time on the construction of such installations, you can buy a conventional amplifier antenna. Fortunately in various stores and online websites chinese goods There are a lot of such antennas. The antenna itself is a setting in which the transmitter is hidden, which increases at times, compared with the telephone antenna or antenna USB modem, the level of the mobile signal. Conduct such a device will be about 1,500 rubles.

It seems that at present cellular communication is everywhere. Already exactly in major cities, she is everywhere! And in the stunning villages, of course, she is weak or not at all. This commodity opinion is often deceptive. Since even in large megalopolis, there are a lot of "blind spots" where the improvement of cellular communication is required.

Why does the need arise in improving mobile phone reception?

At the heart of all problems with mobile communications - screening of a cellular signal objects or a large remote control of the base station. Signing the signal may be adjacent buildings, walls of the building, overlap slabs and more. Therefore, the improvement of cellular signals becomes necessary.

Movement Movement Methods

In order to improve the connection on the phone, you can try to keep it in a conversation in a different way - with two fingers instead of the palm, behind the top, behind the middle or bottom of the phone or shifting into another hand. The fact is that the person's hand can close the antenna built into the telephone and significantly worsen the quality of her work, which becomes critical in zones with a weak welcome.

As a rule, cellular communication is improving if climbing on elevation - hillock, hill or attic at home. To improve communication on the phone, you can change the cellular operator, as the base stations different operators Located in different places and work with different power.

How to improve mobile communications with repeater

However, often all of the above methods do not allow the result or simply inconvenient. If you want to improve the quality of cellular communication at home, in the office or in the country, then the most convenient and effective method - Install the cell signal strengthening system. Such a system consists of an external antenna that is installed outside the room (on the wall or on the roof), the repeater and internal antenna, which are indoors. This system creates a "zone of confident reception", within which you can easily talk on a mobile phone. - Set of Vegatel VT-900-Kit or SOTOBOX self install kit

Posstanding the search for the device to enhance the cellular signal, the buyer faces an abundance of brands, models, manufacturers, which usually puts it in a dead end. What to choose to improve mobile communications? Engineers of our company daily solve clients to improve cellular quality. After long-term operation of the signal to enhance the signal mobile communications Different manufacturers, our company has made a choice in favor of the Russian manufacturer Vegatel. For myself, we decided that this is the best of what is represented in the domestic market.

Vegatel equipment distinguish:
Optimal price-quality ratio. Vegatel equipment does not apply to the equipment of the lowest price segment. However, the quality and stability of its work is significantly higher than Chinese analogues. This equipment always issues the characteristics declared by the manufacturer and does not create interference with base stations of cellular operators.
A wide range of reinforcing equipment in which there is a large number of dual-band repeater, which allows you to strengthen all cellular operators working in this area for low cost.
Technical support All customers. In the event of difficulties in installing and during operation, you can always get full consultation from Vegatel specialists.
The full range of all necessary for the implementation of projects to enhance cellular communication. Vegatel produces not only repeaters but also boosters, antennas, antenna amplifiers, attenuators, splitters and splitters.

Despite the widespread mobile connection, the question is still relevant how to strengthen the phone signal, or rather cellular communication to which it is connected. It does not matter whether you live in a small village, or in a metropolis, the likelihood that your device will stop catching the signal, everywhere. Gradually, this problem is solved by operators, new base stations appear, the connection increases. And what if the problem lies in your phone, and not on the network? Today we decided to figure out, what is the bad signal level associated with and whether it is possible to fix it with your own hands.

The principle of cellular communication is simple enough: there is the base station of the operator and your phone, the radio frequency channel is organized between them, according to which SMS is transmitted, the calls are made. There are several cellular standards that are characterized by signal transmission and frequency. As a rule, basic stations are erected on the hills, in order to provide the maximum coverage area. However, you can not get anywhere from obstacles that prevent the passage of the signal. It can be walls, trees, and other obstacles, when contacting with which the signal is weakened.

It is clear that in the open area, where high-rise buildings are not replete, 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. Under the conditions of urban development, the figure decreases to 7 kilometers. Stations with more advanced communication standards in the face 3G and LTE cover the zone twice the smaller diameter.

Because of what we have a weak phone signal?

Because of the above stipulated barriers, so-called dead zones or holes in the coating can be formed. That is, places where the signal is weak, unstable or no. Where most often faced with a bad signal level on the phone:

places that are substantially removed from the nearest station (simply no coating);
basements, underground parking, lowlands (the signal is not fair to penetrate here);
hills, skyscrapers (often "climb higher" does not mean the mandatory signal presence - above 12-14 floors there is often no signal at all);
buildings from metal structures that do not pass the signal.

However, it is not always the reason for the absence of a signal become barriers and remoteness from the station. Often the user becomes the phone. You probably have been in situations when familiar has a cellular signal, and you have no. And this is how you use the services of one operator. Cases are common when different levels of the signal are observed on two identical phones. The reasons can be a lot:

the phone in the metal case or in a metal case can be much worse to catch the network than plastic device;
quite often, how surprisingly it did not sound for you, the reason for the phone firmware becomes the cause;
damage to any components as a result of drops, dives in water and so on;
the phone can be with an antenna defect from the factory than the Chinese manufacturers of inexpensive models are particularly sinned.

How to strengthen the phone signal with your own hands?

Well, passed on the theory, go to practice. We will analyze several ways to enhance cellular signal, starting with the most simple, finishing quite complicated and expensive.

Cause in the firmware

Start worth it with checking the correctness of work softwareBefore trying to get to the insides of the phone. With a worsening of the communication signal appearing after flashing, hundreds of users face, so attention should be sharpened. We have already written, so we will not repeat. Firmware - the process is quite simple, but with your nuances. The main thing is not to forget to back up important files.

If, the flashing helped, then we congratulate you if the phone is still poorly catching the network, then go to the next item.

The signal is badly caught due to phone damage

As noted, often the phone badly catches the signal after accidentally fell on the tile or plunged into the sea. In this case, the average user does not have another output except to go to service center. Modern phones are pretty sophisticated devicesTherefore, most identify the source of the problem is not possible. It is likely that experts will detect damage and will produce the necessary work so that your phone will reiterate without any special problems with the search for the network.

How to strengthen the phone signal with your own hands

In most cases, the cause of a weak cellular signal lies in an antenna defect, which, in fact, is responsible for this function. Often the owners of inexpensive smartphones from the Middle Kingdom face that the manufacturer has a little scattering, connecting the antenna with the motherboard device. It is possible to fix the emboss on yourself, but you need to at least understand a little as the phone is arranged. Otherwise, we appeal to the service center with a description of the problem.

today, smartphones are represented by the most different design, therefore they understand differently; Most simple to get to the interns with the phone with a removable lid and the battery, more complicated when the smartphone is non-separable;

Do not hurry. Before starting the disassembly, find the video or text material on the Internet, which will be shown and described how the disassembly specifically disassemble your device to pay attention to.

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

as a rule, the antenna is hidden in the lower or upper part of the case, represented by small copper strips (again, about the arrangement of the antenna specifically in your model, see the appropriate materials);
after getting to the board, you will find several spring contacts that must fit tightly to the loop located on the back of the design;
if the spring contacts of the motherboard are poorly adjacent to the loop, carefully correct them, armed, for example, tweezers;
we collect the phone and enjoy a good network signal.

Connect to the phone homemade antenna to enhance the signal

The methods discussed above work only 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 of various kinds of obstacles or a significant removal from the station. In this case, you can try to strengthen the antenna of our device using the entire piece of the wire.

Immediately note that the method is not suitable for all phones. The fact is that for its implementation, a special diagnostic port will be required, to which it is difficult to get in a modern unintebral smartphone (in a number of models it is not at all). It looks like a small round-shaped connector of golden color.

we take a small piece of fine insulated wire;

insert into the connector;

we put so that you do not interfere with other components and closing the lid.

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

Some users piece of wire inserted into port 3.5 mm (under headphones). Sometimes it works.

Sticker-sticker or foil to enhance the phone signal

On the expanses of foreign online stores will not be difficult to find a bunch of different devices for amplifying the signal. Among them is popular with a small sticker sticker, which is several metal tracks, which, according to the manufacturer, allow you to get rid of interference.

Such 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 minor signal improvement, as a considerable number of users approves, a piece of ordinary foil will help. It is placed under the lid of the phone, closer to the antenna. The way is simple, so you can try.

Strengthening communication with repeater

In some cases, when the signal fails to strengthen any methods (too thick walls of the room, remoteness from the base station) resort to the use of special antennas or repeaters. Such devices are capable of significantly increase the signal, but also the cost of them often scares the potential buyer.

Where to buy cheap?

Something similar can be built and with your own hands, but often it does not increase the signal at all or does it very much and very bad.

For example, some are used in the following way:

we take a metal rod (50 cm enough), a coaxial cable, a piece of foil (approximately 10x4 cm) and a phaneer or plastic;
flexing the metal rod so that we have a design in the form of a rhombus;
foil glue to plywood;
metal rhombus and foil connect through a coaxial cable (solder);
the end on which the rhombus turned out to raise higher, the other, with the foil, - we leave downstairs;
drive the phone to foil to check the quality of the signal.

It is likely that you will need to find the resulting design of the most suitable place to catch the signal.

It is clear that such an amplifier is unlikely to ensure a large company with a link, which was not lucky to have an office in the area without covering the network. Here you will have to seek help from specialists. Today, quite a few firms provide such services, and not only will offer modern equipment, but also will be installed. By the way, it is not worth saving in experts - for mounting, employees use special devices that help determine the most suitable place, pick up frequencies and so on. The usual user, of course, will be difficult to cope with such a task.

A positive point is that several options for getting rid of such inconvenience are already invented by engineers. The minuses include requirements for additional financial investments and the complexity of setting up communication systems. However, we will not run forward and tell about all this in order.

Signal amplifier for mobile phone

The simplest option to avoid a weak signal is to install an amplifier not on a specific area or building, but on a specific phone. Similar antenna amplifiers look like stickers and pasted inside the machine housing or on its back cover.

The signal amplification occurs due to the change in the electron diagram of the phone's own antenna and increasing the overall induction of two antennas.

The disadvantage of this method can be considered a change in the circular reception of the mobile phone on the narrow-directional one. Simply put, the signal is significantly improved in the case when you send the phone towards the tower mobile operator. In other cases, the quality of the signal will fall on the contrary. How effective is the similar amplifier of the mobile signal signal for you personally, it is worth it, of course, to decide on your own.

The following way to strengthen the quality of communication is the point amplifier of the mobile signal signal with a small coating radius. This option is suitable for cases when the zone of the confident signal is only a few meters from your workplace.

Thinkgeek mobile phone cells amplifier consists of a small antenna and directly amplifier, which is inserted into the USB connector of your laptop. The length of the cord allows to cover the radius of 4.5 m from the user, and the zone of a good signal will spread by 1.5 m from the computer.

The undoubted advantage of such devices is their budget, however, the explicit limit of the action makes them ineffective for large companies.

Mobile signal amplifier for large areas

Effective systems capable of solving the problem of a bad signal at enterprises, in basement or, for example, in country housesConsist from a number of devices selected and tuned properly. Mobile Internet signal amplifier has a similar structure and consists of similar components.

As a receiving element of such systems, antenna is the antenna, which is most often installed on the mast and direct in the direction of the tower of the mobile operator. The problem is the need to lay the cables of a large length to the internal antennas, which weakens the signal strength in proportion to the intergument.

To reduce the loss of the signal, the repeater that enhances the GSM signal, which increases the GSM signal as possible to the receiving antenna. Repeators are characterized by amplification coefficients (KU), output power and differ in working ranges. To transfer the reinforced signal into specific rooms, rooms, etc. Use a divider that brends a signal to internal antennas.

Internal antennas also have their own ki and are designed for a specific coating area.

It is worth knowing that incorrectly chosen or assembled equipment has the opposite effect and jammed weak signal. Mobile operators can prevent the owner of a similar system, and in the absence of a reaction to achieve penalties through the radioadzor. The conclusion suggests itself: if you are not sure of your own forces, it is better to contact the specialists.

Modern 3G phone is a mobile phone compatible with 3G third-generation technologies that significantly increase the rate of information sharing. However, like most other mobile networks, the 3G network periodically has problems with weak signal reception. Moreover, since 3G constantly establishes an internet connection, a low cellular level closes access to and Internet access to you.

How to improve 3G signal

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

Repeater 3G signals

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

The internal antenna coating zone depends on the quality of the incoming signal, so ideally the device must be installed outside the building or near the window for better reception of the signal.

Advantages of the 3G signal amplifier

To provide high-quality reception, the 3G signal amplifier can be used everywhere, even in a car. The 3G technology assumes a high data transfer rate, which is achieved using this instrument. At the same time, not only the power of the signal is improved, but also the service life of your mobile phone.

The 3G signal amplifier is easily installed and easy to use, providing you with unhindered access to the 3G network, wherever you are. This device increases the network coverage area, allowing you to use the phone without interference for both audio calls and other tasks. Enhanced 3G signal, you also reduce the amount of radiation that the phone eves, thereby increasing the duration of its service, and benefit your health.

The 3G signal coating zone can be different, depending on your needs. On our site is provided wide selection 3G signal amplifiers.

How to improve 3G signal

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

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

The deterioration of the cellular network is a common problem even in large megalopolis. Fortunately, strengthen the signal in the apartment is not difficult - it is enough to know the subtleties and solutions to the problem.

Why do the apartment arise with cellular communication?

Subscribers of any operators can complain about failures and interference during conversations on mobile, problems with sending and adopting SMS, as well as poor quality of the Internet connection. Problems of this kind are related to the connection, and their causes are varied:

The apartment is far from the antennas of base stations. Most often, such a reason is possible in small cities and villages in removal from urban areas. The farther from the source of the communication, the worse the quality of the connection. A similar problem occurs if the tower antenna is deployed in the opposite direction from the room.
Barriers and interference. On the path of the signal, high trees and buildings may come across, as well as large pillars and other buildings. A large amount of concrete and metal structures can interfere with the signal to reach your apartment, provoking problems with the network.
Signal weakening. The reason lies in the thick walls of houses and dense multi-layered double-glazed windows.

Important. The problem of the relaxation of the signal is particularly relevant for the lower floors and the basement - the signal can be lost completely.

Interference, or overlay network signals from different base stations to each other. Such an effect is possible if the operator put into operation a new station.

Important. When interference, the phone can quickly discharge, and conversations may unexpectedly interrupt. The reason is that the phone is trying to simultaneously take two similar signals.

Using outdated equipment. It often happens that operators use low-quality or outdated towers whose work may not be permanent.

What is required to solve the problem?

You can solve problems with the loss of quality of the cellular network, you can install additional equipment - router, repeater and special antennas to enhance the cellular signal in the apartment https://gsmusilenie.ru/kvartira.html.

The first option assumes the installation of 3G or 4G device that will receive an external signal using an antenna and distribute it in the form of Wi-Fi inside the apartment. The second option assumes the installation of repeaters and antennas, which are capable of improving GSM, 3G, 4G.

Thanks to the compactness of the devices and their modern installation, you can not worry about the safety of the walls and the interior.

How does cellular strengthening system work?

The repeater signal strengthening system works with GSM, 3G and 4G. This option is especially relevant for those who have in the apartment interruptions with voice communications and the Internet.

The process of installing the equipment involves the installation of a donor (receiving) antenna located on the street, as well as the signal amplifier (repeater) and service antennas located in the apartment. External and internal devices are connected by cable. Street antenna takes a signal that passes through the amplifier and is transmitted to the antenna located in the apartment.

Internal antennas can distribute the network not only on smartphones and tablets, but also on routers, modems and other devices.

The cost of solving a cellular strengthening in the apartment is from which the kit consists and how the cost is

Options for the choice and installation of equipment are not recommended independently - otherwise you can disrupt the operation of the networks and get harm rather than the benefit. The cost of services of companies engaged in the strengthening of the cellular network in apartments and country houses is made up of several factors:

Apartments and number of rooms;
Signal level in the apartment and on the street (number of divisions);
Hard-to-access and complexity of installation and device settings;
Wishes of the customer.

Among the main components of the cost of equipment and its installation are the area of \u200b\u200bthe room and the level of the network. The number and power of the necessary receiver and internal antennas, and the type, location and power of donor antennas depend on the first. The larger area of \u200b\u200bthe room, the thicker of its wall and the lower it is located, the greater the number and the necessary power of the devices. The weaker radio signal in the room, the more powerful there should be an external donor antenna.

Important. A package of equipment with installation, selection, consultations of specialists and their departure to the house varies from several thousand to several tens of thousands. Batch suggestions, as a rule, begins from 9-10 thousand rubles.

Internet - an indispensable thing in modern world. The more we need a mobile Internet, the annoying to detect a bad signal or even it complete absence. Although the quality of cellular communications has improved in recent years, it is still often brought. How to fix the low quality 3G signal and what to do for this?

Causes of a bad mobile signal signal: can it be improved

Cellular communication problems and mobile Internet may be caused completely different sources: From remote from cellular steels to bad weather conditions. Let's wonder the most common reasons:

the remoteness of cellular tips;
third-party networks that violate the signal;
a large number of obstacles - high-rise buildings, metal structures, hills, mountains;
bad weather conditions - rain, thunderstorms, storms, etc.;
large network load - distributed in the evening;
hardware problems - for example, low phone charging.

You can improve the cellular signal, and here are the most obvious and simple ways:

be closer to cellular tower;
exit an open place or to the window - so that the barriers do not interfere with the "journey" of radio waves from the phone to the tower;
recharge the device - removal from cellular tower requires greater transmitter power, which is rapidly discharged by the battery.

Suddenly, I found that covers and accessories made of metal - either having metal inserts - can adversely affect the signal, quite like large metal structures. Owners of such accessories offer to try the speed of the Internet with a cover without it. The result may pleasantly surprise you.

Other ways are more complicated and not so obvious, they are associated with additional devices or programs. We will analyze them in more detail.

Strengthening communication using applications: pros and cons

On the Internet there is a large number of applications to enhance the signal. At the same time, you do not risk damaging the phone and do not spend money. Let's see if it really is?

Software improvement signal I will figure out the example of one of the popular and easy-to-use applications - Internet Speed \u200b\u200bMaster.

To use Internet Speed \u200b\u200bMaster, you only need to run the program and click the Apply Patch button for smartphones with root-rights or "Improve Internet Speed" for unwrapped phones. Whenever a bad signal, it is enough to use the application and the smartphone to use a strong and stable network signal.

Root-Right or Suspector Rights is full access to all data data. It is thanks to root-rights, the user can get "limitless" access to all files on the Android device.

Wikipedia.
https://ru.wikipedia.org/wiki/root.

The Internet Speed \u200b\u200bMaster program has an extremely simple and understandable interface.

Be careful if you want to get root rights.Careless use of the rights of the "superuser" can easily turn the smartphone in "Brick". It is better to reinforce it once again than to regret the loss of the device.

Consider all the pros and cons of this application and the method as a whole.

Promotional Pluses:

simple and understandable interface for most applications;
the method does not require material costs;
applications do not require your intervention - just press a pair of buttons;
the way can be checked in a couple of minutes, without even leaving home.

Cons of the software:

not on all devices gives a positive result;
many applications require root rights.

Disadvantages compared to the benefits are insignificant. It is safe to say that trying to try this method at a bad signal will not hurt.

Use of purchased or homemade antennas to enhance communication

The level of the cellular signal is measured in decibels (dB) and varies from -50 dB (excellent signal) to -120 dB (no signal). Antennas, repeaters, repeaters and other equipment enhances this level by improving communication.

The quality of the cellular network varies from -50 dB to -120 dB

You can find out the level of the Android signal in the following way:

If the previous method has had an insufficient improvement in the quality of the signal, then you should try to increase the speed of communication with the antenna. The cost of purchased antenna begins from 1300 rubles. The range of equipment is quite wide and among Chinese devices, and in Russian manufacturers.

The pin antenna is an inexpensive and easy way to strengthen communication signal

The main difference between the antennas is the directional diagram - the most common antennas with circular (can catch a signal from all sides) and aimed (maximum effect when directed towards cellular tower) diagrams. Also, the antennas differ in shape. The most popular - pin and panel.

Another variety of antennas - panel

If for some reason you do not want to acquire an antenna, you can also build it with your own hands using simple technicians. It does not require special Knowledge, so for most users.

Using repeaters (repeater)

Repeaters or repeaters are more complex and expensive devices than antenna. Prices for repeater start from 7,000 rubles, however, and increase the quality of the signal they are stronger. Even the most inexpensive devices coverage area reaches 200m² at good conditions (signal in 3-4 sticks). And expensive models (from 40,000) may well cover several floors of an office building or shopping center.

Repeators - Some of the best devices for amplifying the signal

Installation of cellular relayers

If you have already selected a suitable device, you need to install it correctly. Of course, you can use the services of the masters, but it is quite real for the installation itself. To do this, it is enough to use the instructions:

Install an external antenna outdoor. At the same time, directional antennas must be viewed in the direction of cellular tower.
Internal antennas located indoors at least five meters below external.
Connect the external and internal antenna cables, connect to the relay.
Connect the power repeater and check the availability of power.

In case you are not sure where the cellular station is located, ask someone to be in the inner antenna, and slowly turn the antenna yourself until you find the highest quality signal.

If everything is done correctly, the signal level near the internal antenna will increase significantly, approaching the maximum.

Other 3G signal amplifiers

You can find compact amplifiers in the form of stickers, located inside the smartphone housing. They are a geometric pattern of several metal stripes. The manufacturer claims that the amplifier reduces the number of interference and improves the signal in places where it is almost absent. On Aliexpress website, these stickers are sold for 10 pieces for only 140 rubles, but their effectiveness, which is called, is relumed at anywhere and most of the comments are not observed.

Similar small stickers can improve communication

Instead of such stickers, many simple users and even experts argue that even a regular piece of foil helps to receive an increase to the signal, located under the lid of the phone. This method requires minimum costsTherefore, it is quite suitable for verification.

The main reasons for the bad signal lies in the remoteness of cellular stations and deaf terrain, but the quality of communication is somehow improving the simple and not very means. Non-good manipulations give a solid increase to the speed of communication. It remains only to wish quick Internet!

In the villages, until the present time of the allocated internet line, in most cases there is no. It happens, the Internet can be connected via ADSL line, who has a connected landline phone.

In most cases, all rustic residents of Russia are connected to the Internet using 3G modems. And the further the village, the worse, not only the Internet 3G, but also the usual cellular communication.

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

Using antenna.
Using antenna and amplifiers.
Using multiple antennas and multiple amplifiers.

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

You need to know exactly what the band is transmitted to the signal of the selected telecom operator, and where the boundaries of this signal are transmitted. An ordinary cell phone or spectrum analyzer is suitable for checking the signal level.

Check the signal level

Before you so much, you need to catch something. We define the range of voice and Internet operating frequencies. The image above illustrates the entire spectrum of the activated frequencies: the television signal, Wi-Fi, DECT, GSM, LTE, etc. It is important to understand the base station in what range the Internet is transmitted to the checkpoint. 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 standard data. In cities due to a small coating radius, but more high speed The signal transmission and stability of work with a large number of connections, use the UMTS 2100 standard.

If you are not an installation organization specializing in the 3G booster installation for one-time connection, you can use the phone with 3G support. Activate the built-in NetMonitor function.

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

When you enter the engineering menu, various information appears, for example, the volume level, battery charging, IMEI, Wi-Fi, phone use statistics. I do not recommend changing values.

You cannot find the options you need, use another phone. As a result, you need to determine the parameter RX CH. The first value circled with a red frame shows a signal from which range. If the value within 10562-10838 is UMTS 2100, if within 2937-3088 - UMTS 900. Having determined the range of work, you can unmistakably select the 3G signal amplifier, for example, high-quality Picocell 900 or Picocell 2000.

Yellow frame shows a 3G signal reception level. Having constantly changing dynamic signal level parameters, looking for a better reception point. Less is better. Ideally, the antenna is better to put higher on the roof, but you can find the points of confident reception inside the house.

Equipment selection

If you are in the reception zone, it is possible enough to install a good antenna with a large gain coefficient. For example, antenna AP-1900 / 2700-17 with a gain of 17 dB, but a narrow pattern of the orientation. This is suitable if one base station and other signal consumers are not installed next to you.

A fantastic result shows the antenna of the AO-2000-11 brand - with high ku \u003d 11 dB and a circular orientation chart. It works on the principle put and forgot. The advantage of it is in principle. It can catch a signal immediately from several 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 the 3G signal is at least to catch, it is enough to fasten the 3G-20000 PicoCell producer, and you will catch a stable 3G / 4G signal.

To prevent the loss of the signal between the antenna and the amplifier, I recommend using a cable with a large cross sectionwhose tips are compressed by an industrial method or a special tool.

Finished sets

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

Kits can be several types:

without amplifier;
with amplifier;

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

Antennas are selected based on terrain, quantity and distances to base stations. Always this kit can be increasing the amplifier, the total price of the equipment will grow as the quality of the received signal.

The antenna can be used any, including those given during the selection of equipment, but the modem is better to buy Huawei E392, though the price starts from 3200 rubles.

Look short video Total outlined in the article, if anyone is interested in the subtleties, go to the site specified in the video clip.

And finally, I will share observation: buy antenna and equipment in specialized stores, not in cell phone salons, what is selling there.

Connect antenna is made for the beauty of the interior. The usefulness of this device is doubtful. You can use only as an extension cord for modem
