I hate to fish, because I feel sorry for the wasted time. But, nevertheless, I've been preparing for fishing all week. The task was set to catch the mobile Internet and additional risks of the received signal level on the screen of a cell phone or smartphone, and it was necessary to catch it in the field without active amplifiers and batteries. This can be done with a passive repeater.
It probably already happened that in order to look at something on the Internet or call a cell phone, you almost had to climb onto the roof or hang halfway out of the window, catching the risk on the cell phone screen or stuffing S MS-ku to throw phone up, or raise along with the flag on the flagpole.
Try to make the simplest passive repeater of a 3G signal or a cell phone first. Two simple directional wire antennas, a coaxial cable connecting them, that's the whole design. Using such a simple mobile device that does not require power, you can provide communication in the basement, in a metal hangar or garage, in a de-energized bomb shelter, or anywhere else where a cellular signal does not reach.
The size of the antennas themselves will correspond to the selected communication frequency: for a cell phone, frequencies are 900 MHz and 1.8 GHz, for mobile Internet about 2 GHz. For the experiment, I made a 900 MHz antenna, but in practice it turned out to be also workable from 1.8 to 2 GHz. Subsequent measurements of a homemade antenna showed that the range of its excellent matching almost reached 2.080 GHz, otherwise I would not have received a 3G Internet signal.
If someone has already assembled from two wire rings, he can easily cope with the task. Everything is done in the same way.

| The diameter of the mandrel (glasses) is 4.3 cm. The frequency is 1.9 - 2.2 GHz. |
We determine the wavelength in meters L m = 300 / 900 MHz = 0.33 m
Wire coil (ring) diameter D = L / 3.14 = 0.33 / 3.14 = 0.106 (m)
Distance between rings S = L / 4 = 0.33 / 4 = 0.08 (m)
Accordingly, with increasing frequency - the frames will decrease in size, the losses in the coaxial cable will increase. Antennas at other frequencies will also be calculated.
How it works. One directional antenna, taken out of an absorbing reinforced concrete wall or raised above the metal roof of a country house, or simply raised above the ground, is oriented towards the base station. The second antenna, whether it is a basement, a country house, should be directed to a mobile phone or smartphone or be located next to them.
Since the antenna is directional, it has a gain, in a particular case, equal to 5 dB. Some of this gain will be lost in the cable. In the cable PK 75 - 3. 7-35, 6 meters long at a frequency of 900 MHz, I lost, as it turned out later, 3 dB, which, given the error, coincides with the technical characteristics of the feeder used. Antenna efficiency in free space with increasing height is better. It induced more field strength and improved line-of-sight with the base station, providing a stable connection, since houses and trees are no longer an obstacle to radio waves.
If you need to use several frequencies, you will need several repeaters with different ring diameters. Here, as in fishing, you need all kinds of bait, so I prepared gear like an avid angler, bending the wires like hooks of different diameters. Everything will depend on the conditions. Let's see what we can catch.

| Place of testing. |
It remains only to try. Here is the place of fishing, the old gazebo. A rod made of a miraculously preserved shortened antenna mast, which saved me when I was flying from the roof, and therefore I definitely won’t climb a tree, at my age the bones do not grow together well. The pole was extended with plastic tubes, in which low-voltage wires are usually laid. Even a wooden bead was used, because the antenna itself weighs little. Turning the fishing rod, I orient the rings towards the nearest town, temporarily turning into a fox hunter. Next to the antenna rings, which is below, I put my mobile phone.
With the help of a repeater, the mobile phone added three risks on the display, providing 100% communication with the nearest civilization (base station), located 6 kilometers beyond the forest. For those who like to chat for a long time on a cell phone outside the city, such a device is simply necessary. As a rule, far from the base stations, the phone gives out full power, which is unhealthy. The correct phone (meaning a small SAR value - sanitary standard), having a good connection with the base station, will give less power to the antenna, which means that the body will be less irradiated by the microwave field. But I already talked about this in the article.
By evening, there are more and more people who want to check their mobile phones and smartphones. Here the tablet came to life, slowly loading, showing individual pictures of television programs. The smartphone began to flip through the pages of the DED CLUB .... We moved a few meters away from the repeater, but the pages of the Internet continue to turn over.

| Everything is working. |
Or maybe it's a joke, maybe 3G is already working everywhere?
I, offended, fill up my fishing rod on the ground. From the dissatisfied faces, it is clear that everything is frozen, dashes and symbols have flown off the displays.
I hate fishing, so much free time is wasted!
True, I have not yet seen a fisherman who would not return to the old place to try another bait. Only the diameter of the mug (900 MHz) was tested, the diameter of the glasses is still ahead (2-2.2 GHz). Well, the bait on the spiral antenna will complete the catch , I foresee in advance that a heavy structure will turn out, but for a hospital that's what you need.
Yes, by the way about polarization. In a hurry, or maybe out of absent-mindedness, I completely forgot about it, and when I looked at the photographs, I remembered. Base mobile stations of cellular communication have antennas with vertical polarization, and therefore the tackle on the fishing rod had to be rotated 90 degrees, so that the section of the rings was not at the bottom, but on the side, which corresponded to a similar polarization. Nevertheless, the radio signal was able to catch even with the horizontal polarization of the rings on the mast, despite the minimum loss of 6 dB due to mismatches, the experiment was a success. And on the other hand, the forest has its own laws and the passage of a signal with horizontal polarization is better in it.
P.S.
Two years have passed. This summer, in 2016, I was preparing for the arrival of my grandchildren on vacation from their parents or vice versa, and decided to install digital television in the gazebo, watch cartoons, and even to catch my breath. So that the antenna would not be conspicuous, I wove it from wires and called it an invisible antenna. It turned out four rings, which, when receiving digital television, proved to be better than a two-ring design. I wrote in detail about this design in the article.
I wove similar two antennas for a passive mobile communication repeater for the 900 MHz band, just in case, suddenly someone needs the Internet. As of today, there is no Internet in our lowlands. The "H" icon appears, but it takes years to load. Having laid the double figure eight flat, he raised it to the level of the roof of the arbor, and it became invisible in the crown of a wild apple tree. Thanks to this design, the mobile phone added two to the two level risks. This seemed to be the end of the experiment, but there was still a moment of triumph when young parents urgently needed the Internet. The repeater did not let me down, caught the Megafon operator, and quickly downloaded the necessary information. At that moment, I felt like a magician, who, with the help of a wire frame, opens a new spring.
The mobile signal booster solves the problem of phone calls and the Internet in the country, in the garage, as well as in other hard-to-reach areas. This accessory is not cheap. The problem will be solved by a do-it-yourself gsm repeater, which will completely replace not the most powerful purchased repeater.
The repeater is passive and active. The first does not require a power connection and is an antenna that can operate independently in a small area. It is also used as part of a system with an amplifier connected to the mains.
A passive repeater of LTE or GSM standard catches the weakest signals of the corresponding frequency ranges and transmits them to devices. This is the simplest option for self-manufacturing from improvised items and materials. The downside is the lack of amplification and stabilization of mobile communications.
A do-it-yourself GSM cellular repeater operates without connecting to a gadget.
The cellular signal amplifier circuit includes:
The system allows you to improve the quality through the use of multiple antennas. Passive amplifiers are also on sale, they are connected directly to the phone with a cable. In addition to the high price, the very fact of the presence of wires restricts the freedom of movement when making calls, and the quality of communication becomes worse with each additional meter of wire.
Do-it-yourself GSM repeater video:
To make your own passive repeater, a regular wire or even a tin can will do. From the first, you can make an antenna from rings or in the form of a double rhombus.
Antenna or repeater gsm signal from wire.
Dimensions are determined by the required frequency, for example, take F = 900 MHz. The diameter is calculated according to the formula (300 / F) / 3.14, that is, (300/900) / 3.14 \u003d 0.106m. This coil is the antenna.
Antenna from one ring
Interconnected: they differ from the first option by two turns of wire instead of one, the design is made from one piece. We fix them opposite each other. The distance is calculated by the formula (300/F)/4, for the case under consideration it is (300/900)/4=0.08m. The same frequency is given, the diameters are considered similarly.
GSM antenna with two rings
Four rings: The antenna is similar to the second, only instead of turns there will be two eights. The calculation is similar to the previous paragraphs.
Diamond Amplifier: The wire is bent into a square shape, then two opposite corners are bent towards each other and fastened together. For clarity, the scheme of the gsm repeater:
Diagram of a diamond-shaped GSM amplifier
Options one through three are arranged in ascending order of signal gain. They can also be operated as independent cellular repeaters. One antenna is installed as external, the other - as internal.
For the device of an active amplifier, you will have to organize an entire installation. The collection of all the elements into one whole, clearly demonstrates the diagram of a cellular repeater for DIY manufacturing:
Cellular signal booster circuit
A full-fledged home-made gsm repeater will require, in addition to the antenna: a cable, fasteners (for installation), a 20 cm long piece of polymer pipe or a plastic can (as a connecting block), a sheet of plastic, a screen (reflective material), 2 straws.
How to make a gsm repeater with your own hands:
Now it is already quite difficult to find people who have a landline phone installed at home. This is due to the fact that all technologies are developing very quickly. Landline phones have already gone out of our lives, they are simply not needed. People use mobile devices that receive radio signals. Unfortunately, today you can find places where there is no mobile connection. This happens if there are any obstacles in the way of the signal, for example, forests, tall buildings, or just a long distance to the repeater. In this case, you can install a signal amplifier. In this way, you can improve the quality of radio reception. But how to choose a good one In this article, you will find the answer to your question.
To proceed to the choice of amplifiers, you need to determine which cellular services you need more - voice calls or mobile Internet.
If you plan to improve the quality of communication, then it is better to choose a GSM repeater. Otherwise, you need to use a good 3G antenna or a quality 3G repeater.
You also need to pay attention to what standard your operator works in. The choice of repeater will depend on this. For example, the Tele2 operator operates in the GSM-1800 standard. In this case, you need to select a suitable cellular signal booster.
Of course, there may be another situation where you need to amplify 2 signals at once. What to do in this case? Some companies produce 2-band GSM/3G repeaters. Before buying, you need to decide on these parameters in order not to regret the purchase in the future.
At the second stage, you need to check the level of the cellular signal at the moment. To do this, we take several phones and rearrange the SIM card between them to determine the exact signal level. The sensitivity of the antennas on different phones may vary, and you need to get a more accurate ratio for the cellular network booster.
How to determine the gain for a repeater?
The cellular signal booster for the home should be greater than 60 dB. Weak repeaters will not bring you the desired result. There will be a weak signal in the room and, in addition to this, a limit is imposed on the number of simultaneously talking subscribers.
You need to measure the area of the room where you need to improve the mobile signal. This parameter is also very important, since a large surface imposes an additional limitation on the output power of the repeater.
For example, if you need to improve the signal in an area of about 160-210 sq. m, you will need a conventional amplifier with an output power of about 100 mW.
When choosing an amplifier, it is necessary, in addition to all the characteristics, to look at the brand of this model. You should not save on this equipment, so you simply will not achieve the desired result. If you find a repeater that will meet all the specifications, but at a price much cheaper than the competition, most likely it is a fake. The quality of such devices leaves much to be desired, all the characteristics that are written by the manufacturer remain on paper. Therefore, it is better to choose an expensive and high-quality amplifier model than just throwing money away.
If you are looking for a high-quality and inexpensive model, you should contact domestic manufacturers. The Russian company REMO has developed the Connect 2.0 amplifier. It consists of an antenna and a modem. The price of this repeater is 1000 rubles.
Connect 2.0 is designed for 3G/4G and mobile communications in GSM networks. You can achieve not only high-quality signal amplification, but also an increase in the range of Wi-Fi.
This equipment has quite good characteristics:
The repeater of the Russian company is quite compact. The kit also includes a three-meter cable.
This signal booster for the MegaFon, MTS or Beeline cellular network is configured quite simply. If you can't figure it out, then see the attached instructions. Remember that you first need to set the parameters on your modem (it is compatible with almost all models), and only after that connect it to the antenna.
Customer reviews differ from each other. Some write that the signal has improved markedly, while others say that practically nothing has changed. You must understand that this is a budget model, and it may not meet all your expectations.
The American company Nextivity introduced a pretty good Cel-Fi RS2 amplifier. This device can not only improve the 3G and GSM signal, it is also significantly able to expand the coverage area. Manufacturers have made a unique repeater that does not require an antenna, and its connection is so simple that even a child can handle it.
The kit contains 2 blocks, which must be placed together where you find the best signal level. It can be determined using the phone or the repeater itself, moving the device around the house. The signal level can be seen on the indicator located on the body of one of the blocks when you plug it into the outlet.
On the second block there is an indication scale. It must be installed where the readings on it will be greatest. Unfortunately, this unit also requires mains power, so you need to install both units near a power outlet.
This signal amplifier of the MTS, Beeline or Megafon cellular network, although installed without an auxiliary antenna, copes with its tasks. This is a pretty good and high-quality model that provides a high signal level. Of course, there is a noticeable minus here - this is the price. Nextivity Cel-Fi RS2 costs about 40,000 rubles. Because of this, this repeater is usually installed in offices, and not in private homes.
Only positive reviews can be seen about this amplifier. And this is normal, since an expensive foreign model does an excellent job with its functions. People praise this device, but the only problem is the price.
TAU-2000 is a good cell phone signal booster that supports major Russian operators. This equipment is presented in the form of an antenna and an external unit to which a smartphone or modem is connected.
This model is usually used for large rooms, as it has a fairly large output voltage. If you caught the average signal from the base station, then this receiver is able to improve it and transmit it to a distance of about 100 meters.
Of course, TAU-2000 can be used for both home and car. The coverage area will be closely related to the quality of the input signal. With a good connection, about 15 m 2 can be covered. The price of this receiver is 13 thousand rubles.
Before buying, you can consider the reviews about this device. Users mostly leave a lot of positive comments and only a few negative ones. This indicates a quality amplifier that is worth buying.
A quality receiver will be quite expensive. If you really want to improve the signal, then you should not skimp. When choosing an amplifier, pay attention to the characteristics, a lot will depend on this. If you need to cover a large area, choose a receiver with high output power. Remember about the gain factor, on which the signal reception will depend. You can also make your own cell phone signal booster. In this case, you will need to select the material based on your needs, and proceed to work. If you do everything right, then its characteristics will correspond to the budget model.
Is it necessary to purchase an expensive gadget when it is possible to get by with a device assembled from improvised means?
Those who have at least an initial level of knowledge in the field of cellular communications will be able to cope on their own. This requires components and tools, as well as a device diagram.
And you can assemble the simplest cellular amplifier on your own. What is required for this will be discussed below.
They are one of the simplest devices that allow you to achieve a high-quality signal on any object.
There are two main groups of antennas:
The former are usually installed on the roof of a building and are capable of providing coverage over large areas. The signal received from the base station is transmitted by the antenna through the cable to the amplifier. This guarantees good communication quality even in areas where it was previously impossible.
It is possible to provide reliable communication in hard-to-reach places for a radio signal, but this will require special equipment. Various devices assembled into a single system make it possible to achieve high signal quality and forget about its sudden disappearance forever. It is often referred to as a cell phone booster. However, in fact, it is a complex consisting of the following elements:
All devices included in the system are divided into two groups:
The first includes devices for which operation requires a connection to a power source - this is a repeater, connectors. Antennas, a divider and a cable are called passive. Each system is calculated for a specific object and therefore may have a different number of amplifiers and internal antennas. The best option is one that uses a minimum cable length, since each extra meter of it is a loss in signal quality. This must be taken into account when assembling a cellular signal amplifier with your own hands.
Since all elements are interconnected, it is recommended to install the equipment before finishing, so as not to spoil the interior.
The equipment of this class is in some way a repeater. It processes the received signals and sends them to the base station tower if it is an outgoing call. When a subscriber is dialed, the repeater performs the same function, only the connection is made with the user's gadget.
Watch the video, the simplest way to amplify the signal:
The signal is received and transmitted by antennas. The simplest cell phone signal booster can be assembled by hand. The outdoor antenna receives or sends it to the station, while the indoor antenna is responsible for expanding the coverage area in the room.
The use of such a device allows you to achieve high-quality communication in almost any corner of the object. A repeater is especially needed in areas with a poor signal or where it is absent. The advantages of using the system include such features as:
But since such equipment is not cheap, many decide to make it on their own.
Watch the video, do-it-yourself manufacturing steps:
In order to assemble a cellular amplifier on your own, you will need components that need to be connected into a single system. How to do this will be discussed next.
If you decide to make the simplest device, namely an antenna, then you will need:
Since in the process of work you will have to connect individual elements, it is worth having electrical tape on hand. After all the components are found and prepared, you can start assembling the cellular signal amplifier with your own hands.
A piece of wire must be bent in the middle by 90 °, so that the result is a rhombus. To do this, retreat from the center by 9 cm in both directions. Then, at the mark, the wire is again bent at the same angle. As a result of the manipulations, you get a rhombus. The ends are bent inward and a block is connected to them. Install it so that in the future you can connect through it. For this, a polymer pipe is cut along one side and a hole is made opposite.
We watch the video, we make an amplifier from cans:
After the antenna assembly stage has been completed, they begin to connect the coaxial cable. At one of its ends, the outer insulation is removed and the outer and inner conductors are connected to the contacts of the connecting block. As a result, the cable becomes a continuation of the antenna.
After that, it remains to install the device on the roof of the house or attach it to a pole and direct it towards the base station of the mobile operator. The last step in making the simplest amplifier with your own hands is to connect the other end of the cable to a plastic plate. And you can start testing.
If everything was done correctly, then as soon as you bring the mobile phone to the amplifier, the signal indicator will increase by 2 or 3 divisions.
But it’s not enough just to assemble a cellular amplifier, you also need to correctly install it. The efficiency of such equipment is directly dependent on its location, as well as the antennas included in the system. Therefore, before proceeding with the installation, you must make sure that the signal level is sufficient. The easiest way to find out is by making a call from the phone where the antenna is planned to be installed. You can also determine the signal level by the indicator on the gadget's display.
Antenna Installation
But besides this, there are other limitations. For example, the place for installing the amplifier should not be closer than a meter to the heaters.
After planning the location of all components, they begin to lay the coaxial cable. But before turning on the repeater, you need to make sure that all connectors are intact and clean. Do not turn on the device if it is not connected to an external antenna, as it may be damaged. If you need to disconnect the RF cables, be sure to turn off the power.
There are also temperature restrictions. If for an external antenna it is from -40 to +50°C, then for the repeater itself it is limited only to positive temperatures. In addition, the repeater can only be installed in a heated room.
Need to remember! An incorrectly assembled system is capable of emitting interference, which affects the operation of nearby stations. Therefore, you should not install it without surveying the object and determining the location for placing all the blocks.
In order to obtain a stable and sufficient communication signal at a particular facility, it is necessary to correctly perform all commissioning work. They consist in setting the quality of voice messages and excluding self-excitation of the device.
We watch the video, what to do if the signal is bad, we watch the solutions:
The first thing to start with is to make sure that all connections are intact. The power adapter and antennas are connected to the high-frequency connectors. If power surges occur frequently in the network, then a surge protector must be used.
The next step is to adjust the gain. It must be at least 15 dB. The repeater can be configured manually or automatically. In the first case, the adjustment is carried out using the potentiometer knob and changing the position of the external and internal antennas.
Auto tuning involves setting the gain level so that maximum output power is obtained. In this case, the device will independently adjust to the traffic of the operator's base station.
Have you encountered the fact that it is impossible to get through to your parents living in the country due to problems with cellular communication?
With the impossibility of full communication with friends via Skype or the Internet?
Despite the optimistic statements of mobile operators, some villages are still in the "zone of uncertain reception".
In search of a solution to this problem, I looked through all possible options for accessing telephone lines - it turned out to be extremely expensive.
I didn't have such a service nearby.
Satellite Internet and communications also cost a lot of money, both equipment and maintenance. As a result, I came to the conclusion that the most affordable option is mobile communications and the Internet, which is present in the basic configuration of any tariff of any mobile operator. In the electronics market, I was advised to buy GSM signal booster.
The GSM signal amplifier consists of an external antenna, a cable from the antenna and an internal translator unit.
Almost all the samples on the market are similar in terms of their work, I found differences only in the level of signal increase, size and, of course, budget.
The principle of operation of these installations is simple - an antenna aimed at a more or less confident signal collects a beam of waves from the nearest cellular repeater. And, increasing the signal strength, transmits it to mobile devices.
According to the descriptions, all amplifiers operate within a radius of 10-15 m from the installation site and can provide reception to 5-7 devices simultaneously. To put it simply, a cellular amplifier is your personal repeater in your home.
Having bought one of these amplifiers (I chose one of the budget options) and seeing that in the installation you only need to put an external antenna and plug the amplifier into a power outlet, I set to work.
Installation with slow and careful work (without drilling walls and laying in cable channels) took us about 45 minutes, but ... After many attempts, we could not catch a relatively good signal.
I had to install a free program on my smartphone that measures readings and signal strength. With her, everything became simple and clear: point the phone in any direction - and analyze. Is there a signal? Point the antenna and check the level near the amplifier block.
Now let's talk about the results. Standard in our area, the phone received 3 towers with a maximum indicator of -109 (red sector). After turning on the block, the phone showed 6 towers with a level of -69 (in the green sector). To put it simply, the signal level from 0-1 reception divisions (out of 5) became confidently 5 out of 5.
Perhaps someone will say: Why all this, because you need to relax in nature? But more than half of our dacha neighbors are interested in this issue.
As for costs, my installation costs an average of 5 to 7 thousand rubles. This is a Russian development, there are more expensive ones, but, according to reviews, they do not work much better. In my opinion, it is better to put a more or less average amplifier unit, but the antenna is larger, not 30 cm, like mine, but from 50 cm and more.
On a note:Mobile communication in the country - stable and without interference: installing a repeater
The information society puts forward the requirement for a person to be always in touch. But even the most modern mobile technologies are not yet able to completely entangle the vast expanses of Russia. So, if you have problems with mobile communications in your country house, you need to take the solution of this problem into your own hands!
Before talking about the process of improving the quality of mobile communications, some technical aspects should be clarified. Modern mobile networks operate on several generations of global standards. The most common mobile communication standard is GSM (Groupe Special Mobile), which belongs to the second generation of mobile networks (2G). The basic principle of its operation is the separation of data streams by time and frequency (TDMA and FDMA, respectively).
Gradually, 2G, including GSM, is being replaced by new generations of mobile networks - 3G and 4G. An innovation introduced by AP networks is the use of separation of information flows by code. Simply put, each subscriber receives a code that goes to the operator's server, which, in turn, transmits the required data streams in the opposite direction.
Data in all cases means both voice or text information, and, say, codes of Internet resources.
Most likely, in order to improve the quality of mobile communications in the country, you will have to deal with GSM. Please note that you will not be able to catch 2G and 3G at the same time with the same equipment. If you definitely need the Internet, it is better to pay attention to 3G. And do not forget that not all phones support new generations of mobile networks, while GSM has been and remains the standard for all phones.
Theoretically, the signal from the base stations should extend to a distance of up to 35 kilometers outside the city. In practice, this is not always the case - the signal can be reflected from hills, tall trees, various metal or reinforced concrete structures. Each time, reflected from the next obstacle, the signal loses power. Thus, white spots appear on the maps of mobile reception areas. Cellular operators usually try to solve this problem by installing additional base stations or strengthening some station already deployed in the area.
THIS IS INTERESTING!
The G5M standard is by far the most common not only in Russia, but throughout the world. Now it accounts for about 80% of the global market for mobile services.
Don't rush to pay
Preliminary study the coverage map of different operators. It may turn out that your current operator does not cover this area well, while the connection will be excellent with another. In this case, it will be both more economical and less laborious to switch to it. If this option is not suitable, then strengthening the connection comes into play.
So, what will you need to purchase to amplify the mobile signal? Firstly, these are external and internal antennas. Secondly, you definitely need a repeater - a signal amplifier that transfers the signal from the external to the internal antenna. The external antenna is connected to the repeater via a 5D-FB coaxial cable - this cable provides a significant reduction in losses and good signal shielding when transmitting a signal in the required frequency ranges.
The cable must be connected using an N111/5D plug. It should be noted that one repeater, if your dacha occupies a large area, will not be enough for reliable signal reception throughout the entire area. Then, most likely, you will have to install a few more repeaters. When choosing equipment, be sure to correlate its characteristics with the frequencies at which your network operates and with the desired effect: pay attention to the declared output power and signal gain.
Before installing the equipment, you need to find out where the nearest base station is located. This can be done at the operator's offices or on the Internet. Pre-explore the space of your cottage. The antenna should be directed towards the base station from which you receive a signal.
Mounting hardware is usually included. An outdoor antenna is usually attached to a wall or roof with anchors. If trees grow around the cottage, tall buildings or hills are located, it is advisable to mount the antenna on the mast. The repeater, whose location should ideally coincide with the approximate center of the room, is attached to the inner wall of the building using dowel-nails (there must be a separate outlet nearby to power it).
The repeater is connected by a cable to the internal and external antennas. After that, the repeater must be tuned to the network frequency. There is nothing complicated in the matter of installation and configuration, but if the connection is not made correctly, you risk even more significant deterioration in communication.
I must say that mobile communication amplification systems are an inexpensive thing, but many of our fellow citizens cannot always afford it. In order not to overpay, always measure your needs with one or another means of amplification - do you need an expensive multi-repeater system?
There are also situations that even installing additional equipment for receiving a signal does not solve the problem. If you have a lot of neighbors in the country, whose mobile catches just as badly, then it is rational to contact the mobile operator together. More than once there have been situations when, in such circumstances, the operator, at his own expense, with the involvement of specialists from his technical departments, solved this problem by installing a new base station or strengthening an existing one. The more people who apply, the higher the chances that the appeal will be heard!
