Strengthening the 4g signal in the country with your own hands. How to improve Internet reception in the country. Antenna testing in the field

Content

All mobile operators that offer Internet access via the 3g network (MTS, Megafon, Beeline, etc.) have a certain coverage area. If you are behind it, then the Internet connection will be very weak, the connection will be unstable, the speed will be low. In such cases, you can use options that will provide amplification of the 3g modem signal.

How to amplify the signal of a 3g modem using speakers

The first option, how to amplify the signal of a 3g modem with your own hands, which you can try at home without any extra spending and effort, is to use ordinary speakers. Users mobile internet noted that if you move them closer to the modem, the signal level increases by 10-20%. This is not very much, but with poor communication quality it gives a noticeable increase. To get rid of annoying clicks from the speakers, the volume should be set to a minimum.

Signal booster for 3g copper wire modem

Another way to easily amplify the 3g modem signal with your own hands will require you a little more action than the speaker option. You need to make a structure out of wire and a tin that would act as an antenna. The algorithm of actions is as follows:

Take copper wire (preferably a long piece).

1. Open the gadget and make 5-6 turns around the SIM card.
2. Pull the other end to the window.
3. Take a tin can or cut off the neck of a beer to make a "glass". It will act as a reflector that enhances communication.
4. Tape the free end of the wire to the bottom of the can.
5. Rotate the neck towards the nearest operator's tower. The increase in the quality of the Internet will be up to the level of 90-95%.

How to strengthen the signal of a 3g modem with network settings

Before you make antennas with your own hands, you should try another method, how to enhance the reception of a 3g modem signal. Some mobile Internet users do not know that by default, with a low connection quality, the device automatically switches to 2g communication mode, with which it is not possible to work normally. In this case, the transition occurs even in the presence of 2-3 "sticks". To avoid such situations, you should clearly indicate through the device settings that only a 3g connection should be used. How to change an option:

run the network setup program;

1. select the "Connection" tab (or with a similar name);
2. then the network search mode needs to be changed from automatic to 3g.

This will force the device to work only on those frequencies without dropping the connection to a slower one. Some modems do not have such an item in the application interface for the device. In this case, you should look for a combination to activate the built-in command in the instructions for the device or on specialized forums. For each modem model, its own order of enabling the option is programmed.

Strengthening the signal of a 3g modem with a USB extension

This is not the best, but a working way, how to easily amplify the 3g modem signal with your own hands. Suitable well for people who do not want to disassemble, solder their device. The design works on the principle of a satellite dish. To make it, you need to buy a “reflector” (a jar, a bowl, a CD), a USB “mother-dad” cable 3 meters. The creation process is as follows:

In the middle of the disk, make a mount for a flash drive, or tape it with tape.

1. Connect the cable with one end to the computer and the other end to the modem.
2. You can use a stick instead of a holder or simply fix the disc from the side of the street to the facade of the house.
3. Point the flash drive in the direction where the signal is strongest.

The increase in communication quality is not very large, because the usb cable loses some of it due to its length, but it still improves the connection. The mirror surface of the CD acts as an amplifier. It is recommended to use a bowl instead of a disc because its reflective surface is larger and the reception will be even better. Enameled options are not suitable, use stainless steel products.

Special external signal amplifier 3g modem

Operators are aware of communication problems, so they are constantly trying to expand their coverage area. As an intermediate solution, for example, a 3g signal amplifier was created for the Megafon modem and other companies. This is an antenna that operates at the required frequencies, and you need to connect it directly to the device. When choosing a model, one should rely on the indicators of the radiation pattern and gain.

For effective work antennas, it must be directed towards the tower of the mobile operator, which is closest to your home. Attach the stand so that the pins are perpendicular to the ground. Please note that the longer the cable length, the greater the signal loss along its length. A short cord will provide enough connection gain if the cord is of good quality. If you bought an amplifier, then you should not save on the cable.

How to strengthen the 3G signal with your own hands using a repeater

The most effective is amplification using a special device - a 3G repeater. Amplification is possible only if the phone catches at least a minimal 3G signal. This approach can be called fully professional, because after installing the repeater you will receive:

the maximum possible amplification of the 3G signal;

• the maximum speed of the mobile Internet, which the mobile operator is able to provide;
• stable reception area within the coverage radius of the internal antenna;
• getting rid of problems that arise with a weak signal: communication breaks, subscriber unavailability, interruptions during a conversation, and others.

The easiest way to strengthen the Internet in the country is to install a router with an external antenna.

In most cases, problems with the Internet in the country are associated with remoteness from the base station of the cellular operator or obstacles (natural and artificial) in the path of mobile signal propagation. Strengthening the Internet in the country is very simple. To do this, there are special sets of equipment that can be divided into two main categories.

Most often, to amplify the 3G / 4G Internet in the country, a passive amplification kit based on a modem / router and an external antenna is enough. An external antenna is installed outdoors, directed towards the base station of a mobile operator and connected to a 3G/4G modem or router. The SIM card is installed directly in the modem or router. Mobile Internet is “distributed” to other devices via WiFi or through a wired connection.

Advantages	Flaws
low price The cost of the kit - from 4900 rubles.	This type of kit provides 3G/4G internet boost but does not improve the quality of voice calls from a mobile phone.
Ease of setup Install the antenna correctly, connect it to a router or modem - and that's it, the setup is complete!	The router requires a separate SIM card Because the amplified signal goes directly to the 3G / 4G router or modem, they need to install a separate SIM card.
Support for all operators 3G/4G routers and modems in our kits are not tied to a specific operator, and you can install any SIM card in them.
WiFi zone at home with the possibility of expanding to the entire site WiFi networks are very easy to expand by installing inexpensive additional access points

Popular Models:

The second type of kits uses an active cellular signal amplifier - a repeater. It receives a signal from an external antenna, amplifies it and then transmits it to an internal - distributing - antenna. The internal antenna emits an amplified signal, providing high-quality voice communication and mobile Internet throughout the premises.

Advantages	Flaws
Support for all operators The repeater amplifies all signals in a certain frequency range and thus is not limited to one cellular operator.	higher price The cost of the kit - from 11900 rubles.
Each user has their own SIM card Since the amplified signal is distributed throughout the premises, users can use their smartphones and other devices without any restrictions.	As a rule, the range of a repeater is less than a WiFi router

Internet access is necessary for every person for work, study or for their personal needs. The mobile phone does not always pick up the Internet. Not everyone knows how to amplify the 3g signal of a smartphone.

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

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

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

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

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

Software settings

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

Configuring the program for amplifying 3g and 4g

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

1. enter the application and grant superuser rights;
2. if the device is rooted, enter ApplyPatch, reboot. The Internet signal booster on the smartphone will work;
3. if the user does not have superuser rights, enter ImproveInternetConnection, then reboot the device.

This method does not work on all devices, so it is recommended that you first get root rights in order to surely increase the 3g signal on your smartphone.

If the user wants to restore the old settings, it is recommended to enter the menu, click "Restore", confirm their actions by selecting the "OK" button.

Hardware improvement

You can strengthen the cellular signal on your smartphone by purchasing additional devices in specialized stores - a repeater and various kinds antennas. Such devices significantly amplify the signal coming from the operator. In this situation, no manipulations with the device files are required.

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

It is now the middle of spring, which means that the summer season will soon come. However, for many, going to the country is like being on a desert island: nature is all around and ... not a hint of cellular communication. And you can forget about the Internet in general.

This occurs all the time in the vastness of our country, but, fortunately, it is not fatal. Any local telecommunications company will be happy to relieve you of information hunger “for just some” 50,000-100,000 rubles! Do you think such spending is unreasonable? Me too, because they can be reduced by more than 10 times! Cellular and Internet amplifiers for summer cottages cost around 3,000-15,000 rubles, and you can easily pick up and install them yourself.

Types of amplifiers

Devices for cellular communication (GSM) are called GSM repeaters or repeaters. More precisely, this is not one device, but a complex of equipment, consisting of:

• A directional external antenna that picks up the base station signal.
• Coaxial cable for connecting the antenna to the signal amplifier.
• the amplifier itself.
• Amplifier power supply.
• Internal omnidirectional antenna.

An external antenna is placed outside the house in the place of the best visibility of the operator's base station. The amplifier is fixed on the wall inside the room and the internal and external antennas are connected to it.

3G/4G Internet signal amplification devices consist of one or two modules. One of the parts of two-module amplifiers works to receive a signal, the second - to create a coverage area inside the house. Both parts are connected by cable. The receiving module, as well as the antenna of the GSM repeater, is located outside; coverage module with a connected USB modem - in the room.

Single-module amplifiers are conditionally divided into 2 types - internal (for indoor use, more precisely, on the table) and outdoor. The internal ones are a kind of shield that protects the USB modem connected to them from interference, helping it to receive a signal only from the base station. Such devices operate in wide frequency ranges, but their gain is not very high.

An outdoor amplifier is essentially an antenna, which is also installed outdoors in the zone of the best visibility of the station. A cable is attached to the antenna, the second end of which is inserted into the USB modem jack, and the modem itself is connected to a computer or router. Such devices amplify the signal 1.5-2 times better than internal ones, but, as a rule, they work in a narrower range.

In addition, all such devices reduce the radiation level of modems and telephones (the lower the signal, the stronger it is) and reduce the energy consumption of their batteries.

How to choose equipment

Before buying a GSM repeater and mobile Internet amplifier, carefully study their characteristics. There is no such devices that are suitable for absolutely everyone, because the conditions in which you will use them are absolutely unique. What works well for your neighbor may not suit you at all, and vice versa.

So, when choosing equipment, you should first look at:

• The range of supported frequencies. Most Russian cellular operators work according to the GSM 900, CDMA and UMTS (3G) standards, which they are guided by domestic producers repeaters. And if your operator broadcasts on GSM 1800 (in particular, Tele 2 uses this range in many regions), the device will be useless for you without its support. The same applies to 3G/4G communications.
• The distance of your cottage from the nearest base station. This can be found out by calling local operators or using programs that show their location on a map. Here are 3 examples of such applications for Android: Antennas , networkcellinfoLite , OpenSignal Maps 3G/ 4G/Wi-fi connections . The closer the tower is to home, the better the reception quality can be achieved. Stations located further than 10-15 km can not be considered. If your operator's tower is relatively far away, you can either buy a SIM card from another company for giving, or choose a more powerful one. In general, the power of any device for a country house should be at least 100 mW.

• The signal level of the operator in the area of ​​the planned installation of the antenna must be at least one bar. This is easy to determine using a mobile phone with a SIM card or a laptop with a connected 3G / 4G modem and a program for managing this modem. Or, for example, utilities Mobile Data Monitoring Application(MDMA), which shows more accurate results and supports almost all models of 3G modems. You will need the same tools to set up the antenna and choose the location of the amplifier in the house.

• The area of ​​​​the premises of the house, the material of the walls. This is important when choosing the power of the internal amplifier and the "range" of its antennas. For a house with more than 2 rooms and a brick wall, the internal antenna gain should be at least 3-5 dB.
• The number of subscribers who will be connected at the same time. The majority of GSM repeaters support up to 4-6 simultaneous connections.

What else it is desirable to pay attention to when choosing an amplifier:

• If you have never done manual tuning of such equipment, choose devices that control the amplification system automatically.
• The cable connecting the outdoor and indoor units or antenna and modem must not be excessively long. The shorter it is, the better the signal. The optimal cable length is up to 5-6 meters, but if the manufacturer has equipped the device with a longer one, then its capabilities allow this.
• Some manufacturers indicate on the box that the embedded cable has a resistance of 50 ohms, and this is supposedly its advantage. In fact, this is pure marketing. The signal loss of 50 ohm and 75 ohm cable is almost the same, but the latter is much cheaper.
• The set of equipment must contain all the necessary adapters, in particular, with a CRC9 connector for connecting to a USB modem.

• Do not buy GSM-repeaters, the internal antenna of which is inseparable from the body of the device. This will not allow you to install both in different places in the house and will not give you the opportunity to create a sufficient coverage area.
• When choosing a store, give preference to the one where they agree to exchange or take back the purchased equipment if it does not suit you.

How to install an amplifier

Installation of GSM repeaters and outdoor Internet amplifier antennas usually does not present any difficulties, especially since almost all of them are provided with installation and configuration instructions. The most difficult thing you may face is the need to climb on the roof, because the higher the antenna, the less interference.

The outdoor antenna should point towards the base station. The optimal location of the repeater and internal antennas is determined experimentally - according to the signal level on the phone, however, they must be no closer than 3 meters to the external antenna.

It is better to use single-module desktop 3G / 4G amplifiers near the window from the side of the tower. The device should be deployed so that the modem is facing her.

With exotic plants and suffocating heat, others prefer a mild summer among their native birches and pines 🙂 To each his own, as they say. Rest in the country or in the village attracts many. First of all, for the lack of fuss and minimal communication with the outside world. But the global network is firmly seated in our brains, and social networks leave no chance to sit out in the wilderness.

This is where the problems begin. The quality of cellular communication is only in words perfect. We drive two or three dozen kilometers from a large city, and problems begin. The question arises: "How to improve the Internet in the country?". You can not bother and sit without likes, reposts and other nonsense. On the other hand, why not try to deal with the problem yourself?

INTERESTING. The first attempt to make a mobile telephone was made by the New York Police Department in 1921. A little over a decade later, police cars were equipped with two-way telephone radios. In the USSR, the first prototype of a mobile phone was made in 1957. It was called LK-1 and weighed three kilograms.

Before improving, you need to understand what kind of connection is possible in principle. As a rule, there are two options: Internet via satellite or via a cellular operator. The trouble is in the price of equipment and satellite Internet tariffs. Few people want to pay about 20 thousand for equipment and 3-4 thousand for using the service. Moreover, the speed, although good, is not super - within 20 megabits.

Amplifying a cellular signal is technically feasible and cheaper in terms of money. We buy an antenna, install and enjoy the benefits of civilization 🙂 But! You need to choose the right amplifier. Yes, and setting up the equipment is not so simple. Before making a decision, let's try to understand not only the cost, but also the labor costs. Because it’s not a fact that we can do everything ourselves, but calling in specialists means paying money.

Internet amplifier. Dreams and reality

Let's start with the definition of needs. How much traffic is enough per month? What speed is needed? Watching videos, surfing of course, possibly downloading torrents, well, network games. If you start counting from the friezes, then the speed is needed within 5-15 megabits. If more, even better. A channel at the level of 2-3 megabits is enough, but you can forget about downloads.

You can sit and count the traffic. On average, it turns out in the region of 15 gigs. On average, this is between needs. Someone watches movies more often, others download more, others play. So you need to choose a tariff with more daytime traffic and nightly unlimited. And then we will deal with the "technique". Both satellite and cellular, this is not a cable for you. There are many more problems - interference, thunderstorms, narrow channels in rural areas.

Strengthening the cellular signal in the country

All subsequent material is of interest to those who decide to strengthen the reception of cellular communications. Yes, yes, let's not even talk about the satellite. Firstly, it's a little expensive, and secondly, you can't do a damn thing yourself. And we proceed ... and start by choosing an operator. It doesn't matter what you use in the city. A village is a village.

IMPORTANT! The main reason why satellite Internet is used is the inability to provide the service in another way. Most often, the equipment is installed on the "last mile", that is, directly at the client. main feature such access is the division of traffic into input and output with subsequent combination. The technology is called asymmetric access. Reception via satellite, return via cellular.

First, let's look at coverage maps on the websites of operators. But, we don’t trust them much - they are for those who definitely won’t get a connection 🙂 Have you estimated your location? Now we open maps from Google or Yandex. Define the house accurately. It remains to compare the location with coverage areas. maybe locality will be overlapped by multiple operators. We choose the one whose territory is larger, the signal quality will be better. If this is not done, it may turn out that a 4g signal amplifier is not needed for giving.

How to strengthen the cellular signal in the country

There are entire threads on thematic forums where methods for finding the right cell are discussed. What for? “Air” differs from cable in that any uneven terrain affects both the signal level and the speed of the Internet. You can walk around the neighborhood with a beech or a tablet, entering trace data on the map 🙂 But you can make it easier. We find a simple antenna, fix it on a pole and raise it above the ridge of the house.

Antenna to the modem, and that to the computer. We launch the MDMA program and turn the device on the roof. We do this slowly, constantly fixing the signal level. Out of habit, you will have to spend half an hour or more. As a result, we get several directions that give the best signal. We choose the most powerful. Here we will direct the antenna to it. If you are thinking about buying an amplifier, look at the performance characteristics. It may turn out that the increase will not justify the money spent.

INFORMATION. Repeaters are called repeaters and amplifiers of a cellular signal. Devices are used to expand coverage areas. In the general case, this is an actively operating radar equipment that operates in conjunction with an antenna and cables. . A cellular amplifier for a summer residence can be installed without agreement with the operators.

It remains to decide on the height to which the antenna will have to be raised. To simplify, you can use the services "Ubnt" or "Linktest". Let's say right away, do not take the learned data for granted. According to calculations, it turns out that a height of 20 meters is needed, but the really high-quality reception is at 7-8 meters. Another tip - do not try to get the speed, like in the city. The maximum for summer residents is 20-30, sometimes 40 megabits.

And the last one in this section. Doing the right thing 🙂 calculations, a long choice of antenna, actually hand soldering, a height of 15 meters, you will get a gain in the range of 95-98 percent. If you buy a ready-made, not the most sophisticated, antenna, install it above the ridge with an approximate orientation, you will get a signal amplification of 70-80 percent. The result is good, less money and effort.

Antennas to amplify the Internet signal

In a good way, amplifying equipment should be selected simultaneously with the search for a confident signal. It is better to immediately pick up a set of antenna, mast, bracket, cables and other bells and whistles. This is the only way to understand what effect the actions will give. And that's not all the problems. How do you like the situation when the antenna operates on one frequency, and the base station on another? You can’t find out the information from the operator, it’s easier to split partisans during interrogation 🙂

Now about the form. It is not necessary to order some special model from the other side of the planet. Do you sell panel antennas nearby? Here, take it. They are slightly weaker than the "beam" ones, but they do not need precise directionality. And the range is much wider, which is only a plus. It's a great help to switch between 3 and 4 G. Why? 🙂 It's better to surf on a four - the browser just flies, but downloading large volumes - 3 G is beyond competition.

Antenna calculation for amplifying a cellular signal

It is doubtful that there will be many willing to make calculations. But let's give a table that you should be guided by.

This is necessary in order to mount the antenna, not to remain with the same signal level. Roughly speaking, we were looking for a direction with a device with a gain of 12 dB. Found the direction in which the signal is -90 dB. Cable and connections eat about 3 dB. Accordingly, after all the "dancing with tambourines" we get a signal level of -99 dB. Mediocre, however. And you need to get at least "good". So it turns out that you need an antenna with a gain of 20 or higher.

DID YOU KNOW…how cell phone base stations are built? The first section is put up by a team of 5-8 people and a truck crane. The next day, four more sections are placed by helicopter. Then, from two to three days, they are engaged in “broaching” the support shaft. Then they improve the territory - they put up a fence, install a drainage system. Only after this, the installation of the BS begins - the installation of sector and radio relay antennas, and other devices. Then electricity is supplied, lightning protection, light protection and grounding are mounted.

We will not powder our brains with evidence and calculations that determine the choice of configuration. Disputes on this topic have ended even in specialized forums. It has been proven that with uncertain reception the best option– narrowly directed MIMO. Among the positive aspects is a good increase in the speed and quality of the connection. The only negative is that you need a modem with two antenna connectors.

How to strengthen the Internet signal in the country. Choosing a router and cable

Here, with which there should not be any particular problems, it is with a router. There is only one requirement - the device must be compatible with 3 and 4 G. And, of course, a larger list of supported modems. There is less chance that yours will not be included in this number 🙂 By the way, there may be problems with unlocked devices. Therefore, it is better to buy a universal modem than to try to “flash” it on all operators yourself.

We do not discuss independent crimping of the cable. Appropriate knowledge and skills are required. And for those in the know, advice is not required. But even with a ready-made kit, difficulties can arise. You can calculate the losses and choose the right cable. That's just the price is unlikely to please. So that leaves just a couple of options. Losses can be avoided by using a short coaxial cable.

After all, it is enough to bring it to the second floor of the cottage or to the attic. And here we mount a router with a modem. Further, as your heart desires, at least wi-fi, at least twisted pair. This option is very good - usually a piece of 4-5 meters is enough. The maximum loss will be in the range of 2.5-3 dB, which is good. You can make a "knight's move" 🙂 Buy an antenna with a built-in modem. In the same office, we order a usb cable of the required length. And no troubles with losses.

We calculate the length and pull the cable to the router. Those who wish can suffer - make the cable themselves. Nothing at all. Yes, and you can get by with a piece of twisted pair and adapters. But why? Not such an expensive purchase, compared to the rest of the kit. We almost forgot about the minus of such antennas - we wanted to change the SIM card, we climb onto the roof. Although it is unlikely that you will do this very often.

How to mount a cellular signal booster for a summer residence

It is time to comprehend and sum up what was said above. So, we mount the antenna in a place that corresponds to the following parameters:

• Max Height. You don't have to become an equilibrist. Height is tall, and safety comes first;
• The less cable, the better;
• Strength. The larger the area of ​​the antenna, the more likely it is to be blown away by a gust of wind.

IMPORTANT! For almost 20 years, scientists have been “breaking spears” in disputes about the dangers of cell phones. Despite the fact that WHO has classified radio emissions from mobile phones into group 2B - a potential carcinogen - there is no 100 percent data on this. The number of studies is approaching 15 thousand, but it was not possible to identify a direct relationship between the occurrence of tumors and the use of cell phones.

Don't take advice literally. The maximum height does not mean installing a separate 30m mast 🙂 Same with the cable. Bringing into the house a loose concept, you can stretch it through the whole house. What a reduction in footage. And so in everything. We advise you to reasonably approach the selection and installation of any equipment. The result should please, and not cause additional problems.

Amplifier of a signal of the mobile Internet for giving. lightning protection

It seems that everything has been calculated, everything has been thought of. Time to mount. But no, they forgot about one problem. The higher we raise the antenna, the greater the chance of a lightning strike. You know, we are building such an excellent lightning rod 🙂 The situation only seems ridiculous. The reality is that you can quietly build the highest point in the district. Naturally, it’s not a fact that you won’t be so lucky. But why take the risk?

We made a 3g amplifier with our own hands, but got burnt electronics throughout the house. No, it's not for us. There are several solutions. You can get confused with full protection. In fact, this is VERY well worth it. Ten times less was spent on amplification. Another option is everyday ways:

• Do not raise the antenna too high. Let the signal improve by 80% instead of 100, but the lightning will not shy away;
• Planning trips longer than half a day? We pull out the cable from the modem, turn off the router;
• If you are leaving for a long time, it is better to de-energize the building. Naturally, we leave an empty refrigerator 🙂 Those who set the house under protection will have problems;
• A thunderstorm has begun - at least we pull out the antenna cable;
• Do not try to build lightning protection yourself. The result may be the opposite.

Internet signal amplifier in the country. What is the result?

It remains to answer main question: "Really get a decent Internet in the country?". The answer is unequivocal - there will be high-quality Internet! The final cost will not hit your pocket so much if you think about it before the summer season. With rare exceptions, it is realistic to meet 10-13 thousand. If the router, modem and SIM card are available, the total is less. In addition, there are sales, promotions and other options to save money.

In this layout, we do not count the ladder, screws, screwdriver and pole 🙂 Real men always have a tool at hand. In extreme cases, there are good neighbors, good friends or relatives. So getting a signal improvement from -110 dB to -90 is quite simple. And money is not the most important thing - you need desire, patience and time. For sim good luck!
