Reasons for a weak 3G signal

All cases of weak or uncertain 3G signal reception can be divided into two large groups. The first and most obvious is the user's distance from the base station (tower) of the cellular operator. The second case is a decrease in the quality of communication indoors.

Most often, this problem occurs outside cities: in rural areas, in summer cottages and in other places located on the border of 3G coverage. In addition to the distance to the tower, the landscape also plays a negative role: differences in height, forests and other obstacles reduce the quality of the signal, so that it reaches the user in a significantly weakened form.

In turn, the line of sight of the base station or long flat areas of the landscape are factors favorable for the propagation of radio waves. For example, a forest belt reduces the signal quality, but the presence of a lake, river or field behind it is much preferable to a continuous forest extending all the way to the tower itself.

Reinforced concrete structures and walls, floors and even window panes have an extremely negative effect on signal strength. As a result, even in the city center, the connection can easily weaken or completely disappear if you go down to the underground parking or enter an office building. Even if on the street mobile devices pick up 3G perfectly and show all five sticks, in buildings and premises the connection quality may turn out to be unsatisfactory.

In all these cases, additional signal amplification is required to ensure a stable connection and increase the speed of the Internet. It is important to remember only one thing: in order to amplify the signal, it must be present at least at a minimum level in the planned installation site of the antenna. It is impossible to amplify a signal that is not there, and you need to start preparing for strengthening communication by looking for a place with the most reliable reception.

Frequencies and standards of 3G communication

Before you start enhancing mobile communications, you need to understand what kind of signal you plan to amplify. All radio equipment - from simple antennas to repeaters and boosters - is designed for specific frequency ranges. Some devices support more bands, others less. There is usually no need to amplify all existing radio frequencies: it is unreasonably expensive and simply unnecessary. It is much more efficient to find out exactly which frequency ranges you need to work. This will allow you not to buy universal expensive equipment and limit yourself to specialized devices that are suitable specifically for your case.

The vast majority of 3G base stations in Russia operate in the 2100 MHz frequency range. The 3G standard corresponding to this band is commonly referred to as UMTS-2100. Both voice communications and mobile Internet are transmitted over 3G networks, so amplification of the frequency range of 2100 MHz is most often the best solution.

Since modern smartphones automatically select the preferred communication standard, they often jump between 2G and 3G modes in situations of poor 3G reception. This behavior leads to interruptions in voice communication and unstable Internet operation. As a rule, you can prohibit switching on the phone by manually selecting one specific standard, but this is associated with additional inconveniences. For example, choosing a high-quality working GSM (2G), you deprive yourself of 3G Internet, and vice versa, choosing an unstable 3G, you run the risk of interruptions in calls.

Installation of the amplification system allows you to solve all these problems at once and ensures reliable operation of both voice communication and 3G-Internet.

Ways to Enhance 3G Signal

Different approaches are used depending on whether you want to improve the quality of only 3G Internet or you also need to strengthen voice communication.

When the 3G connection is used only for Internet access, the best solution is to install an external antenna connected to a WiFi router or modem. This is the most economical and simple option that does not require the purchase of expensive amplifiers and is ideal for a summer cottage or a country house.

However, this method has a number of significant limitations. Firstly, the router and modem provide access to the Internet for smartphones, tablets and computers, but do not enhance the voice communication itself. Thus, if your location has problems with voice communication too, installing a router will not solve them in any way.

Secondly, a separate SIM card is required for modems and routers. Using a modem, you can connect one device with a USB port to the mobile Internet, using a router, you can organize a WiFi network to connect several wireless devices. However, a third-party person who comes from the street will not be able to connect from a smartphone to their operator's 3G Internet: you first have to provide him with WiFi access.

When you need to provide access to 3G-Internet directly from mobile devices or improve the quality of voice communication, you cannot avoid installing an amplification system with a repeater and an internal antenna.

We'll take a closer look at both methods below.

Amplification with router / modem and external antenna

To boost 3G internet, all you have to do is install an external antenna and connect it to a compatible router or modem. The antenna is placed at the point of the most reliable signal reception, preferably in line of sight of the base station. For suburban areas, this is a house roof or a special mast. In the city, it is enough to take the antenna out into the street: it can be fixed on a balcony or on the outer wall of a building.

The antenna itself amplifies the signal and transmits it over a wire to a router or modem. Coaxial cables such as or are used to connect devices. Also in our online store you can purchase with soldered connectors. It is desirable that the cable length does not exceed 5-10 meters. Antennas are usually connected to N-type or SMA connectors.

3G routers have a slot for a SIM card and, as a rule, do not differ much from ordinary home routers for wired Internet in configuration. Most 3G routers on the market today support WiFi and allow you to set up a wireless LAN. We recommend our customers a 3G / 4G router, which has established itself as a reliable and inexpensive solution for home and office.

A more budget-friendly option is a set of a regular home router with a USB port and a compatible 3G modem. Setting up the modem after connecting to the router is automatic and does not require user intervention. In the GSM-Repeaters.RU store you can buy kits tested for compatibility, for example,.

If a modem is used, special adapters are added to the circuit -.

Pigtails - adapters for connecting antennas to modems with CRC9 (left) and TS9 (right) connectors

Selecting and installing an external antenna

The cellular signal is vertically polarized, and if the antenna is incorrectly positioned, the quality of the connection will suffer greatly. As a rule, a polarization indicator (usually an arrow) is located on the antenna body, according to which it should be positioned in space. In the absence of an arrow, the name of the antenna can serve as a polarization indicator (the inscription must be readable).

For mounting it is best to use that will simplify further alignment and tuning of the antenna. The antenna itself should be directed towards the base station of the cellular operator. You can find out which operators are working in your location using our website.

You can determine the exact location of the nearest tower by installing the OpenSignal or Netmonitor application on your smartphone. Also, some modems, for example, are able to show the signal level in decibels.

Huawei e3372 web interface allows you to view the current signal level in decibels (dBm)

OpenSignal and Netmonitor applications

OpenSignal and Netmonitor are smartphone apps that allow you to view the current signal strength in decibels (dB) and quickly locate the nearest base station. The data on the towers of mobile operators is updated by the users themselves, so that the database is always up to date. OpenSignal is available for Android and iOS operating systems, Netmonitor for Android only.

Signal strength is measured in decibels: the closer the indicator is to 0, the better the connection. For example, -50 dB means a strong signal, and -110 dB means a very weak signal.

OpenSignal has a friendly interface and automatically shows the direction of a nearby base station using a compass. The Netmonitor application contains more settings and is intended for advanced users. Both OpenSignal and Netmonitor have a mode of displaying base stations on Google Maps.

We recommend using OpenSignal and Netmonitor for signal strength detection and antenna alignment. Knowing the signal strength in decibels and the location of the tower, it is easier and avoids mistakes when installing and configuring it.

Amplification with a repeater

Often, active amplification of the signal is required by means of a special device - a repeater. The fact is that the above-described strengthening of the 3G Internet using a router and an external antenna is convenient, but not universal. In particular, this option is not suitable for people who need to strengthen voice communication, as well as in cases where it is necessary to provide access to a 3G connection to all nearby users. In addition, the antenna gain may not be sufficient for stable operation with a very weak original signal.

In these cases, it is necessary to install an amplification system with a repeater. The principle of operation of such a system is quite simple: an external antenna picks up the signal and transmits it through a cable to a repeater, which amplifies it. The amplified signal is transmitted to an indoor antenna, which propagates it throughout the room. The outgoing stream is amplified in the same way: the signal from the subscriber goes to the internal antenna, amplified by the repeater, transmitted to the external antenna and radiated towards the base station.

The coverage area of \u200b\u200ba repeater directly depends on its power. For home use, in most cases, a 50 mW repeater with a 65 dB gain is sufficient. An excellent solution in terms of price-quality ratio is a repeater from a well-known domestic manufacturer. More powerful devices such as (75 dB, 200 mW) or (80 dB, 500 mW) are used to cover a large house and / or with a weak input signal.

Repeater Baltic Signal BS-3G-65 with a frequency range of 2100 MHz and a gain of 65 dB

Repeaters also differ in the supported frequency bands. To amplify 3G, you just need to purchase an amplifier with support for the 2100 MHz band, but in some cases it makes sense to think about buying a multi-band repeater.

For example, using a repeater with 900 and 2100 MHz frequency bands will simultaneously improve GSM (2G) and 3G, while the dual-band 2100 and 2600 MHz model will provide 3G and 4G support. The most expensive repeaters allow you to simultaneously strengthen all used cellular standards. The consultants of our store will be happy to help you choose the right repeater model for you.

Installation example for Nika-3 ceiling antenna

For all their versatility, repeaters also have several limitations. The main one is due to the fact that the external antenna is directed to the tower of a particular mobile operator, and if the towers of other operators are in the opposite direction, their signal will not be amplified. In such a situation, to amplify the signal of several operators, you will have to install several directional antennas connected to the repeater through a splitter.

The second limitation is related to the "side effects" of analog gain. The radio signal always contains a certain percentage of interference, which is also amplified by the repeater. With a weak signal, the proportion of interference can be significant, which will lead to a noisy broadcast at the output. Strengthening will still occur, but the quality and speed of communication may turn out to be lower than originally predicted.

Conclusion

Let's summarize and briefly talk about the amplification of a 3G signal:

• It is impossible to amplify a signal that does not exist. To amplify any signal, it is required that it be captured by technology.
• The main reasons for a weak cellular signal are remoteness from the base station and various obstacles in the path of the radio wave.
• In Russia, 3G communication in the vast majority of cases operates in the 2100 MHz range. All 3G amplification equipment must support this frequency range.
• You can only strengthen mobile internet or mobile internet along with voice communications. To amplify only the Internet, an external antenna and a 3G router or modem are enough. To also enhance 3G voice communications, you will need a repeater amplification system.
• The external antenna must be directed towards the tower of the cellular operator. To find out the tower location, use the OpenSignal and Netmonitor smartphone apps. When installing the antenna, observe its polarization.
• Antennas are connected to devices using special connectors. To connect to a repeater, an N-type connector is used, to a router - SMA, to modems - CRC9 / TS9. To connect the antenna to the modem, you will also need a special adapter - a pigtail.
• The 3G repeater acts as an amplifier for the signal from the external antenna and transmits the amplified signal to the indoor antenna located in the room.
• Repeaters are single-band and multi-band. A single-band repeater supporting the UMTS-2100 standard is sufficient to enhance 3G communication. Multi-band repeaters allow you to simultaneously strengthen several communication standards and create a foundation for the future (for example, provide support for 4G).

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

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

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

1. Using an antenna.
2. With antenna and amplifiers.
3. With multiple antennas and multiple amplifiers.

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

You need to know exactly in which range the 3G signal of the selected telecom operator is transmitted, and where the boundaries of this signal are. A regular cell phone or spectrum analyzer is suitable for checking the signal strength.

Checking the signal level

Before you strengthen anything, you need to catch something. We determine the range of working frequencies of voice communication and the Internet. The image above illustrates the entire spectrum of the frequencies involved: television signal, wi-fi, DECT, GSM, LTE, etc. It is important to understand in which range the base station at the point being tested is the Internet. It can be transmitted in UMTS 900 and UMST 2100.

In Russia, 3G signal has its own standard: UMTS 900 and UMST 2100.

All smartphones and 3G modems work using both these standards. In cities, due to a small coverage radius, but a higher signal transmission speed and stability of work with a large number of connections, the UMTS 2100 standard is used.

Portable Spectrum Analyzer SPECTRAN HF-6060 V4, with which the antenna direction is determined

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

Search the Internet for how to do this on your phone. Here are the most common codes.

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

If you cannot find the parameters you need, please use another phone. As a result, you need to define the Rx CH parameter. The first value surrounded by a red frame shows in which range the signal is received. If the value is within 10562-10838 it is UMTS 2100, if within 2937-3088 it is UMTS 900. Having determined the operating range, you can accurately select a 3G signal amplifier, for example, high-quality Picocell 900 or Picocell 2000.

The yellow frame shows the 3G signal reception level. Having constantly changing dynamic parameters of the signal level, we are looking for the best reception point. Less is better. Ideally, it is better to place the antenna higher on the roof, but you can find points of reliable reception inside the house.

Equipment selection

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

Directional antenna AP-1900 / 2700-17 for cellular signal amplification

An antenna of the AO-2000-11 brand shows a fantastic result - with a high KU \u003d 11 dB and a circular radiation pattern. It works on the set and forget principle. Its advantage lies in the principle of operation. It can pick up a signal from several base stations at once, which significantly affects the speed of the Internet. No need to look for the direction of the signal.

Omnidirectional antenna, model AO-2000-11 for 3G signal amplification

In almost 80-95% of cases, when the 3G signal is somehow caught, it is enough to screw the 3G repeater TAU-2000 from Picocell to the antenna, and you will catch a stable 3G / 4G signal.

To prevent signal loss between the antenna and the amplifier, I recommend using a cable with a large cross-section, the lugs of which are commercially crimped or with a special tool.

Ready-made kits

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

Kits can be of several types:

• without amplifier;
• with an amplifier;

Connection diagram of equipment for amplifying 3G signal throughout the house

Consider kits without amplifiers. These kits include an antenna and a wire. Conveniently, if you have a modem or router, then the cost of strengthening the 3G / 4G signal will be minimal. A set of wires and an antenna will cost you from 5000 rubles.

Antennas are selected based on the terrain, the number and distance to base stations. This set can always be increased with an amplifier, the final price of the equipment will rise, as will the quality of the received signal.

Any antenna can be used, including those given when selecting equipment, but it is better to buy a modem Huawei E392, although its price starts from 3200 rubles.

Watch a short video of everything described in the article, if anyone is interested in the subtleties, go to the site indicated in the video clip.

And finally, I will share my observation: buy an antenna and equipment in specialized stores, and not in cell phone stores, what they sell there does not work.

The Connect antenna is made for the beauty of the interior. The usefulness of this device is questionable. Can only be used as an extension cable for a modem

Ask questions if something is not clear. Good luck with your shopping.

How to choose the right internet amplifier for a summer residence - TOP-7 best devices [Rating]

With the help of an Internet amplifier, you can significantly improve the signal quality in the country, at home and in any other room.

Effective devices have been on the market for a long time.

These are the so-called extenders or extenders.

Their main task is to expand the existing signal.

In rural areas or in a place where there is very weak network coverage, it makes no sense to use an extender, since the poor quality of the Internet in this case does not depend on the router, but on the poor network of the operator.

Perhaps there are not enough towers on the territory, the connected ones have a low bandwidth, or buildings, forests and so on "interfere" with the signal.

To solve the problem of poor internet in a private house, we recommend using repeaters Are special gadgets that can increase the speed of the Internet several times by reducing the signal-to-noise ratio.

You can improve the quality of the network using special kits for strengthening the 3G-4G signal.

Content:

When choosing an amplifier kit, you should pay attention to the following parameters:

• Coefficient signal amplification. It is customary to consider the values \u200b\u200bof the indicator, which are 8 dB and above - the normal level of amplification. Such repeaters are perfect for use in areas remote from the city;
• Frequency range - this is a kind of reproducible band. The larger it is, the more efficient the repeater will work;
• Mount type. In order for the amplifier to catch the already existing signal from the tower, it is necessary to install its antenna as high as possible. Typically, users choose to install the roof of the house. When buying a product, first decide on the type of fastening, and then select the options that are suitable for yourself;
• Kit cable length ... Determined by the peculiarities of the location of all devices in the set;
• output power (from device to base station).

Also, you should pay attention to the temperature range at which the device will work in normal mode.

If you live in a region characterized by frequent frosts, this indicator will be almost the main one when choosing a gadget.

When choosing an amplifier, consider your location, the approximate distance from the nearest tower to the house, the required number of connection points. Remember that the total baud rate achieved by the amplifier will be shared among all.

Estimated cost: 5 500 rubles.

REMO is the name of the Saratov enterprise for the development and production of electrical and radio devices.

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

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

INTERESTING. The first attempt to make mobile telephony was made by the New York police in 1921. A little over ten years 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 through 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.

Strengthening the cellular signal is technically feasible and cheaper in money. We buy an antenna, install and use the benefits of civilization 🙂 But! You need to choose the right amplifier. And setting up the equipment is not so easy. 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 specialists means paying money.

Internet booster. Dreams and reality

Let's start with the definition of needs. How much traffic is enough per month? What speed do you need? Viewing vidyushek, surfing by itself, possibly downloading torrents, well, network games. If we start counting from the friezes, then the speed is needed within 5-15 megabits. More is better. The channel at the level of 2-3 megabits is enough, but you can forget about downloading.

You can sit and count traffic. On average, it turns out in the region of 15 gigs. On average, this is between needs. Some people watch films more often, others download more, and still others play. So you need to choose a tariff with more daytime traffic and nighttime 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 the following material is of interest to those who decide to strengthen the reception of cellular communications. Yes, yes, we won't 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, there is a village.

IMPORTANT! The main reason for using satellite Internet is the impossibility of providing the service in another way. Most often, the equipment is installed at the "last mile", that is, directly at the customer. The main feature of 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 cell phone.

First, let's look at the coverage maps on the operators' sites. But, we do not trust them strongly - they are for those who will definitely not get a connection нули Have you estimated your location? Now we open maps from Google or Yandex. We define the house precisely. It remains to match the location with the coverage areas. Perhaps the settlement will be covered by several 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 of finding the desired cell are discussed. What for? “Air” differs from the cable in that any unevenness of the terrain affects both the signal level and the speed of the Internet. You can walk around the neighborhood with a beech or tablet, entering the 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 a modem, and that to a computer. We launch the program "MDMA" and turn the device on the roof. We do this slowly, constantly fixing the signal level. Unaccustomed, 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 one. Here we will direct the antenna to him. If you are thinking about buying an amplifier, take a look at the performance characteristics. It may turn out that the increase will not justify the money spent.

INFORMATION. Repeaters are cellular signal repeaters and amplifiers. Devices are used to expand coverage areas. In general, this is an actively working radar equipment that functions 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. For simplicity, you can use the services "Ubnt" or "Linktest". Let's say right away, do not take this data on faith. According to calculations, it turns out that a height of 20 meters is needed, but really high-quality reception is at 7-8 meters. Another tip is not to try to get speed like in the city. The maximum for summer residents is 20-30, sometimes 40 megabits.

And the last in this section. Doing the right thing 🙂 calculations, long choice of antenna, actually manual soldering, height 15 meters, get 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 approximate orientation, get a signal gain of 70-80 percent. The result is good, there is less money and less effort.

Antennas to enhance the Internet signal

In an amicable way, amplifying equipment should be selected simultaneously with the search for a reliable signal. It is better to immediately pick up a set of antenna, mast, bracket, cables and other gadgets. This is the only way to understand what effect actions will have. And these are not all 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 from the operator, it's easier to split partisans during interrogation 🙂

Now about the form. It is not necessary to order any special model from the other side of the planet. Do you sell panel antennas nearby? Here you go. 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 helps a lot to switch between 3 and 4 G. Why? 🙂 It's better to surf on a four - the browser just flies, but to download large volumes - 3G is beyond competition.

Calculation of the antenna for strengthening the cellular signal

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

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

DID YOU KNOW ... how cell base stations are built? The first section is set 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 trunk. Then they improve the territory - they erect a fence, install drainage systems. Only after that, the installation of the BS begins - the installation of sector and radio relay antennas, and other devices. Then electricity is supplied, lightning protection, light barriers and grounding are installed.

Let's not powder our brains with evidence and calculations that determine the choice of configuration. Disputes on this topic have ended even on specialized forums. It has been proven that in case of uncertain reception, narrow-beam MIMO is the best option. Among the positive aspects, a good increase in speed and connection quality. The only drawback is that you need a modem with two antenna connectors.

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

That's what shouldn't be too much trouble with the 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" all operators yourself.

We do not discuss self-crimping of the cable. We need relevant knowledge and skills. And for those who are in the know, advice is not required. But even with a ready-made kit, difficulties may arise. You can calculate the loss and select the correct cable. But the price is unlikely to please. So there are only a couple of options left. Loss can be avoided by using a short coaxial cable.

After all, it is enough to bring the cottage to the second floor or to the attic. And here we mount a router with a modem. Further, as you wish, 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 problems with losses.

We calculate the length and pull the cable to the router. Those who wish can suffer - make the cable themselves. Business is nothing at all. And you can get by with a piece of twisted pair and adapters. But why? Not that expensive 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 you are unlikely to do this very often.

How to mount a cellular signal amplifier for a summer residence

It's time to comprehend and summarize what was said above. So, we fix the antenna in a place that corresponds to the following parameters:

• Maximum height. Do not become a tightrope walker. Height is high, and safety comes first;
• The smaller the cable, the better;
• Strength. The larger the antenna area, the more likely it will be blown away by a gust of wind.

IMPORTANT! For almost 20 years, scientists have been “breaking spears” in the debate about the dangers of cell phones. Despite the fact that the WHO has classified radio emissions from mobile phones into group 2B - a potential carcinogen - there is no 100 percent data on this score. 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.

Do not take advice literally. The maximum height does not mean the installation of a separate 30-meter mast 🙂 Same with the cable. Introduce an extensible concept into the house, you can stretch it through the whole house. What a reduction in footage here. And so in everything. We advise you to reasonably approach the selection and installation of any equipment. The result should be pleasing and not cause additional problems.

An amplifier of a signal of a mobile Internet for a summer residence. Lightning protection

It seems that they calculated everything, thought about everything. It's time to mount. But no, they forgot about one problem. The higher we raise the antenna, the greater the chance of a lightning strike. Do you know we are building such an excellent lightning conductor 🙂 The situation only seems ridiculous. The reality is that you can quietly build the highest point in the area. Naturally, it's not a fact that you're so unlucky. But why risk it?

We made a 3g amplifier with our own hands, and got burned out electronics throughout the house. No, this is not for us. There are several solutions. You can get confused with full protection. True, this business is VERY decent. It was spent tens of times less on strengthening. Another option is everyday ways:

• Don't raise the antenna too high. Let the signal improve by 80% instead of 100, but the lightning won't strike;
• Planning trips longer than half a day? We take 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 the refrigerator empty 🙂 Those who set the house under security will have problems;
• A thunderstorm has begun - at least pull out the antenna cable;
• Do not try to build lightning protection yourself. The result may be the opposite.

Amplifier of the Internet signal in the country. What's the bottom line?

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

In such a layout, we do not count the ladder, screws, screwdriver and rail 🙂 Real men always have a tool at hand. As a last resort, there are good neighbors, good friends or relatives. So it is quite easy to get a signal improvement from -110 dB to -90. And money is not the most important thing - you need desire, patience and time. Good luck for this!

Now we will discuss with you what amplification of a cellular signal is. We will indicate the main ways that allow you to achieve it. A few words will also be said about the specifics of the third generation networks. But first things first.

How does the cellular signal system work?

The scheme of operation of this type of mobile radio communication, which works on the basis of and consists in creating a high-frequency radio channel of your phone with the operator's station, providing mobile communication in the range from 450 to 2700 megahertz. With the help of this system, calls, text messaging and even access of network users to the Internet are made.

In addition, there are several standards for communication of the cellular network, which are determined by the frequency and method of organizing the radio signal. The standard of mobile radio communication networks GSM, for example, is built in such a way that regardless of the location of your mobile (city, forest or on the move), it is more likely to receive a signal from base stations of radio communication.

"Holes in coverage" or "blind spots"

Why, in this case, is the strengthening of the cellular signal required? The reason is simple - there are obstacles in the signal path, like multi-storey buildings, wooded areas and other obstacles that reflect the radio signal. Often it is because of this that you cannot use your mobile services, and the GSM signal disappears.

As a result, it turns out that the maximum allowable distance for reception by a GSM-900 phone, which will allow using the signal of a mobile operator, is seven kilometers within the city and less than thirty-five kilometers from it. For the 3G standard, it is half that. The CDMA standard, in turn, has twice the coverage distance than the GSM standard, from one.When the radio signal strength becomes insufficient, so-called dead zones are formed, where the GSM signal strength is minimal, which affects communication (communication is interrupted at times or completely disappears).

There are such places in every city and outside it: interiors in residential or office buildings, underground premises (basements, underground parking lots, ground floors, etc.), warehouse and industrial buildings, high-rise buildings (more than 10 floors high), huge commercial and entertainment centers, settlements and houses outside the city limits (which are far enough from base stations of communication). The reasons for the appearance of such dead zones are also quite varied: thick walls of buildings, a large number of metal and reinforced concrete structures (which represent a strong obstacle to the radio signal), premises at a certain depth (the signal may simply not break through), high altitude (usually above 30-35 meters the network disappears or, in other words, there is an interference effect) or remoteness from the signal source of the cellular network. It is at such moments that you will need to strengthen the GSM signal of the cellular connection.

How to deal with weak signal problem?

To eliminate this problem, you need a signal amplifier between the carrier's base radio tower and the room that is not receiving the signal. This cellular signal amplification tool relies on an interconnected system of equipment: donor and serving antennas to receive and transmit signals between your carrier and your mobile phone, power splitters and cables.

How to strengthen the cellular signal with your own hands?

Work on amplifying the signal should take place gradually, in several steps, to achieve maximum effect. To do this, you need to determine where your amplifier antenna will be located, and find out its power. The easiest way to do this is with your own mobile device, which indicates the level of signal reception (often in the upper right corner of the screen). The places where signal reception is usually better are on the roof of the house or outside the window of your high-rise building (in an urban environment). Having determined the place where it picks up the signal best, you can proceed to fixing the external antenna.

The next step is to place the amplifier. Everything is simple here - you need a free surface and a close location of a 220 volt outlet.

The last step will be the placement of the internal communication antennas. The principle of their placement is the possible permissible distance from the external antenna, as this will provide the most effective amplification of the cellular signal.

The final stage will be commissioning - connecting the antennas to the amplifier. Once you have installed the cable, crimp the ends with N-type connectors and connect. You can start the system.

A note on 3G networks

Strengthening the signal of 3G cellular communication occurs in almost the same way, but with one important detail: outdoors, the intensity and continuity of the 3G signal is several times higher than indoors. In this case, the signal is impeded by wall ceilings and a proper positioning of the internal antenna in the room is required.
