Amplifier of reception of a signal of cellular communication megaphone. Cellular signal amplifier "Megafon. Cellular communication Megaphone. Operating frequency

In houses and apartments where there is no possibility of connecting wired Internet via a fiber optic line, there is an option to use wireless access via a USB modem. Such devices are available from popular mobile operators. Megaphone is no exception. Unfortunately, sometimes a weak signal level does not allow you to enjoy the Internet, so you need to figure out how to fix the situation.

A 3G USB modem is a small device in the form of a flash drive. Ease of use lies in the fact that after the purchase you do not need to configure anything. It is enough to connect the modem to the PC, and the operating system will configure the program itself.

Subscribers can purchase new models of USB modems, the main feature of which is a high data transfer rate:

• E173 - 7.2 Mbit;
• E1820 (E352) - 14.4 Mbps;
• E367 - 28.8 Mbps.

The outgoing speed of all types of devices is up to 5.76 Mbps.

The above throughput is theoretical. Often, when using the gadget, malfunctions occur. Low data transfer rate is the scourge of the provider and the subscriber. Solving this problem by the operator (building a new base station or changing settings) is problematic.

Reconfiguring sectors leads to the fact that the coverage and signal level at the client's address will become better, but at the same time it will worsen in another part of the settlement. Instead of one problem, the operator can get several. The subscriber has to fix the failures on his own.

What does speed depend on?

The following factors affect the data transfer rate:

• Computer performance - on the box with the modem, the characteristics and requirements for the PC must be indicated. If the specifications do not match, the device may not work or function incorrectly;
• Weather conditions: rain, snow, fog, even blossoming leaves on trees, can interfere with the radio signal and lead to a decrease in speed;
• Distance - the farther the base station is located, the worse the coverage and the level of the cellular signal;
• Network congestion by time of day - there are several daily peaks when the BS is overloaded. The number of channels does not change, but the number of users logged into the network varies constantly. The more people connected at the same time, the lower the data rate. This is well manifested in resort cities - in winter and autumn, mobile Internet works excellently for local users, but with the onset of the tourist period, problems arise with access to the network;
• The presence of construction sites, cranes, building sheathing of metal structures - all elements can affect the radio signal, taking it upon themselves. As a result, if a new house is being built nearby and a crane is brought in, there is a drop in speed and signal deterioration in the district.

Everything on which the propagation of radio waves depends affects the data transfer rate.

How to amplify the signal of a 3g modem on a megaphone?

If the bandwidth at your address has dropped, and this happens all the time, then you can solve this problem with:

• hardware;
• Antennas;
• Homemade amplifiers.

Before using one of the methods, it is necessary to analyze the situation in order to determine what is most suitable.

Signal enhancement hardware

Hardware includes various signal amplifiers, repeaters, repeaters. These are devices that are installed in the house, connect to a power source (socket). The repeater acts as a transceiver from the BS to the subscriber. A repeater is an amplifier that receives a signal from a BS, improves its quality and transmits it further to the end user's terminal equipment. They do not require any settings. Their main function is to increase the signal level in the room. When using this equipment, the speed can reach maximum values.

A significant drawback is the high cost. You can buy them in specialized stores. The operator also sells some models.

Antennas

Directional antennas also help to amplify the signal of a 3G modem. They can be installed both indoors and outdoors. The design has the same functionality as amplifiers - it "attracts" the signal and redirects it to the modem. Antennas are somewhat cheaper than repeaters and repeaters, but they are less efficient.

Do-it-yourself signal amplification

The cheapest and easiest way to boost your signal is to find a good location for your modem. Surely you know in which direction the operator's base station is located. Try to place the modem in the opening of the window that is directed to the BS. If this measure does not help, then the operator advises using an extension cord. This is a long cable that connects to a computer or laptop on one side, and connects to a router on the other side. Using this cable, you can place the modem in the room as close as possible to the ceiling and to the window. Also, the cable can be taken out of the room. The device must be protected from moisture by wrapping it in a bag or cutting an opening in a plastic container.

Users share their lives: you can attach something spherical to the modem - many use lamps to warm their ears, stainless steel plates or even colanders. The modem is located in the middle. The whole structure is placed in the window opening. The principle of operation is similar to a satellite dish. In this case, the nearest BS acts as a satellite.

How to strengthen the signal of a 4G modem on a MegaFon?

MegaFon 4G Modem is a device for wireless Internet access in the LTE/UMTS/GSM network. The great advantage of the router lies in its versatility - it can work in both LTE and 3G, as well as 2G.

The device does not require additional settings. The first time you connect, the computer's OS will install itself.

Peculiarities

Routers focused on working in a 4G network have some features:

• Connector for memory cards Micro SD Card Slot (recommended capacity - up to 32 GB) - the card is not supplied.
• Online update of the program to the modem (if you are in your home region, traffic is not paid);
• There is a connector for connecting an external antenna (MIMO technology) - CRC9 (it is not included in the kit).

Strengthening the signal on a 4G modem is no different from the principles for improving third-generation routers. For amplification, repeaters, repeaters, including handicraft ones, are used. The only thing is that these devices must support the 4G format. Devices that boost the 3G signal may not have any effect on the LTE modem.

When buying an amplifier device, be sure to check with the seller the formats that it supports.

DIY signal amplifier

Making a 4G signal booster at home is quite simple. To do this, you need a single-core copper wire, 10-12 m of coaxial cable, fasteners and plastic.

A "figure eight" is being prepared from the wire. Such a device is called the Kharchenko antenna. In the center, the structure has a joint. A cable is soldered to this connection. The other end will wrap several turns around the modem itself. A metal plate can be attached to the antenna, which will act as a reflector. Also, the edges of the rhombus are sometimes wrapped in foil. The antenna is placed on the roof or pole.

Femtocell

Of all the possible repeaters, repeaters and amplifiers, the best option is the femtocell. This unit is a small base station. Radiation standards do not have any impact on human health, but the quality of communication when used becomes ideal. Devices are installed in areas with poor coverage, in basements, at remote sites.

The problem is that femtocells are not sold to individuals. And if you buy it, then there will be little sense from it. The operator prescribes the parameters of the station on the BS. If this is not done, then it will not work. Devices are issued to corporate clients after radio frequency research. The femta requires a fixed Internet connection with a speed of 5 Mbps.

Using a miniature station at home is not cost-effective.

This article will consider a fairly detailed overview of products on the market for providing 3G / 4G Internet to the private sector - cottages, country houses, cottages. The article has been updated for 2020.

Types of Internet signal amplifiers:

1. Antenna with built-in 2G/3G/4G modem (MTS, Beeline, Megafon, TELE2, Yota):

In the year 2011-2012, when the development of 3G wireless Internet began, antennas with a built-in modem appeared on the market. Now the price is approximately 6-10 thousand rubles with a modem.

Pros:

1. there are no losses on the coaxial cable that affect the speed of the Internet,
2. flexible cable,
3. the price is quite low.
4. Fast Internet if the antenna is of good quality.

Minuses:

1. Unstable operation of the modem at lengths of more than 5 meters! You have to be prepared that 1-3 times a day you will have to distort the power at the router. And if the router is on the second floor or attic, then this causes only certain emotions :)))
   Just because of this problem, the next generation of antennas with a built-in modem and router appeared, which will be discussed in the next section.
2. The seller can slip an old 3G modem. The older the model, the slower the Internet will work. When buying, this point is highly recommended to check.

2. Antenna with built-in router and modem (MTS, Beeline, Megafon, TELE2, Yota):

As for the Moscow region, when you go to Mitinsky or other radio markets, you will be offered a miracle of antennas to enhance mobile communications in your country house (2 options):

Pros:

1. Antenna cable can be up to 80 meters long! In some cases, this is very convenient! Power and signal are supplied via a single cable. PoE technology.

2. Connectors at the ends of the RG-45 cable (the most popular Internet connector). As a rule, many have a crimping tool. That is, you can not drill a wall or window frame with a large drill diameter to fit the connector, but make a small, neat hole for a thin cable.

Minuses:

1. Such devices do not last long. Because the operating temperature of routers and modem is approximately 0 - 40 C.

Many sellers claim that everything is airtight and the router heats itself. And it really does work in the winter. BUT the worst thing is a cold start, this is when electricity is cut off at -20 C in winter, the router cools down, and then power is supplied and a breakdown occurs. Regarding the upper temperature limit of +40 C - in the summer in the sun in a closed space with a router heating up from work, the temperature reaches more than 60 C.

Both photos are precisely already non-working antennas, which we eventually replaced.

3. Internet signal amplifier CONNECT 2.0, 3.0, etc.

A separate article has been written for this product.

Real cell phone signal boosters look like this...

4. Antenna connected to router/modem

It is also a fairly popular option when the router and modem are indoors, and the antenna is placed outside. The cost of such kits is from 2,000 - 3,000 rubles.

Top selling

14dB MIMO Antenna, Bracket, 10m 3DFB Cable Assembly x 2, Adapter x 2

Top selling

Antenna 11 dB, Bracket, Cable assembly 10m 3DFB, Adapter

Pros:

1. Maximum reliability. Outdoors, only a passive antenna is used, which will not be affected by various weather conditions.
2. Fast Internet with correct installation. The result of testing just such a kit in this article will be shown below.

Minuses:

1. Limited cable length. Recommended up to 12 meters if the cable is 8D-FB. If the cable is thinner, then the speed loss will be more noticeable. With each additional meter, the speed drops slightly.
2. Installation inconvenience. Prefabricated cable assemblies use an N-type connector and its diameter is 20 mm, which makes it difficult to lay the cable inside the room. The solution is to make 1 connector yourself using a special tool or a soldering iron. Connectors are also smaller in diameter, but they are usually used only for a thinner cable.
3. Use of a thick cable. 8D-FB cable has a cross section of 11.1 mm and you cannot hide such a cable in a plinth.

5. Antenna with built-in 2G / 3G / 4G (Lte) factory-made router

4G Lte outdoor router with built-in antenna. The price is approximately 9-12 thousand. You can see the characteristics.

Top selling

3G/4G outdoor router

Pros:

1. Cable length up to 80 meters! Signal and power are supplied over a single cable using POE technology.
2. Flexible cable.
3. Maximum internet speed. Supports MIMO technology. No other kit will give you higher speed.
4. The antenna supports absolutely all frequencies from 700 to 2700 MHz and all 2G, 3G and 4G standards.
5. Stability of work at any temperatures from -30 to +50 degrees. Factory quality, not basement production from the Mitinsky market :)

Minuses:

1. 1. It is inconvenient to change the SIM card. Strictly speaking, it is not a fact that you will ever need to do this.
2. 2. Not revealed yet :) Perhaps the price will not seem the cheapest.

Recently there was an overview video of such a device:

Common misconceptions when choosing Internet amplifiers

1. 4G/LTE not only works on 2600MHz (2500-2700MHz), but also LTE800 and LTE1800.

At the same time, only LTE800 and LTE1800 practically work outside the city! And many sellers sell a 2600 MHz antenna, which is relevant only within the city.

2. "The greater the gain of the antenna, the better" But no!

The higher the gain, the narrower the antenna pattern and the more difficult it is to accurately point the antenna at the operator's base station! It is rare that someone directs a high gain antenna correctly during installation. According to statistics, 8 out of 10 buyers who have installed such an antenna on their own, do not direct it correctly. After all, it is enough to deflect the direction of the antenna by 2-3 degrees and the gain will not be 27 dB, but the same 3-5 dB. And do not forget that the speed of the Internet does not depend on the signal level, but on its signal-to-noise ratio!

An example of an antenna pattern with a gain of 16 dB (on the left - in the vertical plane, on the right - in the horizontal):

An example antenna pattern with a gain of 27 dB:

In the vast majority of cases, an antenna with a gain of 11-17 dB is enough! And how to put it correctly - will be discussed below.

3. I have not seen antennas with a real coefficient of more than 18 dB on the market.

We tested in practice any antenna 20-28 dB and they all amplified the signal by no more than 18 dB, some even less than 14 dB! Many unscrupulous artisanal manufacturers take advantage of the fact that no one can verify the true characteristics of antennas.

4. Active 4G signal amplifier (repeater)

There are similar offers on the sites:

And if you still have the task of choosing and buying a repeater, then you can read.

An example of installing a GSM, 3G, 4G amplification system

How to install the antenna correctly

Now let's discuss one of the most important questions - how to properly install the antenna.

The scheme is this:

The main point is that the higher we raise the antenna, the higher the Internet speed will be, and it’s not even about the signal level, but about its quality, which is scientifically called signal to noise ratio and in many programs and phones is designated EcIo. The less the signal encounters obstacles from the tower of the mobile operator to our receiving antenna in the form of neighboring buildings and forests, the better the signal will be and, accordingly, the speed will be higher.

I usually give this example: they hung the antenna from the window - they got a speed of 5 Mbps, hung it on the roof - 10 Mbps, and hung it on the roof and also raised it to the mast - 20 Mbps. In this case, you can put an antenna on the roof with a gain of 8 dB and get a speed higher than that of a neighbor with a 20 dB antenna outside the window.

This is how the cheaters put it:

And this is correct:

And we get this result:

88 Mbit / s - to be honest, this was a record :) We used a set of equipment with a coaxial cable and a router indoors.

Alternative to 3G/4G Internet

wifi bridge

If there are residential apartment buildings on the horizon with a radius of up to 10 km, then with a local provider that connects apartments, you can negotiate a WiFi bridge between the residential complex and your house. 2 antennas are placed towards each other, one on your house, the other on the roof of an apartment building.

In practice, such a connection costs 12 thousand and a tariff of approximately 1000-1500 rubles for 15-30 Mbps. But this is really unlimited Internet, which, unlike 3G / 4G, does not sag in the evening when the load on the network increases. And a good ping up to 8 ms - for those who like to play tanks and other modern games, this is a luxury in the country :)

WiMax

Wimax is a 4th generation connection. In Russia, this communication standard has not been widely used for a number of reasons.

Some small local companies negotiate with telecom operators to lease their communication channel and place their Wimax equipment on towers.

The Internet speed of 10-50 Mbps depends on the remoteness of the tower and the correct installation of the antenna at the subscriber's house. Ping about 40ms. The channel is symmetrical. The cost is about 1000-1500 rubles per month.

conclusions

1. 1. It is worth trying to start by looking for alternative options for connecting to the Internet.
2. 2. Don't buy the first antenna you see on the market. Antennas with a built-in router and modem are short-lived. Check the frequency range of the antenna, 4G / LTE works in our country at frequencies of 800, 1800 and 2700 MHz. At the same time, in my opinion, 1800 MHz will be the main speed range outside the city, and 800 MHz will be used in very remote corners, but the speed in it will not be very high due to the narrow spectrum. And the 2700 MHz range is mainly in cities or near densely populated areas.
3. 3. In kits with a coaxial cable, do not save on the cable itself, it is better to take a thicker one and pay a little extra. Some vendors offer TV cable. Yes, it is cheaper, but it has a different wave resistance! You need 50 ohms, not 75, like a television cable.
4. 4. The antenna must be placed high if you do not see the cell tower from the window! This moment affects the speed of the Internet more than the quality of the equipment itself!

The best 3G / 4G Internet signal booster is a passive antenna with a minimum length of coaxial cable or an external router! And if there is active subscriber equipment (modem, router) inside, then it must fully comply with the climatic conditions of operation!

The need to use the device often arises even in large cities with a large number of transmitting and receiving antennas. In particular, dense buildings can interfere with the normal connection, problems are also observed in the semi-basement, basement and basement rooms.

Cellular signal amplifier "Megafon" is required:

• at low speed and weak bandwidth of the Internet channel;
• frequent receipt of messages about uncalled subscribers;
• regular and unreasonable disconnections;
• impossibility of passing incoming/outgoing calls;
• regular occurrence of interference in the process of communication.

Signal amplifiers "Megafon" are often used in country houses, villages and cottages, in recreation areas and other places that are far from the base station.

In addition, the presence of these devices is relevant in hilly and wooded regions, as well as in areas that are located in lowlands or have other natural interference.

The network of the "green" operator, like any other, is distributed unevenly. Somewhere devices catch the Internet better, somewhere worse - and then the question arises of how and how to strengthen the signal of the MegaFon modem. You can buy devices specially designed for this purpose, but this is too simple and expensive. It is much cheaper to build an antenna from improvised means, especially since special knowledge and skills are not required for this.

Signal booster for modem Megafon

Compact modems of operators, although they allow you to stay in touch away from your home Internet, sometimes give out a low connection speed or refuse to see the network at all. A variety of factors influence this:

• distance to the nearest cell tower - the farther it is, the worse the signal will be;
• the density of the surrounding buildings and the number of walls separating from the street - part of the radio waves are absorbed when passing inside the building or through obstacles. That is why we see a weak signal in basements, subways and large shopping centers;
• natural phenomena - precipitation and even foliage on trees affect communications;
• time of day - Internet speed drops if a large number of users access the network at the same time. This can be observed at lunchtime, when people are distracted from worries, or in the evening, when they come home from work;
• computer specifications. If they do not meet the requirements described in the modem documentation, you can not hope for a stable Internet;
• standard settings. In the "Default" mode, the modem switches to 2G already with 2-3 "sticks" of the antenna. With a hint of a bad connection, it is impossible to work at full speed. To opt out of switching to 2G, go into the modem program, find "Network Search Mode" in the "Connection" tab and select an item with a name like "Always 3G".

Before you despair and try to strengthen the 3G signal of the MegaFon modem at home with your own hands, check if any of the above is interfering with the device. Change the conditions: from the middle of the room, move closer to the window, go outside, or point the router towards the tower. If simple actions do not help, stock up on tools, materials and start assembling the antenna.

With audio speakers

The easiest way to make an amplifier for a MegaFon modem is to take regular speakers. Connect them to a network or computer, put them next to the device and watch. According to user reviews, the signal in the presence of sound speakers improves by 10-20%.

Just keep in mind that when the equipment approaches, an annoying hum is heard in the speakers. If you are going to try the method, reduce the volume to a minimum in advance.

From copper wire

In this option, you will have to make a little more effort. But the time spent pays off in full: the Internet signal can be improved by 90-95%. To create an impromptu amplifier you will need:

1. 3-6 meters of copper wire;
2. any canned food or drink in a can;
3. can-opener.

First, open a can of canned food. Cut off the top cover completely to make it look like a glass. Eat or give the contents to the household, and rinse and dry the container.

Remove the protective cover from the router. Wrap one end of the wire tightly around the SIM card. Wrap the other around the tin can. Hang the last part through the window on the street and direct the impromptu glass to the tower. Insert the modem into the computer and try to connect.

The video shows a more complex, but powerful homemade antenna. The author gives detailed manufacturing instructions and assembles the structure on camera for clarity.

USB extension cable

If there is no copper wire at hand, use a modem amplifier authorized by MegaFon in the form of a USB cable. Buy a cord of the right length. Plug one end into the computer, insert the router into the other. Position the last part so that the signal improves - send it outside the window or fix it under the ceiling.

To protect the modem from snow and rain, people make special holders from improvised means. Suitable for this is the same tin container or plastic bottle.

• The tin must be removed from the top lid, washed and dried. Closer to the bottom, cut a vertical rectangular hole to fit the end of the USB extension cable that comes into contact with the modem. Insert the cable, connect the router - it should be located inside the jar. Fill the edges of the hole with glue from a gun or cover with electrical tape so that water does not get inside. Cover the open top with cling film.
• For the second option, take a plastic bottle, 3-4 unnecessary CDs, 2 old plastic cards, Sekunda glue, a clerical knife, sandpaper, and hot glue. Cut off about a third of the bottle from the side of the neck. Fold the disks with chamomile, treat the overlapping points with sandpaper for better grip and glue them with “Second”.

Take one card, put the router on it and mark the outline of the device. Bend the long sides of the credit card along the marks to make it look like a scoop. At the second card, on one of the short sides, bend the centimeter - this will be the fastening of the future holder. Glue the blanks with the reverse sides. For the holder, attach to the middle of the "chamomile" of the disks.

To even out the edges of the bottle, melt them with a hot knife. Put the modem on the holder, pull the cable through the neck of the bottle, connect to the device. Glue the edges of the container to the disks with hot glue - a plastic cap will protect the router from rain. After that, all that remains is to attach the makeshift antenna to the window, insert the other end of the extension cord into the computer and connect to the Internet.

Using a repeater

If it is not possible to make an amplifier with your own hands, a ready-made repeater can save. The device is a special antenna that improves the quality of signal reception from the base station. You do not need to configure the repeater - just plug it into the outlet, connect it to the modem and work.

The speed of the Internet with a repeater increases almost always. Exceptions are only those cases when communication services are not provided due to the lack of coverage of the operator in the selected area.

Such devices are sold on Chinese websites, in the official stores of the operator and network outlets specializing in technology. They cost, depending on the characteristics, from 500 to 1500 rubles. On https://shop.megafon.ru you can find popular REMO "Connect 2.0" and REMO LTE MIMO INDOOR. For 650 and 999 rubles, respectively, according to customer reviews, in suitable conditions, they increase the speed by 5 times.

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 there are a large number of mobile operators, there should not be “dead zones” for the Internet according to prior. In reality, everything is different: a person, moving around the area, periodically gets into them. This is due to architecture, the building material from which 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 a wi-fi network. 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. With an integrated approach to 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 types of 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.
