Is it possible to amplify the signal of a USB modem from Megafon? How to strengthen the signal reception of a 4g modem

This article is about 3G and LTE antennas for modems. You will learn how to amplify the signal, and whether it is worth making an antenna with your own hands.

The advantage of 4G Internet over 3G is manifested not only in connection speed. The new generation Internet also benefits from lower ping. So, online fighters connected to MegaFon 4G can feel the qualitative difference between generations even at the same speed. A 4G connection can save the participants in multiplayer battles from lags and increase fps by an order of magnitude.

Unfortunately, enjoying the quality of high-speed Internet is not always possible and not for everyone. Even buying a modem with high-speed 4G from MegaFon is not a guarantee that your mobile Internet will grow wings.
But do not rush to blame the operator for all mortal sins. In some cases, he is simply powerless. This must be recognized, because what is, is: modern technologies are still far from ideal.

A serious interference between the signal receiver and MegaFon's LTE network, in addition to the banal user network congestion, can be:

• a long distance to the base station (the availability of 3G and 4G networks is still an urgent issue for owners of summer cottages and residents of the suburbs);
• potential location of the modem (height, number of storeys of the building, wall material and thickness);
• other interference that gets in the way of the signal: forest plantations, nearby high-rise buildings and structures, power lines.

All this affects the signal quality from 3G/LTE networks not in the best way. Is there nothing that can be done about this mess? It is possible and necessary.

Signal amplifiers - 4G antennas and reflectors - are designed to solve most of the above problems. The 4G antenna for the modem is a powerful directional signal amplifier that looks like its television counterpart. This device helps to seriously amplify the signal strength received by your device.

Antenna handmade: is it appropriate to "assault"?

Naturally, the question comes to mind for many users: is it possible to make a similar design for the MegaFon modem on their own.

It is understandable, for those who want to practice applied radio engineering - making a modem amplifier with their own hands is a great chance to improve skills, learn the intricacies of selecting elements and learn new things. Of course, when making an LTE antenna with your own hands, there is a risk of not only wasted money, but also a burnt modem.

Nevertheless, many owners of 4G modems successfully use a home-made signal amplifier in their apartments and cottages. The Internet has collected many manuals and diagrams for assembling an external LTE amplifier with your own hands. For those who are focused on obtaining a quality result, the best option would be to purchase branded directional antennas.

The indoor version of the antenna that works with the 3G and LTE MegaFon signal is reflective-collective forms. In fact, these are not even antennas, in the full sense of the word. Reflectors (or reflectors) are not attached to the antenna output of the 3G modem. At the same time, the shape of metal reflectors, unlike antennas, is not at all fundamental, and can be arbitrary.

As mentioned above, a feature of these devices is the exceptional roominess of their use. It is not recommended to take them outside the premises, since factory, and even more so, home-made designs are not able to protect the modem from moisture and temperatures.

You should not consider a simple metal reflector as a panacea for serious problems with MegaFon's 3G or LTE signal. Its efficiency is about ten times less than that of a remote 3G antenna. However, such a design is quite capable of adding some missing stability to the modem.

Not a true 4G standard. 4G has been adopted more as a marketing term. In theory, LTE is capable of 100 Mbps downlink and 50 Mbps uplink. That is, 12.5 MB / s "real" download speed and 6.25 MB / s for downloads.

The theoretical peak only occurs when LTE uses the 20 MHz channel to transmit information, which means that one user must be quite close to the transmitting station and that there must be a limited number of users nearby - which, again, is only in theory.

There are a number of things you can do to improve network bandwidth and 4G compatible/modems. It is worth considering that only some of the methods will work for you, depending on the network.

3G/4G Speed ​​Optimizer app

There are several applications that claim to optimize network performance, including Speed ​​Optimizer. Available for Android devices.

The optimizer has a fairly simple algorithm that allows the user to change the maximum download and download speed, limiting one in favor of the other. In addition, it allows you to change the GPRS class, make a choice in favor of speed or stability. The Pro version of the application comes with the ability to scan, change TCP buffer and RIL policy.

Working with 3G and 4G, the application has the disadvantage of battery consumption.

• no interference- remote location from mobile phones, modems and other electronic devices. The presence of household appliances such as televisions, radios, and especially microwave ovens can cause speed drops.
• Maximizing the modem signal- 4G stations use waves to transmit traffic to the modem, so in order to ensure that a large number of these waves reach the terminal, it is necessary to place the modem near a window. Avoid placing the device behind various obstacles, such as concrete and metal walls, and especially trees (water inside the leaves contributes to signal loss).
• Change of position- By changing the direction of the modem antenna, you can improve the signal.

Signal amplification

It is best to use amplifiers for home or office use if you want to achieve good wireless performance. For example, you can increase the speed of 4G inside the house with a signal booster, a pair of compatible antennas. The concept is as follows:

• One antenna is located outside the house, at a sufficient height to pick up a signal greater than the signal of the antenna installed on the mobile phone. This will eliminate the signal attenuation caused by the walls of the house and, depending on the quality of the antenna, will increase the signal significantly.
• Another antenna must be installed inside the house, the signal relay is captured outside the unit.
• An amplifier should be installed between the two antennas, which will increase the signal strength and help avoid cable loss.

Stay on 4G

Whenever the 4G connection becomes unstable and the signal level drops below a certain threshold, the station switches to 3G mode to ensure stability. But there is a trick that will allow the smartphone to connect to the 4G network earlier than usual, and stay in this mode longer.

Note: this procedure works regardless of the operator and does not harm the device, but problems may appear (XDA is to blame). Here's how to do it:

1. Dial ##DATA# and choose edit mode. That's ##3282#, for those rather new.
2. Enter your MSL (here's how to find it).
3. Now choose the WiMAX menu and tweak the following settings, as stated:
   • WiMAX_ENTRY_RX (RSSI) (dBm) – this value defines the minimum signal to connect to a 4G tower, so lowering the default up to -95 or – 100 should make the phone connect faster. If there are stability issues, raise the value back to -89.
   • WiMAX_Exit_CINR(dB) – this value defines the threshold for a phone to drop an active connection. Change the number to 1 and if problems appear, switch it back to 2.
   • WiMAX_Exit_Delay(s) – this number defines the time that CINR must stay activated, before the connection is dropped. So, in order to get by random drops, increase this to 5, or whatever you like. Not too high, we recommend.

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 2019-2020.

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 the Mitinsky or other radio markets, you will be offered the miracle of the antenna (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

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 factory router

4G 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 the point is not even in the signal level, but in 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!

Today we will talk about how to independently make a 4G and 3G signal amplifier and antenna from improvised materials with your own hands at home. We will also consider detailed diagrams and methods for assembling home-made amplifiers and antennas of the 3G and 4G signal.

The development of 3G and 4G networks in recent years has been on a grand scale. And no wonder, because the use of 3G allows mobile operators to significantly improve the quality of their service.

In the absence of wired Internet, you can buy an inexpensive 3G modem and use mobile Internet. But very often the owners of 3G modems complain about the low download speed and ask the same question: "How to increase the speed of the 3G modem?" So, the task is set, and we will solve it!
Reasons for the low speed of the 3G or 4G modem

3G networks operate in the 2GHz frequency range, and for the propagation of radio waves at this frequency, direct visibility to the base station (BS) is needed.

In conditions of dense urban development, the signal can be weakened by hundreds and even thousands of times before it repeatedly bounces off the walls of buildings and reaches your modem. In rural areas, the weakening of the signal, as a rule, is associated with a significant distance from you to the BS of the cellular operator, as well as the presence of dense vegetation in your area, which interferes with the propagation of radio waves.

There are several ways to amplify the signal of a 3G modem, and under different conditions, not all of them will work equally well. It is conditionally possible to allocate software and hardware to solve this problem. In the first case, a 3G modem accelerator program is used. In the second, the modem connection speed is increased by technical means.
Software 3G and 4G accelerators
To the question "3G modem accelerator" Yandex gives an answer of 200 thousand web pages. After reviewing the first ten sites, we see that they all offer to download a miracle program (and for money), which allows you to increase the speed of the Internet modem. Why, then, do cellular operators not include a software package with their 3G modems? Remember the reasons for the low speed of the 3G modem - a weak signal and the workload of the base station. Is the program able to solve these issues - NO!

In particular cases, it is possible to increase the level of the received signal using a USB extension cable. For example, you are in a semi-basement where the signal cannot penetrate, and there is a window nearby. You can try using a USB extension cable to move the modem as close to the window as possible. If you are lucky and the signal quality is much better, you will achieve an increase in speed.

.

By connecting a 3G antenna to the modem, you can significantly increase the speed of your 3G Internet connection. Tip - cable length as short as possible, if not enough, try to use only high-quality RF cable, for example, a 10D-FB cable assembly.

The 3G and 4G signal booster for a cell phone works as follows. A donor external antenna is mounted on the wall of the building or on the roof, which is connected to the amplifier with a high-frequency cable. Try to direct the antenna as accurately as possible to the nearest and less loaded operator's BS. The antenna receives the signal, the repeater amplifies it and transmits it via cable directly to the internal service antenna, which re-radiates the signal to the subscriber.

This system is intended for indoor maintenance of an unlimited number of simultaneously operating 3G phones and modems. Allows you to use the services of all mobile operators MTS, Beeline, Megafon. At the same time, subscribers can move freely within the coverage area.

Now you know the reasons for the low speed of the 3G modem and possible solutions to improve the quality of the 3G signal. Some options may seem controversial to you. But if you really want the space of your premises to be filled with a high-quality 3G signal, then the best solution would be to install a 3G amplifier.

You also need to understand that under the same initial conditions - the signal level and the 3G modem model, all subscribers in different places will have different speeds! The speed of the Internet also depends on the bandwidth of the base station of the mobile operator, i.e. how it is connected: via radio channel or optical fiber. The speed also depends on the number of subscribers. For example, the operator's BS outputs 100 Mbps at the output. At some point in time, 20 people use the Internet and, accordingly, the speed will be 100/20 = 5 Mbps per subscriber. In turn, if 50 subscribers in the district use the Internet, then the speed for each will be no more than 2 Mbps. In most cases, many notice that the speed of 3G Internet begins to slowly fall in the afternoon and the peak of the fall is observed in the evening, when the load of Internet traffic on cellular networks is maximum.

Antenna 3G and 4G how it works

Any antenna is a passive signal amplifier!

Consider the most common case - connecting a 3G modem through an antenna, which is placed on the roof of a country house. Further from this antenna, the signal is conducted through a 50 ohm coaxial cable into the room to the modem, which in turn is connected to a computer, laptop or WiFi router.

It often happens that there is a 3G signal on the roof of the house, but it does not get into the room at all due to the complexity of radio wave propagation.

Consider the usual case - a signal with a level of -97 dBm comes from the base station on the roof of the house. If we put an AL-800/2700-8 antenna with a gain of 8 dB, then a signal with a level of -92 dBm will come to the modem input, because about 3 dB is lost on the cable and adapter to the modem (the loss in the cable depends on its length and on the marking). Based on our previous experience in measuring the speed of the Internet, we get a speed of 1.8 Mbps. And if we put AP-1900/2700-17 as an antenna with a gain of 17 dB!, then the modem input will receive a signal of -83 dBm, which corresponds to a speed of 7.7 Mbps.

If the signal on the roof of the house is from -85 dB and higher, then an antenna with KU = 7 -10 dB will suffice. At the same time, it must be remembered that in case of bad weather conditions it is necessary to have a certain reserve.
Once again I remind you that in each case the speed will be individual. And it may turn out to be much less, due to the low bandwidth of the base station of the cellular operator.Active 3G and 4G Signal Amplifier

Now consider the use of the TAU-2000 active amplifier. The connection diagram looks like this:

If you are faced with the need to amplify the 3G signal in your country house (or other object), then before buying antennas and amplifiers, you need to make sure that there is a 3G signal.

To do this, it is necessary to determine the presence of a third generation network with a phone that supports the 3G standard and SIM cards of various mobile operators and make an elementary signal measurement. Only after that, having previously made simple mathematical calculations, you can choose the right equipment.

Also, this amplifier model is very useful when using long cable lengths from the antenna. For example, on an 8D-FB cable at 3G (2100 MHz), the attenuation is 23 dB, and the gain of the amplifier is 40 dB. In other words, with a fairly good signal level from the BS, you can use a cable length to the modem of more than 100 meters!

In addition, TAU-2000 can be used as a 3G repeater for small spaces or inside a car. The coverage area strongly depends on the incoming signal from the BS and reaches a maximum of 15 sq.m.

If 3G "catches", then there is the possibility of obtaining a stable connection. In the article, we will consider how an external antenna for a 3G modem is installed, which is also characterized as a signal amplifier for a 3G modem. How to assemble it from improvised materials and strengthen the network signal.

An antenna for a 3G modem bought in a store is not a good idea, as it is expensive and not suitable for everyone and not everyone has an antenna connector. In addition, a modem adapter sometimes costs as much as the modem itself.

The main criterion for the effectiveness of any solution should be considered not the percentage displayed by the modem control program, not the number of “sticks” on the indicator and decibels, but the increase in access speed.
However, to confirm the correctness of the choice, you can use these criteria. It should be noted that the ability to connect to the 3G Internet depends on many factors - slot occupancy, subscriber activity, weather conditions, distance to the base station. In this case, the actions are aimed at improving only one.

The effectiveness of the antenna can be checked as follows - turn on the 3G or 4G mode and see if it catches. If not, then there is no data transfer, respectively.

In this case, the signal level can be both excellent and weak. Excellent level means that only 2G connection works.
Signal booster for 3G and 4G modem

The easiest option is about four turns of copper wire that need to be wound around the modem. Craftsmen advise winding the wire at the very end of the modem, where the built-in antenna is located.

Such a wire construction is like an art - you need to choose the number of turns, the thickness of the wire, the length of the free end of the antenna for each individual modem and location. For example, an extra turn may not improve, but only worsen the signal.

The second option is to use a colander or pan. Fans of experiments, whom the low speed of the Internet has already driven to rage or despair, are able to make very unusual designs in the form of pots, screens and satellite dishes.

It is easier to catch a 3G or 4G signal with a saucepan than with a wire, but it will take more time.
The third option is to use industrial items. Those who do not feel sorry for money within 500 rubles can experiment with these items. However, such aggregates do not differ much from wire in quality.

Sometimes an extension cable with a piece of tape is included with the modem in order to fix it to a wall or window. This option can be found in the operator's manual. Its quality can be compared with the quality of wire.

DIY antenna for 3G and 4G modem

The idea of ​​using canned antennas has moved into mobile communications from the Wi-Fi network, where craftsmen are able to stretch networks over fairly long distances.

So, you need to find an empty tin can. A coffee can will do.

At the calculated distance from the bottom of the jar, it is necessary to make a hole and fix a standard antenna socket in it, to which the waveguide is soldered.

Then connect the TV cable with the appropriate braided connectors and the antenna adapter to the modem.

It is worth considering the situation when the modem does not have a socket for connecting an antenna. Of course, you can open the modem, find the measuring socket on the board, solder a thin wire with a connector to it, thus making an adapter for an external antenna.

A gadget for obtaining mobile access to the Internet is an optimal device that has become a constant assistant to many people using the World Wide Web. The main differences from the router are the increased ease of use, because the USB device is portable and you can take it with you anywhere. Many mobile operators provide their customers with the opportunity to use the Internet not only on mobile devices (smartphone or tablet), but also on computers and laptops. Megaphone is no exception. A very important indicator is the quality and speed of the Internet. When users discover that the Internet speed has dropped, a logical question arises - “How to increase the speed of the Megafon 4G modem?”.

Signal quality: what does it depend on, how to check?

What factors most strongly affect the quality of the Internet provided by a usb device? So, how high-speed the Internet is depends on:

1. Distances from the communication tower of the operator.
2. The fact that there are wireless devices nearby (they may cause interference).
3. The proximity of large-scale production, factories, landfills. Some of the listed objects jam the connection.
4. Room insulation, wall thickness.
5. weather conditions. In good weather, the speed of the Internet 4G modem increases.
6. Computer/laptop software. A system with overloaded operating memory and viruses will itself slow down the data transfer process.
7. Operator tower congestion.

How to check the Internet speed if the user feels a significant decrease in it? To do this, he can use various sites, or look at the computer / laptop itself for information about the connection status.

How to increase the signal?

How to improve the signal of a 4G modem from Megafon? The most popular methods include:

• Moving a laptop / computer with a connected device closer to the window.
• Buying a USB extension cable. With it, the usb - device can be placed on the windowsill from the side of the street.

• Buying a factory signal amplifier.

• Self-made creation of a reflector (a device created from improvised means that can increase the signal).

If the Megafon 4G usb modem has a low speed, remember that you can try to fix the situation yourself. How to strengthen the signal of a 4G modem megaphone with your own hands? With the help of a special antenna, which can be created from a metal can. Also, an extension cord and scissors for cutting metal are used for work.

Stages of creation:

• We connect the usb device through an extension cable.
• We cut a small hole with scissors, but sufficient to fit inside the device. If the incision is too small, it can be enlarged.

We fix the device inside.
