How to strengthen cellular signal on the modem. Is it possible to strengthen the USB modem signal from megaphone

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

How to enhance the 3G modem signal using audio columns

The first option, how to strengthen the 3G modem signal with your own hands, which can be used at home without excess spending and effort - use ordinary sound speakers. Mobile Internet users noted that if you pose them closer to the modem, the signal level rises by 10-20%. This is not very much, but with poor quality of communication gives a tangible increase. To get rid of the annoying clicks from the speakers, the sound is worth minimizing.

Signal Amplifier for 3G Copper Wire Modem

Another way how to enhance the 3G modem signal with your own hands, will require you slightly more actions than the option with speakers. You need to make a design of wire and tin cans that would perform the role of antenna. The algorithm of action is as follows:

1. Take a copper wire (preferably a long piece).
2. Open the gadget and make 5-6 turns around the SIM card.
3. The second end will reach the window.
4. Take a tin jar or cut off the beer neck to get a "glass". It will perform the role of a reflector that enhances the connection.
5. Take to the bottom of the jar of the free end of the wire.
6. Turn the neck to the side where the nearest operator's tower is. The increase in the quality of the Internet will be up to a level of 90-95%.

How to enhance the 3G signal modem network settings

Before you make antenna with your own hands, you should try another method, how to increase the reception of the 3G modem signal. Some Mobile Internet users do not know that by default, with low quality connection, the device automatically switches to 2G communication mode, with which it is not possible to work normally. In this case, the transition occurs even if there are 2-3 "sticks". To avoid such situations, you should clearly indicate through the device settings that you only need to use 3G connection. Procedure for changing the option:

1. run the network setup program;
2. select the "Connection" tab (or with a similar name);
3. next, the network search mode must be changed from automatic on 3G.

This will make the device work only at these frequencies, without dropping the connection to less speed. Some modems do not have such a item in the device interface for the device. In this case, you should search the combination to activate the built-in command in the instructions for the device or on specialized forums. For each modem model, the option is programmed.

Strengthening the 3G signal of the USB extension

This is not the best, but working method, how to easily enhance the 3G modem signal with your own hands. Suitable good for people who do not want to disassemble, overpass their devices. The design works on the principle of satellite plates. For its manufacture you need to buy a "reflector" (bank, bowl, CD), USB cable "Mama dad" 3 meters. The creation process is as follows:

1. In the middle of the disk, make a fastening for a flash drive, or take it with a scotch.
2. Connect the cable with one end to the computer, and the other to the modem.
3. You can use a stick instead of the holder or just fasten the disc from the street on the facade of the house.
4. Direct the USB flash drive in the other side where the signal is the strongest.

The increase in the quality of communication is not very big, because the YUSB cable loses some of its part due to length, but still improves the connection. The role of the amplifier is the mirror surface of the CD. It is recommended to use a bowl instead of a disc, because its reflective plane is greater and the reception will be even better. Enameled options are not suitable, use stainless steel products.

Special external 3G modem signal amplifier

Operators know about problems with communication, therefore they are constantly trying to expand the coverage area. As an intermediate solution, for example, a 3G signal amplifier for a modem megaphone and other companies was created. This is an antenna that works at the required frequencies, and it is necessary to connect it directly to the device. When choosing a model, it should be based on the indicators of the focus diagram and the gain coefficient.

For effective operation of the antenna, it must be sent towards the Mobile Operator's Tower, which is closest to your home. Secure the stand so that the pins are perpendicular to the earth. Consider the larger the cable length, the greater the signal loss at its length. The short cord will provide sufficient increase in communication under the condition of its good quality. If you bought an amplifier, you should not save on the cable.

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

The most effective is the gain with a special device - repeater 3G. Strengthening is possible only if the phone catches at least the minimum 3G signal. This approach can be fully professional, since after installing the repeater you will receive:

• the maximum possible amplification of the 3G signal;
• the maximum speed of the mobile Internet, which is capable of providing a mobile operator;
• zone of stable reception within the radius of the coating of the internal antenna;
• getting rid of problems arising from a weak signal: Communication breaks, unavailability of the subscriber, interrupts during the conversation and others.

The repeater is, at home or apartments, which in itself is only part of the 3G signal amplification scheme. To create a full-fledged system, an external antenna will be required, which captures the signal of the cellular operator from the base station and the room antenna, which "distributes" a cellular signal to subscribers indoors. All this commutes a coaxial cable. In difficult cases, boosters, attenuators, splitters and other equipment may be needed. In normal cases, for example, to enhance the 3G signal at the cottage, it is enough to buy a ready-made kit in a cottage, for example Vegatel VT-3G-KIT. This kit is optimal by the price / quality criterion, it works reliably and can be easily installed it with your own hands. Vegatel equipment is produced in Russia and has all the necessary certificates.

Causes of the weak 3G signal

All cases of weak or unsure reception of the 3G signal can be divided into two large groups. The first and most obvious is the remoteness of the user from the base station (tower) of the cellular operator. The second case is to reduce the quality of communication indoors.

Most often, this problem occurs outside the cities: in rural areas, at the cottages and in other places located at the 3G coating border. In addition to the distance to the tower, the landscape play a negative role: the height differences, forest arrays and other obstacles reduce the signal quality, so that it comes to the user in a substantially weakened form.

In turn, the direct visibility of the base station or long-term smooth areas of the landscape - factors favorable to distribute radio waves. For example, forest belts reduces the quality of the signal, but the presence of a lake, river or fields for it is much more preferable to a solid forest extending up to the tower itself.

Reinforced concrete structures and walls, overlaps and even window glass extremely negatively affect the signal strength. As a result, even in the city center, the connection may easily loosen or completely disappear if you descend to the underground parking or go to the office building. Even if on the street, mobile devices capture 3G on perfectly and show all five sticks, the quality of communication in buildings and premises can be unsatisfactory.

In all listed cases, an 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: to enhance the signal, it should be present at least at the minimum level in the planned place of installation of the antenna. It is not possible to strengthen the signal that is not, and start preparing to enhance communication, it is necessary to search for the place of the most confident reception.

Frequencies and 3G communication standards

Before you begin to strengthen mobile communications, you need to understand which signal you plan to strengthen. All radio equipment - from simple antennas to repeaters and boosters - designed for certain frequency bands. Some devices support more bands, others - less. Usually there is no need to strengthen all existing radio frequencies: it is unnecessarily expensive and simply do not need. It is much more efficient to learn which frequency bands you are required for work. This will allow not to buy universal expensive equipment and restrict ourselves to the profile devices suitable under your case.

The overwhelming majority of 3G base stations in Russia operate in the frequency range of 2100 MHz. The 3G standard corresponding to this range is commonly called UMTS-2100. 3G-networks are transmitted both voice communication and mobile Internet, therefore the increase in the frequency range of 2100 MHz is most often the optimal solution.

Since modern smartphones choose the preferred communication standard automatically, in situations of unsure reception of the 3G signal, they often "jump" between 2G and 3G modes. Such behavior leads to interruptions in the work of voice communication and unstable work of the Internet. As a rule, in the phone you can prohibit switching, manually selecting one specific standard, but it is associated with additional inconveniences. For example, by selecting a high-quality GSM (2G), you deprive yourself a 3G Internet, and vice versa, choosing an unstable 3G, risk to face interruptions in conversations.

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

3G signal strengthening methods

Depending on whether the quality of the 3G-Internet is required to improve or also need to strengthen voice communication, various approaches are applied.

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

Nevertheless, this method has a number of significant restrictions. First, the router and modem provide access to smartphones, tablets and computers to the Internet, but do not enhance the voice communication itself. Thus, if there are problems in your whereabouts and with voice communication too, the installation of the router will not solve them.

Secondly, a separate SIM card is required for modems and routers. Using the modem, you can connect one device with a USB port to your mobile Internet using a router to organize a WiFi network to connect multiple wireless devices. Nevertheless, a third-party person who came from the street will not be able to connect from the smartphone to the 3G Internet of its operator: you will first have to provide it with access to WiFi.

When you need to provide access to the 3G-Internet directly from mobile devices or improve voice quality, do not avoid installing the strengthening system with repeater and internal antenna.

Below we will look at both methods.

Strengthening with a router / modem and external antenna

To strengthen 3G-Internet, it is enough to install an external antenna and connect it to a compatible router or a modem. Antenna is placed at the point of the most confident signal reception, preferably in the direct visibility of the base station. For country sites, this is the roof of the house or a special mast. In the city, it is enough to bring an antenna to the street: it can be fixed on the balcony or on the outer wall of the building.

The antenna itself enhances the signal and transmits it by a router or a modem. Coaxial cables are used to connect devices, for example, or. Also in our online store you can purchase with sold-up connectors. It is desirable that the cable length does not exceed 5-10 meters. For connecting antennas, N-type or SMA connectors are most often used.

3G routers have a slot under the SIM card and in the setting, as a rule, are not very different from ordinary home routers for wired Internet. Most of the 3G routers presented today are on sale, support WiFi and allow you to configure a wireless local network. We recommend our customers with a 3G / 4G router, who has proven itself as a reliable and inexpensive solution for the house and office.

A more budget option is a set of an ordinary home router with a USB port and a compatible 3G modem. Configuring the modem after connecting to the router occurs automatically and does not require user intervention. In the GSM-repeater store.ru you can purchase tested for compatibility kits, for example,.

In the case of the use of the modem, special adapters are added to the scheme -.

Pigeons - Adapters for connecting antennas to modems with CRC9 connectors (left) and TS9 (Right)

Selection and installation of external antenna

The cellular signal has vertical polarization, and with incorrect antenna arrangement, the quality of communication will suffer greatly. As a rule, an antenna housing is placed a polarization polarization (usually arrow), according to which it should be positioned in space. In the absence of an arrow, the polarization pointer can be the name of the antenna (the inscription must be readable).

For installation it is best to use that will simplify the further adjustment and adjustment of the antenna. The antenna itself should be sent towards the base station of the cellular operator. Find out which operators work at your location, you can with help on our website.

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

HUAWEI E3372 web interface allows you to view the current level of the signal in Decibelas (DBM)

OpenSignal and NetMonitor applications

OpenSignal and NetMonitor - Applications for smartphones, allowing you to view the level of the current signal in decibels (dB) and quickly locate the nearest base station. Data on links of cellular operators is replenished by users themselves, so the base is always up to date. OpenSignal is available for Android and iOS operating systems, NetMonitor - android only.

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

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

OpenSignal and NetMonitor (right) applications help determine the signal strength and location of the nearest base station

We recommend using OpenSignal and NetMonitor to determine the signal level and antenna adjustment. Knowing the power of the signal in decibels and the location of the tower is easier and avoiding errors when it is installed and configured.

Reinforcement

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

In these cases, it is necessary to install the reinforcement system. The principle of operation of such a system is quite simple: the external antenna catches the signal and transmits it on the cable to the repeater, which enhances it. The enhanced signal is transmitted to the inner antenna that distributes it to the room. The outgoing stream is intensified in the same way: the signal from the subscriber enters the inner antenna, enhances the repeater, is transmitted to the outer antenna and emitted in the direction of the base station.

The area of \u200b\u200bthe refirator coating directly depends on its power. For domestic use in most cases, there is enough repeater with a capacity of 50 MW with a gain of 65 dB. An excellent solution for the ratio of price and quality is the repeater from the well-known domestic manufacturer. To cover the house of a large area and / or with a weak input signal, more powerful devices are used, such as (75 dB, 200 MW) or (80 dB, 500 MW).

Repeators are also different from the supported frequency bands. To enhance 3G, you just need to purchase an amplifier with the support of the range of 2100 MHz, but in some cases it makes sense to think about the purchase of multi-band repeater.

For example, the use of repeater with frequency ranges 900 and 2100 MHz will simultaneously improve GSM (2G) and 3G, and the two-band model 2100 and 2600 MHz will provide support for 3G and 4G. The most expensive repeaters allow you to strengthen all used cellular standards at the same time.

With all its versatility, repeater also have several restrictions. The main thing is due to the fact that the external antenna is sent to the tower of a specific cellular operator, and if the rods of other operators are in the opposite direction, their signal will not enhance. In such a situation, in order to enhance the signal of several operators, you will have to install several directed antennas connected to the repeater via splitter.

The second limitation is associated with the "side effects" of analog gain. Radio signal always contains some percentage of interference, which are also enhanced by the repeater. With a weak signal, the proportion of interference can be significant, which will lead to the noise of the outlet. The gain will still occur, but the quality and speed of communication may be lower than the initially predicted.

Conclusion

We will summarize and theses once again tell about the gain of the 3G signal:

• Unable to increase the signal that is not. To enhance any signal, it is required to capture the technique.
• The main causes of the weak cellular signal are remoteness from the base station and various obstacles to radio wave.
• In Russia, 3G communication in the overwhelming majority operates in the range of 2100 MHz. All equipment to enhance 3G must support this frequency range.
• Only mobile Internet or mobile Internet can be strengthened together with voice communication. To enhance only the Internet, the external antenna and 3G router or modem. To also strengthen the voice 3G communications, you will need a reinforcement system.
• The outer antenna must be sent towards the tower of the cellular operator. To find out the arrangement of the tower, use the OpenSignal and NetMonitor smartphones applications. When installing an antenna, observe its polarization.
• Antennas are connected to devices using special connectors. For connecting to the repeater, the N-type connector is used, to the router - SMA, to modems - CRC9 / TS9. To connect an antenna to a modem, a special adapter is also required - pigtail.
• The 3G repeater performs the function of amplifying the signal coming from the external antenna and transmits the reinforced signal to the inner antenna located indoors.
• Repeaters are single-band and multi-band. To enhance the 3G communication, there is enough single-band repeater with support for the UMTS-2100 standard. Multidiaband repeaters allow you to strengthen several communication standards simultaneously and create a back for the future (for example, providing support for 4G).

Today, 3G is considered one of the most popular types of communication, which allows us to access the Internet from almost any place in the city and even for its feature.

However, this type of communication has its own problem - this is a coating. Even despite the fact that broadcasting is carried out by almost every cellular tower, dead zones are very often found, and in cities. What to talk about remote settlements.

Almost the only way out in this situation is an independent gain of a 3G modem. Amplifier can be made independently, and you can buy already ready in the form of a remote antenna. Below we will tell about several ways to enhance the 3G modem signal.

Option 1 - Place a modem on the window or on the street (the easiest)

If you set a 3G modem on the windowsill (using a USB extension), or climb with a laptop to the roof, then in some cases the signal quality may increase by about 10-15%.

At least this method is the easiest, but it has quite a few flaws:
Little speed increase
Binding to someone (not always convenient)
USB signal attenuation extension
There is no possibility to improve the quality of telephone.

2. Using a reflector from remedies

This method is the most popular in mind its simplicity and low labor cost.

Here, the 3G modem amplifiers will serve things that can be found in any house. This is a kitchen pan, ordinary colander or any tin can.

The gain principle is that the modem is placed inside the reflector focusing the signal on the modem. Now it needs to be connected to a computer, which should be nearby, in view of the fact that the long cable causes the signal attenuation. The real increase from this method is about 15-20%.

The disadvantages of the reflector are in its bulkness, relatively weak gain and in the attenuation of the signal.

3. Strengthening 3G modem using the Harchenko antenna

This method is more complex requiring certain skills and understanding the principles of microwave.

For the manufacture of such antenna, you will need: a wire, a thickness of 3 mm, a metal tube (preferably copper), pliers, a file and a soldering iron. The process of making antenna you can find on the network. The advantage of such an antenna lies in a tangible strengthening - up to 50%. That is why it takes great popularity. Of the flaws, it is worth noting the relative complexity of its manufacture, since in such an antenna, the accuracy of the size plays a decisive role. If the dimensions do not correspond to the necessary, the antenna simply will not work.

Something recently my Internet provider in the office is constantly falling off. Not once and not two was the situation when I was forced to leave home, since there was no access to the Internet.

It is worth noting that I hate to work at home. And, frankly, I do not understand people who work exclusively from their apartments.

That is, they live at home and tear the veins too from the house \u003d) I had such an experience for 2 years, which remained the most gloomy memories. And I am still convinced that work, as many jokes, "in shorts in front of the monitor" sooner or later leads to a protracted depression.

Fortunately, I did not reach this extreme. And immediately removed the office as soon as such an opportunity appeared in early 2013. Yes, I understand perfectly well that far from everyone is ready to make offices, but nevertheless, I sincerely recommend not to sit in four walls. This is the path to depression.

I pay 6500 per month for my humble shelter. And I do not think that this is a big fee for preserving yourself in the right mind and hard memory \u003d)

Well, okay, I distracted from the topic

After the Internet access situation was repeated several times, then I decided to connect the modem from some cellular operator. Found the old MegaFon modem E-173. I connected and with despondency observed an extremely low access speed at the EDGE level.

She looked at the office and found the most optimal location of the laptop.

Of course, for confident reception, it was necessary to keep it on the elongated hands in the upper right corner of the window. It was worth it to move half a way as the speed dropped sharply.

I was already ready to go after a wireless router with support for SIM-cards to hang it in the magic and confident access point, but accidentally found a USB extension.

I connected the modem through the extension cable and hung at the desired point.

Surprisingly, it works.

Though I worked in a cellular connection, but I was sure that it would not help. I still remember how a magical support specialist cheerfully broadcast me that the signal will fond or will not reach the laptop at all, since "a lot of interference".

There is no interference, everything is perfectly plowing. True, the speed did not rise above 2 megabits, but for the backup channel of communication is enough.

The extension itself costs about 120-200 rubles at any computer store.

What is me for?

Yes, to the fact that it is not necessary to blindly believe all sorts of specialists and a guru, who confidently carry any incomplete. It is necessary to try and test any opportunity, even if it seems complete nonsense. And the whole story with a USB extension cord is a visual confirmation, since I thought to the last thing that it would not help, because the "signal blows".

The network of "green" operator, as well as any other, applies unevenly. Somewhere devices catch the Internet better, somewhere worse - and then the question arises than and how to strengthen the MegaFon modem signal. You can buy a device specially created for these purposes, but it is too simple and assigned. It is much cheaper to build an antenna from undergraduates, especially special knowledge and skills for this.

Signal Amplifier for Megaphone Modem

Compact operator modem, although they allow you to stay in touch away from home Internet, but sometimes give low connection speed or refuse to see the network at all. Affect this most different factors:

• distance to the nearest cellular tower - how it further, the worse there will be a signal;
• the density of the environment and the number of walls separating from the street is part of radio waves when passing into the building or through obstacles are absorbed. That is why we observe a weak signal in basements, metro and large shopping centers;
• natural phenomena - precipitation and even foliage on trees affect communication;
• duration of the day - the Internet speed falls if a large number of users go to the network at the same time. Similar can be observed at lunch when people are distracted from worries, or in the evening when they come from work;
• computer specifications. If they do not comply with 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 at 2-3 "sticks" of the antenna. With a hint of a bad connection, it does not work at full speed. To refuse to go to 2G, go to the modem program, find the "network search mode" in the "Connection" tab and select the name with the name like "Always 3G".

Before you are withdrawal and try to enhance the 3G Modem "MegaFon" signal at home, check if the device does not interfere with something listed. Change the conditions: From the middle of the room, go closer to the window, go out to the street or send a router towards the tower. If simple actions do not help, reserve tools, materials and start collecting the antenna.

With sound columns

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

Consider only that an annoying buzz is distributed in the speakers in the speakers. If you are going to try out the way, reduce the sound to a minimum in advance.

From copper wire

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

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

First, open the can with canned food. The top cover cut completely to get the semblance of a glass. Content eat or give to households, and rinse the tank and dry.

Remove the protective cover from the router. One end of the wire is hosted tight in the SIM card area. Another wrap around canning cans. Post the last part through the window posting on the street and direct an improvised glass on the tower. Insert the modem into your computer and try to connect.

The video is more complicated, but a powerful homemade antenna. The author gives detailed instructions for the manufacture and collects the design on the camera for visibility.

USB extension

If there is no copper wire at hand, use the permissible "megaphone" modem amplifier as a USB cable. Buy cord of suitable length. One end stick to the computer, in the other insert the router. Position the last part so that the signal is improved - send outside the window or secure under the ceiling.

To protect the modem from snow and rain, people make special holders from undergraduate funds. The same tin tank or plastic bottle is suitable for this.

• Canned cans need to get rid of the top cover, rinse and dry. Closer to the bottom, shift the vertical rectangular hole in the size of the end of the USB extension agent, which comes into contact with the modem. Insert the cable, connect the router - it should settle down within the bank. The edges of the hole fill with glue from the gun or close the tape for the water inwards. Open top tighten the film.
• For the second option, take a plastic bottle, 3-4 unnecessary compact disks, 2 old plastic cards, the glue "second", a stationery knife, sandpaper, thermocons. Cut about a third of the bottle from the neck. Discs fold chamomile, overlay space. Treat the sandpaper for better clutch and glue the "second".

Take one card, put a router on it and tick the outlines of the device. Long sides of the credit card bend by marks to get like a scoop. The second card on one of the short sides, move the centimeter - it will be the fastening of the future holder. Spread the blanks by the reverse parties. For the holder, at the middle of the "chamomile" from the disks.

To equalize the edges of the bottle, lay them with a hot knife. Put the modem on the holder, stretch the cable through the neck of the bottle, connect to the device. Stick the edges of the container to the disks of the thermoclaster - the plastic cap will protect the router from the rain. After it remains only to attach an improvised antenna to the window, insert the other end of the extension to the computer and connect to the Internet.

With the help of repeater

If you make an amplifier with your own hands there is no possibility, you can save a ready-made repeater. The device is a special antenna that improves the quality of receiving the signal from the base station. You do not need to configure the repeater - just turn on the outlet, connect with the modem and work.

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

Similar devices for sale on Chinese sites, in official stores of the operator and network trading points specializing in the technique. Stand, depending on the characteristics, from 500 to 1500 rubles. At https://shop.megafon.ru you can find the popular Ramo "Connect 2.0" and Ramo LTE Mimo Indoor. For 650 and 999 rubles, respectively, according to customer reviews, in suitable conditions increase the speed of 5 times.
