Now I will tell you about ways to organize mobile Internet outside the city, for example, in the country, and also about how to strengthen a weak 3G signal with your own hands so that the reception is stable and reliable.
Working on the Internet, you get a valuable opportunity to do business from almost anywhere, that is, you are not tied to any one office or city and can freely travel, relax outside the city and at the same time continue to go online and earn money here (see all benefits of making money online).
Of course, many experienced users have long ago decided on the necessary equipment for these purposes (for example, there are 3G signal amplifiers from the manufacturer VEGATEL (https://www.vegatel.ru/), but many novice Internet specialists or businessmen are still just encountering with the need to organize fast and stable Internet outside the city.
I have been living outside the city for several years now and I can share some of my experiences that may be useful to you, especially if you are just starting to master the network and mobile Internet 3G/4G/5G, as a convenient means to achieve these goals.
I’m not a “techie”, so you won’t find any purely technical calculations here, soldering diagrams for 3G signal amplifiers for a modem and the like, because 99% of people who find themselves face to face with the need to organize the Internet in their dacha or simply strengthen 3G signal will never solder anything - they need a simple ready-made solution.
My advice is simple and can be implemented by almost every mobile Internet user. But first, you still need to answer the question:
How to boost a 3g modem signal using speakers
The first option on how to strengthen the signal of a 3g modem with your own hands, which you can try at home without extra expenses and effort, is to use ordinary sound speakers. Mobile Internet users noted that if they move them closer to the modem, the signal level increases by 10-20%. This is not very much, but with poor connection quality it gives a noticeable increase. To get rid of annoying clicks from the speakers, you should turn the sound to minimum.
What is the MIMO standard and how is it used in a 4G radiator?
Literally, if we translate Multiple Input Multiple Output, this means “Multiple Input Multiple Output”.
Note! The very basis of this technology is solved by encoding the spatial signal, where there is an increase in the bandwidth of the bandwidth where the data transmission takes place. In other words, the signal itself is expanded due to the amplification of parallel antennas
In other words, the signal itself is expanded by amplifying parallel antennas.
Quite often, the same new generation Multiple Input Multiple Output (MIMO) technology is used in Wi-Fi, thanks to which the data transfer speed is more than 300 Megabits per second. In addition, as a result of which the wireless network began to transmit the necessary information faster where signal reception is very low. In 4G, and Wi-Fi speed has become over 300 Mb per second.
The high specificity and stability of the connection at long distances from the station is the highest success of MIMO.
Note! The point of nanotechnology is to distribute the flow into several channels, then they can be sent along different paths through several antennas and run independently. If the transmission goes through two channels of the same information with a delay, then it is possible to restore the lost symbols on the receiving side, which improves the signal-to-noise ratio to 10-12 dB
Accordingly, this technology leads to increased speed
If the transmission goes through two channels of the same information with a delay, then it is possible to restore the lost symbols on the receiving side, which improves the signal-to-noise ratio to 10-12 dB. Accordingly, this technology leads to increased speed.
For the channel section, polarization is used. In a Wi-Fi network, this technology operates in the IEEE 802.11n and IEEE 802.11ac standard and is supported by many devices. There is such a term as “cable assembly”. This is a cable connecting the antenna and the device that transmits (modem, router). To correctly select the desired assembly, you need to know the exact distance from the antenna itself to the device.
Since the operating range of the 4G network almost coincides with the range of the previous generation, there will be no difficulties in operating in 3G 4G LTE networks. This allows you to bring the data transfer speed closer to the maximum. The design of the 4G modem itself involves the use of MIMO technology.
Signal amplifier for 3g modem made of copper wire
Another way to easily boost the signal of a 3g modem with your own hands will require a little more action than the option with speakers. You need to make a structure from wire and a tin can that will serve as an antenna. The algorithm of actions is as follows:
- Take copper wire (preferably a long piece).
- Open the gadget and make 5-6 turns around the SIM card.
- Pull the other end to the window.
- Take a tin can or cut off the neck of a beer bottle to create a “glass.” It will act as a reflector that enhances communication.
- Wind the free end of the wire to the bottom of the can.
- Turn the neck in the direction where the nearest operator tower is located. The increase in Internet quality will be up to 90-95%.
Laserdiscs
An equally effective signal amplifier can be obtained from a regular laser disc.
And everything is done very simply:
- The hole in the center of the disk is enlarged to the size of a USB adapter.
- Then the modem is threaded into it and connected to the USB cable.
For greater efficiency, it is recommended to place the disk with the modem outdoors, preferably higher. But here you need to start from the length of the cord.
How to strengthen a 3g modem signal using network settings
Before making antennas with your own hands, you should try another method on how to strengthen the signal reception of a 3g modem. Some mobile Internet users do not know that by default, when the connection quality is poor, the device automatically switches to 2g communication mode, which is not possible to work normally with. 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 a 3g connection. How to change an option:
- run the network setup program;
- select the “Connection” tab (or with a similar name);
- Next, the network search mode needs to be changed from automatic to 3g.
This will force the device to work only on these frequencies, without dropping the connection to a lower speed one. Some modems do not have such an item in the application interface for the device. In this case, you should look for a combination to activate the built-in command in the device instructions or on specialized forums. Each modem model has its own programmed order for enabling the option.
Necessary theory
Everyone can guess that the longer the wire, the more likely it is that the signal will be lost in it. Even if you use a high-quality and expensive cable when assembling a gun, signal loss is possible. The cable is a key part of the antenna, so in the process of choosing it you cannot adhere to the residual principle, otherwise the advantages of the most effective gun will be negated.
For example, if one type of wire can be used in a region with low frequency, then its use in high-frequency areas is no longer possible. To reduce cable losses, it is necessary to reduce its length and the concentration of high-frequency connections.
Note! If the 4G antenna gun will operate at high frequencies, a cable with higher performance should be used when assembling the structure
Boosting a 3g modem signal with a USB extender
This is not the best, but it works, how to easily boost the signal of a 3g modem with your own hands. It is well suited for people who do not want to disassemble or re-solder their device. The design works on the principle of a satellite dish. To make it, you need to buy a “reflector” (jar, bowl, CD), a 3-meter female-to-male USB cable. The creation process is as follows:
- In the middle of the disk, make a mount for a flash drive, or tape it with tape.
- Connect the cable at one end to the computer and the other to the modem.
- You can use a stick instead of a holder or simply attach the disk from the street side to the facade of the house.
- Point the flash drive in the direction where the signal is strongest.
The increase in connection quality is not very large, because the USB cable loses some of it due to its length, but still improves the connection. The mirror surface of the CD acts as an amplifier. It is recommended to use a bowl instead of a disc because its reflective surface is larger and the reception will be even better. Enameled options are not suitable; use stainless steel products.
Method 4: Purchasing a guide antenna
For anyone who does not want to build their own antennas, or for those who are simply not satisfied with this option, we recommend that you resort to ready-made solutions, which are called guide antennas. They can be difficult to find because not all electronics stores carry them. Therefore, you may need to order online or go to a radio market. Look at the parameters and technical characteristics of available devices and choose the best one for yourself. Do not hesitate to consult with the seller to get practical advice.
Special external signal amplifier for 3g modem
Operators are aware of communication problems, so they are constantly trying to expand their coverage area. As an intermediate solution, for example, a 3g signal amplifier was created for the Megafon modem and other companies. This is an antenna that operates at the required frequencies, and you need to connect it directly to the device. When choosing a model, you should rely on the radiation pattern and gain.
For the antenna to work effectively, it must be pointed towards the mobile operator tower that is closest to your home. Attach the stand so that the pins are perpendicular to the ground. Please note that the longer the cable, the greater the signal loss along its length. A short cord will provide a sufficient increase in communication provided it is of good quality. If you bought an amplifier, then you shouldn’t skimp on the cable.

How to boost a 3G signal with your own hands using a repeater
The most effective is amplification using a special device - a 3G repeater. Boosting is only possible if the phone receives at least a minimal 3G signal. This approach can be called completely professional, since after installing the repeater you will receive:
- maximum possible 3G signal amplification;
- the maximum speed of mobile Internet that a mobile operator can provide;
- stable reception area within the coverage radius of the internal antenna;
- getting rid of problems that arise when the signal is weak: connection interruptions, subscriber unavailability, interruptions during a conversation, and others.
A repeater is a cellular and Internet signal amplifier for a dacha, house or apartment, which itself is only part of a 3G signal amplification scheme. To create a full-fledged system, you will need an external antenna that picks up the cellular operator signal from the base station and an indoor antenna that “distributes” the cellular signal to subscribers indoors. All this is switched by coaxial cable. In difficult cases, boosters, attenuators, splitters and other equipment may be needed. In ordinary cases, for example, to strengthen the 3G signal in a country house or in a cottage, it is enough to buy a ready-made kit, for example VEGATEL VT-3G-kit. This kit is optimal in terms of price/quality, it works reliably and can be easily installed with your own hands. VEGATEL equipment is manufactured in Russia and has all the necessary certificates.
How to measure your speed
Before you move on to checking the speed, you need to find out if the device is connected to the Internet. You can do this by opening the command line. In it you need to enter the command ping 8.8.8.8. If the answer is positive, the size and validity period of the packages will be indicated. After this, you can proceed to checking the information transfer speed.
You can complete this process by following the following instructions:
- open your browser, enter the query “Check speed” in the search bar;
- follow the provided links to any resource;
- press the “Check” button or any other key that is responsible for this work;
- wait until the check is completed.
After completion, the user will receive a form where the results will be presented, including the maximum signal transmission speed.
If, using Internet resources, it turns out that the speed of receiving and transmitting information is less than 80% of that which was presented in the contract with the operator, you need to contact the provider’s support service.
How to strengthen the signal reception of a 3g modem with an internal antenna
Another option on how to strengthen the 3g modem signal with your own hands is to use additional devices to connect to the internal antenna. Each such device has it, but in some the connector is open, you can easily connect to it, while in others it is hidden in the case, and to use it you will have to resolder part of the device. In the first case, you just need to buy an amplifier or use a television antenna as a receiver.
If the connector does not exist, then you can take the device to a service center, where for a reasonable fee the technician will make it possible for you to connect a repeater, which will improve communication with the nearest operator tower. The main disadvantage of the method is that it will no longer be possible to use the modem only with an internal antenna, so you should only take this step if you know for sure that you will no longer need it.
What does Internet speed depend on?
The quality of reception is assessed using the decimal logarithm of the ratio of the amplitude of the received signal to the amplitude of the selected pulse, this is called the gain, measured in dB. The presented indicator may be influenced by the following environmental factors.
- The distance traveled by a radio wave to the nearest communication station. The larger it is, the longer the period of time spent on delay and absorption will be, that is, the speed will be less.
- The presence of walls and other obstacles in the signal visibility range. Radio radiation can be absorbed by concrete, wood, various metals and water. This means that the presence of these materials and substances in the path of the wave will significantly weaken the signal from the receiving station.
- Presence of noise in the frequency band. Each radio frequency channel is endowed with a limit of dedicated lines; the denser they are, the greater the likelihood of their intersection. Accordingly, additional speed violations will appear.
- Quality of receiving equipment. Much of the work depends on the accuracy of the receiving antenna. This is due to the fact that the frequency of cellular stations has a high level of accuracy, regardless of the gigahertz range. That is, if there is an error in the antenna assembly of at least 1 mm, then its resonant functions will be impaired.
- Modem location. Signals will be transmitted much better and faster if you place the equipment near windows or on the top floor of a building.
The presence of wireless devices in the signal area may cause interference, which will affect the transmission speed.
Based on the above, we can say that the quality and speed of the Internet is influenced by many factors. Therefore, by eliminating most of them, you can significantly increase the data transfer speed. However, before doing this, you need to analyze the existing connection.
