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

How to amplify a 3g modem signal using speakers

The first option is to use your own hands to amplify the signal of a 3g modem, which you can try at home without unnecessary waste and effort – use ordinary speakers. Mobile Internet users noted that if you 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 tangible increase. To get rid of annoying clicks from the speakers, the sound should be set to a minimum.

Signal amplifier for 3g copper wire modem

Another way to easily amplify a 3g modem signal with your own hands will require a little more action than the speaker option. You need to make a construction of wire and a can that would serve as an antenna. The algorithm of actions 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. Reach the other end to the window..
4. Take a can or cut off the beer neck to make a “glass”. He will act as a reflector, enhancing communication.
5. Wind the loose end of the wire to the bottom of the can.
6. Turn the neck to the side where the nearest operator tower is located. The increase in Internet quality will be up to the level of 90-95%.

How to amplify a 3G modem signal with network settings

Before you make the antennas with your own hands, you should try another method, how to strengthen the reception of a 3g modem signal. Some mobile Internet users do not know that by default, with a 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 in the presence of 2-3 “sticks”. To avoid such situations, it should be clearly indicated through the device settings that you need to use only the 3g connection. The 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 needs to be changed from automatic to 3g.

This will make the device work only at these frequencies, without resetting the connection to a lower speed. 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 instructions for the device or in specialized forums. Each modem model has its own order for enabling the option..

Signal amplification 3G modem USB extension cable

This is not the best, but working way, how to easily amplify the signal of a 3g modem with your own hands. Suitable for people who do not want to disassemble, re-solder their device. The design works on the principle of a satellite dish. To make it, you need to buy a “reflector” (a jar, a bowl, a CD), a USB cable “mother-to-father” 3 meters. The creation process is as follows:

1. In the middle of the disk, make a mount for a flash drive, or tape it with tape.
2. Connect the cable at one end to a computer and the other to a modem.
3. You can use a stick instead of a holder, or simply fix a drive from the street on the facade of the house.
4. Point the flash drive in the direction where the signal is the strongest.

The increase in communication quality is not very large, because the USB cable loses some of it due to the length, but it 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 reflecting plane is larger and the reception will be even better. Enameled options do not fit, use stainless steel products.

Special external modem signal amplifier 3g

Operators know about communication problems, so they constantly try to expand the coverage area. As an intermediate solution, for example, a 3g signal amplifier was created for the Megaphone modem and other companies. This is an antenna that works at the required frequencies, but 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 directed towards the tower of the mobile operator, which is closest to your home. Fasten the stand so that the pins are perpendicular to the ground. Please note that the longer the cable, the greater the loss of signal 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 should not save on cable.

How to amplify a 3G signal with your own hands using a repeater

The most effective is amplification using a special device – a 3G repeater. Amplification is possible only if the phone catches at least the minimum 3G signal. This approach can be called fully professional, because after installing the repeater you will receive:

• the maximum possible signal amplification 3G;
• the maximum speed of the mobile Internet, which is able to provide a mobile operator;
• stable reception area within the coverage radius of the internal antenna;
• getting rid of problems arising with a weak signal: disconnection, subscriber unavailability, interruptions during a call and others.

A repeater is a cellular and Internet signal booster for a summer residence, home or apartment, which in itself is only part of a 3G signal amplification circuit. To create a complete system, you will need an external antenna that picks up the signal of the cellular operator from the base station and a room antenna that “distributes” the cellular signal to indoor subscribers. 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 amplify a 3G signal in a country house or in a cottage, it’s enough to buy a ready-made kit, for example, VEGATEL VT-3G-kit. This kit is optimal by the criterion 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 strengthen the reception of a 3g modem signal with an internal antenna

Another option, how to strengthen the signal of a 3g modem with your own hands, is to use additional devices to connect to an internal antenna. Each such device has it, but some have an open connector, you can easily connect to it, while in others it is hidden in the case, and to use it you will have to re-solder 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 an acceptable fee the wizard will make it possible for you to connect a repeater, which will improve communication with the nearest operator’s tower. The main disadvantage of this method is that it will not be possible to use a modem only with an internal antenna, so you only need to decide on this step if you know for sure that you will not need it anymore..
