We rarely think about security in general and digital security in particular. However, there are times when circumstances force us to keep something or hide from others, using special devices. Suppressors (jammers) Wi-Fi signal - devices just from this series. It is not a basic necessity for the majority, but an indispensable thing under specific circumstances. If you need such a device, check out the review of the best Wi-Fi signal jammers prepared by the editors of the site "bestx.htgetrid.com/en/".

Application area
The sphere of using these devices is not so narrow as it might seem at first glance.
Many large companies keep their secrets from competitors, so they need to have secluded (in all respects) places. Meeting rooms, conference rooms, top management offices - all these premises can be a source of expensive information that needs to be protected.
The educational institutions where the exams are held are secondary schools, vocational schools and universities. There is an official requirement of the Ministry of Education of the Russian Federation to suppress wireless communication channels during state exams. However, in intermediate tests for pupils and students, educational institutions can use the same measures, albeit at their own discretion.
Government agencies, from special services to regional administrations, are also sources of "unwanted dissemination" information, therefore, it is quite reasonable to use such devices.
Metro stations and trains are also often equipped with such equipment in order to combat the terrorist threat. Since it is possible to block the remote activation of explosives.
Radio signals also interfere with the functioning of certain medical devices. Therefore, many medical institutions also install such jammers.
Operating principle
It is a compact box. Its size varies depending on additional functions and range. It prevents the transfer of any information over wireless channels.
The most common Wi-Fi frequency standard is 2.4 GHz. There are 13 channels at this frequency, the blocker sends signals to all channels at once, thereby blocking them all with constant interference. The so-called "white noise" is created and the communication of the devices within the radius is completely stopped.
This can affect not only the harmless router of neighbors, but also various bugs and security cameras.
Radius of action
For most factory models, this figure is within 20 - 30 meters. However, there are special devices capable of working at a distance of up to 200 meters.
Terms of use
There are currently no rules in Russian legislation that regulate the use of such devices in sufficient detail. However, if you have it, you need to register it with the State Commission on Radio Frequencies in the manner approved by the decree of the Government of the Russian Federation No. 539 of October 12, 2004. Otherwise, a fine is provided - for individuals - 500 rubles with the confiscation of the device, for legal entities - up to 10 thousand and also confiscation.
What are
Depending on certain indicators, Wi-Fi signal suppressors are classified as follows:
- Multi-frequency. Allows you to adjust both the frequency of suppression and its strength. This variety is the most powerful of all sold. They can block both Wi-Fi frequencies and GSM and GPS.
- Stationary. The current option for installation in a company office or government agency. Confident work - for the whole building. Some models allow blocking signals up to 200 meters away. Average power range.
- Portable. The simplest and most compact. They do not have outstanding performance in terms of strength and range of work, but they do an excellent job of working locally. They can be installed in a subway car, a cafe or a waiting room.
Criterias of choice
The device is quite simple to operate, but you need to understand a few points in operation. In order not to get confused with the choice and choose the best option for yourself.
- Pay attention to the operating frequency range and choose those that best suit your needs. Of course, the functionality can be expanded by adding antennas to the device, but this can significantly increase its cost.
- Radius of action. When calculating the possible range, take into account the nominal value declared by the manufacturer and the obstacles from the walls that will surround the device. The material and wall thickness make it difficult for the suppressor to operate smoothly
- If the device is powered by a battery, evaluate its power, these devices are very sensitive to the amount of energy received.
- The smaller the device, the smaller its radius of operation and power, but more options for use due to mobility and autonomy.
How to do it yourself
If you have some knowledge and do not want to spend money on purchasing a factory jammer, you can do it yourself at home. Of course, the result obtained can hardly be used for official activities, but it is quite suitable for performing local tasks.
The first option is if you have an unused router. You will need a separate router and client. With their help, you can transfer a large amount of data to the receiving device, thereby overloading the channel and blocking it completely.
There are several more options for assembly schemes, freely walking around the network on thematic portals.
Their essence boils down to connecting several simple components into a single device. To do this, you will need:
- antenna acting as a transmitter;
- voltage controlled generator;
- radio frequency amplifier;
- jammer.
However, I would like to warn against rash use of such products. The fact is, with it you will not only block someone's neighbor's router, but, first of all, you will affect the performance of the devices at home. In addition, at present, it is quite simple to detect the source of radio signal interference, and this is fraught with unpleasant showdowns, up to explanations with the police and, as noted earlier, fines and confiscations.
Next, let's take a look at the best Wi-Fi jammers for 2020.
