Review of the best Wi-Fi signal jammers for 2020

Wireless Internet is not only the speed and convenience of data transfer, but also the ability to get unauthorized access to your information, photos, videos, accounts and passwords. It is enough to simply make an illegal connection to a laptop or install a hidden tracking device and unprotected information will become the property of intruders. Avoiding data leakage will help buying a muffler for wi-fi networks.

WI-FI jammer is a device that blocks the transmission of any information over a wireless communication channel. It is used to protect closed conferences, confidential business meetings, for exams in schools and universities, at sports events, at premieres of films and theatrical performances.

What is a WI-FI jammer: more details

Equipment in a compact package that operates at 2.4 MHz. The interference range varies from 15 to 30 meters, depending on the model. Allows you to control wireless networks within the declared radius in order to completely secure the surrounding area. Almost all spy equipment operates at frequencies in the 2.4-2.5 MHz range, the jammer will neutralize any device in the specified frequency range. When connecting this unit, please note that wireless keyboards, mice and other bluetooth technology will stop working.

The first device was invented and manufactured relatively recently, in 2001, by order of the King of Jordan. The incumbent king was very annoyed by phone calls during prayer in the temple. He turned to developers at Image Sensing Systems. Soon, the first sample of a cellular jammer was presented. Over the years, the equipment has been improved and is used in various industries, including the military, in order to protect itself from wiretapping and to avoid interference with aircraft and helicopters. Today, you can buy a gadget in a specialized off-line or on-line store. The cost depends on the functional quality of the internal components. You should not chase very budget jammers, in 90% they stop working in a month or two.

Where are signal jammers used?

  1. In the offices of large companies, in meeting rooms. Ensure confidentiality of the meeting and prevent information leakage.
  2. Medical institutions install such equipment when wi-fi networks interfere with the normal functioning of medical equipment.
  3. In cinemas for closed and premiere screenings of films, in order to save the merging of a new film into the network.
  4. In educational institutions so that students are not distracted by browsing sites or tips on the Internet.
  5. In living quarters to drown out a neighbor's wi-fi.

The Wi-Fi muffler can work in any conditions when the use of wireless Internet is prohibited or undesirable. In the range of operation, the operation of devices transmitting or receiving a signal is blocked. The device is put into operation by pressing one button, there is no need to additionally configure the signal or install software.

Varieties of WI-FI suppressors

The devices are divided into several groups depending on the configuration and functions:

  1. Portable.
  2. Stationary.
  3. Multi-frequency.

Portable jammers are housed in a small, lightweight body. There is a battery inside, the capacity of which directly affects the operating time of the equipment without recharging. The range of pocket models is up to 10 meters.

Stationary suppressors - are installed mainly in medical, educational institutions, to maintain signal silence. They have a large coverage - 30 meters or more.

Multi-frequency blockers - suppress any type of signal, not just wi-fi. They work from a 220V network. These devices provide a function for adjusting the frequency of the band and adjusting the suppression power.

How to choose a signal suppressor

Several selection criteria that need to be considered when choosing a device:

  • The dimensions of the device, depending on where it will be used, choose a portable, pocket suppressor, with a range of 10 meters - for your own use. If you need an office device, consider stationary models.
  • The radius of action, consider when choosing the thickness of the walls in the building, the distance of the device from the source that needs to be damped.
  • The number of working frequencies, most of them block not only Wi-Fi, but also GPS, GSM standards. A separate antenna on the device is responsible for each frequency; if desired, you can turn off or turn on the dummy of the necessary signals.
  • The battery capacity affects the duration of the device operation and the quality of signal blocking; the larger the capacity, the longer the continuous operation will be.

The cost of portable devices is from several thousand rubles. You can choose a customized signal suppressor at an inexpensive price. Stationary and multi-frequency models are more expensive, but more functional.

How to place a stationary suppressor

A few tips for use:

  1. To increase the radius of signal suppression, it is recommended to install the device at a height of 1.5-1.8 meters above the ground.
  2. It is not recommended to turn on the device without connected antennas. Check the numbering of antennas and connectors on the case.
  3. Do not cover the device during operation.
  4. Make sure there is sufficient ventilation in the room where the muffler is located.
  5. Be sure to turn off the jammer from the network after work.
  6. To cover a large room, over 20m2, use multiple devices.

Do-it-yourself jammer, is it possible?

Yes, if you have simple soldering equipment and a circuit, you can make a muffler with your own hands. A homemade device will not be as presentable as the conveyor model, it will be less functional, but the neighbor's wi-fi signal will be able to muffle. The scheme of a home-made device is easily searched for on the network. Components required:

  • Generator;
  • Antenna;
  • Cascade for amplification;
  • Tuning circuit with a jammer.

A homemade device is useful for home use. In large rooms, it will be useless.

The rating is based on consumer reviews, taking into account a comparison of characteristics and prices. We advise you to stop the choice on models of a domestic manufacturer in a plastic case, if you need a portable jammer, and in a metal one - a stationary one. Also, when choosing a portable model, you should give preference to one that eliminates one type of signal, be it the Internet or cellular communication. But a stationary device, on the contrary, is better to buy one with more frequencies. We do not recommend buying Chinese devices, as they often lose the suppression frequency, it is impossible to notice this without special equipment. Russian models do not have such defects.

After purchase, the device must be registered with the State Commission on Radio Frequencies. For individuals, the use of an unregistered suppressor is punishable by a fine of 500 rubles. and confiscation. For legal entities - a fine of up to 10,000 rubles. and confiscation. The use of an unregistered jammer is not imprisoned, except for those cases when the equipment caused an accident, car theft, etc. The registration service is absolutely free, you can submit an application electronically, by invitation. Will have to appear twice. The first time - to enter data about the device, the second time - for a certificate of registration.
