Review of the best Wi-Fi signal jammers for 2022

Wireless Internet is not only the speed and convenience of data transfer, but also the ability to gain unauthorized access to your information, photos, videos, accounts and passwords. It is enough just to make a forbidden connection to a laptop or install a hidden surveillance device and unprotected information will become the property of intruders. Buying a wi-fi network jammer will help avoid data leakage.

WI-FI jammer is a device that blocks the transmission of any information over a wireless communication channel. Used to protect private conferences, confidential business meetings, school and university exams, sporting events, movie premieres and theatrical performances.

What is a WI-FI jammer: more

Equipment in a compact package that operates at a frequency of 2.4 MHz. The range of interference distance 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 space. Almost all spy equipment operates at frequencies in the range of 2.4-2.5 MHz, the jammer will neutralize any device in a given frequency range. When connecting this unit, please note that wireless keyboards, mice and other Bluetooth devices will stop working.

The first device was invented and manufactured relatively recently, in 2001, by order of the King of Jordan. The current king was very annoyed by phone calls during prayer in the temple. He turned to the developers at Image Sensing Systems. Soon the first sample of a cellular jammer was presented. Over the years, the equipment has been improved and used in various industries, including the military, in order to protect against wiretapping and to avoid interference with aircraft and helicopters. Today, you can buy a gadget in a specialized off-line or online 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 jammers used?

1. In the offices of large companies, in meeting rooms. Ensure the 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 theaters at closed screenings and premiere screenings of films to keep the new film from leaking online.
4. In educational institutions, so that students are not distracted by browsing sites or can not find clues on the Internet.
5. In residential areas, to drown out the neighbor's wi-fi.

The Wi-Fi Silencer can work in any environment where the use of wireless Internet is prohibited or undesirable. Within the range, the operation of devices transmitting or receiving a signal is blocked. The device is activated by pressing one button, no additional signal settings or software installation is required.

Varieties of WI-FI jammers

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

1. Portable.
2. Stationary.
3. Multifrequency.

Portable jammers are made in a small, lightweight body. Inside there is a battery, 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 jammers - are installed mainly in medical and 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 220V network. In such devices, the function of adjusting the frequency range and adjusting the suppression power is provided.

How to choose a signal suppressor

Several selection criteria to consider when choosing a device:

• Dimensions of the device, depending on where it will be used, choose a portable, pocket jammer, with a range of 10 meters - for your own use. If you need an office device, consider stationary models.
• 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 jammed.
• The number of operating frequencies, most 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 both turn off and turn on the stub of the desired signals.
• The capacity of the battery affects the duration of the device and the quality of the signal blocking, the larger the capacity, the longer the continuous operation will be.

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

How to place a fixed suppressor

A few operating tips:

1. To increase the signal suppression radius, 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 coincidence of the numbering of antennas and connectors on the case.
3. It is forbidden to cover the device during operation.
4. Make sure there is sufficient ventilation in the room where the silencer is located.
5. Be sure to turn off the jammer from the network after work.
6. For coverage in a large room, more than 20m2, use several devices.

Do-it-yourself jammer, is it possible?

Yes, with simple soldering equipment and a circuit, you can make a muffler with your own hands. A home-made device will not be as presentable as opposed to a 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 on the net. Components that will be required:

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

Homemade device is useful for use at home. In large rooms, it will be useless.

The rating is based on consumer reviews, taking into account the 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, whether it be the Internet or cellular communications. But a stationary device, on the contrary, is better to buy one that has more frequencies. We do not recommend buying Chinese devices, since they often lose the suppression frequency, you cannot 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 jammer is punishable by a fine of 500 rubles. and confiscation. For legal entities - a fine of up to 10,000 rubles. and confiscation. For the use of an unregistered jammer, they do not go to jail, except for those cases when the equipment caused an accident, car theft, etc. The registration service is absolutely free, you can apply electronically, by invitation. You will have to show up twice. The first time - to enter data about the device, the second time - for a certificate of registration.
