Rating of the best cell phone jammers in 2020

Cellular suppressors are a device that suppresses specified frequency ranges. The device creates interference that prevents cell phones and spy devices from working properly. Under its influence, it will not be possible to transfer information from one gadget to another.

What is the purpose of the suppressor

Any mobile device can be listened to. This does not require the owner's consent. A large number of programs have been invented, with which you can control the microphone and camera in any phone. And this can be done remotely. The owner will not suspect that he is being tapped. After all, there will be no changes in the operation of the phone, indicating the fact of espionage. Any secret information can be recorded and dropped using a simple mobile phone. You don't even need special spy equipment.

Turning off the phone completely will not save you from listening. A person can be spied on, even if the cell phone is taken offline. Modern methods allow eavesdropping on any gadget. Therefore, if a person suspects that he is being monitored, then you can use a mobile communication damper. By connecting such a device, you do not have to worry about your safety.

There is another good reason why you need a communication suppressor. This is to ensure the silence during public speaking. If the speaker is annoyed by phone calls, beeps and melodies while delivering a speech, then you can use a neutralizer. The device will provide a fertile environment where the audience will not be distracted by extraneous noises of mobile phones.

Application of communication absorbers

Signal jammers are used to neutralize wireless communication channels 3G, 4G, Bt, Glonass / gps. This is usually done in places where the use of the ranges listed above is prohibited or desirable.
In some cases, cellular dampers are used as protection during negotiations. The device can be used both separately and in systems of mass protection of conversations in office buildings.

The weak point of any mobile phone is the microphone. From a long distance it can be activated using special means, and then eavesdrop on all conversations in the office where the gadget is currently located. Therefore, any mobile phone in our time is a device for transmitting and reading information.If a person has access to classified materials, then he will have to protect his phone with a communication jammer. Confidentiality of negotiations is impossible without the use of a damper.

Communication damper characteristics

Before choosing a device, it is worth knowing which parameters to pay attention to:

Range of action

The distance over which cell jammers work varies. The range of operation largely depends on the power of the device and the distance between the base station of mobile operators to the radiation source of the phone damper. Typically, devices for jamming cellular communications are produced with a range of 2 to 50 meters.

One and the same signal neutralization device located in different parts of the same building will produce a different damping effect for certain telecom operators. This suggests that the power of the wave from the base station differs in different parts of the premises.

Strong suppressors are more expensive than their less powerful counterparts. When buying such a product, you need to check it. You will need to test all the functions of the device on your territory. Indeed, in different conditions, the device can produce a different range of action. The user needs to make sure that the purchase suits him in all respects.

Principle of operation

Signal suppressors are produced in circular and directional action. The first ones work on a certain diameter near the apparatus. The latter act on a specific place, emitting a signal in a strictly defined direction. Therefore, when choosing a wave damper, it is necessary to take into account the distribution radius and the range of the directional signal effect.

By execution

Modern manufacturers produce outdoor stationary and portable units.

Stationary communication jammers

Stationary suppression devices are needed to jam a signal of a certain frequency range along a given radius, provided that the power supply is constantly supplied from the 220 V network. Another power option is a car cigarette lighter or other methods of supplying electric current. The installation of the signal muffler is carried out indoors and is moved in rare cases. This is due to the size of the device. In most cases, such devices are used:

• in office buildings to ensure the secrecy of the conversation and prevent data leakage;
• in a theater, museum or other cultural institution to provide silence;
• in educational institutions during an exam or test.

Small Silencers (Portable)

Small devices stand out for their dimensions, due to which they are easy to transport and will always be there. The battery charge allows you to block the signal while on the road or where there is no fixed electrical network.

For portable devices, signal jamming occurs within a small radius, which allows for personal safety not to affect others. Another criterion in their favor is low cost. All this expands the possibilities of application:

• to block the signal at home so that children do not sit on their phones for a long time;
• in order to prevent information leaks;
• in public transport so that the driver is not distracted by loud conversations;
• small devices block the signal of listening devices, GPS trackers, GLONASS satellites, bugs.

The best models of stationary suppressors

There is no specific device that is better at everything. Each suppressor is good for a specific task that can be accomplished with it. Here we will talk about the devices that are in the greatest demand among consumers, indicating the features of the devices.

Alligator 80 exam

A novelty for suppressing mobile phone signals - "Alligator 80 Unified State Exam" allows you to block cellular signals and data transmission via the mobile Internet in classrooms and offices during examinations or important negotiations. The prototype is the successfully implemented model "Examiner 80 Unified State Exam".The new model is more expensive, but it also has more options. Suitable for use in classrooms, universities, company meeting rooms.

Experts advise to mount the device at the highest point of the office or room away from metal structures that can serve as a screen. Before mounting, you need to attach the supplied antennas and adjust the settings for each band. When operating a suppressor in a small room or room, it is worth setting half the power or a little more so that the suppression radius does not go beyond the office, interfering with other office inhabitants.

Which signal suppressor to choose

It is almost impossible to answer such a question, because it is necessary to take into account and consider each case on an individual basis. If it is necessary to protect the office of the company from eavesdropping on competitors or other people, it is better to choose communication mufflers with a long range. The same should be done during the exam, to eliminate the signals of the mobile phones of the examinees. Therefore, it would be better to use stationary, more powerful mufflers.

If the device is to be used for personal purposes, then a portable silencer will be enough. The range of such a device is quite enough to ensure personal safety.
