Multifunctional signal jammer, suitable for different interference purposes

GPS jammer not only provide communication protection. These GPS jammers can point out small problems in the network signal. The GPS jammer keeps the frequency free from any interference. Entrepreneurs and employees are also protected by any intrusive measures used by database crooks. Multifunctional shields set the tone, making all forms of information indispensable, whether it’s personal or business information.

In addition to GPS jammers, there are several other types of jammers, among which the best jammers are very useful for individuals and organizations.

The mini jammer is an excellent mobile phone jammer that can effectively block the signal while on the move. This portable jammer is not expensive. The portable jammer is very important. The jammer will not affect the work of any other electrical or electronic products around it. This feature of the portable jammer makes it easy to use without any restrictions. In addition, the portable shield is easy to carry and easy to carry. Therefore, it is an ideal choice for individuals. Portable jammers are available in different models and sizes.

In addition, there is a 4G jammer, which can block all mobile phone signals from anywhere in the world. The 4G jammer is a very efficient and complex device. It is a powerful device that can block signals up to 20 meters long. The 4G jammer can be operated with batteries and adapters. Therefore, 4G jammers can be used indoors and outdoors. In other words, the advantage of this shield is that the installation location can be selected. 4G jammer is a more convenient shielding device.

The shielding distance of the device has a great relationship with the power of the device and the use environment, and several aspects that are helpful to the shielding effect: one is the output power of the device, the other is the working method of the shield, and the third is the use environment (indoor or outdoor). The fourth is to shield the interference intensity of the surrounding environment.

Mobile phone signal jammer

Nowadays, mobile phones are all digital signals, and the anti-interference ability of digital signals is very strong. Generally, the effect of using analog signal technology to interfere with digital signals is poor. Therefore, digital signals must be used to interfere with digital signals. The interference effect is quite different. The jammer using digital jamming signal technology has lower power and higher efficiency than the jammer using analog signal jamming technology.

The synthesis, attenuation, and reflection analysis of indoor mobile phone signals and interference signals is very complicated. Before shielding, the strength and quality of local cell phone signals have a great impact on shielding. Different mobile phones have different effects. Generally, mobile phones with strong ability to receive weak signals may not have good anti-interference effects.

The direction of the base station and the direction of the shielded area of ​​the mobile phone also affect the shielding effect. Generally, the spatial signal strength is about -60 to -70dbm, and the base station can reach about -40dbm within a few hundred meters, and the mobile phone reception strength range is generally between -35 to -95dbm. The higher the signal power of the space mobile phone, the shorter the shielding distance.

The above conclusions are based on the law of radio signal transmission in free space. In reality, there are many obstacles on the ground that affect the transmission of radio waves. The above can only be qualitatively used as a reference, especially indoors. The above law is very different from the actual situation. Therefore, this problem is difficult to calculate accurately at the time, and can only be determined based on the actual situation on site. Precise construction projects must carry out preliminary research and signal testing, and then design specific solutions. In the later period, timely follow-up tests are required, and certain corresponding supplements can be foolproof, that is, to achieve the effect of strict shielding.
