GPS jammers provide more than just communications protection. These GPS jammers are able to point out small problems in the network signal. GPS jammers keep frequencies free from any interference. Entrepreneurs and employees are also protected from any intrusive measures employed by database scammers. Multifunctional blockers set the tone that all forms of information are essential, whether personal or business.
In addition to GPS jammers, there are several other types of jammers, the best of which are great for individuals and organizations.
Portable jammer is an excellent cell phone jammer that can effectively block signals on the move, this portable jammer is not expensive. Portable jammers are so important that the jammer doesn't interfere with the work of any other electrical or electronic products around it. This feature of the portable jammer makes it easy to use without any limitations. In addition, the portable shield is easy to carry and easy to carry. Therefore, ideal for individuals, portable jammers come in different models and sizes.
Also, there is the 4G/5G blocker, which blocks all mobile phone signals from anywhere in the world. A 4G/5G blocker is a very efficient and sophisticated device, it is a powerful device that can block signals up to 20 meters. The 4G/5G dongle can be operated with battery and adapter. Therefore, the 4G/5G jammer can be used both indoors and outdoors. That is, the advantage of such a shield is that the installation position can be selected. 4G/5G shields are more convenient shielding devices.
The shielding distance of the device has a great relationship with the power of the device and the use environment. There are several aspects that help the shielding effect: one is the output power of the device, the second is the working method of the shielding, and the third is the use environment (indoor or outdoor), The fourth is to shield the interference intensity of the surrounding environment.
Nowadays, mobile phones are all digital signals, and digital signals have strong anti-interference ability. Generally, analog signal technology is used to interfere with digital signals. Therefore, digital signals must be used to interfere with digital signals. The interference effect is very different. The jammer using digital interference signal technology has lower power and higher efficiency than the jammer using analog signal interference technology.
The analysis of synthesis, attenuation and reflection of indoor mobile phone signals and interference signals is very complicated. Before shielding, the strength and quality of mobile phone signals in the local space 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. The general spatial signal strength is about -60 to -70dbm, the base station can reach about -40dbm within a few hundred meters, and the mobile phone reception strength range is generally between -35 and -95dbm. The higher the power of the mobile phone signal in space, the shorter the shielding distance.
The above is a conclusion 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 used as a qualitative reference, especially indoors. The above law is very different from the actual situation. Therefore, this problem is very difficult-accurately calculated at one time and can only be determined according to the actual situation on site. Precise construction projects must carry out preliminary research and signal testing, and then design specific solutions. In the later stage, timely follow-up tests are required, and certain corresponding supplements can be made to be foolproof, that is, to achieve the effect of strict shielding.
