Science and technology have made great progress in the past few years. Now mobile phones are not only superfluous, but also a fashion. The current situation is that war zone operators and other war zones strongly demand the development of effective countermeasure technology. If you want to block it, you can use GPS jammers to limit calls and calls from mobile phones around you. We prevent the use of nuisance mobile phones and provide a quiet space and good etiquette. A simple and effective way is to use a mobile phone blocker. It is very effective in places where it is inconvenient to use mobile phones (places with poor environment).

As a measure to prevent harassing mobile phones, communication jammers are allowed in public places. In areas where jammers are active, your mobile phone will be in an "out of range" state. The public is in favor of this measure. It is expected that jamming will be implemented in the future, but the global mobile phone industry will naturally not remain silent. Measures are allowed to disrupt mobile phone communications in public places. Communication jammers prevent mobile phones from making calls, sending and receiving voicemails, and text messages. Civilians use communication jammers.

Mobile phone companies and mobile phone manufacturers are working hard to encourage responsible use of mobile phones. Improving the image of mobile phones will eventually bring profits to these companies. On the other hand, people are also worried that communication jammers may be abused. Unscrupulous retailers may abuse these devices. They are working to prevent mobile phones from being brought into the country. Currently, mobile phones in China cannot be used on a large scale. Many people use phones from two operators. The jammer is a GSM jammer that interferes with mobile phone calls, GPS systems, Wi-Fi communications, etc. I understand the desire to prevent people from using their phones while driving.

Some devices that interfere with mobile phone radio waves are sold on the market. It is easy to emit interference waves, but the problem is that the quality of interference waves is limited to a limited frequency range. I have read that you can use interference devices to disable GPS functions. We are also considering GPS tracking, but if they can be easily disabled, we will have to consider other measures. In theory, radio waves can be interfered with by continuously emitting radio waves with opposite phases to the radio waves, but of course, smartphones are equipped with Wi-Fi jammers that can emit such radio waves.

The strength of radio waves from mobile phone base stations varies depending on the location, but if you try to suppress the communication functions of mobile phones and other devices within a certain range, you can suppress them even in areas where the radio waves are the strongest. Common phone problems include "nuisance calls" such as silent calls and prank calls. This includes cases where we cannot reply to other customers due to too many nuisance calls. Recently, there are more and more people stuck in traffic jams. Unless the interfering radio waves are detected on the spot, that is, unless it can be proved that the interfering radio waves are being used at the time, it is difficult to capture them.
