Nowadays, wireless network technology has been very developed, which has greatly improved our lives, made communication more convenient, and promoted the rise of the short video industry. However, although information technology has become popular, it has also brought irreversible losses to some people's work. As time goes by, the mentality of the on-site staff has become more and more intense. At first, there were not many people participating in illegal gatherings, but with the help of mobile Internet and WeChat, people can easily contact the outside world, and more onlookers have joined, making the scene more and more difficult to control. It also brings many new challenges to the police's handling work. It also brings many new challenges to the police's handling work. At this time, the use of cell phone signal jammer equipment is indispensable. Controlling the communication signal at the scene can effectively reduce the gathering of people and reduce the detention time of people at the scene, which is of great benefit to the police's handling. The rapid development of social media has intensified the effective spread of false information and brought an unstable situation to society.

There is no trivial matter in the safety of explosive cases. The public security department configures mobile phone signal jammers. The core purpose is to prevent the threat of remote control explosive devices. With the full launch of 5G Internet, the data traffic charges of various operators have dropped significantly, and video communication software and online live broadcast platforms have developed rapidly. These software bring convenience and entertainment to people's lives. At the same time, they have brought a certain degree of interference to the law enforcement activities of the public security department.

At the scene of major cases in the city, it is difficult to ensure that there are no dead corners in the outer field blockade area. In some cases where the police must take sudden and strong measures, the live broadcast room on the scene is very easy to be seen by the suspects, and even criminals leak the police's action plan to the suspects through real-time video communication, which brings great passiveness to the police's behavior. Looking back, the communication jammer can carry out radio wave interference and shielding through multi-frequency electromagnetic waves with high transmission power, which can prevent the suspects from leaking information. It can also be used at the bomb disposal site to perform working frequency interference on the remote control explosive device, making it difficult for the explosive device to be detonated. #wireless jammer
