The future market trend of the shielding device

The State Security Bureau, in cooperation with the Radio Management Committee of the Ministry of Information Industry, Northern Jiaotong University and other institutions, formulated the first industry standard, “Technical Requirements and Test Methods for Mobile Communication Jammers for Security Conferences”. With the guidelines relaxed, experts said the market potential of shielding devices is huge and the industry’s scope for development is extremely wide. At present, the global cell phone ownership has reached 2 billion. It is estimated that the demand for shielding devices is 1% of the total number of cell phones. That is, for every 100 mobile phone users, there is one shielding device user. This user can be It is a safe place, a secret place, a quiet place or a public place or a person.

The shielding system is not only used in high-level places such as arsenals, political parties, governments and military, public safety, finance and trade secrets, but it can also be used in places closely related to people’s lives. Experts believe that based on the latest usage analysis, the cell phone signal jammer market size could reach tens of billions of yuan.

The rapid development of modern communication technologies requires that companies of technological security keep pace with the times and continuously develop and strengthen their own strengths in order to meet the diverse challenges. The widespread popularity of cellular phones not only brings convenience to people, but also poses new problems for the security and confidentiality of communication. Eavesdropping, leaks, exam room fraud, medical accidents and gas station explosions occur endlessly and accelerate the shielding of cell phone signals. Promotion and use. It is mainly used in exam rooms, prisons, gas stations, cell phone bombing prevention, oil depots, liquefied gas stations, detention centers, interrogation rooms, courts, labor reform teams, conference rooms, theaters, churches, libraries, school dormitories, etc. for security and confidential occasions ( confidential offices, negotiation rooms, mobile vehicles, mobile politicians and dignitaries of companies) etc. as well as cell phone signal jammers are becoming increasingly important in social life.

Depending on the location, Jammer shop has designed and manufactured different kinds of jammers, designed and shielded different places, fully exploited the product performance, and greatly improved the effect of the jammer. It beats the crowd with its excellent performance. And received unanimous praise from the industry!

Within a certain frequency range, the mobile phone and the base station are connected by radio waves, and the data and sound transmission is completed with a certain baud rate and modulation method. The jammer scans from the lower frequency of the forward channel to the upper end at a certain speed during operation. This scanning speed can lead to garbled interference with the message signal received by the mobile phone. The mobile phone cannot recognize the normal data sent from the base station, so the mobile phone cannot connect with the base station and achieve the purpose of shielding the mobile phone signal. The mobile phone seems to be searching the network, no signal, no service system, etc.
