Exams are an important part of teaching, but the use of mobile phones to cheat during exams has caused great concern. It is becoming more and more common for colleges and universities to use signal interference to prevent mobile phone cheating. This article briefly describes the business opportunities of signal jammers in the context of new technological innovations.

On February 4, 2017, the Ministry of Education announced the 41st Order "Administrative Regulations for Students in General Higher Education Institutions". Taking a university as an example, the number of 115 people who violated discipline and cheated on mobile phones in the 2018~2019 school year was 92 during the same period in the previous school year.

Since mobile phones are usually small in size and easy to carry, it is not practical to scan candidates in a large area before the exam to prevent candidates from using mobile phones to seek help from better technical sections. Because the teaching buildings of colleges and universities are usually large, the use of large-scale mobile phone signal interference equipment usually requires coordination with the local radio management committee. The coordination is inconvenient and the comprehensive use cost is higher. The plug-and-play small-range cell phone signal jammer used in the classroom is popular with colleges and universities because of its convenient use and storage.

The life of the cell phone jammer is completely determined by the innovation of mobile phone technology. Usually interference devices are backward compatible, but because of the leapfrog development of the mobile phone industry in my country in recent years, it took only about 5 years from 3C to 4G. These 3C mobile phone signal jammers have little effect in the face of the increasingly popular 4G mobile phones. It quickly became a display. To make matters worse, the 5C era has begun, and 4G jammers have not yet been popularized.

Of course, from another perspective, it also shows the vast landscape of 5G mobile phone signal interference equipment.
