With the development of society and the improvement of science and technology, some technologically advanced cheating methods are widely known, which makes it more difficult to maintain the order and discipline of the examination room. In order to ensure that all kinds of behaviors such as cheating using mobile phones in the examination room are completely solved, the role and advantages of mobile phone jammers are fully utilized.

Under the same conditions, the worse the working environment of the mobile phone jammer, the stricter the requirements for it. It can detect the field environment, test the local signal strength, which signals are included and which signals need to be interfered, and select the interference equipment with strong power. After all, the effects of mobile phone jammers with different field environments and configurations will be different. On the contrary, the effect of equipment with the same environment is not obvious, so it must be overhauled or the frequency band should be set. Make reasonable arrangement according to the communication signal principle, the field environment and the influence of nearby base stations, so as to reduce the factors affecting the interference range of the mobile phone jammer, and significantly improve the interference effect of this jamming device.

Nowadays, with the continuous progress and development of society, there are advantages and disadvantages. The development of science and technology brings convenience to people and also brings some unnecessary troubles. The mobile phone jammer has always had a good performance in jamming the mobile phone signal. The jamming technology has been applied very mature in practice, which is the most intuitive performance of the jamming device.
