Using mobile phones at oil station¡¢gas filled station, oil depot will cause fire or blast, which brings serious consequences.
1.4 As a new criminal measure which affects the stability of society.
Some people use mobile phones to cheat at the exams while terrorists and hostiles use mobile phones to fire bombs etc. It is certified that mobile phones have become a kind of tool for committing crimes under some situations, and have made adverse effect on the stability of society.
The mobile phone signal isolator developed by our company can efficiently solve the above problems. As a new type of information security product, it can form an electric hedge around the places to be protected by special electromagnetic signal ,whereby mobile phones can not receive any information form their base stations, or can not communicate with their base stations thus eliminate the negative effect of mobile phones.
