In recent years, with the rapid development of communication technology, Mini Cell Phone Jammer Circuit equipment has also been used in examination rooms to prevent cheating in examinations, holding secret meetings, explosion-proof gas stations and other important places that need to implement radio control. The application of mobile jammer equipment has become more and more important. sex. The use of mobile phone signal jammers in the exam is one of the common radio management methods. I saw the latest full-featured mobile phone signal jammer in the 2010 National Judicial Examination Examination room that just ended. The purpose of using mobile phone jammers is to prevent the use of mobile phones to shield devices such as miniature transceivers. Mobile phone signal jammers can effectively shield all communication signals including 3G signals, mobile phone signals, walkie-talkie signals, and radio signals. cell phone jammer
With the continuous advancement of science and technology, Mini Cell Phone Jammer Circuit devices are constantly being updated. The latest mobile phone signal jammers developed in the market can shield all mobile phone frequency bands, including the newly launched 3G 3 frequency bands, using a segmented shielding method. Interfering with the downlink signal does not affect the uplink signal of the mobile operator, and does not cause pollution to the electromagnetic environment. Can avoid unnecessary disputes and influence on the public. The technology and functions of mobile jammers are constantly being improved and improved, and the concept of environmental protection and energy saving has also penetrated into this industry. The regulation of manufacturers of mobile phone jammers will play a restrictive role, and will be more conducive to the market supervision of mobile phone signal jammers. With the popularization of radio knowledge and strengthening people's correct understanding of mobile phone jammers and other regulatory equipment, I believe there will be better development!
