Today, I learned from Chongqing Mobile that Chongqing Mobile has established a special group of experts for the protection of college entrance examinations, which aims to ensure the wireless shielding effect of each test center and achieve the goal of "precise shielding". According to the relevant person in charge of Chongqing Mobile, since the college entrance examination centers in the main urban area of ​​Chongqing are all within the urban area, the installation of a large number of full spectrum Block Cell Phone Advertising Calls will have a certain impact on the network usage of surrounding users. The mobile phone manifests as the phenomenon of searching the network, no signal, no service system, etc. Therefore, during the college entrance examination, the call quality of mobile phone users around the test center will also be affected, or there will be no signal, frequent call failures, inability to connect, intermittent calls, and slow Internet access on mobile phones. If you encounter a similar situation during the exam, for the sake of fairness and impartiality in the exam, Cell Phone Jammer may let you have a period of no network around you.

This year, the mobile company has taken a number of measures to increase the investigation of surrounding fake base stations to prevent criminals from using the psychology of the parents of candidates during the college entrance examination to send illegal and false information such as cheating and training. At the same time, in the layout stage of the college entrance examination Block Cell Phone Advertising Calls , check and test the coverage of mobile phone jammers in advance with the examination room department to ensure the effective and reliable interference. In addition, the antenna adjustment, power optimization and new functions for alleviating the interference of mobile phone jammers are also opened in the surrounding area of ​​the examination room, so as to control the interference range of the mobile phone signal jammer within the examination room as much as possible, reduce its interference extension to the surrounding area, and improve the non-interference ability. The network perception in the test area enables "precise shielding" of mobile phone signals within the test room. After testing by the wireless network optimization personnel of Chongqing Mobile, compared with the previous non-exam period, the noise floor of the interference in the test center has increased by 16db, and the shielding ability is stronger and the accuracy is higher. At the same time, thanks to the efforts of the mobile company, a total of 5 illegal mobile pseudo base stations have been identified in the city, nearly 100,000 illegal text messages have been reduced, 156 antennas have been adjusted, 440 power parameters have been adjusted, and 335 cells have been opened with new functions.
