With the release of Pokemon GO this summer, the number of fans has soared. An augmented reality and virtual effect game hunts about 151 Pokémons in towns, all of which are hunt by smartphone or tablet, including some Nintendo characters such as Roucool, Carapuce, Bulbizarre, Salameche, Pikachu, etc.
In order to maintain public order in the classroom and prevent students from investing a lot of time in the game, the Ministry of Education is considering installing WiFi jammer in educational institutions at the beginning of the school year. The device can prevent the transmission and reception of GSM 3G 4G mobile phone signals and wifi waves, and can block the reception of the network within a certain range (classroom or test room), including sending information, photo sharing, and network video browsing.
This means that teachers and students are unable to use mobile phones and computers for a certain period of time, which may affect the educational work within a certain range, and therefore requires special permission from the department. In fact, in the United States, it is prohibited to illegally use any equipment designed to interfere with invalid electronic communications. It can only be used in some military, security headquarters, prisons and even theaters.
WiFi jammers are generally used indoors. In order to reduce the speed of wifi connections, we can also use them in public places, such as some large conference rooms, churches, etc. Hackers use tube software to invade your phone through your wifi connection, steal information that is useful to you, or protect privacy. These things are common.
