After a case where a stranger scammed a mobile phone during a car driving test, the police station set up radio wave breakers at many driving test sites in October this year to block radio waves from mobile phones. The case was reported in May last year when a remote man cheated with a mobile phone and a small headset at the driving license examination site and illegally obtained a car driving license.
Jammer is a kind of signal blocking device, mainly including mobile phone jammer, GPS blocking, WiFi jammers, etc. The United States is the world's most commonly used WiFi jammer country. Second is Russia, where people strongly protect their privacy. The third is India, where people are used to using signal breakers in public places to avoid terrorist attacks.
Although the illegal use of jammer products is prohibited in many countries, the number of people using jammers in these countries is increasing. Before purchasing a wifi jammer, you must first check your local laws and then determine the cut-off frequency, which you must know before purchasing a jammer for use. All we have to do is shop with the laws in your country.
