Jammer-MartNovember 2022
The working principle of the wifi jammer is simply that the frequency emitted by the jammer itself interferes with the normal frequency of the mobile phone receiving the router, making the mobile phone unable to connect with the base station, and thus unable to make calls, text messages and surf the Internet normally. The current wifi signal jammers are all frequency bands, which can block all 2G 3G 4G signals, 2.4G WIFI signals, and Bluetooth signals under the three operators of China Mobile, China Unicom, and China Telecom.
