Now the mobile phone signal blocker on the market can block all 2G 3G 4G signals and 2.4G WIFI signals of all mobile, Unicom and Telecom mobile phones as standard. Its principle is to interfere with mobile phone receiving base stations and wireless routers through its own frequencies The frequency emitted, so as to achieve the purpose of shielding them. After the school installed the device, once it was turned on, the mobile phones in the classroom were unable to communicate, text messages and surf the Internet normally. Even if you carry a WIFI with you, it will be blocked because its frequency is also within the shielding range of the wifi signal jammer. The only way is to use cell phone signal towers on site, because cell phone cell towers enhance cell phone signals, and jammers block cell phone signals. When cell phone towers are too close, the power of the jammer cannot match the To contend, most mobile phones cannot be blocked at this time.
Also, you need to know that the mobile phone card or the IoT card is also used for the portable WIFI, and the signal will also be blocked. And because the antenna of the portable wifi is generally shorter, the shielding is more thorough.
