Our school has installed a mobile phone signal jammer. I thought of a cracking method. I bought a portable wifi. Can my mobile phone connect to the wifi to access the Internet?
Now the standard cell phone jammer on the market can block all the 2G 3G 4G signals and 2.4G WIFI signals of all operators' mobile phones. frequency, so as to achieve the purpose of shielding them. When 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.

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.
