What if the cell phone signal is interfered

What if the cell phone signal is interfered

  • 2022/07/09

Method 1: due to the rapid development of wireless network, it has now developed to 5g network, and many examination rooms use older frequency jammer, and there is nothing to do with 4G and even the current 5g network. Cracking method: there is no 2G network using 4G or 5g card.

 

Method 2: Bluetooth cracking method. It is suitable for short-distance communication in the shielding area. Some shielding devices may ignore the transmission function of Bluetooth and have no shielding, so we only need to install Bluetooth messaging software on the mobile phone to communicate normally in a small range. With the rapid development of the network, frequency jammer are also being upgraded. All radios can be shielded by adding the frequency band of the known network to the interference.

Method 3: band decoding method. Because the working principle of the school's frequency jammer is to interfere with the frequency jammer of the specified band, so as long as you modify the receiving and transmitting frequency of the mobile phone, you can prevent it from being shielded. The shielding device only shields the mobile phone signal of 900-1800mhz, while the receiving and transmitting frequency of the mobile phone is 850-1900mhz, which is far greater than the shielding range of the shielding device, So as long as the reception and transmission frequency of the mobile phone is adjusted to the maximum in the mobile phone settings, the mobile phone signal can be received normally.

Method 4: WiFi cracking method. This method has high requirements for the environment, and the premise is that there must be an available wireless network around. Some mobile phone signal shields can't shield WiFi signals and can realize communication with the outside world.
