The key to shielding 4G network signals depends on the frequency supported by the selectedย jammer communication. The current 4G frequency range is very wide, from 800M-2. 4G. If you want to shield 4G signals, it depends on what you use in the jammer. How much bandwidth can be supported. Because some of the 4G frequency band almost overlaps with WIFI 2.4. Once you shield the 4G signal, the WIFI and Bluetooth in the shielded area may not work properly. Therefore, whether the 4G signal can be shielded depends primarily on the function of the shielding product, and whether the device has a 4G signal shielding module.
