5G telephone signal blocker

Multi-band wifi jammer can organize mobile phones, WiFi, GPS signals, etc. at the same time. Cell phone jamming device send signals at the same frequency as a cell phone, thereby blocking cell phone services and preventing mobile devices from making calls or sending text messages. If the phone jamming device is running, your phone will not display network signals. WiFi interferers generate noise, block WiFi connections, and prevent people with WiFi devices from connecting to 3G, 4G, GPRS, or wireless WiFi networks. GPS jamming device is used to block satellite or spy equipment in the 1500 to 1600 MHz range. It is often used for decentralized surveillance or espionage.
