Shielding Tester helps quickly test shielding cases, boxes, and other Faraday Cage devices. The application measures the GSM/2G/3G/4G, Wi-Fi 2.4/5 GHz, and Bluetooth signal strength and provides extensive data on the shielding device’s radio signal inhibition performance (in dBm). After every test, you get a report that you can save or send to the manufacturer of the shielding device you tested.
