Radon Transmits Communications Between Devices Using Ultrasonic Sounds
Android: We’ve already seen apps that allow you to share links with sounds . Radon brings a new twist to it by using sound waves that the human ear cannot hear.
The app works by leveraging the little-used ultrasound features in the Google Nearby API . Just open the app and you can send or receive links without having to manually pair devices, copy text, or scan QR codes. This is probably not something you want to use every day, but it comes in handy if you need to immediately send links to everyone in the meeting.
