The Silent Revolution: How Ultrasonic Waves Are Transforming Communication

Beyond the range of human hearing, a quiet revolution is underway. Ultrasonic communication—using sound waves above 20 kHz—is emerging as a powerful alternative where radio frequency (RF) technologies fall short. Whether it’s enabling secure proximity-based data exchange, facilitating underwater networks,…...
