For divers swimming hundreds of feet beneath the oceans surface, communication is a notorious challenge. Electromagnetic waves, used in surface communication networks almost exclusively, fade out over long ranges in salt water, meaning that sound waves need to be used for data transmission instead. The company has developed a new approach to underwater communication: allowing divers to create ultrasonic, subaquatic networks that passively share information like their location and air supply status. It allows you to be more alert about whats happening around you, explains Anders Brodin, the companys founder and managing director, in an interview with The Verge.
