Optical Wi-Fi allows for ultrafast underwater communications

EPFL spin-off Hydromea has developed a miniature optical modem that can operate down to 6,000 meters below the ocean's surface. It is sensitive enough to collect data at very high speeds from sources more than 50 meters away.

Radio

Radio is the transmission of signals by modulation of electromagnetic waves with frequencies below those of visible light. Electromagnetic radiation travels by means of oscillating electromagnetic fields that pass through the air and the vacuum of space. Information is carried by systematically changing (modulating) some property of the radiated waves, such as amplitude, frequency, or phase. When radio waves pass an electrical conductor, the oscillating fields induce an alternating current in the conductor. This can be detected and transformed into sound or other signals that carry information.
