Underwater WiFi developed using LEDs and lasers

Underwater communication is possible with radio, acoustic and visible light signals. However, radio can only carry data over short distances, while acoustic signals support long distances. Now a new underwater wireless system is introduced, Aqua-Fi, that supports internet services, such as sending multimedia messages using either LEDs or lasers. LEDs provide a low-energy option for short-distance communication, while lasers can carry data further, but need more power.
