Power Over Wi-Fi (PoWiFi)

University at Buffalo and Northeastern University researchers are developing hardware and software to enable underwater telecommunications to catch up with over-the-air networks. This advancement could be a boon for search-and-rescue operations, tsunami detection, environmental monitoring and more. Sound waves used underwater are just no match for the radio waves used in over-the-air communications, but the researchers are putting smart software-defined radio technology to work in combination with underwater acoustic modems...
