It pretty much does not. Divers use one of two systems for comms, a tether to the surface, or acoustic wave based communication equipment. Underwater drones usually use a tether for control.
Well I have a small generic GoPro like camera that has a wireless feature. The 2.4 GHz wifi propagates very poorly on it. Lose signal under an inch of water.
@adventurecruiser Yeah. The answer to that question is that it doesn’t. Only extremely low frequencies like MF propagate. Anything higher gets absorbed basically immediately. Submarines sometimes use MF. No handheld would be able to pack enough power or a long enough antenna to be useful. The main thing about a radio like yours is that you could have it when you resurface. In an emergency or somethin.
I would be very curious to see how RF propagates underwater
Me too, any idea how a test could be structured?
