Saltenna's underwater capabilities include true wireless, high bandwidth communications and sensing. Unlike optical, Plasmonic communications are stealthy and not blocked by physical obstacles or turbid/cloudy water. Unlike acoustics, they are high bandwidth, stealthy, and safe for human and marine life.

Saltenna is working on enabling users to cut the cord underwater, eliminating tethers and still having weather-independent duplex communications with divers, underwater vehicles, surface vehicles, sensors, and other fixed installations.
