Saltenna Releases Paper on Cable-Free Radio Links for Subsea Sensors, Vehicles

Saltenna has published peer-reviewed field results in IEEE Xplore. Its Plasmonix technology launches radio-frequency surface plasmon waves that travel along interfaces rather than straight through the water. In three underwater test scenarios, communication reached distances many times the predicted bulk range, even after accounting for ohmic absorption and spherical spreading.

The paper was presented at IEEE UComms 2026 in Sestri Levante, Italy, and added to IEEE Xplore on Oct. 15. It also lays out follow-on experiments to pin down where the method beats acoustic and optical links.
