The Wireless Networked Communications (WNC) series of underwater acoustic modems provide best-in class performance with up to 15 kbps and more than 4 km of communication range (horizontal) in littoral waters for the M25M series, and up to 30 kbps and over 1 km of communication range for the S60H series. Both are optimised for throughput, communication range, and reliability with features like spatial diversity combining, Machine Learning enabled adaptive link tuning, and robust forward error correction codes.
