Aquatic Sensor Network Technology LLC (AquaSeNT) is focused on developing innovative and comprehensive underwater wireless communication and networking solutions. The effort has been not on trying to take existing acoustic technology one step forward but instead to achieve a quantum leap by adopting the best technology available in terrestrial radio and Wi-Fi for underwater communication and networking - essentailly to create networks, placing higher order intelligence into equipment and multiple nodes that can connect, the way a cell phone connects point to point in a seamless manner for users. The firm has pioneered orthogonal frequency division multiplexing (OFDM) technology for subsea communication. Equipment including their technology has been used by NOAA and on porjects exmaning polar ice caps. Implemented in an acoustic modem, AquaSeNT's OFDM technology has the capacity to deliver more information using a narrower bandwidth than competing technologies. OFDM has also been shown to outperform other technologies in challenging acoustic environments. Going beyond point-to-point communication, the performance advantages of AquaSeNT's technology allow effective networking between many nodes that enables data transmission over a wide area and longer ranges. The firm has developed underwater "acoustic Wi-Fi" used for oceanography research and is examining how this technology could be applied to oil and gas operations.
