Subsea Acoustic Wi-Fi: the underwater wireless networking technology for high data rate, reliable communication.
AquaSeNT is dedicated to delivering unsurpassed performance in underwater wireless communication. Starting with the best technology from wireless broadband, AquaSeNT redesigned it, and improved it, using breakthrough digital signal processing algorithms to meet the tougher demands of subsea applications. AquaSeNT’s patented OFDM technology is inherently insensitive to the underwater conditions that are known to disrupt acoustic signals and enables both point-to-point communication and large-scale, multi-node networks.
More Data. Faster.
AquaSeNT’s OFDM technology is the key to Subsea Acoustic Wi-Fi. Many individual carrier signals, each at a different frequency, deliver large data packets, providing the most efficient use of bandwidth. Data is bundled much more densely than traditional techniques, and this allows much higher effective data throughput. And because Acoustic Wi-Fi is inherently insensitive to echoes and reflected energy, it is not necessary to reduce data rates as conditions shift, as is typically done with single carrier systems.
AquaSeNT’s acoustic communication system employs the most advanced on-board processors available and delivers the most advanced subsea communication capability. But this computational power goes beyond communication: it creates a platform that supports a user-configured, large scale, flexible subsea asset monitoring architecture. With the optional SeaLinx networking solution, users can work with AquaSeNT to develop custom communication protocols for advanced monitoring, control, data harvesting, and multi-channel communication systems.
Higher data rates and robust data links, and networking, mean more opportunities to connect with subsea assets. Autonomous underwater vehicles play an important role today in subsea surveys and pipeline inspection, but hold the promise of performing field inspections, data harvesting, and potentially even some repair missions.
