KAUST researchers developed Aqua-Fi, a system for underwater wireless communication using lasers and off-the-shelf components. The system uses a Raspberry Pi as a modem to convert Wi-Fi signals to optical signals, enabling bi-directional communication. Using blue and green lasers, they achieved 2.11 megabits per second over 20 meters, compliant with IEEE 802.11 standards. Why it matters: This innovation could significantly improve underwater data transmission, benefiting applications such as environmental monitoring, underwater exploration, and communication with underwater devices.
KAUST Professor Boon Ooi, Nobel laureate Shuji Nakamura, and colleagues are collaborating on laser-based solid state lighting (SSL) and visible light communications (VLC). The team is using gallium nitride (GaN) to develop high-performance semiconductor laser devices, leveraging nanofabrication techniques at KAUST. They demonstrated that their laser-based VLC system is over 20 times faster than LED-based Li-Fi systems. Why it matters: This research could enable faster, more energy-efficient data transmission using visible light, with potential applications in both terrestrial and underwater communication.
KAUST researchers developed a hybrid wireless communication system for non-invasive monitoring of marine animals, consisting of a lightweight, flexible, Bluetooth-enabled tag that stores sensor data underwater. The tag syncs data to floating receivers when the animal surfaces, which then relays the data via GSM or drones. The system is a collaboration between the Red Sea Research Center and KAUST's electrical engineering department. Why it matters: This technology provides researchers with detailed, near real-time data about marine animals, overcoming the limitations of invasive and impractical traditional tagging methods.
The Autonomous Robotics Research Center (ARRC) is developing underwater communication systems, including a multimode modem prototype, and has filed three patents. One key technology is the Universal Underwater Software Defined Modem (UniSDM), which supports sound, magnetic induction, light, and radio waves. ARRC also developed a network management framework for automatic network slicing (ANS) of communication resources. Why it matters: These advancements are crucial for improving underwater exploration, industrial maintenance, and marine monitoring in the region, enabling more efficient and reliable communication for underwater robots.
KAUST researchers published a paper in Nature Electronics outlining communications infrastructure enhancements for 6G to provide global internet access and bridge the digital divide. They propose innovations like aerial access networks, intelligent spectrum management, and energy efficiency improvements. In a separate IEEE paper, KAUST and Missouri S&T researchers demonstrate approaches for improving network throughput using UAVs and balloons in areas lacking terrestrial infrastructure. Why it matters: The research addresses the UN's Sustainable Development Goal of universal internet access and aims to bring connectivity to underserved populations, enabling access to essential services and opportunities.
