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.
A KAUST student blog post discusses optical wireless communications (OWC) as a solution to radio frequency exhaustion. OWC uses optical frequencies to carry electrical signals, offering advantages like high data rates and immunity to electromagnetic interference. Free-space optical (FSO) communication, a type of OWC, is applicable for inter-building connections and has seen use cases such as broadcasting during the 2010 FIFA World Cup. Why it matters: OWC research and deployment in the region can support high-bandwidth applications and provide cost-effective connectivity solutions, especially in challenging environments or disaster scenarios.
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.

Why it matters: This appointment positions the UAE as a leader in innovative telecommunications solutions and strengthens TII's role in shaping global telecommunications standards.
MIT Technology Review Arabia recognized two KAUST researchers in its annual Innovators Under 35 MENA Award. Yuxiang Liu developed Sun-Fi, an optical wireless communication network for smart cities that transmits data through window glass using modulated sunlight. Balsam Alkouz created a system for coordinating drone swarms to deliver supplies and deploy communications in disaster zones. Why it matters: The awards highlight KAUST's role in fostering innovative research aligned with Saudi Vision 2030 and developing cutting-edge technology for smart cities and crisis response.
KAUST, in collaboration with the Communications, Space and Technology Commission (CST) and Meta, has launched a Terragraph Wi-Fi project to bring high-speed internet to the Modern Architectural Contracting Company (MACC) camp near KAUST. The project utilizes Meta's Terragraph technology, a gigabit wireless system operating in the 57-71GHz band, to provide a low-cost, high-speed alternative to fiber. Weather stations will monitor climate variables affecting the hybrid RF/FSO links, validating KAUST's research in extreme bandwidth communication. Why it matters: This deployment demonstrates a practical solution for delivering affordable, high-speed internet access to underserved communities in the region, leveraging advanced wireless technologies and KAUST's research capabilities.
KAUST researchers are exploring thin-film device technologies using materials like printable organics and metal oxides for a greener Internet of Things (IoT). They propose wirelessly powered sensor nodes using energy harvesters to reduce reliance on batteries, which are costly and environmentally harmful. Large-area electronics, printed on flexible substrates, offer a more eco-friendly alternative to silicon-based technologies due to solution-based processing and lower production temperatures. Why it matters: This research contributes to a more sustainable and environmentally friendly IoT ecosystem, aligning with global efforts to reduce electronic waste and energy consumption.
