KAUST, in collaboration with KSU and KFUPM, is working on a project initiated by the Saudi Communications, Space & Technology Commission (CST) to expand mobile communication coverage in remote areas of the Kingdom. The study explores utilizing the sub-700 MHz ultrahigh frequency (UHF) band, potentially reassigning it from television broadcast to mobile telecommunication networks. This band's long wavelength radio waves can travel further and penetrate obstacles more easily, reducing network infrastructure costs. Why it matters: This initiative could bridge the digital divide in Saudi Arabia by providing affordable mobile connectivity to underserved communities.
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.
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 researchers propose using tethered unmanned aerial vehicles (TUAVs) with cellphone antennas to address public concerns about EMF exposure from mobile networks. The TUAVs would receive signals, reducing users' uplink exposure and employing low power 'green antennas' that do not radiate EMF. A network of ground stations would provide power and broadband data links to the TUAVs. Why it matters: The system could allow the development of 6G mobile systems to continue while decreasing EMF exposure, and the team has already applied for a U.S. patent for their proposal, indicating significant commercial potential.
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.
