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 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.
KAUST researchers have developed a new mathematical approach using stochastic geometry to mitigate 5G interference with aircraft radio altimeters. The solution defines ideal exclusion zone shapes around runways to protect aircraft while maximizing 5G performance. Triangular exclusion zones preserve altimeter signals while minimizing the area of lost 5G performance. Why it matters: This research provides a data-driven framework for regulators to balance 5G deployment with aviation safety, addressing a growing concern.
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, 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.
