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.
AIDRC researchers co-authored an accepted IEEE Vehicular Technology Magazine article on time reversal for 6G wireless communications. The article presents experimental results on the spatiotemporal focusing capability of time reversal across carrier frequencies. It examines requirements for efficient time reversal operation and synergies with technologies like reconfigurable intelligent surfaces. Why it matters: The research explores advancements in 6G wireless communication, with potential implications for coverage extension, sensing, and localization capabilities in the region.
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 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 Ph.D. student Qurrat-Ul-Ain Nadeem received a 2018 Marconi Society Paul Baran Young Scholar Award for her work in full-dimension (FD) massive multiple input multiple output (MIMO) transmission technology. Nadeem's research could more than double the average throughput performance of existing wireless communication systems through 3D beamforming. Her work establishes a link between the industry's vision for FD-MIMO and the theoretical study of 3-D beamforming. Why it matters: This award recognizes young researchers in Saudi Arabia and highlights KAUST's role in promoting science and technology in the region, especially for women in STEM.
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.
Researchers from the AI and Digital Science Research Center (AIDRC) won the Best Paper Award at the 2022 IEEE Global Communications Conference (GLOBECOM) for their paper "RSMA for Dual-Polarized Massive MIMO Networks: A SIC-Free Approach".
