The advent of 6G wireless communication systems heralds a new era of connectivity, promising unprecedented data rates, ultra-low latency, and ubiquitous coverage. We have at the CTL lab @ KAUST various research projects aiming to investigate the integration of several emerging technologies such as Free Space Optics (FSO), High Altitude Platform Systems (HAPS), and Low Earth Orbit (LEO) mega constellations to enhance the performance and capabilities of 6G networks. By leveraging the unique characteristics of each technology, this study seeks to address the challenges of achieving high-speed, reliable, and secure wireless communication in diverse environments and scenarios. These research projects (mentored by postdocs in the CTL group) will employ a multi-faceted approach combining literature review, theoretical analysis, simulation studies, and sometimes experimental validation.
