Speech Title: Towards Better Space Networking with LEO Satellite Constellations: Experiences and Solutions
Abstract: The emergence of Low-Earth Orbit satellite networks (LSNs), exemplified by initiatives like Starlink, has ushered in a new era of global connectivity through “Internet from Space.” By coordinating LEO satellites into constellations, LSNs offer unprecedented download capacity and low latency for a wide range of networked applications that would otherwise struggle to operate over conventional satellite networks. However, compared to state-of-the-art terrestrial networks, they still face critical challenges, including constrained uplink capacity, packet loss spikes caused by frequent satellite handovers, and disruptions from solar storms, to name but a few. In this talk, we will share our firsthand experiences using LSNs in remote wilderness regions and explore promising directions for improving their performance. These include adaptive control mechanisms for satellite reallocation, semantic communication powered by large language models (LLMs), enhanced resilience to space radiation, and coordination across satellites in different orbits to enable a unified space network.

Speech Title: Current trends, opportunities and challenges in Educational Technologies
Abstract: This talk will summarise recent trends and driving forces behind the advancement and adoption of educational technologies and new pedagogies in higher education. Such technologies include, but not limited to, Artificial Intelligence, Extended Reality (e.g. Augmented/Virtual Reality and the metaverse), and gamification. The non-technical issues that need to be addressed as a result of adopting and leveraging these technologies are even more worthy of discussion e.g. re-design of assessments, AI competencies for teachers and students, and the ethical issues in the use of AI software. Variations in the emphasis and applications of educational technologies between Western and Asian institutions will also be outlined.
