Modelling
The first challenge, C0: Modelling, undertaken by Oxford University, focuses on developing a holistic model of connectivity that unifies both wired and wireless communication systems. The growing complexity of modern networks demands a more integrated approach to managing the entire spectrum of connectivity.
Traditionally, wired and wireless networks have been treated as separate entities, each optimized individually for specific use cases. However, with advancements in technologies such as terahertz (THz) communication, hollow-core fibres, and the expanding capabilities of both optical and radio frequency (RF) systems, a more unified model is essential.
This challenge addresses the need for a theoretical and practical framework that can accommodate the dynamic and diverse nature of these evolving technologies. By treating the wired and wireless spectrum as a single resource, Oxford’s work in modelling aims to optimize how different combinations of these channels can be used together across various applications and environments. For example, a holistic model would allow for the seamless switching between wired and wireless modes depending on the user’s location, the type of data being transmitted, and network congestion. In areas where fibre optic networks are dominant, the model could prioritize wired communication for high-bandwidth applications, while relying on wireless spectrum in locations where wired infrastructure is limited.
The ultimate goal is to develop a model that not only predicts but also helps optimize network performance in real time. This will be critical in environments such as smart cities, industrial IoT networks, or autonomous vehicle systems, where different parts of the spectrum need to be dynamically allocated depending on the demand and network conditions. Furthermore, Oxford’s work in modelling is crucial for ensuring that future networks are sustainable, energy-efficient, and scalable. As networks become more complex, the model must account for factors such as energy consumption, latency, and security, making sure that different technologies harmoniously coexist to meet the ever-growing needs of consumers, businesses, and industries.
By establishing a foundational understanding of how to jointly optimize wired and wireless connectivity, this challenge sets the stage for the other three challenges—Connectivity, Adaptivity, and Security—to build on. A robust model will enable the development of more resilient and adaptable communication systems, positioning the UK as a leader in the next generation of global communication infrastructure.
