5G is driven both by the need for mobile operators to continuously strive to satisfy the growing and unquestionable demand for mobile data, and to support new use cases and services. Regulators and governments have been involved in establishing policies and approaches to award spectrum, so that new 5G services can be rolled out to consumers, enterprises, public sector and government agencies alike. Questions remain about how much more spectrum is needed for 5G but also for what spectrum is needed for 6G which is due for commercialization in the early 2030’s. When it comes to the question of spectrum however, there are many different views about how growth in data traffic impacts upon demand for radio spectrum. It is also evident that below 6 GHz there is very little spectrum remaining that can be re-farmed for mobile services and much of the focus for new spectrum for future mobile (6G) services is concentrated above 6 GHz.

This 90-minute session explores the ongoing evolution of the network. We look at how 5G Advanced (3GPP Releases 18, 19 and 20) enables the continuing transformation of the network into an increasingly resilient, flexible, and intelligent platform capable of supporting a much wider set of advanced consumer, and (especially) industrial use cases.  By exploring key features and concepts like Non-Terrestrial (Satellite) Networks, the AI-driven air interface, and enhanced positioning - and developments in both the architecture and protocols of the underlying system that bring a range of performance benefits – we will see how 5G Advanced can meet the rigorous demands of industrial automation and immersive eXtended Reality (XR). We then shift focus to the early research and architectural pillars of 6G, examining the leap toward "AI-Native" networks and Integrated Sensing and Communication (ISAC), where the network functions as both a data carrier and a radar-like sensor. From Terahertz (THz) frequencies to "zero-energy" IoT devices that harvest ambient power, this session provides an initial look at the emerging and potential technologies that are expected to fuse the digital and physical worlds into a single, ubiquitous ecosystem.
