This 90-minute technical session explores the architectural shift from static, hardware-defined connectivity to a dynamic, software-centric ecosystem.  We examine how the "TechCo" model leverages 3GPP Releases 16, 17, and 18 to transform the network into a programmable interface, allowing external applications to request and trigger specific network behaviours on-demand. By analysing the critical interplay between exposure, management, and service layers, we look at the actual protocols required to safely open the 5G Service-Based Architecture (SBA) to third-party developers without compromising core integrity.  We explore how standardized frameworks like CAPIF and SEAL act as the essential middleware, abstracting 5G complexity into high-value functional blocks for vertical industries.  From ensuring secure northbound communication via the NEF to enabling "Network-as-Code" for industrial automation, this session provides a comprehensive blueprint for building a production-grade Network as a Platform (NaaP) that is scalable, interoperable, and ready for the global API economy.

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.

Indoor wireless connectivity has become a critical element of modern communications infrastructure, supporting enterprise digitisation, passenger connectivity, public safety, operational radio and mission-critical services across buildings, campuses, venues, transport hubs and enclosed environments. However, reliable indoor and enclosed-area coverage can be difficult to achieve. Building materials, complex layouts, tunnels, underground areas, multi-operator requirements, interference, capacity demand and operational resilience all influence the choice of radio solution. Distributed Antenna Systems (DAS) provide a proven approach for extending and managing radio coverage and capacity across complex environments. This overview course introduces the role of Indoor DAS (iDAS), how different DAS architectures are used, how they compare with alternatives such as small cells, repeaters, radiating cable and private networks, and what should be considered when scoping, procuring or evaluating a deployment. The course deliberately includes rail, transport and critical communications applications, including stations, depots, tunnels, TETRA/PMR environments, emergency services coverage, public mobile services, GSM-R/FRMCS migration context and future mission-critical broadband considerations.

Global Navigation Satellite Systems (GNSS), including GPS, Galileo, GLONASS and BeiDou, are widely used for navigation, tracking, fleet management, emergency service operations and timing. The increasing availability of low-cost GNSS jammers, together with more sophisticated spoofing techniques, creates an operational challenge for law enforcement and associated agencies. This one-day course gives participants a practical understanding of GNSS interference, how jamming and spoofing present in operational environments, and how suspected incidents should be recognised, recorded, escalated and investigated.
