The rise in interest of D2D connectivity has brought with it a transformative period of innovation and strategic realignment involving a number of key stakeholders. As the boundaries between terrestrial and non-terrestrial networks become increasingly blurred, distinct deployment models are emerging, each presenting unique opportunities and challenges. Two primary approaches are being seen, leveraging mobile (IMT) and satellite (MSS) spectrum frequency bands respectively to deliver connectivity. This session will examine the pros and cons of these 2 approaches and the broader implications that they may have on global markets, business strategies, and the shifting roles of satellite operators and MNOs. It will explore whether the future lies in a unified approach or in the coexistence of multiple models designed to meet diverse demands, as well as how evolving competitive and collaborative dynamics among key players may influence the direction of this rapidly evolving ecosystem.

• What are the pros and cons of D2D deployment models using IMT and MSS spectrum frequencies respectively, and what challenges and opportunities does each offer?
• How could these differences influence their potential adoption across different markets? Are there specific market segments or use cases where one approach is better suited than the other?
• Are the objectives of providers using IMT and MSS technologies aligned, or do they differ significantly?

• What key factors in the end-user experience will determine the success or failure of various D2D business models and approaches? How crucial will elements such as cost, coverage, and quality of service be in shaping user adoption and satisfaction?
• Beyond smartphone connectivity, how can D2D services and business models evolve to address the needs of IoT devices, cars, and other connected technologies, and what industries stand to benefit the most from these advancements?

Regulating direct-to-device (D2D) services across Europe remains in its infancy. While individual member states are beginning to explore regulatory approaches tailored to their unique circumstances, efforts are also underway at the European level to prevent fragmentation and establish a coordinated framework. As part of this, the European Commission have asked the Radio Spectrum Policy Group (RSPG) to prepare an opinion on developing an EU-level policy approach to D2D, focusing on aspects such as national authorizations, current and anticipated use of potential frequency bands, technical considerations, and the necessity for regulatory coordination and harmonization across the EU. The final opinion is expected to be released in the weeks leading up to this event, and against this backdrop, this session will look both at this and also the work that is taking place more broadly across Europe to develop a cohesive European policy framework that supports innovation and equitable access in the D2D sector. What are the steps that need to be taken in order to deliver this and are we on the right path?

• What role should the EU play in developing technical standards to ensure interoperability between terrestrial and satellite networks in D2D communications?
• What is the appropriate balance between European-level coordination and member state autonomy in the licensing of D2D services?

Policymakers around the world are working to update regulatory frameworks and keep pace with the rapidly evolving D2D market. This session will explore the countries and regions at the forefront of these efforts, highlighting emerging trends, as well as the similarities and differences that are emerging in regional approaches. It will delve into balancing the need for international collaboration with the importance of addressing specific regional priorities, market conditions, and dynamics; exploring how stakeholders can work together to create a cohesive policy environment that fosters innovation, competition and sustainability. With WRC-27 on the horizon, discussions will also consider its critical role in shaping the D2D future by addressing key issues like spectrum allocation and coexistence between networks and services. What path is being taken by international, regional and national policymakers to navigate the regulatory complexities posed by D2D in order to maximise its potential and deliver a connected future for the benefit of all?

As D2D connectivity continues to gain traction, an increasing number of potential new use cases and scenarios are being proposed. A key factor in the success of these use cases and of the D2D sector as a whole will be delivering the financial sustainability of these services, ensuring affordability for end users while maintaining profitability. This panel will explore the potential evolution of D2D services and technologies, examining their integration within the current connectivity ecosystem and how this may evolve as we move beyond 5G and into the 6G era. It will examine the key use cases and applications that could shape the trajectory of D2D, and examine the monetisation strategies that could enable these. Discussions will also look at the economic and societal benefits that could be brought to rural, remote, and disaster-prone areas around the world (eg, through connecting the unconnected, disaster response, environmental monitoring), and ask the question how financial constraints can be tackled to deliver services at an affordable level given that these are often some of the poorest communities on Earth.

As Device-to-Device (D2D) communication continues to evolve, there is a growing consensus that alignment with 3GPP standards is essential for scaling up systems and services. Standardization helps reduce industrialization costs—including those of space-compatible chipsets—while providing manufacturers with a long-term perspective and encouraging investment. This session will look at the work that is done both within Europe and globally to ensure that D2D solutions are rolled out in a way that is incremental to allow for flexibility around future development roadmaps, but at the same time be built with scalability in mind from the outset. It will explore how D2D fits within the 3GPP framework, how the diverse needs of different vertical use cases are being considered as part of this the early design phase, and more broadly at how standards within the D2D ecosystem are starting to emerge.
