Moving from Vision to Implementation at the 6G Global Summit 2026

The 6G Global Summit 2026 took place on 21 and 22 May as a hybrid event at the National Arts Centre in Ottawa and online. Held in cooperation with Innovation, Science and Economic Development Canada, this was the first time that the event had taken place in the Americas. It was also held alongside the Connecting Canada event, organised by the Canadian Telecommunications Association and GSMA at the same venue on 20 May.

As regular readers will know, much of the early discussion around 6G has focused on long-term visions, possible use cases, ambitious performance targets and promising research topics. The theme of this year’s summit reflected how the conversation is now changing. The focus was on moving from theoretical research towards early implementation planning, including national and regional strategies, global alignment, spectrum roadmaps, AI-native networks and the economic models needed to make 6G commercially sustainable.

The timing of the summit was important. In February 2026, ITU-R Working Party 5D completed the draft minimum technical performance requirements for IMT-2030, the ITU name for 6G. These requirements cover six usage scenarios: immersive communication, hyper-reliable and low-latency communication, massive communication, ubiquitous connectivity, artificial intelligence and communication, and integrated sensing and communication. The framework also places emphasis on sustainability, security, resilience, ubiquitous intelligence and connecting the unconnected.

Shortly after the summit, 3GPP agreed the timeline for Release 21, which will include the first normative 6G specifications. The 5G-Advanced and 6G work packages and Stage 1 requirements are expected to be approved in March 2027, followed by the Stage 2 architecture freeze in June 2028, the Stage 3 protocol freeze in December 2028 and the final ASN.1 and OpenAPI freeze in March 2029. This means that the industry is now moving from broad 6G visions towards the difficult process of deciding which capabilities should become part of the first commercial standard.

One of the important messages from the summit was the need for global alignment. Different countries and regions have developed their own 6G research programmes, industrial strategies, spectrum priorities and policy objectives. These initiatives are useful for encouraging innovation and investment, but they must eventually contribute to a globally compatible system.

The success of previous mobile generations has depended heavily on common standards, globally harmonised spectrum and equipment that can be produced at scale. Fragmented regional versions of 6G would increase costs, complicate roaming and reduce interoperability. Governments, regulators, operators, vendors, research organisations, ITU and 3GPP therefore need to maintain international cooperation, even where national priorities and industrial policies differ.

At the same time, global alignment does not mean that every region will deploy 6G in exactly the same way. Countries have different spectrum holdings, geography, population density, existing infrastructure and economic priorities. Some may initially focus on improving urban capacity, while others may place greater importance on rural coverage, industrial connectivity, satellite integration or national resilience. The challenge is to support these different deployment requirements within a common global framework.

AI-native networking was another major theme. AI is already being used in 4G and 5G networks for traffic prediction, fault detection, energy saving, network optimisation and automation. In 6G, the intention is to consider AI as part of the system design from the beginning rather than adding it later as a separate management function.

This includes both AI for the network and the network for AI. AI could help optimise radio resources, mobility, network configuration, energy consumption and service assurance. At the same time, 6G may need to support distributed AI applications operating across devices, edge platforms, networks and central clouds.

There are still many practical questions. AI models consume computing resources and energy. They require suitable data and must be managed, updated, protected and monitored. Operators will need to understand how decisions are made and how failures can be detected. AI should therefore be used where it delivers measurable technical or operational value, rather than being added to every function simply because it is available.

Spectrum was also central to the discussions. Although 6G is often associated with very high frequencies, future networks will continue to depend on a mixture of low-band, mid-band, upper mid-band and millimetre wave spectrum. Lower frequencies will remain important for coverage and indoor penetration, while existing and new mid-band spectrum will provide much of the balance between coverage and capacity.

One of the dedicated summit sessions considered whether the traditional model of identifying globally harmonised pioneer bands remains the best approach for 6G, or whether a more technology-neutral spectrum model may be required. This is an important question as regulators prepare for WRC-27 and examine possible future mobile bands alongside the continued evolution of 4G and 5G networks.

New spectrum alone will not create a successful 6G ecosystem. Suitable devices, radio equipment, antennas and deployment models must be available at an acceptable cost. Spectrum sharing, coexistence with incumbent users, licence conditions and realistic coverage characteristics will also influence whether a band can be deployed commercially.

The wider 6G technology discussion extends beyond the radio interface. Future networks are expected to bring together communications, computing, AI, positioning, sensing, cloud platforms, edge infrastructure and non-terrestrial networks. This creates opportunities for new services, but it also increases system complexity.

Integrated sensing and communication is a good example. Mobile infrastructure could potentially be used not only for communications but also to detect objects, movement and environmental changes. This could support applications in transport, industrial automation, robotics, public safety and digital twins. However, it also raises questions around privacy, security, accuracy, regulation and commercial responsibility.

Non-terrestrial networks will also be an important part of future connectivity, although this evolution has already started with 5G. Satellites, high-altitude platforms and terrestrial mobile networks could eventually operate as parts of a wider three-dimensional connectivity system. This could improve coverage across rural areas, oceans, transport routes and disaster zones, while also providing additional resilience when terrestrial infrastructure is unavailable.

Perhaps the most difficult question is how all these capabilities will be funded. Operators are still working to generate returns from investments in 5G, 5G Standalone, network slicing, edge computing and enterprise services. A 6G system that requires another large infrastructure investment without creating clear value will be difficult to justify.

The business case for 6G is unlikely to come from faster consumer broadband alone. Potential value may come from programmable connectivity, service guarantees, sensing information, precise positioning, distributed computing, AI services, industrial automation and deeper integration between terrestrial and non-terrestrial networks. The summit therefore placed significant emphasis on the economic models required to turn 6G from a technical ambition into a sustainable commercial reality.

There are many lessons that 6G can learn from 5G. Standards must not become overloaded with features that are expensive to implement and rarely deployed. Network architecture must remain manageable. Energy consumption must be considered from the beginning. Devices must be affordable, spectrum must be usable and new capabilities must solve real customer problems.

The 6G Global Summit 2026 showed that the industry is entering a more practical phase of the 6G journey. Research remains important, but the discussion is increasingly moving towards standards, spectrum, architecture, implementation, commercial value and international cooperation.

There is still a long way to go before commercial 6G networks appear. Nevertheless, decisions being made over the next few years will determine whether 6G becomes a practical evolution of the global mobile platform or an overly complicated collection of impressive research ideas.

I have brought together a selection of publicly available videos from the 6G Global Summit 2026 in the playlist embedded below. The presentations and panel discussions provide useful perspectives from policymakers, regulators, operators, vendors and researchers involved in shaping the next generation of mobile technology.
