Mobile World Congress MWC 2026 – Event Recap
From satellite voice calls to AI-native networks, MWC 2026 made the case that connected vehicle infrastructure is changing fast
Mobile World Congress returned to Barcelona’s Fira Gran Via, and this year’s theme was less about raw hardware and more about what the industry will do with the intelligence it has been accumulating. In the run-up to the show we said the IQ Era – AI-native networks, intelligent infrastructure, non-terrestrial networks, and autonomous systems – is our core business, and MWC 2026 largely proved that right.
Across the four days, conversations on the show floor and on stage kept returning to the same set of pressures: the maturation of 5G and the move towards standalone cores, the gathering pace of 6G standardisation and research, the integration of satellite into mainstream mobile infrastructure, and – running through all of it – artificial intelligence reshaping what networks are actually expected to deliver.
For Cubic3, it was one of the more consequential MWCs in recent memory. We arrived with two major announcements, took part in three panel sessions with some of the industry’s leading names, and came away with a clearer picture of where vehicle connectivity is heading. Here is how the week unfolded.
MWC 2026 The Show in Brief
The 2026 edition felt like a coming-of-age moment for non-terrestrial networks. Satellite connectivity, long treated as a niche add-on for extreme edge cases, appeared throughout the halls as a mainstream infrastructure conversation. SpaceX drew significant attention with the Starlink Mobile announcement, while Skylo argued that satellites should behave like just another cell site within existing roaming relationships, not a parallel, proprietary network – an argument that resonated strongly with what we have been building.
On the 5G side, Ericsson used the show to talk up the 5G standalone core as the commercial foundation for future monetisation, and Huawei launched a suite of U6GHz solutions intended to bridge the gap between 5G-Advanced and 6G. ETSI confirmed that 6G specifications are not expected before 2029, but that did not stop Qualcomm from demonstrating live 6G applications on the show floor.
AI was, as expected, everywhere. T-Mobile’s CTO argued that physical AI requires a new type of compute token and that operators are in a strong position to distribute it. Google Cloud pushed its telco autonomy roadmap – networks that identify and fix their own problems without human intervention. MediaTek’s ‘AI for Life’ keynote on the Wednesday drew a large audience. Whether you agreed with every claim or not, the direction of travel was consistent: the network itself is becoming an AI-native system.
What Cubic3 brought to Barcelona
The world’s first satellite voice call for connected vehicles
In partnership with Viasat and Qualcomm, with support from Fraunhofer IIS, Cubic3 demonstrated the world’s first live, real-time satellite voice call for connected vehicles over a 3GPP-compliant non-terrestrial network.
The significance of this goes beyond a technology proof-of-concept. Voice communication over satellite – not just messaging or location data – opens up emergency connectivity for drivers operating beyond cellular coverage, giving OEMs a way to maintain voice services in genuinely remote areas and address global deployment, liability, and driver safety requirements. Because it runs within a 3GPP-compliant NTN framework, it does not require proprietary hardware or a separate network subscription. It fits into the architecture that the automotive and mobile industries are already building around.
One SIM for everywhere: the Cubic3 and Skylo automotive connectivity solution
The second announcement was the culmination of work that started when Cubic3 and Skylo first announced their partnership in December 2024. At MWC, we unveiled what we are calling the world’s first automotive-grade connectivity solution that combines cellular and satellite networks through a single SIM, validated for commercial deployment.
The practical implication is that OEMs no longer need to manage separate hardware stacks or separate network agreements for terrestrial and non-terrestrial coverage. A vehicle running on this solution switches between cellular and satellite automatically, maintaining reliable connectivity in regions where mobile network coverage is thin or absent. It supports emergency voice services, safety-critical fallback, and the kind of always-on connected services that global vehicle programmes depend on. For software-defined vehicles, it offers a path to consistent, policy-driven connectivity that can keep up with the intelligence moving into the car.
Where we spoke at MWC 2026
Monday 2 March – GSMA Smart Mobility Roundtable
André Schlufter, our Director of Automotive Connectivity Innovation, joined the GSMA’s Smart Mobility Roundtable to discuss what connectivity can and cannot do today, the 5G opportunities companies are moving to act on, and how AI is changing what mobile networks need to deliver for connected vehicles.
Tuesday 3 March – Snowflake: Connected Intelligence
Steven Cochrane, our VP of Data and AI, joined Snowflake’s panel on building intelligent infrastructure for the AI era. The discussion examined how data architecture needs to change as networks generate more real-time information and as AI workloads move closer to the edge, with a particular focus on how you manage, store, and act on the data a modern car generates at scale.
Wednesday 4 March – GSMA Smart Mobility Summit: Built for Tomorrow
André returned to the stage for a second GSMA session on how 5G, cloud-native platforms, and real-time connectivity are enabling autonomous vehicles to make faster decisions. The session covered advanced use cases across public and private networks, adaptive traffic systems, teleoperation, connected ports, and digital aviation corridors. It was a useful reminder that the connected vehicle conversation is no longer confined to the car itself.
The 3 Key Takeaways from MWC 2026
Three things stood out across the week.
- The first was that satellite connectivity has crossed from ‘emerging’ into ‘infrastructure’. More operators, OEMs, and platform providers are treating NTN as a core part of their network architecture, not a contingency. The standardisation work happening through 3GPP is making that possible.
- The second was that the industry’s patience with fragmented connectivity solutions is running low. Whether we were talking to automakers, network operators, or enterprise customers, the same frustration came up: managing separate contracts, hardware, and SIMs for different coverage scenarios is not sustainable at scale. A single, unified solution that handles both terrestrial and non-terrestrial coverage is rapidly becoming a commercial requirement.
- The third was that AI is no longer an addition to network strategy; it is reshaping what the network is for. The conversations at MWC 2026 were not about AI as a product feature. They were about AI as the reason the network needs to be faster, more autonomous, and more capable of acting on data in real time – including at the edge and inside the vehicle.
On Track for Seamless Vehicle Connectivy
For Cubic3, all three of those trends point in the same direction. We left Barcelona with two live demonstrations behind us, three major panel contributions on the record, and a clearer sense that the industry is moving towards the kind of seamless, always-on vehicle connectivity we have been building for.
