The halls of the GSMA’s Mobile World Congress in Barcelona were less crowded this year. Last-minute cancellations, particularly from participants in or transiting through the Middle East amid armed conflict, were a somber reminder that we are navigating a turbulent time. Our thoughts are with those affected.

Even so, the communications ecosystem showed up with energy and resolve. As the world grapples with geopolitical instability, the telecom industry continues to face its own turbulence. Among the changes: US operators were more visible—a positive signal, perhaps, of industry coordination to ensure that the telecom industry maintains its relevance within the broader technology ecosystem. 

Several themes stood out.

Near-term priorities for operators

AI isn’t another G-cycle but a structural reset for telecom operators. Operators show broad diversity in approaches, some driven by geographic realities and others by strategic choices. These include sovereign digital infrastructure (France’s Orange); AI-powered customer experience (South Korea’s LG U+); cloud-native, software-driven architecture (Japan’s Rakuten Mobile); and operational efficiency (Argentina’s Telecom Personal). Most activity focuses on reducing operating expenses and improving customer satisfaction. As leaders move from experimentation to deployment at scale, the performance gap with laggards widens. Any operator who doesn’t feel confident about the quantifiable business value they will capture over the next few years should revisit their roadmap. Boards and investors are expecting demonstrable results—quickly.

Quality, sovereignty, resilience, and provenance are now top priorities. The conversation is moving beyond speed to integrity and reliability of service. Low latency, jitter control, redundancy, and operational sovereignty are no longer technical specifications—they’re strategic differentiators. Operators also have a need and opportunity to act as trusted advisers, raising real-time alerts when fake content is suspected.

Autonomous networks and operations remain a hot topic. Even as operators work through technology and operating model transformations, the promise of efficiency gains and new value streams continues to attract attention. Leading operators filter what is technologically possible through the lens of what truly moves the business to get to a prioritized, pragmatic roadmap. They insist that their business and technology leaders, as well as suppliers, redesign end-to-end business processes before defining their architectural approach to autonomy.

Satellite service providers add another layer. Compared with previous years, satellite service providers were more prominent, with many marketing their direct-to-device (D2D) capabilities. As with fixed wireless access (FWA), reach and capacity still limit satellite connectivity as a substitute for terrestrial networks. However, it’s clear that satellite adds a layer to the communications ecosystem, and telecom operators want partnerships to offer D2D connectivity as a complementary service.

Preparing for post-quantum cryptography. Although we’re a few years away from production-grade quantum computing, preparing for its security implications should be on every executive’s agenda. Some post-quantum cryptographic approaches, such as lattice-based ones, are already being deployed. Transitioning infrastructure, networks, and devices to quantum-safe encryption is achievable, but it requires thorough reviews of systems. Without diligence, we could face crippling vulnerabilities in the not-too-distant future.

Debates shaping the next three to five years

How will AI transform telecoms? Most discussion of AI focused on how it can help telcos run better—cost savings, customer loyalty, incremental revenue opportunities. But AI will also change the network. It won’t just consume bandwidth but will also reshape traffic patterns (greater upstream traffic) while demanding ultra-low latency, edge proximity, resilience, and AI data centers. Operators have a narrow window to become core to AI infrastructure, rather than just capacity providers.

Opportunity in sovereign digital infrastructure? While some booths displayed banners promoting sovereign cloud, there was a notable absence of relevant stakeholders, including investors and operators of fixed infrastructure and data centers. Without them, dialogue around building the full digital infrastructure is somewhat limited. But the opportunity for the industry is big, and telcos have captured only a fraction to date.

More embedded intelligence in networks? Operators want to provide features such as voice translation services and deepfake video detection. But this could cause more friction with smartphone giants Google and Apple, who see these services embedded in their devices and mobile operating systems.

Smart glasses: niche or mainstream? The issues holding back smart glasses from broader mainstream adoption are well known: affordability; the need to be tethered to smartphones for adequate battery life and computing power; and the lack of a killer application. Many operators are worried that these issues will not be addressed quickly enough to generate the hoped-for wave of new connections and revenue that comes when consumers discover a new "must-have" device.

Specialized vs. standard silicon? Network equipment manufacturers are pursuing different strategies regarding whether to go with specialized or standard semiconductors in the network, and they also differ on the value of embedding AI inference capabilities in the radio access network (RAN). Telcos have differing views about the opportunities at the network’s edge and where specifically these opportunities will materialize. Some believe that the opportunities will be greater on devices and in smaller, private networks than for base station and central office opportunities. Operators’ ability to capitalize on revenue associated with physical AI is expected to be an early test case.

Whither 6G? Everyone agrees that reduced power consumption, better embedded security, and increased privacy and trust are necessary. However, after the struggle to generate returns on the massive investments in 5G, operators are deeply uneasy about rushing into the next transition.

This year’s Mobile World Congress made one thing clear: The industry is navigating a spectrum of turbulence, facing not one but many strategic decisions that may prove existential for many participants. AI, autonomy, sovereignty, satellite integration, and post-quantum security are not parallel conversations; they are converging forces reshaping the industry’s economic and strategic foundations. Winners will be those that scale beyond pilots to execution, prioritizing initiatives that deliver real value while building the resilience and trust that the digital ecosystem of the future demands.
