- AI is transforming networks from monitoring to active control
- Open RAN deployments are scaling with real-world performance
- Operators are focusing on 5G standalone monetization and enterprise applications
Mobile World Congress 2026 in Barcelona brought together telecom operators, cloud providers and vendors from around the world to showcase the latest innovations shaping the future of networks. From AI-native operations to early 6G research, Fierce Network has analyzed the announcements, demos and interviews to identify the trends that matter most to operators, vendors and industry analysts.
One of the clearest messages we took away from MWC 2026 is that AI is moving from monitoring networks to actively controlling them. Demonstrations from Ericsson and Nokia showed agentic AI managing RAN optimization, traffic routing and fault detection across multi-vendor environments.
Meanwhile, despite the disagreements on whether or not open RAN is alive or dead, open RAN deployments are beginning to scale, with vendors emphasizing reliability and real-world performance rather than just pilots.
Operators are also turning their attention to 5G standalone (SA) monetization, exploring enterprise applications, private networks and AI-driven solutions for robotics and industrial automation. Although 6G research is still in early stages, companies are experimenting with terahertz spectrum, network slicing and AI-optimized architectures, positioning themselves strategically for the next-generation network wave.
Finally, MWC 2026 highlighted the convergence of cloud, edge and satellite networks, as operators optimize latency and coverage for AI workloads and distributed IoT applications. The combination of AI, open RAN, 5G monetization and cloud-edge convergence signals that the telecom industry is entering a period of rapid operational transformation. Fierce Network will try to keep up!
Here are 6 takeaways for the telecom industry:
1. AI becomes the operating system for networks
At Mobile World Congress, the biggest shift I saw wasn’t about whether AI matters for telecom — that debate is over. What’s changed is how seriously the industry is talking about putting AI to work inside live networks.
Instead of flashy demos, AI-washing and future promises, operators and vendors focused on how AI is being embedded into core networks, RAN and operations to improve efficiency, resilience and automation. Case in point: Amdocs' shift to its aOS agentic AI platform that can be bolted on to traditional OSS. The vendor rolled that out ahead of the show and I spoke to Ilan Sade, division president for GenAI and data at Amdocs, on the last day of the show about aOS and about GenAI for telcos in general.

2. The agentic network
Following in the network vein, one trend that kept coming up was the agentic network — the notion that networks will function as coordinated systems of AI agents, making decisions based on intent rather than manual configuration. During a session about 6G that I moderated on Wednesday, Dr. Tong Wan of Huawei, widely considered to be the father of 5G, delivered a presentation on what he called the "Agentic Core." He said he imagined a future where the core of the network was an AI agent that could determine when to update itself and just make the changes itself without software subscriptions or vendors. This would be a huge disruption — however, we have a while before it could become reality.
T‑Mobile and others also described a path toward more autonomous, self‑optimizing networks — but the subtext was that it would only work if the underlying network architecture and data flows are ready for it. So far, they aren't.
Regarding that data, multiple companies we spoke to stressed that AI doesn’t need more data — it needs better, curated network data. Without that, automation and observability break down quickly.

3. AI-RAN and Nvidia grabbed headlines
AI was all the rage at MWC 2026 and that included AI RAN. I was struck but not surprised by how many telecom vendors included Nvidia in their press releases, whether they centered on new partnerships or resurrected old ones. There’s a reason people dubbed it “Nvidia World Congress.”

4. Satellite and NTN
Another big theme was non-terrestrial networks (NTN), which is a 3GPP way of saying “satellites and space.” SpaceX executives were there to talk about Starlink Mobile and all of the satellites they’ll be launching in preparation for the mid-2027 launch of their next-generation direct-to-cell (D2C) or direct-to-device (D2D) service.

The prospect of Elon Musk and SpaceX/Starlink taking over the terrestrial wireless industry was certainly a top issue. My prediction (not exactly going out on a limb here): Musk’s moves in wireless will continue to be a hotly debated topic for the foreseeable future.

5. The smell of 6G in the morning
The rainy, early spring weather of Barcelona brought the fresh scent of the forthcoming 6G specification into focus at MWC. Despite the fact that it is going to be around four years before the commercial arrival of 6G, operators and analysts were already talking about new spectrum that’s going to need to be allocated for the expected bandwidth-hungry specification. So far, many observers expect that the 4.5 GHz, 6 GHz and 7 GHz will need to be opened up for 6G.

6. Spectrum hunger
Another thing that was hammered home to me at MWC was that 6G — at least in the initial public macro specification — will be more spectrum-hungry than any 3GPP release so far. People at the show told me that 400 MHz would be needed to support the expected bands of 6G. That’s larger than the 200 MHz and below that 5G had required, which was larger than 4G and so on. There’s likely to be a lot of chatter going forward about the 400 MHz chunks needed to support 6G as the standard draws closer.
