Mobile World Congress (MWC) 2026 arrives at a pivotal moment for the telecom and cloud industries. AI is moving from demos to core network infrastructure, 5G monetization remains under pressure and cloud-native architectures are no longer optional as we head into 6G.
Against that backdrop, this year’s show will test whether the industry is delivering measurable progress — or simply refining the narrative.
At MWC 2026, Fierce Network is focused on the themes that will shape operator strategy and vendor roadmaps over the next 12 months: AI-native networks, open RAN performance and scale, 5G standalone (SA), cloud convergence, edge AI deployments and the growing role of satellite connectivity.
The question isn’t what will be announced. It’s what will change carrier economics and enterprise adoption.
As executives, engineers and investors gather in Barcelona, we’re separating signal from noise — and tracking the trends that matter beyond the show floor.
AI moves from feature to infrastructure
We've already called dibs on one of the big buzzwords that we're expecting to hear a lot of the show: AI latency. What is AI latency? It's is the time delay between an input being sent to an AI system and the system producing a usable response or output.
Being raised as a journalist on late 90s telecom, I like to think of it as the speed of voice packets zooming from one caller to the other. I fully realize this probably seriously shows my age, but oh well, I'm a writer not an engineer so I tend think about things in easy terms so as to understand them better.
When it comes to AI, latency matters for telcos, hyperscalers and data center operators because the multitude of AI applications coming down the pike are going to require various levels of latency and network operators need to be prepared to deliver.
Some networks are inherently better at lower latency than others (like fiber, for example) but the problem is that no one knows for sure what AI latency requirements will look like. It's still too early.
Our friend Mike Dano over at Ookla wrote about AI latency for us — as did Steve Saunders, who interviewed the CEO of Cerebras last week. Plus, T-Mobile's new real-time AI translation service needs low latency to make its very interesting, innovative service work.
I'm calling, "BUZZWORD," and sensing it's going to be a big thing at Mobile World Congress and likely into the middle of the summer, at the very least.

Satellite and non-terrestrial networks
Satellite is rocking the telecom world, and we’ll be tracking all things satellite at MWC. Fortunately, the GSMA is hosting a high-profile panel on Monday, March 2, about satellite connectivity. And it’s scored a host of top names, including Gwynne Shotwell, President and COO of SpaceX; Michael Nicolls, SVP of Starlink; Allison Kirkby, chief executive of BT Group, and Mickey Mikitani, founder of Rakuten Group.
They’ll be discussing all the exciting trends around direct-to-device (D2D) satellite connectivity, which works with terrestrial wireless networks. And they’re bound to also touch on the big growth in satellite broadband, which is a sticky topic in the U.S., given all the BEAD awards that have been given to satellite operators.
Another hot satellite topic we’ll be tracking at MWC is the integration of satellite connectivity into IoT services, something that is suddenly making IoT seem interesting — like this Vodafone IoT story I wrote about last week.

AI moves out of the data center and into the network
AI has graduated from school and is now ready to go to work – in other words, AI is moving from training to inference. That means AI has to get out of the data center and go everywhere on the network.
Mobile World Congress is set to spotlight AI everywhere: CPU-driven AI infrastructure, real‑time edge intelligence and agentic systems reshaping how networks and devices operate. Expect major focus on 5G‑Advanced progressing toward 6G, with programmable networks enabled by Open Gateway APIs, plus a surge of momentum in satellite‑to‑device connectivity as pilots mature into commercial deployments. Overall, it’s a year where AI becomes deeply embedded across infrastructure, enterprise, and consumer tech and where CPUs, not just GPUs, take center stage in driving practical AI outcomes.

AI infrastructure meets telco
This year at MWC, I’ll be watching closely to see how the relationship between hyperscale cloud companies and telcos is evolving in the AI era.
Cloud companies have been coming to MWC for several years now, but those conversations were primarily around migrating assets to the cloud and how the cloud could enable new network capabilities. The message then was that telecoms needed the cloud and its efficiencies to move into the modern era. Now, it feels a little like the roles are reversed: hyperscalers need telecom operators to connect their growing network of data centers and deliver AI to the masses.
It'll be interesting to see what balance these companies strike between being competitors for AI revenue and partners who inherently need one another to be successful.

The monetization reality check for 5G
Ironically, where a few years ago, vendors were pitching their 5G hardware and software products, I think we’ll see a lot of talk about how operators need new solutions to get a return on their 5G investments and what they need to do to re-engineer things to be more efficient. Many operators are opposed to a whole new core in 6G, so it will be interesting to see how the vendors walk the line between what they want 6G to do and what their customers want from 6G.
In addition to the dance between vendors and carriers in 6G, I’ll be keeping an eye out for any acquisition news among vendors in the infrastructure space, as well as these areas: 5G-Advanced, digital twins, open RAN, virtual RAN, AI-RAN, satellite connectivity and 6G. And robots, lots of robots.

Prepping for 6G
AI-enabled mega antenna arrays, or Giga-MIMO as it is called will make a splash at MWC this year, as attendees chase technology that could be labelled "pre6G" - even though it will actually be used with 5G systems. ZTE has made the early running before the show. As Mobile Experts analyst Joe Madden has already told Fierce that all the main RAN vendors will all deliver a version of this architecture. The Giga-MIMO antennas will be able to deliver fast data comms on a macro scale.
At the other end of the 6G scale, We expects to see some 6G sensing demonstrations in very controlled indoor environments. These may use sub-terahertz frequencies to determine environmental changes like movement and location in a controlled situation.

Quantum shifts from theoretical to mitigation for telco
MWC 2026 will see the conversation about post-quantum readiness shift from the theoretical to what telcos can actually do to mitigate their networks from quantum computer attacks. Many telcos, such as Orange Business, have already announced they're doing work with quantum technology in some way, but the pressure is on for them to adopt Post-Quantum Cryptography before Q-Day, which could happen in the next several years.
Aside from post-quantum security applications, I predict there will be lots of discussion around how quantum can be used for 6G, data center edge applications and network sensing.

The real test will be execution
MWC 2026 will generate no shortage of announcements, partnerships and product claims. The real test will be execution. Can AI meaningfully reduce network operating costs? Will 5G standalone finally translate into durable enterprise revenue? And are cloud-native architectures delivering operational agility — or just complexity at scale?
Throughout the week, Fierce Network will be reporting from Barcelona, separating long-term shifts from short-term noise. As the industry pushes toward AI-native infrastructure and new monetization models, the conversations at MWC may signal whether telecom is entering its next growth cycle — or recalibrating expectations once again.
