MWC25: Fujitsu Shares its AI-Driven 5G Strategy for Telcos

Fujitsu showcased its integrated approach to AI and telecommunications at MWC Barcelona 2025, highlighting its AI-RAN solution that optimises GPU server resources by combining Radio Access Network functions with artificial intelligence applications.

Carlos Cordero, CTO for Fujitsu Spain, explains his role within this involves connecting global research with customer needs.

“I do two things. One is to be in close contact with Fujitsu’s research and development (R&D) division across the world to understand what's going on in the five different key technology areas we work in. 

“I then try to match those development projects to customer understanding, while looking at what pain points our technology can solve.”

We spoke exclusively with Carlos about Fujitsu’s goals for the telco industry and how the company is using its latest technology to support operators.

The journey towards AI-RAN

At this year's event, Fujitsu emphasised two primary technology domains with connections to AI applications.

“We are focused on network and communications, with two different kinds of technologies: Photonic and Open RAN," he says. “Photonics is able to put a lot of data on fibre optic, which is something we are extremely good at.

“We have also been promoting Open RAN technology for some time now, as an early advocate, and we have a fantastic portfolio on the technology.”

Fujitsu's AI-RAN solution represents a significant development, using artificial intelligence to allocate resources on GPU servers more efficiently by integrating RAN functions with AI applications.

The company has also introduced Private 5G network solutions designed to address increasing connectivity demands from organisations implementing AI initiatives. These networks represent potential growth sectors for telecommunications providers and technology companies.

“Our Private 5G solution is quite new, but now the cost of these networks is going down, people can deploy Private 5G even in small businesses,” he says. “Beforehand the cost was very big, given the different bits needed to connect devices to the infrastructure.”

This cost reduction creates opportunities for telecommunications companies seeking returns on 5G investments while supporting the infrastructure needs of AI-driven transformation.

“There are two hot topics for telcos. One is to increase that return of investment with 5G networks and the other is to find new revenue streams,” Carlos says. “In both areas, Fujitsu is positioned to help our portfolio, including the management and operation of the network, which is also important to manage return of investment.”

Boosting 5G networks

Carlos views 5G as a fundamental advancement that enables AI applications across multiple sectors.

He says: “5G technology is extremely different compared with 4G and 3G - it really makes a difference from a technology point of view.

“Today with 5G Standalone, you may achieve things which were not possible with the previous generations. And that's an opportunity in many sectors.”

These capabilities extend into industries where AI is transforming processes, including manufacturing and healthcare.

“It may allow you to automatise a factory and make it really intelligent and autonomous, but it's not just about 5G technology - it’s about enabling automation,” Carlos explains. “It's a transformer on healthcare because again, it enables a hospital to do things which are not possible with 4G, 3G and so on.”

For both telecommunications companies and technology providers like Fujitsu, the transformative capabilities of 5G represent powerful market opportunities.

“For telcos, it's a clear opportunity, but it is also an opportunity for companies like us because it's basically technology on top of another technology and we are very good at that,” Carlos notes.

“I think telcos in Europe in particular are doing good enough compared with the rest of the world. There are maybe too many [telcos] in each country and that's a problem for them, so maybe moving forward we will see some kind of concentration in the future.”

While telecommunications infrastructure continues to develop, Carlos identifies that enterprise adoption of AI technologies is currently lacking.

“From a deployment point of view, telcos are doing their role in each country, but maybe the problem is businesses being slow to adopt the technology,” he says.

“AI is everywhere at MWC this year - telco companies and Fujitsu are showcasing a lot of AI, but there is nothing really disruptive yet.”
