Industry Innovation

Turning academia theory into real-world connectivity

As a Radio Algorithms Developer at Ericsson, Nils Fredrikson works at the intersection of mathematics, software development, and radio engineering to help improve how mobile networks perform around the world. His work focuses on advanced signal processing and real-time radio algorithms that support faster, more reliable connectivity at massive scale. What surprised him most after joining Ericsson was discovering that the complex theories often explored in academia are actively being applied to solve real-world engineering challenges every day. Working alongside experienced engineers and global teams, Nils continues to explore new technologies while contributing to innovation that impacts billions of people worldwide.

Radio Algorithms Developer

If there is one thing I would like to convey, it is that here at Ericsson Radio, we actually tackle those amazingly complex problems that you see in academia. They are real, and they are happening every day at Ericsson. That is truly fascinating.

The work powering the world’s mobile networks

Michael Gebhardt

Senior Specialist RF Linearization Tech

Michael works on advanced radio technologies that help billions of people stay connected every day, often solving some of the most complex technical issues we face. His work spans signal processing, RF engineering, numerical optimization, and hardware development, helping improve the efficiency and performance of mobile networks at global scale. Over nearly two decades at Ericsson, Michael has collaborated with international engineering teams to solve highly specialized technical challenges while also exploring emerging areas like integrated sensing and communication for future 6G networks.

To pack a football stadium with people and everyone still has connectivity in their phones, that’s quite a challenge that is enabled by what we are doing. To answer bluntly, you don't 'see' the impact it has. It’s invisible. But there is no way to enable billions of people globally to surf the internet with their phones without the kind of work we do.

Empowering Employees

Growth driven by curiosity

As a Project Manager at Ericsson in Japan, Arisa Oki has built a career shaped by curiosity, adaptability, and continuous learning. After joining Ericsson without a technical background, she transitioned from engineering into project management while collaborating across global teams and large-scale 5G initiatives. For Arisa, one of the most valuable parts of working at Ericsson is the culture of openness, where employees are encouraged to speak up, explore new opportunities, and shape their own career paths. Working across international teams has also helped her grow professionally while contributing to technology that connects people and industries worldwide.

Arisa Oki

Project Manager

Each project involves different people and different types of work, so there are days when I’m handling completely different tasks at once. That variety is what makes this role so interesting and rewarding.
