Powerful collaborations, cutting-edge science, and curious minds coming together for a glimpse of the future.

Stay tuned as we look at the latest updates on some of the most promising technology projects.

Hello and welcome. I'm your host, Peter Ballant, from Technicon. Today, we take

another look at the Serena project. Our communication needs in the not so distant future will

dictate faster data speeds and much higher bandwidth than ever before. 5G is definitely a solution to deliver faster,

higher quality video and multimedia content services,

but there is still quite a bit of work to be done.

We will see new, smarter, and more efficient antennas

delivering these signals.

And this is where the Serena project comes in. Partners in

Serena are looking at using gallium nitride alongside traditional silicone to enable beam steering

antennas. Their goal is to develop an architecture, which is small and cost-efficient, with robust

thermal management schemes.

Today we speak with Christian Fager, a professor from Project Partner Chalmers University of Technology in Sweden.

Welcome, Christian.

Thank you.

Let's start at the beginning, the need for Serena.

And I will preface my first question by saying that Serena is about

active antennas for millimeter wave communications and sensor systems. This means that Serena is

contributing to building the infrastructure for 5G. But tell us a little bit about the need here.

I mean, how important is millimeter wave or very high

frequency for 5G communications? And why won't today's technology work for tomorrow's solutions?
