We are approaching a wireless future, where everything around us becomes connected and increasingly intelligent. Access to wireless connectivity is becoming as essential to our lives as access to electricity and water. In this podcast, two renowned Swedish academics discuss current and future wireless technology, as well as its impact on society. Erik G. Larsson is an IEEE Fellow and Professor at Linköping University, Sweden. Emil Björnson is an IEEE Fellow and Professor at the KTH Royal Institute of Technology, Sweden. They have written several textbooks, received numerous scientific awards, published hundreds of papers, and have tens of granted patents. They have a YouTube channel with 30k+ subscribers, youtube.com/wirelessfuture

  • 48. Non-Uniform Antenna Arrays and Movable Antennas
    Mar 28 2026

    Antenna arrays are used everywhere to enhance the wireless signal quality through beamforming and aperture gains. A common practice is to arrange antennas uniformly along a line or in a rectangle, but this is not necessarily the preferred arrangement. In this episode, Emil Björnson and Erik G. Larsson discuss how the geometry of an antenna array affects the shape of the beams it can transmit and the ability to spatially multiplex many users. They uncover how uniform arrays excel at packing many antennas into a compact space, while adjacent antennas collect redundant information about the world around us. In future systems operating above 6 GHz, we might not be able to afford to fill the aperture with antennas and can instead place them in a sparse non-uniform pattern. The vision is to optimize the arrangement at each base station site to maximize its communication and/or sensing performance. The conversation covers grating lobes, minimum redundancy arrays, preoptimized irregular arrays, and movable/fluid antenna systems.

  • 47. Everyone Talks About Integrated Sensing and Communications
    Feb 23 2026

    Almost every 6G-related keynote speech at scientific conferences focuses on ISAC: Integrated sensing and communications. In this episode, Erik G. Larsson and Emil Björnson discuss how sensing and communication technologies have been developed separately in the past but are built on similar yet distinctly different principles. The conversation covers different integration levels, beamforming implementations, fundamental tradeoffs, alternative waveforms, and the most important question: What would ISAC be used for if it becomes widely available in 6G networks?

  • 46. Are Reconfigurable Intelligent Surfaces Ready for the World?
    Jan 18 2026

    One of the first topics covered in this podcast was reconfigurable intelligent surfaces (RIS). Five years later, Erik G. Larsson and Emil Björnson return to this topic to reflect on what has happened since then. The conversation covers how these surfaces can improve wave propagation between transmitters and receivers, and identifies the most convincing practical use cases. Core challenges overcome in recent years are discussed, and Emil describes the RIS used in his lab and the lessons learned from his measurements. They also go through new forms of RIS, known as Beyond-Diagonal RIS, STAR-RIS, and Stacked Intelligent Metasurfaces. To learn more, you can read the paper “Reconfigurable Intelligent Surfaces in Upper Mid-Band 6G Networks: Gain or Pain?” (https://doi.org/10.1109/MWC.2025.3616979).
