48. Non-Uniform Antenna Arrays and Movable Antennas
In this episode Emil Björnsson and Eric Larson discuss antenna arrays, focusing on the shift from uniform, half‑wavelength spaced grids to more flexible, non‑uniform designs for future massive MIMO and 6G systems. They explain how massive MIMO works—using many more antennas than simultaneous data streams to form narrow, directed beams—and the role of channel state information obtained via reciprocity in TDD systems. The conversation then explores why simply adding more antennas isn’t sustainable, highlighting trade‑offs in link budget, regulatory limits, and mutual coupling, and introduces the idea of "antenna intelligence" to achieve similar performance with fewer elements by optimizing array topology.
47. Everyone Talks About Integrated Sensing and Communications
In this episode of Wireless Future, Erik Larsson and Emil Björnsson explore Integrated Sensing and Communications (ISAC) as a key pillar of 6G. They define ISAC as the fusion of radar‑type environmental sensing with traditional cellular communication, outlining four integration...
