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 24k+ subscribers, youtube.com/wirelessfuture

Wireless signals look different when observed near to versus far from the transmitter. The notions of near and far also depend on the physical size of the transmitter and receiver, as well as on the wavelength. In this episode, Erik G. Larsson and Emil Björnson discuss these fundamental phenomena and how they can be utilized when designing future communication systems. Concept such as near-field communications, finite-depth beamforming, mutual coupling, and new spatial multiplexing methods such as orbital angular momentum (OAM) are covered. To get more technical details, you can read the paper “A Primer on Near-Field Beamforming for Arrays and Reconfigurable Intelligent Surfaces” (https://arxiv.org/pdf/2110.06661.pdf).
