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 27k+ subscribers, youtube.com/wirelessfuture

New cellular network deployments are often associated with new frequency bands. 6G will likely use the upper mid-band from 7-24 GHz. It is called the “golden band” since it provides more spectrum than in current 5G networks and features decent propagation conditions. In this episode, Erik G. Larsson and Emil Björnson discuss the coexistence issues that must be overcome when operating in this band and how much spectrum we can expect to utilize. The future role of multi-antenna technology and its associated challenges are detailed, including the emerging “Gigantic MIMO” term. The prospects of exploiting near-field propagation effects in 6G and the road towards distributed cell-free MIMO are also covered. You can read Emil’s paper about Gigantic MIMO here: https://arxiv.org/pdf/2407.05630 Nokia has a white paper about coverage evaluation: https://onestore.nokia.com/asset/213702
