Authors: William Tärneberg, Gilles Callebaut and Liesbet Van der Perre What’s in a name? ‘The spoken newspaper’ is the term grandma1 used to call the news broadcasted on the radio. The curious name became a witness to how news media changed rapidly. In the same way, the term ‘Access Point (AP)’ literally becomes a somewhat … Continue reading 6G urging new networking concepts and terminology
We have now released the 29th episode of the podcast Wireless Future. It has the following abstract: The research towards 6G is intense and many new technology components are being proposed by academia and industry. In this episode, Erik G. Larsson and Emil Björnson identify the key selling points of six of these 6G technologies. … Continue reading Episode 29: Six 6G Technologies: The cases for and against 
Four years ago, I reviewed the book “The 5G Myth” by William Webb. The author described how the telecom industry was developing a 5G technology that addresses the wrong issues; for example, higher peak rates and other things that are barely needed and seldom reached in practice. Instead, he argued that a more consistent connectivity … Continue reading Is 5G a Failed Technology?
We have now released the 14th episode of the podcast Wireless Future, with the following abstract: In this episode, Emil Björnson and Erik G. Larsson answer questions from the listeners on the topics of distributed MIMO, THz communications, and non-orthogonal multiple access (NOMA). Some examples are: Is cell-free massive MIMO really a game-changer? What would … Continue reading Episode 14: Q/A on MIMO, NOMA, and THz Communications
A new EU-funded 6G initiative, the REINDEER project, joins forces from academia and industry to develop and build a new type of multi-antenna-based smart connectivity platform integral to future 6G systems. From Ericsson’s new site: The project’s name is derived from REsilient INteractive applications through hyper Diversity in Energy-Efficient RadioWeaves technology, and the development of “RadioWeaves” … Continue reading 6G Physical layer development: the race is on
The channel fading in traditional frequency bands (below 6 GHz) is often well described by the Rayleigh fading model, at least in non-line-of-sight scenarios. This model says that the channel coefficient between any transmit antenna and receive antenna is complex Gaussian distributed, so that its magnitude is Rayleigh distributed. If there are multiple antennas at … Continue reading Many Applications for Correlated Fading Models
Line-of-sight channels normally contain many propagation paths, whereof one is the direct path and the others are paths were the signals are scattered on different objects. The interaction between these paths lead to fading phenomena, which is often modeled statistically using Rician fading (sometimes written as Ricean fading). The main assumption is that the complex-valued … Continue reading Rician Fading – a Channel Model Often Misunderstood
