The word "bandwidth" has become synonymous with "data speed" since these are proportional when using cables. In this video, Emil Björnson (emilbjo@kth.se) explains why the situation is much different in wireless communications. There is no bandwidth shortage in 5G, but your speed is limited by the bandwidth efficiency (also known as spectral efficiency). If you want to know how to improve the bandwidth efficiency in 6G networks, check out the lecture "Evolving Mobile Broadband Connectivity Towards 6G" ([ Ссылка ]).
