How did we do with 5G?
This talk will address how well 5G actually met the original goals set for it or the requirements identified for new applications that are just about to emerge. Development areas where big steps are needed for 5.5G and 6G are identified. The talk will also ponder some root causes for the 5G shortcomings and how could we avoid such problems in the development of future wireless systems.
