6G Wireless. It Will Work! Introducing The 6G Report
I'm Dave Burstein, with the microphone at right. I'm starting The 6G Report because the race is on. March, 2018, China's Minister Miao Wei asserted, "We will be first in 6G." We'll hear similar from other countries.
Problem: No one knows what 6G will be. (That doesn't stop the politicians.) A good working definition is "Important wireless advances that weren't ready for 5G."
6G, 5G, & 4G are nearly meaningless marketing terms. Wireless improvements are coming at a ferocious rate. As I write in 2018, "5G" networks are building and soon will be ready for customers. Many of them will be slower than some 4G networks that are incorporating the latest.
Tools for the next generation of wireless are working in labs around the world. Hundreds of papers have been written on Distributed MIMO/"Cell free" alone. Frequencies from 60 GHz to over 100 GHz are in lab trials. Dynamic sharing of spectrum now works, and can extend to all the licensed frequencies as well as the Wi-Fi bands.Getting closer to the truth is always my goal. Email me if I make a mistake or to share an opinion. I'll thank you. email@example.com

Gabriel Brown of Heavy Reading, a respected analyst, writes "Some of your 6G stuff (e.g. no-cell RAN, above 40GHz, shared spectrum, etc.) was supposed to be 5G. Whether that happens in practice, I’ll guess we’ll see in time. How and when the 5G to 6G threshold is crossed will be interesting." He's right, of course: None of what I'm calling "6G" is news to the best engineers in the industry, including many at 3GPP creating the 5G standard. It's always a tough call as to what is ready; there are also practical limits on complexity. Currently, 3GPP is using spectrum up to 54 GHz, although 60-77 GHz are actively being discussed. Sharing of unlicensed spectrum is central to Rel. 15; but there's an even bigger payoff in sharing some of the current monopoly spectrum.
