Regarding 4G and HSPA+ my understanding was that some providers (I believe AT&T was one, called HSPA+ a 4G). That's why providers that had the true 4G started using "4G LTE". 5G seems like it's just improvement over 4G. It can use the same frequencies, but uses them more efficiently. The millimeter communication that made most wear a tinfoil hat probably won't be used much. I think maybe it will be useful in open places where there a lot of people like stadiums. I think most of improvement on 5G won't really be noticeable to average user.
