Something important that may be overlooked in the blog post is that for most bands you need licenses to transmit over the air. ISM bands are unlicensed but may come with other limitations (e.g., in some countries regulators require a listen-before-talk mechanism that is not always implemented in cellular stacks).
OP here. You would need some hardware components to run a 5G stack, starting from servers to software-defined radios. Another challenge may be linked to spectrum licenses, unless you transmit/receive in unlicensed bands.
Generally, papers are published in conference proceedings or journals. Just look it up on Google and you will find the publication it belongs to, with the date: Volume 40 Issue 1, January 2010

I'm having the same experience right away. In particular I hate seeing lots of posts in the news feed that come from pages I don't like, but as some of my friend comment and like them they just appear in the feed.

So I decided to stop checking FB very often
