On that point, have you looked at Myriota's research? (https://myriota.com/) In developing their system they went right back to the fundamentals and reworked everything around the idea of short messages. For example, an implicit assumption in the Shannon bound is that the message length is long, so they figured out that their short message system doesn't obey the Shannon bound and designed the coding and so on accordingly. It's fascinating stuff if you're into information theory.
