[1st-mile-nm] IEEE: 5G is in Danger of Being Oversold

[Doug Orr]

I'm pretty sure mimo is going to be like multiprocessor compensating for
the demise of Moore's law in processors around transistor density:
applications have to change for it to be of profound use, it won't speed up
things to their advertised potential, except maybe a few new things come
out as the result of new end to end stacks...

Most of the speed hacks don't look like they will work well for anything
other than big parallel transfers, and latency is still speed of light
constrained. Anything involving the edge starts to eat power and comes with
troublesome consistency issues.

People picturing super fast web and 8k movies are likely in for some
surprises.

Self driving cars will need to be largely autonomous, so I find all of the
talk about how they are the 5g killer app confusing. That may just be my
ignorance. Wrt super chatty self driving cars, aggregate bandwidth is the
issue and there will be a lot of work carriers have to do to support cell
density at scale. Having your car stop working in a cell dead zone seems
like a bad consumer experience...

5g looks like the primary muddier of 5g waters to me.
