4.5G deployments growing strongly worldwide
I am currently analyzing 4.5G (to a much lesser extent 5G) deployments country-by-country throughout the world. It has already become clear 4.5G is way ahead of any (mmWave) 5G almost everywhere. One gripe: many organizations talk about "5G" when they really mean 4.5G...Indeed it does look like mmWave 5G won't see much deployment until around 2023 or even later.

Re: Spectrum is still the question.
It's not a simple evolution, 5G will use all-new spectrum even in the low-band deployment.

Re: Spectrum is still the question.
While I can see from a marketing perspective why coming out with a band is important, the reality is these networks are a constant evolution. 

One solution would be to quietly upgrade these networks to 4.5G and simply wait to make a splash when 5G is fully ready. Would that be a good solution?

Re: Spectrum is still the question.
To be fair Sprint did say near gig as I recall. Ray did say could get close on T-Mobile with 50MHz but they only have 50MHz in certain parts of the country. This is all peak speed BS as well. Wonder how performance drops off On a real network?

Re: Spectrum is still the question.
60MHz and 3CCA using TDD LTE Config 1 (or 2) won't hit 1Gbps. And that's with 256QAM and 4x4 MIMO on all three component carriers.

Spectrum is still the question.
Spectrum is still the elephant in the room for 4.5G in the US. Operators need at 50-60MHz in a bonded channel for 3CA. AT&T, T-MOBILE and Verizon don't have the reserves to do that nationwide. They’ll have to use LAA unlicensed channels to do that and that hasn't even been approved yet. Sprint can do 3CA at 2.5GHz. Which means they need to deploy many more small cells to that support that. Carriers and vendors are making it sound like ”gigabit LTE" is a done deal and that's just not the case.
