Re: Not new
5g mmwave - limited distance. 5g sub-6GHz - can reuse exactly the same 4G bands and exactly the same range. It can use additional frequencies nearby with comparable range.
If you go to a 5G coverage area on the motorway, it is most certainly not mmwave, and certainly does not only last a few metres.
In crowded areas with heavy footfall, mmwave gives the capacity that the “traditional” bands cannot in practice (the laws of physics are rejecting requests for amendment).
I actually use 5G and the transition down to 4G is noticeable and a worse experience. It is down to network deployments of course, and yes, with 5G too, there will be the NIMBYs and what about my backyard-ers, but for the vast majority it is a better way for a web browser user, the zoom user and a 4K video junkie to coexist on cellular.
