I don't really want to work for that kind of company any more, but it makes for entertaining tales later on in life.
It's one thing to use a competitor's product to demo your _equivalent_ product, but to somehow imply that your product is a step forward (smaller, lower power, faster, cheaper, etc) is quite different and even if you manage it in some form could still be grounds for calling it fraud.
5G next year simply isn't going to be relevant to most people. It will start as a gimmick, and then a few years later it will start getting interesting, and soon after that it will be everywhere and we'll all be loving it.
I think the questions remain around non-stop skin absorption once we blanket the population with it.
There is something really really big happening there, since "your communication costs" have been inflated to the max by the telco's for years. This new concept of provider independent network usage will kill a lot of providers that have grown by overcharging their customers with a jungle of plans and costs.
Maybe T-Mobile America will roll out 5G a few years earlier than my T-mobile but I bet it will still be worse than what I have today. Don't be fooled by fancy words. Less marketing more cell towers.
Was it bad planning to demo 5G without adequate spectrum - yes. Does it tell you anything about how well 5G will work when deployed in a real system - no.
For sure, 5G is overhyped but if you have spectrum (big if) and if you are willing to pay the costs to deploy 5G (another big if) it is technically capable of excellent performance.
However, the FCC will be auctioning 39 GHz in the near future. When that happens, the band will be restructured.
BTW, the 28 GHz band is currently being auctioned. 850 MHz in that band.
