Should be called HmmmmWave
I understand the fascination with speed for mobile communications.
Economic operators also understand the cost reality, because cell sizes shrink as the frequency increases (up to perhaps 200m on a good day). There is virtually no penetration of solid objects and you pretty much need line of sight. In order for base stations to deliver the achievable radio throughput, each base station needs fibre backhaul.
The hardware cost, backhaul cost and simple logistics of delivering many additional base stations will mean that, realistically, there won't be blanket mmWave cover except perhaps in top traffic city centre areas and possibly event venues.
So don't get too excited about top speed wireless comms for consumers yet.
Happy to be proven wrong.
