Re: wasn't 5G about speed?
5G is about bringing a new generation of connected devices. I'm all in favour if it helps my devices plan their electricity consumption to happen mostly when power is cheap (sometimes £0.00) overnight.
But it's more than that. It's about industry developing that new generation of devices - and the intellectual property that falls out of that. Of course most of the first generation of 5G will be utter dross, but their patents will live on. That's why Trump is so keen to hold Europe and Asia back. Delay deployment, and you delay the development, leaving US companies more time to grab the lion's share of the IP.
