The rational exuberance of 5G
I don&#x27;t buy this hype about so much demand and applications. Why ?<p>1. It won&#x27;t really reduce costs. Why? Because 3-5ghz 5G offer similar spectrum efficiency to current methods while on the other hand mmWave(20+ghz), which do offer tons of spectrum,  don&#x27;t penetrate building, and attenuate rapidly in air, so you&#x27;ll need more base stations.<p>2. Users have shown they aren&#x27;t willing to pay more wireless. And for most  things consumers do like VR and 360 video etc, wifi is fine and cheaper.<p>3.There are other good methods for the internet of things, and 5G is too late for that anyway.<p>So that leaves the realistic use cases as cars(but isn&#x27;t it too early? ). and maybe VR(although we&#x27;re very far from appealing VR services which users will pay $60+&#x2F;month for, and we probably need for wifi confined AR to be a thing first ).<p>And on top of that the question remains - could we improve 4G enough, without needing to deploy all new hardware?
