Impacts of Encryption Everywhere (any solution?)

Mark,

A couple of things, first that kind of utilization isn't feasible once
penetration rates in dense areas reach certain levels.  There's a reason
that NTT Docomo moved more than 70% of their data traffic to the 3.5 GHz
band and that reason is that there's not (nor will there be) enough
wireless spectrum to meet the needs of everyone with licensed space.  (That
same use case is why all the big North American providers are looking at
CBRS.) Further, 4G/5G is going to have trouble scaling to the kinds of
network demands going forward, again especially in dense areas.  While it's
certainly possible today to stream unicast video over LTE and will (for a
while) even more feasible over 5G the physics simply aren't with the
wireless world.

I'd say that your example of poor DSL performance isn't unique, it happens
in some spots in the US, but in general wired performance has much higher
individual and even higher aggregate capacities *when correctly deployed.  *I
doubt your hotel example is a poor deployment though, it's more likely that
the hotel owners are under paying for both the WAN connection and the WiFi
infrastructure.
