Sometimes I work in a factory (full of metal everything) that's a metal plated building with no signal repeaters inside, basically a faraday cage. U can get enormous signal boost by just opening doors trough the wall. Most places inside the building report low signal with no usable internet connectivity, but some special spots provide enough signal to get few KB/s trough both ways. I was always impressed by the amount of work needed to push few KBs of data to cell tower trough such conditions, given a phone is able to establish and hold a connection. With WiFi there would be no hopes of even holding a connection between two points inside the building 30+ meters apart.

That's an unfair comparison to cellular though as cellular has its own licenced spectrum with nobody else able to interfere, high transmit power limits and potentially a friendlier frequency for the sort of waveguiding you're talking about.

That's why I find the smartsky comparison so interesting - because it's a completely level playing field.
