Sounds like you're talking about WiMax. I was briefly on WiMax in Bellevue, WA, but the service sucked, not sure if it was the tech itself or their infrastructure...
WiMax was the (pre)4G implementation using the old Nextel spectrum (a major reason why Sprint was an investor).
I had the EVO 4G on WiMax, had amazing speed, especially near the highways before anybody else did. Also made for a great hand warmer.
The point is that 5g may provide the product that most people want when they want fiber; have less additional infrastructure cost, and the wireless penetration doesn't matter if we consider a base station -- or a physical install (as required by fiber or coax)
