Make that the last half-mile. Don't want to congest the spectrum.

Sorry, spectrum is limited, and spread spectrum isn't less spectrum
consuming, it's more. It just lets you dodge whatever frequency is in
use at any moment. So high-speed wireless needs to be used for short
distance transmissions only. (Or for directional transmissions, if the
frequency is high enough, as in orbital communications. But you've got
to use directional antennas, and you still need to limit the power.
Means the greater the distance, the tighter a beam you need.)

It nearly is that simple, but if you don't limit transmission power you
can end up with a very undesirable situation. "The next day" needs to
be understood as hyperbole. But it wouldn't take long.
