No, but cables can be duplicated, wireless bandwidth can't.

lasers are wireless and don't compete for spectrum. beam-forming with phased arrays is not quite as good, but still gives you more capacity than naively shared spectrum would.

This is laser based? Are the building ground stations everywhere too?

The links to end-users use beam-steered microwaves, sat-sat links use laser.

I was more making a more general statement: that wireless is not necessarily synonymous with shared medium.
