We're using fixed wireless. Advances in that technology have made high speed broadband feasible in areas with high wireless interference like LA. We believe wireless is the best path for what we're doing. It doesn't require interfacing with existing infrastructure anywhere but at the towers/APs, it deploys and redeploys quickly, and can provide competitive speeds and beyond.
More importantly, it gives us the freedom of building our own infrastructure, since access to public infrastructure is prohibitively expensive--by design, it seems.
