I live in Boston, where Google had a service called WebPass which was fiber with radio dishes for the last mile. They eventually gave up on our market, but two other radio fiber ISPs exist$. So Google isn't the necessarily the best competitor in that market.
$ Due to a wacky series of misunderstandings, both of these ISPs service my building now that Webpass is gone. They periodically send out sales reps who bring snacks and wine.
There was an existing company called WebPass that Google bought. As far as I can tell, they got rid of all the local sales and support in the dozens of cities they operated in (presumably to fold all that into their existing Google Fiber org). It was a total failure.
