I forget about that sprint tower in the crane repair place, I was at the site south of Canterbury two weeks ago and the tower stuff hadn't been started the base station has been done since x-mas or earlier
With all the reinforced concrete/ metal framed walls and the metal sub-floor under the concrete and roof there is not much getting into the meaty part of the MOA hell, it's hard to get a signal in the back of a home-depot.
News to me. The legacy nokia cabinets are coming out. So if they are counting aws only / in building sites that have a normal site number ( tons and tons of them) I would belive that. 20k of those is not a stretch.
