Don't know for sure that it means two sets of towers.  Some (lots?) towers are venture projects and independently owned.  Companies lease space on the tower.  I'm also aware of a church that leases space for comm systems in its bell tower.

  Can someone explain to me why there isn't one backbone for cell service? Why does one carrier have more coverage than others? If they all cover a particular area does that mean there is a separate set of towers for each service provider in that area? If so wouldn't it be a lot more efficient to have one set that they all shared, sort of like the electric grid? Inquiring minds want to know.
