While working at a wireless deployment company I became (in)famous for pointing out that wire is the future of wireless.
Might not make sense, but if you have ever deployed or run large scale wireless networks (data, not cellular, though both are under the belt at this point) you'll understand. If you can run wire, run wire. If you can't figure out how you can. If that doesn't work, then go wireless, but be ready to accept it's limitations.
