Hey bubretti,
My source of information was from a RF engineer that is under contract with Sprint and provides installation and maintenance of Sprint's wireless and wire-line networks. I was informed that Sprint is aggressively planning the LTE builds in these areas and plans on building approx 1,200 sites to cover these areas starting early summer 2014. Site preparations have already begun. Areas would include eastern KY (Ashland area), Huntington/Charleston WV, Beckley etc..
In addition to my previous posts above this regarding problems activating a Sprint LTE aircard in Ntelos territory, Co-workers have complained of having the same issues in WV (Beckley) and VA (Roanoke). I was extremely pleased with the download and upload speeds in Sprint LTE, Southern Ohio. Can't wait to get this service!
