Is that they do not want to pay or is it that the big 3 carriers have bought up wide swaths of spectrum in the "auctions" from the FCC and are just holding them, not using them. This is the big problem, the FCC is far to lax with allowing the big wireless carriers to buy and hold spectrum for years (in some cases decades) never using it for anything just so no one else uses it either
