So many groups have made up their minds first, find facts to back them later. In a more straightforward article would want to see the models assumptions in detail. The article quotes Dish, whose role is typically to drive up the costs of mergers. Without Dish doing that for the purchase of Clearwire, there possibly could have been billions more for Sprint network expansion or lower prices.
I still think that the prices will be more in mind for Verizon and AT&t. Honestly to build out a maintain and expand the network of that caliber and size you need obviously more money from your revenue source which is consumers. So in these higher prices to build out the network and to maintain it it cost lots and lots and lots of money I do not see prices going lower. They would not be turning a profit they kept prices where they are.
