Sprint chose an unusual strategy in its opposition to AT&T's proposed buyout of T-Mobile by offering a solution to AT&T's claimed spectrum crisis. An FCC filing (below) claimed AT&T could increase its network capacity 600 percent by 2015 simply by making better use of the network resources it has. Using its large resource of unused spectrum for 4G could improve capacity by 250 percent alone; introducing a mixed-size network with both large and small cells could boost it by 300 percent, Sprint argued.
