Sprint currently uses bundled T1 lines for backhaul. These work OK for a 3G network before the smartphone explosion. However, they are insufficient now.
Network Vision will correct the backhaul issue. Upgrading to fiber or microwave bridge to fiber in almost all instances.
In the interim though, Sprint is still upgrading T1's trying to improve performance somewhat. Even though Network Vision is under way.
