3G speeds are great here. Probably because I live in a metro area. There's tons of fiber uplink sites, cause I'm right between Baltimore and DC. In rural areas, there aren't that many fiber hubs, so running fiber backhauls is costly especially if the nearest fiber switching station is in a CO 20 or so miles away.

High-speed backhaul isn't limited to fiber.

One option is microwave. The technology there has increased throughput manifold over the last few years.

You don't need - generally speaking - the throughput of fiber in rural areas anyways.
 
What most of yall are failing to remember is that att has some of the fastest speeds compared to other providers.. Yes I admit that attar have voice problems with calls dropping.. But lately I haven't experienced any calls failing
