The backhaul transmission network is the most difficult segment of a cellular network to upgrade for mobile broadband. Backhaul cannot easily be scaled-up and therefore for mobile broadband the capacity bottleneck shifts from the radio link to the backhaul. This paper explores how cellular traffic switching can cut backhaul requirements while improving 2G/3G network flexibility.
