Choosing the Backhaul for LTE

Source: TMCnet
The advent of LTE trials by major carriers globally leads us to question once again the choice of backhaul technology given the ever increasing bandwidth demands of the new base stations. LTE proponents are predicting bandwidth capabilities per base station in the range of 100 to 300 Mbps. This of course depends on the operator having adequate radio access spectrum to deliver this amount of bandwidth to the end user. In many instances due to limited access spectrum the available throughput will in fact be closer to the lower end of the scale. Nonetheless this represents a significant increase over the existing 3G base stations and will require new backhaul strategies in order to deliver cost effective networks.
