A backhaul network is used to connect base stations (known as NodeB in 3G terminology) to a radio network controller (RNC).
Connection costs for base stations comprise a significant part of provider's total expenses, so it is reasonable to reduce costs related to building and running of such networks, in particular by implementing new technologies.
