LTE is a major change in the evolution of mobile network architectures from two key aspects. Firstly, LTE represents the final stage in the evolution from circuit/packet hybrid networks to a fully IP-based packet network, and secondly LTE also transitions from the legacy hierarchical network architecture to a flat and distributed architecture thanks to the incorporation of the RNC in the eNodeB.

This report examines how LTE networks are driving changes in the mobile backhaul whether fiber, microwave, copper, or satellite and also discusses the influence of HetNets on LTE backhaul design.

Although not a "backhaul" technology as such the report discusses fronthaul for those applications using RRH for CRAN-based LTE RAN architectures, since the technologies involved in fronthaul are closely allied to those used in backhaul.
