Executive Summary

3GPP Long Term Evolution (LTE) is a significant evolutionary step for UMTS in terms of capacity and architecture. The peak data rate is improved to be at least 100/50Mbps in DownLink (DL)/UpLink (UL). It's expected that 80-90% traffic volume will be generated in indoor and hot-spot nomadic scenarios in future. In this paper, a stand-alone LTE based out-band backhaul is designed for urban area in NLOS environment, and the interference and compatibility issues relating to co-existence of LTE micro cell and co-located LTE out-band backhaul are investigated by a static system level simulator. Feasibility and recommendation of installing out-band backhaul are analyzed according to the simulation results.
