Large-Scale Modeling And Cell-Edge Coverage For Future Hetnet Deployments

This paper evaluates the large-scale channel parameters and the cell-edge coverage for various LTE-WiFi based, heterogeneous networks. Real world urban databases are incorporated into two separate 3D ray tracing software tools, specifically designed for the characterization of both microwave and millimeter (mm)-wave radio links. The study is performed for both LTE-800MHz and LTE-2.6GHz macro-cell configurations whereas it demonstrates the coverage enhancement attained by deploying 802.11n/ac/ad micro-cell structures. The significance of this study lies on the radio planning aspects of future heterogeneous networks.
