Heterogeneous Networks - A New Paradigm for Improving Cellular Capacity

Dr. Avneesh Agrawal

About the talk:
Embedding pico/femto base-stations and relay nodes in a macro-cellular network appears to be one of the most promising techniques for achieving substantial gains in system capacity per unit area as well as cell-edge user throughput in wireless cellular communication systems. Networks with co-channel deployment of different types of base stations are referred to as heterogeneous networks. Introduction of these highly disparate base-station types on the same wireless channel challenges some of the established paradigms in cellular system design, and necessitates advanced interference coordination along with other novel optimization techniques to realize the full potential of such a heterogeneous cellular infrastructure. This talk highlights some of the problems that need to be solved in order to maximize the capacity and cell-edge performance of heterogeneous cellular networks, and highlights a few promising approaches that could be developed further, in order to address these problems in an effective manner.
