Jeffrey Andrews, associate professor in the Department of Electrical and Computer Engineering and director of the Wireless Networking and Communications Group at the University of Texas, will present the inaugural seminar in the Wireless Institute Leadership Seminar Series. He will be discussion the future of cellular networks.
Cellular telecommunication networks and innovative mobile devices have transformed society by allowing global communication anytime and anywhere. But these networks and devices have become victims of their own success, with demand for data traffic that is soaring more than 100 percent per year, or over 1000x in the next decade.
Faced with supporting this growth, the cellular industry is transitioning from comprehensively planned networks that focus on wide coverage to organically deployed networks that roll out capacity over time where it is needed. The industry is also diversifying equipment offerings with picocells and femtocells that support increasing data rates over shrinking coverage areas compared to traditional macrocells. As a result of this heterogeneity, the resulting networks are more irregular and have been less amenable to modeling, analysis, and design.
This talk describes the forces behind these trends and presents a new framework for understanding the heterogeneous cellular networks of the future. Modeling and analysis of system performance with multi-tier Poisson point processes yields insights that generally agree with actual field deployments and much more complex industry models, and suggest that 1000x improvements may well be within reach.
THERE WILL BE AN OPPORTUNITY TO MEET THE SPEAKER FOR COFFEE AND LIGHT SNACKS IMMEDIATELY BEFORE THE SEMINAR AT 10:30 A.M.
