WNCG Profs. François Baccelli, Jeff Andrews and Robert Heath were recently awarded a $1,000,000 research grant from the National Science Foundation for research on Millimeter Wave (mmW) cellular networks. The project is entitled "Fundamental Properties of Millimeter Wave Networks: Signal, Interference, and Connectivity” and will develop new mathematical and analysis tools to uncover the potential of mmW cellular networks.
Since 2008, mobile traffic across the globe has increased at a rate of roughly 100 percent per year, while the available bandwidth, or spectrum, for data use has remained largely unchanged. During peak hours, wireless networks in major cities often reach a point of failure. With the explosion in online video traffic, which is predicted to occupy 66 percent of mobile traffic by 2017, industry, academia and government are searching for the future of mobile networks. The solution? To push beyond 4G networks and bring 5G to life and to consumers.
As mobile wireless communications progress, the Federal Communications Commission (FCC) is exploring technologies that could lead to the emergence of a new generation of millimeter wave (mmWave) wireless spectrum by the year 2020. Before mmWave carrier frequencies can be applied to cellular networks, spectrum allocations and regulatory frameworks must be determined.
Prof. Jeff Andrews of the Department of Electrical and Computer Engineering at The University of Texas at Austin wrote a piece for the IEEE Communications Society on whether or not densification will be the death of 5G. Prof. Andrews is the The Cullen Trust for Higher Education Endowed Professor in Engineering and a member of the Wireless Networking and Communications Group (WNCG). Over the last decade he has been one of the leaders in the effort to apply statistical theory to network capacity calculation.
A vast majority of the increased mobile data throughput has been enabled by ever-increasing densification, i.e. adding more base stations and access points that have a wired backhaul connection. This trend is set to continue for the next decade at least, primarily through the provisioning of small cells such as pico and femtocells. What if we reached a point where adding more infrastructure did not allow increased wireless network throughput? This would be comparable to the impending end of "Moore's Law"; a cataclysmic event having far-reaching consequences.
Modern communication systems rely on multiple antennas that enhance the performance of network links using a series of techniques known as Multiple Input Multiple Output (MIMO). However, new technology is needed to meet the demands of a rapidly increasing number of wireless devices and enable the next generation of cellular systems. Known as Massive MIMO, this adaptation of traditional MIMO techniques presents challenges to research and development teams worldwide.
