Analysis of Interference Cancellation in mmWave Cellular Systems

In this research, WNCG visiting graduate student Amir Jafari, WNCG graduate student Jeonghun Park and WNCG professor Robert Heath address the benefits of interference cancellation in millimeter-wave (mmWave) cellular systems. Considering a multiple antenna communications system with transmitting and receiving antennas, the receiving antennas can either be exploited to decode data streams in order to achieve spatial multiplexing, or alternatively the receiving antennas can be used to cancel the interference.

Prof. Robert Heath Moderates Brooklyn 5G Summit Panel

5G technology will play a major role in the future of automotive systems. Exactly how this technology will be implemented is still up for debate. To discuss current research and possible directions for 5G, industry experts met in New York for the Brooklyn 5G Summit in April 2016.

Three WNCG Professors Awarded $1 Million for 5G Research

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.

Texas Wireless Summit 2015 Announces Keynote Speakers

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.  

WNCG Responds to FCC on Future of mmWave

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. 

The Death of 5G?

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.

What multislope path loss models tell us about the fundamental limits of wireless network densification in 5G and beyond

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.
