The FCC recently announced new spectrum for millimeter wave. The new rules open nearly 11 gigahertz of high-frequency spectrum for mobile and fixed wireless broadband, which include 3.85 GHz of currently licensed spectrum and 7 GHz of unlicensed spectrum. This decision could prove critical for the U.S. to retain its leadership in the field of wireless communications.

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. Sujay Sanghavi and Prof. Sanjay Shakkottai of UT ECE have received a National Science Foundation (NSF) award for their work on "NeTS: Small: Inverse Problems from Cascades: Structure, Causation and Opinions." Professors Sanghavi and Shakkottai aim to develop a new theoretical and algorithmic understanding of these classic processes. Their  focus is on using cascades as an inference and learning tool, instead of merely a mathematically convenient model.
