Millimeter Wave: The Future of Commercial Wireless Systems

Millimeter wave (mmWave) is coming to fifth generation (5G) cellular, wireless local area networks (WLANs), and wireless personal area networks (WPANs). The benefits of using millimeter wave carriers arise from the potential for larger bandwidths (hundreds of megahertz to gigahertz) compared to lower carrier frequencies. Differences in the propagation, challenges introduced by hardware constraints, and computational issues related to the high data rates have reinvigorated research in wireless communications. This paper, which accompanies a keynote talk with the same name, provides a roadmap to the author's research results in the evolving area of mmWave for consumers.
