Title: The Future of Wireless Networks: More Cells, More Bandwidth and More Antennas
Abstract: This talk provides a high-level discussion on scaling capacity, and analyses how to make it physically possible to scale the cellular capacity by orders of magnitude. The three dimensions of densification, bandwidth, and spectral efficiency are discussed in detail. The one user per cell concept is introduced as the sweet spot for densification. The importance of idle modes, both for reducing interference and improving the energy efficiency in small cell networks is discussed. The impact of increased bandwidth on the power consumption is evaluated, and improving spectral efficiency with beamforming techniques is explored. Finally, the technology mix that can enable an average capacity of 1 Gbps per UE is derived.
Short bio: David López-Pérez is currently a member of Technical Staff at Nokia Bell Laboratories. Prior to this, David received the B.Sc. and M.Sc. degrees in telecommunication from Miguel Hernandez University, Spain, in 2003 and 2006, respectively, and the Ph.D. degree in wireless networking from the University of Bedfordshire, U.K., in 2011. David was also a RF Engineer with Vodafone, Spain, from 2005 to 2006, and a Research Associate with King's College London, U.K., from 2010 to 2011. David has done extensive work on cellular small cell and ultra-dense network performance analysis, inter-cell interference coordination and mobility management, has pioneered work on LTE and WLAN inter-working, forming part of the team that invented Wi-Fi Boost, which lead to 3GPP LWIP, and is the father of massive MIMO unlicensed (mMIMO-U); a technology that connects the dots among mMIMO and unlincesed spectrum. David has authored the book Small Cell Networks: Deployment, Management and Optimization (IEEE Press/Wiley, 2018), as well as over 120 book chapters, journal, and conference papers, all in recognized venues. He also holds over 41 patents applications. David received the Ph.D. Marie-Curie Fellowship in 2007, the IEEE ComSoc Best Young Professional Industry Award in 2016, and the IEEE WCNC'18 Best Student Paper Award of the track "Wireless Networks" in 2018. He was also a finalist for the Scientist of the Year prize in The Irish Laboratory Awards in 2013 and 2015. He is an editor of IEEE TRANSACTION on WIRELESS COMMUNICATIONS since 2016, and he was awarded as Exemplary Reviewer of the IEEE COMMUNICATIONS LETTERS in 2011. He is or has also  been a Guest Editor of a number of journals, e.g., the IEEE JOURNAL ON SELECTED AREAS IN COMMUNICATIONS, the IEEE Communication Magazine and the IEEE Wireless Communication Magazine.
