Title: Millimeter-wave technology trends for 5G and Wireless Transmission applications and Technologies

Wednesday, 13th September
Room: Salón de Actos, Colegio Arzobispo Fonseca


High interest in millimeter-wave bands has risen in the recent years due to the enormous amount of under-utilized bandwidth that lies in this part of the electromagnetic spectrum. The significant advantages offered by the propagation characteristics in terms of frequency re-usability and large channel bandwidths, make millimeter-wave suitable for the very high capacities required by 5G enhanced Mobile BroadBand (10 Gpbs peak throughput and 10 Mbps/m2).

The millimeter-wave bands can be suitably used for the access networks to increase the throughput to the User Equipment and the backhaul/front-haul of the base stations. At the same time the use of millimeter-wave bands, thanks to very compact antenna size that makes products ``blend'' in the environment, allows the densification of the cells in dense urban scenarios.

This keynote will address the following topics:

  • 5G key requirements driving evolution of mobile access and wireless x-haul to millimeter-wave and sub-millimeter ranges
    • Analysis of the most important requirements of 5G to drive the trends and technology at (sub-)millimeter-wave bands for wireless backhaul / front-haul network
  • millimeter-wave access:
    • application scenarios and potential bands for 5G at millimeter-wave,
    • Massive MIMO architectures comparison
    • hybrid beam-forming architectures
    • technology challenges
  • millimeter-wave backhaul
    • how backhaul can meet the demand of capacity and network densification
    • current spectrum use, considerations on new needs deriving from mobile access moving to higher frequencies
    • new spectrum above 100 GHz and innovative ways to use it
    • millimeter-wave technical/technological trends
    • Research activities in the D-Band (130 to 175 GHz) for outdoor backhaul applications: Standardization status; Technology overview (semiconductor trends); MMIC; Antenna; Engineering solutions; Field trial registration results

From the considerations outlined so far it is relatively easy to evince the importance that the research will play in the next years in the many areas that will be necessary to cover in order to develop systems capable to operate at very high capacity with spectral efficiency, high performance, at frequencies up to 175 GHz.


Renato Lombardi is the Director of Huawei’s Research Centre in Milan, Italy. He oversees the development of microwave technologies and the implementation of innovative mobile broadband backhauling networks across Europe.

Mr. Lombardi graduated from the Politecnico di Milano. He previously led the Microwave Technical Sales Department for Siemens in Germany and was later appointed to Head of Research & Development. As a result of the Siemens and Nokia joint venture in 2006, Mr. Lombardi became a member of the integration team and later Head of Product Management of the Microwave Business Line.

Renato joined Huawei in 2008 and was responsible for establishing the microwave division of R&D in Milan. In 2011, he was awarded the title of ‘Fellow of Huawei’.

Title: Network Localization and Navigation: Signal Processing Opportunities

Thursday, 14th September
Room: Salón de Actos, Colegio Arzobispo Fonseca


The availability of positional information is of extreme importance in numerous wireless applications. The coming years will see the emergence of location-aware networks with sub-meter localization accuracy, minimal infrastructure, and high robustness in harsh (GPS challenged) environments. To reach this goal we advocate network localization and navigation, a new paradigm that exploits a combination of wideband transmission and spatiotemporal cooperation. Our work has addressed this problem from three perspectives: theoretical framework, cooperative algorithms, and network experimentation. This talk will provide an overview of our recent research results in this exciting field.


Moe Win is a Professor at the Massachusetts Institute of Technology (MIT). Prior to joining MIT, he was with AT&T Research Laboratories for five years and with the Jet Propulsion Laboratory for seven years. His research encompasses fundamental theories, algorithm design, and network experimentation for a broad range of real-world problems. His current research topics include network localization and navigation, network interference exploitation, intrinsic wireless network secrecy, adaptive diversity techniques, and ultra-wideband systems.

Professor Win is a Fellow of the AAAS, the IEEE, and the IET, and served as an IEEE Distinguished Lecturer. He was an elected Member-at-Large on the IEEE Communications Society Board of Governors (2011-2013). He was the Chair (2004-2006) and Secretary (2002-2004) for the Radio Communications Committee of the IEEE Communications Society. He was honored with two IEEE Technical Field Awards: the IEEE Kiyo Tomiyasu Award and the IEEE Eric E. Sumner Award (jointly with Professor R. A. Scholtz). He received the IEEE Communications Society Edwin H. Armstrong Achievement Award, the International Prize for Communications Cristoforo Colombo, the Copernicus Fellowship, the Royal Academy of Engineering Distinguished Visiting Fellowship, Institute of Advanced Study Natural Sciences and Technology Fellowship, the Fulbright Fellowship, the Laurea Honoris Causa from the University of Ferrara, and the U.S. Presidential Early Career Award for Scientists and Engineers.

Title: Cost-, Spectrum-, and Energy-Efficient Distributed Collaborative Beamforming Designs for Real-World Applications

Friday, 15th September
Room: Salón de Actos, Colegio Arzobispo Fonseca


Collaborative beamforming (CB), alternatively known as cooperative multi-antenna relaying, stands out today as a strong means to increase coverage, reliability, and capacity of various wireless networks by implementing through a set of terminals (sensor nodes, mobiles, network relays, soldier radios, vehicles, etc.) dual-hop transmissions between transmitter-receiver pairs when direct links would otherwise fail. Distributed CB (DCB) designs, in particular, lend themselves to distributed processing implementations that avoid the costly overhead required otherwise to broadcast the CB weights after their calculation by some master terminals. Many impediments stand, however, between the exciting concept of DCB and its real-world and wide-use applicability.

In this talk, we present novel DCB designs, obtained in closed form, that do not require any data exchange between terminals, yet properly cope, as dictated by a broad range of applications, with both scattered and interfered multi-antenna dual-hop transmissions under different power constraints. We also analyze the performance of these new DCB designs in terms of SNR and link-level throughput, both by newly established theoretical closed-form expressions and simulations to illustrate their spectrum, power, and computational-cost efficiencies in real-world operating conditions that account for various implementation imperfections.


Sofiène Affes received the Diplôme d’Ingénieur degree in telecommunications and the Ph.D. degree (Hons.) in signal processing from the École Nationale Supérieure des Télécommunications, Paris, France, in 1992 and 1995, respectively. He was a Research Associate with INRS, Montreal, QC, Canada, until 1997, an Assistant Professor until 2000, and an Associate Professor until 2009. He is currently a Full Professor and Director of PERSWADE, a unique U.S. $4M research training program on wireless in Canada involving 27 faculty members from 8 universities and 10 industrial partners.

From 2003 to 2013, he was a Canada Research Chair in Wireless Communications. He has been a recipient of a Discovery Accelerator Supplement Award twice from NSERC, from 2008 to 2011 and from 2013 to 2016. He is an Associate Editor for the IEEE Transactions on Communications and the Journal on Wireless Communications and Mobile Computing (Wiley). He was previously an Associate Editor for the IEEE Transactions on Wireless Communications and the IEEE Transactions on Signal Processing. He already served as a General Co-Chair of the IEEE VTC’2006-Fall and the IEEE ICUWB 2015, both held in Montreal, QC, Canada.

For his contributions to the success of both events, he received a Recognition Award from the IEEE Vehicular Technology Society in 2008 and a Certificate of Recognition from the IEEE Microwave Theory and Techniques Society in 2015. He is currently serving as the General Chair of 28th IEEE PIMRC to be held in Montreal in October 2017.
