WS-03-Keynote-01: Fighting Exponential Traffic Growth - Is Mobile Network Energy Efficiency a Desperate Game?

Markus Gruber, Nokia Bell Labs, Germany (Sponsored by The IET (Institution of Engineering and Technology) - IET)
Room: Al Nakhil
Chair: M. Majid Butt (Trinity College Dublin, Ireland)

This talk starts with presenting energy efficiency in the light of historical developments, highlights energy consumption facts, and reveals the two biggest misconceptions about energy efficiency in networks. It also discusses methodologies for evaluating how green a network is and what to expect till 2020. Finally, a vision towards (near) zero power networking is sketched.

WS-03-Keynote-2: Doubly-massive MIMO Systems at mmWave Frequencies: Opportunities and Research Challenges

Stefano Buzzi, University of Cassino and Lazio, Italy
Room: Al Nakhil
Chair: M. Majid Butt (Trinity College Dublin, Ireland)

One of the key features of next generation wireless communication systems will be the use of frequencies in the range 10-100GHz (aka mmWave band) in densely populated indoor and outdoor scenarios. Although conventional wisdom has always considered mmWave frequencies unsuited for cellular communications, due to increased path-loss and atmospheric absorption, recent research results have shown that on distances up to one hundred meters or even more they are actually capable of providing astonishing data-rates, larger than 1 Gbps.Due to the reduced wavelength, antenna arrays with a large number of antennas can be packed in very small volumes, making thus it possible to consider, at least in principle, communication links wherein not only the base-station, but also the user device, are equipped with very large antenna arrays. We denote this configuration as a "doubly-massive" MIMO wireless link.This talk will focus on the fundamentals of doubly-massive MIMO systems at mmWave frequencies, showing the ultimate gains that they are able to achieve, but also highlighting the extraordinary research challenges (such as, e.g., the hardware complexity and the channel estimation problem), that they pose.

WS-03-Keynote-03: Energy Harvesting and Energy Cooperation towards Green and Sustainable Wireless Networks

Sennur Ulukus, University of Maryland, USA
Room: Al Nakhil
Chair: M. Majid Butt (Trinity College Dublin, Ireland)

Wireless networks composed of energy harvesting devices will introduce several transformative changes in wireless networking as we know it: energy self-sufficient, energy self-sustaining, perpetual operation; reduced use of conventional energy and accompanying carbon footprint; untethered mobility; and an ability to deploy wireless networks at hard-to-reach places such as remote rural areas, within the structures, and within the human body. Energy harvesting brings new dimensions to the wireless communication problem in the form of intermittency and randomness of available energy, which necessitates a fresh look at wireless communication protocols at the physical, medium access and networking layers. In addition, energy cooperation through wireless energy transfer enables controlled and optimized energy harvesting at the receiving end. In this talk, I will summarize recent research results on energy harvesting communication and energy cooperation in the fields of communication theory, information theory and wireless networking, and outline several open research problems.
