New Spectrum and Spectrum Sharing Opportunities
Emerging spectrum bands for data span from 100s of MHz to THz. Such bands have radically different features with significant implications spanning from network design to spectrum sharing requirements. In this talk, I will discuss network and protocol designs exploiting diverse spectrum.

5G requirements. Telefónica vision
5G requirements are being setting now. The presentation will summarize Telefónica view on these requirements: it is not only about higher bandwidth and lower latencies. The evolution should solve some of the key problems of the mobile networks and business today like:
• Sustainability making a more efficient network able to provide service with higher performance with less cost than today networks
• Controlling device behavior
• Multiservice approach dealing with emergency services, M2M and many other services that will arrive
Also the way the evolution should be implemented is as well described. Evolutionary way is a need, putting in value a smooth evolution of 4G.

WiFi-XL: A license-free cellular network
Today’s cellular networks are centrally managed and require a low-latency control plane. This can be prohibitively expensive for many scenarios of interests, such as deployments in developing regions and/or license-free frequencies. Conversely, WiFi is inherently decentralized but not suitable for wide-area deployments. In this talk we will discuss WiFi-XL, a novel cellular network architecture that takes the best of both worlds: it is decentralized, it can be deployed in license-free frequencies and it provides a wide-area coverage.

5G mm-wave and optical wireless links for converged multi-Gb/s access and beyond
We present recent comercially-realisable technology solutions for ultra-capacity wireless (optical and V- and E-band) links suitable for converged multi-Gb/s access architectures. We will discuss recent results from the European FP7 SODALES project, which deploys an innovative active remote node (ARN) topology to enable increasingly important network functions such as SDN and NFV. We will also discuss the implications of mm-wave technologies for small-cell architecture design, in terms of spectral efficiency, latency, power consumption, and also for high capacity adhoc mesh networking.

A look to the Future Through the Rearview Mirror: 5G, Spectrum Congestion, and TVWS – or having right assumptions
In this talk we provide a short and critical view on the possible avenues towards future R&D in 5G domain. In particular we address the issues of spectrum congestion and traffic explosion that have been referred as one of the urgent challenges needing an action. The current proposals to address this problem domain include a gradual and evolutionary development of 4G networks towards 5G, more aggressive development of 5G with untested but promising technologies, and radical proposal such as use of Dynamic Spectrum Access capable cognitive radios. Similarly, there are also proposal to develop entirely new approaches for developing economies or evolving Wi-Fi type of systems for even more massive use.
The traffic increase and spectrum crunch claims are not limited to cellular bands, but the same claims have been made also for unlicensed bands. Quite recently then-Chairman of the FCC Genachowski stated, “Wi-Fi congestion is a very real and growing problem.” We will discuss about the spectrum congestion and argue that the situation is often over simplified in a public discourse. We use this discussion as a springboard to outline some of the recent results that have emerged from cognitive radio research community, and then proceed to ask generally on what assumptions and premises which should base the development of future wireless networks.

Shaping 5G
In this talk we will discuss the development of the future 5G systems. We will start from a vision of the future communication scenarios that will push the systems beyond the limits of currently available technologies. Based on these scenarios, we will derive the corresponding technical requirements and discuss how a single set of requirements will not fit all the needs. Then, we will discuss emerging evolutionary and disruptive technologies, and the role of these technologies in matching the different set of requirements. Finally, we will discuss how current trends call for a redefinition on the traditional “cell-centric” architecture.
