Talk 1
Title: Spectrum without Bounds – Networks without Borders
Abstract:
This talk traces the major activity in the spectrum policy and regulation world that is leading to the freeing up of spectrum and to an increased focus on sharing. The talk will briefly focus on the key ideas that are emerging and on that basis it will speculate about two futures.
The first is one that presents a vision for future mobile and wireless networks which we call Networks without Borders (NwoB), is based on a market-place of virtual network operators which construct networks from a pool of shared resources (e.g. basestations, spectrum, core network components, cloud resources, processing capabilities etc.). The resources will be sourced from traditional industry players as well as crowdsourced from individuals. The new forms of service provider will be facilitated by virtual network operators. These operators will control virtualised slices of the physical resources aggregated from the pool to create customized virtual networks on which to offer specialised services to end-users. There will be a high level of dynamism involved; unneeded resources will be returned to the pool for redeployment by other service providers. This model broadens the definition of infrastructure provider through significantly leveraging user-deployed infrastructure in a systematic manner. This model extends the sharing economy deeper into the mobile network through extensively embracing sharing of all types of resources, especially the spectrum. The model fundamentally redefines the term mobile network operator as a highly virtualised entity using heavily shared heterogeneous resources.
The second vision is one in which the mobile operator as we currently understand. It embraces spectrum sharing but in a way that is very much based complementary to is current business model. In doing this it encloses spectrum sharing for its own end and removes the potential for really disruptive innovation.
The audience will be asked to speculate about both approaches.

Talk 2
Title: 5G – A Complex Matter?
Abstract:
Telecommunication systems have evolved, from being simple monolithic structures to complex ones. Mine is an attempt to recast telecom systems in the language of complex systems, aiming at applying the tools and philosophy of complex systems science to wireless communication networks. Complex systems are those systems where simple entities interact in a nonlinear way, producing interesting (i.e. complex) results, with very little coordination and basically no planning assumed. By the investigation of complex wireless networks (composed by simple wireless devices, e.g. femtocells, or WiFi access points) I attempt to:
- Move towards a comprehensive and rigorous study of complex communication systems;
- Use local information and adaptations, to achieve global network-wide behaviour;
- Target specific applications of complex systems science to telecom systems, e.g. self-organizing radio resource allocation.
Another line of research I’m working on is 5G systems. I will discuss some emerging wireless trends, i.e., spectrum white spaces detection techniques, massive MIMO, and dense cellular deployments. I will also try to discuss whether there is a point in considering 5G systems as complex communication systems.
