  9. Flex5Gware project – General Picture The overall objective of Flex5Gware is to deliver highly reconfigurable HW platforms together with HW-agnostic SW platforms targeting both network elements and devices taking into account increased capacity, reduced energy footprint, as well as scalability and modularity, to enable a smooth transition from 4G mobile wireless systems to 5G. Objectives : Increasing HW versatility and reconfigurability 1. Designing and developing HW-agnostic, 2. flexible and cost-effective SW platforms Increasing the overall achievable capacity 3. provided by 5G communication platforms Decreasing the overall energy consumed by 4. 5G communication platforms Identifying and prototyping key HW and SW 5. building blocks and providing a proof of concept for all developments in Flex5Gware Legenda IEEE 5G Summit (Berlin, November 2, 2016) 9

  10. WP6 Focus: integration activities for the integrated PoCs and validation, testing and demonstration for all the PoCs (both standalone and integrated). Very strong implementation focus  11 proofs-of-concept IEEE 5G Summit (Berlin, November 2, 2016) 10

  11. Flex5Gware collaboration with 5G PPP: WP6 perspective and potential joint demonstrations  Flex5Gware will show its PoCs during a final demonstration event at the end of the project (Turin, June 2017).  Telecom Italia will host the Flex5Gware demonstration activities, thanks to the presence of TILAB facilities in Turin (Italy), as already done in the past for the EARTH project demonstrator.  The project’s intention is to also co-operate with research projects of complementary direction according to the 5G PPP structure, so as to address a holistic system perspective.  Cross-project demonstrations will be hosted as well as Flex5Gware PoCs during the final demonstration event in Turin.

  14. The path toward a fully virtualized network Motivation for mobile operators • Exponential increase in mobile traffic volume (forecast: 1000-fold increase by 2020). • This traffic will be unevenly distributed in time and space, due to the nature of mobile broadband connections. Scenario • Network deployment evolution should adapt to this demand by providing the required coverage, capacity and QoS (Quality of Service). More attention to energy efficiency and Operators operational costs (CAPEX./OPEX) needs • progressive usage of cloud technologies (traditionally born within IT market) applied to other business sectors (i.e. telco market), and in particular for mobile networks evolution. • Telecommunication market is already moving progressively toward virtual implementations of EPC, and recently operators are considering with increasing attention Emerging trends the centralization (C-RAN) and virtualization (NFV) of mobile networks functionalities in a standard IT platform. • This will result also in an highly efficient network, able to provide the needed system throughput by taking care of costs and utilization efficiency, and also energy efficiency and sustainability of the mobile network evolution. Benefits • All these aspects are currently carefully evaluated by operators, in the view of future network deployments, suitable for additional revenue generating services.

  15. Mobile Network path toward C-RAN and virtual RAN  As a consequence, a possibility for operators is to evaluate virtualization of networks, potentially including also RAN (Radio Access Network).  But, before talking about vRAN, it is worth to consider C-RAN evolution path, starting from present LTE flat architecture.  In fact, some evolutive steps of the mobile network toward virtual RAN implementation should be envisaged (vRAN is the last step of an evolution/revolution).  NOTE: C-RAN architecture can be applied for both macro-only and HetNet scenarios. In this context we will refer specifically to HetNets. IEEE 5G Summit (Berlin, November 2, 2016) 15

  16. C-RAN evolution path … • Compacted architecture consists in Baseband unit and Radio unit joint in same module. • A splitted architecture (with BB unit and Radio unit in different modules) can be seen as a first centralization step toward C-RAN architecture. • In C-RAN architecture baseband resources shared (pooled) across RRUs.
