“Virtualization” at all levels will be critical to properly controlling
the network and the associated range of services
Commonplace in the computing industry; Telecom/Wireless is playing catch-up
This HAS happened
IT resource virtualization
Infrastructure sharing
Policy driven architecture
Outsource of operations
NaaS, IaaS, PaaS
This is happening NOW
All IP network to share BW
Silos converged network
DPI & Open API initiatives

Network automation (SON) in uncertain information environment calls for use of AI
Small cells and WiFi will become seamless part of the network
All cells & frequency layers unified & automatically managed by SON
Current SON does not deal with unclear data and unexpected cases

Objective: Analysis and design of heterogeneous backhaul and fronthaul
technologies for 5G and their joint optimization with the access, aiming
at an energy-efficient, scalable, highly modular, flexible,
reconfigurable and with reduced cost 5G design
• Convergence of heterogeneous technologies for access, backhaul and
fronthaul
Seamless integration of heterogeneous wireless, wireline optical and satellite
transport technologies
Ultra-broadband backhaul network modeling, smart resource control algorithms and
innovative planning
• Joint access, backhaul and fronthaul management
Design of techniques such as handover management considering jointly the RAN and
backhaul conditions or holistic routing considering jointly RAN status and backhaul
load, among others
Combined monitoring and management of RAN and transport
Enable low latency for inter-site communications and machine-type and device-to-
device fixed and mobile services
11
• Energy-efficient and scalable designs
Adaptability of the RAN, fronthaul and backhaul to substantially reduce the energy consumption while keeping the overall QoE
• Reconfigurable integrated backhaul design
Adjustable to varying load distributions, dealing with per-flow requirements and with traffic aggregates simultaneously
• Design of Backhaul and fronthaul for novel network architectures
Backhaul and fronthaul for Cloud-based network architectures
Support for centralized and distributed/flat architecture (including local-breakout support at RAN, fronthaul and backhaul level)
• Backhaul/fronthaul design for very dense small cell deployments
Solutions for very dense deployments, both indoors and outdoors
Advanced low-cost wireless solutions for small-cell backhaul

• The European Commission with top companies and
research institutions has launched the 5G PPP
• The 5G PPP is fostered, from the private side by the 5G
Infrastructure Association:
http://5g-ppp.eu/
• Europe-wide research effort to deliver the required
technology:
7 year research plan in three stages
700 M€ funded by the European Commission
3,500 to 7,000 M€ funded by top EU industries
14
• 5G networks constitute an unprecedented
technology revolution
• World competition among top-technology
regions to arrive first!
• European effort between public and private
institutions to be the winners
• Carefully drafted and well funded long term
research plan
