“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

Network automation (SON) in uncertain information environment calls for use of AI

Small cells and WiFi will become seamless part of the network

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
