MORE SPECTRUM: MM-WAVE
WILL IT PROVIDE COVERAGE AT COST?
• Mm- wave for outdoor or indoor access
• Lots of mm-wave spectrum
• Bursty traffic,
High rate …. when covered
Propagation is mainly line of sight  Arrays
Cost and energy efficiency
 efficient silicon
Dense deployment (overlapping coverage)
Tracking of users needed
Coverage
at cost?

• Main drivers for 5G:
- Extended range of services and use cases
Small traffic, low latency, availability
- Cost, energy and signaling efficiency in the
networks
- Simple and SDN/NFV-compatible architecture
integrating legacy RAT
Conceptual work
Focusing: Evaluation /
integration/ selection
Integration, Engineering, trials

H2020 Call2 - 5GPPP-
Phase 2
- The focus of the projects should evolve with the maturing of the topics
- Early phase: Conceptual work, scouting
- Focussing phase: Quantitative evaluation, Assessment and selection of the technologies, integration of a
system
- Integration and Engineering phase
- Phasing : Number of people that can drive the process is limited. Phases should stay sequential.

GAPS IN THE CURRENT SET OF PROJECTS
• Linkage to evolving an applications community
- Need to track requirements and to link to stakeholders on the applications side
- Allow app stakehoders to “play” with the new possibilities
• Some topic areas will extend or split to allow for deeper coverage
- Introducing more extensive evaluation: modeling, simulation frameworks
- Attaching a targetted prototyping activity to accommodate for sufficient resources
- Deeper coverage of specific topics
• New questions will come up:
- E.g. the impact of virtualization and multi-tenancy on “business” within the network,
accounting is becoming crucial. This has significant regulatory and legal implications.

Examples for research questions
resulting from cross-topics
• Cross- projects: Some interactions between the “last” pre-structuring projects
need more in-depth studies
- This is currently being accounted for in bi-lateral interactions between the Px projects
but dedicated studies need to follow

EXTENDED PARTNERSHIP MODELS
- The interest in participation to the PPP projects is much larger than
what they can handle
- Many academic partners would like to join PPP, but cannot be accommodated
- Many non-EU parties seek linkage
- Currently captured in EU-Japan, EU-Korea, EU-China
- This approach does not scale easily, there are many more candidates ….
- Dilemma : If we increase the PPP projects size to accommodate more partners and parties, projects
loose focus and efficiency
- Consider a structured approach, creating a co-operation platform “around” the projects.

DEMOS AND PROTOTYPES – GENERAL CONSIDERATIONS
• Demos should show
- The mastering of a technical challenge
- The impact of a new technology
• Realization
- Demos may be pure (software) models, just visualizing properties and impact of a technology
- Can also consist of a prototype plus a human interface to allow for more insight
- This is clearly the preferred type
• De- risking and relevance
- Prototypes should closely relate to the critical research questions of the project
16

DEMOS AND PROTOTYPES – GENERAL CONSIDERATIONS
• Limited effort:
- Prototypes rely on simplifications and abstractions to become viable (e.g. one scenario, few
users)
- Use abstractions for non-relevant parts
- Lack of statistical richness: Generally, prototypes are not a good vehicle to answer
performance questions
(Apart from e.g. peak rates ) since they represent limited numbers of nodes and users
- Realization perspective: Realization of a prototype leads to an implementation view and
related learning. It adds another perspective to research.
