Goals
Develop a trial environment for cognitive technologies in wireless
communication.
Define an interface between cognitive solutions and cognitive
networks or devices.
Research and develop cognitive solutions for selected use cases.
Verify the performance of the cognitive solutions, using the trial
environment and the open interface.
Clarify the expected changes in the business environment,
arising from cognitive technologies. Explore models for the
successful regulation, standardization, and commercialization of
cognitive solutions and the promotion of new business.

Goals
Hosting CORE trial environment
Incrementally develop new solutions
Interface other solutions
Supporting the continuity by keeping the
previous research results alive
Showroom
CORE related enablers in CNL
Virtualisation technologies (VMware, Xen)
Funet access, 1Gbps LAN network, WLANs,
routing
VTT's QoSMeT measurement tool provides real-
time passive E2E and multi-point QoS
measurements
Traffic generators
Distributed Control and Management Framework
(DCMF) VTT's handover assistant combines
multiple handover decision related triggers in
both terminal and network side

CORE trial environment
Cognitive experiment includes configuring of a trial setup,
testing, ordering, customer system integration, and
carrying out measurements.
Cognitive engine collects various data from the the
customer system for decision making.
Cognitive engine is able to perform configuration changes
to the customer system and observe results.
Customer is able to change the decision logic and
configuration.
Trial users are able to use a new cognitive service.
Service/application can send an application request to the
cognitive engine.
Trial environment allows researchers to carry out experiments in the limits of developed
cognitive trial setups such as upcoming LTE on white spaces.

CWC’s WARP trial environment
1308/06/2011
Goals
Operators want opportunistic spectrum usage (OSU) to
increase their resources in rush hours or more permanently
• TV white space, ISM band, Femto cells
Operators want to optimize usage of their local resources
• One operator has several resources on the area
E.g. WLAN, LTE
• Several operators have resources on the area,
interoperator cooperation
1408/06/2011
Consequences
We need networks that emulate cellular networks
• Base stations
• User nodes
We need ability to go to white spaces and back
• and the one who is controlling that
We need more than just one network to demonstate
• Original and white space networks
• Resource sharing between different nets
1508/06/2011
What we have now
10 WARP platforms that
• Have base implementation of PHY and MAC (”OFDM
WLAN”)
• Can be modified (within limitations)
• Can be connected to each other by cable or radio link,
to internet or to PC to form nets
We have added
• Ad hoc MAC
• Spectrum sensing capability
• Sensing based cognitivity
1608/06/2011
Plans, work going on in CORE
More (next generation) platforms
• Larger nets
• Different kind of nets that can be joined
Cellular network emulation capability
• TDMA/TDD
• CSMA/TDD
• Base station capability
More sophistigated database/sensing based cognitive engine
More measures to support cognitive engines
• SINR etc
Cognitive engines based on new measures, not just
database

Research questions
Generic
Performance: Latency, BER, Service availability, Service continuity
Video quality vs. number of users in cell (competing interests, users vs. operator)
Ways to improve performance, performance improvement by use of Cognition API?
Number of users which can be served in case of streaming and “broadcast over IP”
Use of traffic classes
Multicasting (does LTE support “real” multicasting where traffic for multiple users is sent only
once on physical layer?)
Advances in device technologies
Future source coding technologies
Cost evaluation
Cost for providing the service, according to the subscriber scenario
Potential for and viability of price differentiation
Overall economic viability
Ways to improve economic viability
Adaptive source coding
Regulatory or other constraints on source coding method
Necessary techniques and protocols
2008/06/2011
Future plans
Implemention of Cognition API / Engine in live network infra
EAST
Terminal end
IPTV pilot planning
Use cases
On-field analysing
WP1 and WP3 inputs and outputs
Integration of trial environments

Summary
Expected outcome of CORE project:
There is an open trial environment and service, enabling
customers to discover and order test resources for their
cognitive solutions.
Cognitive engine functionality has been implemented and its
performance verified for the selected use cases.
The status and direction of relevant regulation and
standardization is known. The impact and role of cognitive
solutions to the business environment is understood.
