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

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.
