Introduction of CWC Oulu

• A research unit
• Of the University of Oulu
• Active in transfer of know-how
• In wireless communications

What is CWC Oulu?
3
Mission

• To conduct scientific research supporting users
  and developers of wireless communication systems
  in their research, development and application
  projects.
• To enhance the flow of information between the
  academic community and the users and developers
  of wireless communications.
• To cultivate research results into new product
  and system concepts to help create new business
  opportunities and services.
• Raise top experts in wireless communications.

4
Principles of Operation

• Pure research unit no teaching responsibilities.
• No financial profit is sought.
• Operation is based on external funding only.
• An international contact and co-operation network
  is actively utilized.
• Results of work are actively published in
  scientific journals and conferences.
• Goal to be among the leading wireless
  communication research units on a global level.

5
Status

• Established in September -95 to improve the
  efficiency of academic research.
• Staff of 37 persons
• post-docs
• doctoral students
• master students
• During 1999 eight research projects were active
  (total funding 8 MFIM 1.3 M).
• CWC premises reside in Technopolis.

6
Co-Operation

• Close co-operation with Telecommunication
  Laboratory of the University of Oulu.
• Potential partners and funders
• Large and small companies
• Operators and other network and service providers
• Research units
• Government organizations
• International and national RD funding agencies
• Co-operation is established for enhancement of
  know-how, not for funds.

CWC perspectives on future research in wireless
communications

• The role of system level knowledge is more
  important in future.
• Fast developing component technology enables
  implementation of quite complex transceivers.
• In future, TX and RX algorithms as well as
  air-interface parameters can be adapted according
  to the communication channel.
• Packet data is becoming more and more important.
• Bandwidths and centre frequencies will increase.
• Multiple standards are unavoidable software
  radios will be used.
