COST is supported
by the EU Framework Programme
ESF provides the COST Office
through a European Commission contract
COST
European Cooperation in Science and Technology
One of the longest-running European intergovernmental
frameworks supporting cooperation among scientists and
researchers. It allows the coordination of national-funded
research on a European level.

Problem statement
Cognitive Radio (CR) is posed to become one of the most
important technological breakthroughs in wireless
communications, yet the issues surrounding the regulatory
aspects of its introduction remain unresolved.
3
COST-TERRA
Objective
Techno-economic studies with the aim of assisting the
development of a regulatory framework of radio spectrum
access rules for CR-based wireless applications.
4
COST-TERRA
Activities
o Acting as a “think tank” of experts on CR and regulation.
o Analyzing input from R&D projects in the field of CR.
o Providing key outputs as proposals to regulators.
o Innovation through devising scenarios for CR deployment.
