Key Issues

Cognitive radio aims at improving the way the radio spectrum is utilized. Today’s approach is based on dividing the spectrum into small pieces, each for a specific purpose. Since the applications use their spectrum to a limited extent, this leads to the unwanted situation of under-utilization of this scarce radio resource. While radio communications grow constantly, regulation authorities recognise that the current approach is reaching its limits. Consequently, cognitive radio and dynamic spectrum allocation are becoming key technologies and key research activities in the field of wireless communications.

SENDORA addresses this key issue and proposes a new approach and innovative techniques to support the coexistence of licensed and cognitive wireless users in a same area.
