Cognitive radio

Abstract

Cognitive radio holds an interesting promise for improved utilization of the radio spectrum. However, there is a considerable degree of uncertainty regarding the potential application of cognitive radio. One of the reasons for this uncertainty is the need for changes in the regulatory regime to allow for more dynamic forms of spectrum access. In addressing the necessary changes in regulations, the regulator should be well aware of the perspective of the entrepreneur. Eventually it is the entrepreneur who invests in CR technology and thereby realizes the goal of improved utilization of the radio spectrum. This chapter addresses the relationship between the regulations and the CR technology. Both the regulations and the CR technology will pose limitations on the possible business cases. It further proposes a way forward to come to a successful exploitation of CR technology in which the objectives of both the entrepreneur and the regulator can be realized.
