Abstract: Cognitive radio capabilities will lead to the ubiquitous availability of a great variety of innovative services, delivered via a multitude of Radio Access Technologies (RATs). To achieve this vision, heterogeneity in wireless access technologies; including the requirements and capabilities of different services, mobility patterns, devices, and so forth. Since the demand for spectrum gradually increases and will continue to do so in future systems, this paper present some key-issues with respect to efficiently managing spectrum and brought into view the relevant regulatory perspectives. Moreover, the usage of spectrum will not fluctuate between extreme limits, but be constantly at a rather satisfactory level, giving the opportunity to stakeholders to create, introduce and experience innovative services and applications.
Keywords: Cognitive Radio, Radio Access Technologies (RATs), Cognitive Pilot Channel (CPC), Dynamic Spectrum Allocation (DSA).

Scope of the Article: Radio Over Fiber
