Cognitive radio is the restorative technology to authorize the efficient usage of restricted natural resource radio frequency spectrum for the wireless devices. The technology empowers the telecommunication industry by renovating the traditional static spectrum access approach to dynamic spectrum access to stimulate the unlicensed users to access underutilized licensed band; without creating any/allowable interference for licensed users. This paper provides the notion of the radio frequency spectrum facet that is required to understand the significance of Cognitive Radio technology in future. Various associated challenges with the realization cognitive radio technology are also highlighted in this paper.
