Office for mac. • • Part of the book series (BRIEFSELECTRIC) Abstract We discuss the key components of the current de facto spectrum sharing architecture, opportunistic spectrum access, including spectrum sensing, spectrum access, and spectrum handoff. We then discuss the challenges for the opportunistic spectrum access architecture. Next, we introduce a geo-location based spectrum access approach that is designed for the TV bands.

We discuss the TV band availability for secondary access, and present the framework of accessing idle TV bands.
