TV White-Space Video Streaming Demo

In November 2008, FCC approved unlicensed use of TV white space. This marks an important milestone in the reality of using cognitive radio for communication. In this demonstration, we show how spectrum sensing can effectively sense the presence or absence of the incumbent users. The vacant channels sensed can then be used for wireless communication such as wireless video streaming shown in this demonstration. At the same time, we will also show the difference in sensitivity using spectrum sensing and typical digital TV receiver. With successful demonstration of such system in real-world environment, it will give the much needed confidence in the capability of cognitive radio systems to detect the operation of primary users and protect their use of spectrum.
