Open spectrum policy mostly deals with the shared-use of spectrum resources which again utilizes the orthogonality in different spectral domains - geography, space, power, frequency and time. Among these, temporal share of the spectrum, known as CR or cognitive radio technology, allows secondary licensees to opportunistically access the spectrum during the absence of the first. This paper provides the analysis on the performance of CR implementations in IEEE 802.22 WRAN system, in terms of the spectrum utilization rate, along with simulation results. Also discussed are the regulatory issues in introducing open spectrum policies into the market, centered on the reuse of spectrum resources.
