We address the problem of interference among multiple cognitive networks operating in the TV White Space (TVWS). We give a concise overview of the current activities undergoing in international standardization bodies towards the realization of communications in the TV White Space (TVWS). We define a new metric, namely spectrum availability, which is used to analyze the efficiency of Dynamic Frequency Selection (DFS) as a coexistence mechanism to enable neighboring cognitive networks to operate free of interference in TVWS. Our analysis demonstrate the intrinsic relationship spectrum availability holds with the TVWS channel set as well as statistical information, e.g., house-hold density, Internet, White Space (WS) radio AP market penetration. In addition, we present a case study of major Japanese wards/cities in order to predict future spectrum congestion in the aforementioned country.
