We address the problem of interference between portable cognitive emergency wireless networks (PCENs) operating in the TV white space (TVWS). We use stochastic-geometric model to gauge the expected reduction of effective service area caused by the interference between adjacent PCENs. The modeling steps are introduced in a tutorial fashion, and our results reveal the intrinsic relationship that PCEN service area has with environmental and TVWS-related system parameters, such as number of available TV channels, density of PCEN networks, and path-loss attenuation exponent. Furthermore, we give an up-to-date and timely overview of the under going activities in international standardization bodies as well as regulations created toward the realization of communications in the TVWS.
