Abstract
In this paper we model the TV white space usage by a WLAN type secondary network. We derive a model that incorporates spatially non-uniform distributed user demand and terrain-based radio channel model. We follow the approach proposed by Electronic Communications Committee (ECC) and describe the interference from the pixels in the secondary area to the pixels in the TV coverage area. The demand is described by the household density and the radio channel is evaluated as attenuation between the pixels. We also study how well a Poisson point process (PPP) based interference model describes the actual interference. We modify the PPP model so that it can describe non-uniform user distribution and terrain-based channel model. The proposed model describes the actual interference as a sum from multiple areas. We study how the size of the selected areas impacts the approximation of the actual interference distribution.
