On the Accuracy of the Wyner Model in Downlink Cellular Networks
Compared to real cellular systems where users are spatially distributed and interference levels vary by several orders of magnitude over a cell, in the Wyner model user locations are fixed and the interference intensity is characterized by a single fixed parameter. Although it is a fairly extreme simplification, the Wyner model has been extensively used to analyze cellular networks. Does it capture some of the main trends of such networks or not? In this study of downlink cellular networks, the authors show that from an outage point of view, the Wyner model is highly inaccurate since outage is primarily a function of user location.
