With the increasing proliferation of different communication devices sharing the same spectrum, it is critical to understand the impact of interference in heterogeneous wireless networks. In this paper, the authors put forth a mathematical model for coexistence in networks composed of both NarrowBand (NB) and UltraWide-Band (UWB) wireless nodes, based on fundamental tools from stochastic geometry. Their model considers that the interferers are spatially scattered according to a Poisson field, and are operating asynchronously in a wireless environment. They first determine the statistical distribution of the aggregate interference for both cases of NB and UWB emitters.
