  Abstract: This paper presents a framework that enables characterizing analytically the spectral efficiency achievable by device-to-device (D2D) communication integrated with a cellular network. This framework is based on a stochastic geometry formulation with a novel approach to the modeling of interference and with the added possibility of incorporating exclusion regions to protect cellular receivers from excessive interference from active D2D transmitters. To illustrate the potential of the framework, a number of examples are provided. These examples confirm the potential of D2D communication in situations of strong traffic locality, as well as the effectiveness of properly sized exclusion regions.
