Spatial Capacity of Random Access Poisson Wireless Networks

This paper introduces a novel approach to evaluate the physical limit of ad hoc networks based on their spatial capacity, defined as the maximum spatial spectral efficiency supported by the network while a vanishing error probability is guaranteed for all communication links. Specifically, the spatial capacity together with upper and lower bounds is derived in closed-form for networks where transmitters follow a Poisson point process and their respective receivers are located at a fixed distance. In this scenario, the spatial capacity is achieved using an adaptation technique that sets the link spectral efficiency in accordance with the distance between the receivers and their closest interferers.
