In this paper, the authors address two basic questions in wireless communication: First, how long does it take to schedule an arbitrary set of communication requests? Second, given a set of communication requests, how many of them can be scheduled concurrently? Their results are derived in an interference model with geometric path loss and consist of efficient algorithms that find a constant approximation for the second problem and a logarithmic approximation for the first problem. In addition, they analyze some important properties of the interference model and show that it is robust to various factors that can influence the signal attenuation. More specifically, they prove that as long as such influences on the signal attenuation are constant, they affect the capacity only by a constant factor.
