Executive Summary

This paper surveys and unifies a number of recent contributions that have collectively developed a metric for decentralized wireless network analysis known as transmission capacity. Although it is notoriously difficult to derive general end-to-end capacity results for multi-terminal or ad hoc networks, the Transmission Capacity (TC) framework allows for quantification of achievable single-hop rates by focusing on a simplified physical/MAC layer model. By using stochastic geometry to quantify the multi-user interference in the network, the relationship between the optimal spatial density and success probability of transmissions in the network can be determined, and expressed - often fairly simply - in terms of the key network parameters.
