Current wireless network design is built on the ethos of avoiding interference. In this paper, the authors question this long-held design principle. They show that with appropriate design, successful concurrent transmissions can be enabled and exploited on both the uplink and downlink. They show that this counterintuitive approach of encouraging interference can be exploited to increase network capacity significantly and simplify network design. They design and implement AutoMAC, a novel MAC and PHY protocol that exploits recently proposed rateless coding techniques to provide such concurrency.
