A major performance limiting factor in wireless networks is interference. Current wireless networks are designed based on the principle of interference avoidance, which advocates for eliminating concurrent nearby transmissions to avoid collisions, as collisions result in waste of scarce wireless bandwidth. The key issue is that a network design that blindly prevents interference is sub-optimal and results in severe inefficiencies in bandwidth-limited wireless networks. With recent advances at the physical layer of wireless networks, concurrent transmissions of nearby links can be successfully decoded if controlled properly. If transmitters and receivers are aware of the interference structure, they can exploit it to better decode their transmissions, and thus greatly improve network performance.

无线网络中的一个主要性能限制因素是干扰。当前无线网络的设计基于干扰避免原则，该原则主张消除并发的附近传输以避免冲突，因为冲突会导致稀缺的无线带宽的浪费。关键问题是，盲目防止干扰的网络设计不是最优的，会导致带宽有限的无线网络的严重低效。随着无线网络物理层的最新进展，如果控制得当，附近链路的并发传输可以成功解码。如果发送器和接收器知道干扰结构，他们可以利用它来更好地解码他们的传输，从而极大地提高网络性能。
