无线连接从根本上改变了我们与世界连接和互动的方式。在过去十五年中，无线数据使用量呈指数级增长，预计这一趋势将持续下去。无线连接的总体容量是有限的，因为它在电磁频谱上运行，并且可用的频谱范围既有限又已经稀缺。我们认为，我们目前看到的需求增长从长远来看是不可持续的，因为频谱资源将完全耗尽。虽然当前的研究致力于提高频谱效率，但未来的提高将带来收益递减。在这项工作中，我们介绍了与最大化无线系统效率相关的当前技术和前沿研究，并提出了当我们接近无线连接极限时将变得至关重要的研究问题。
Wireless connectivity has fundamentally changed the way we connect and interact with the world. Over the past fifteen years there has been an exponential increase in wireless data usage, a trend that is predicted to continue. The overall capacity for wireless connectivity is limited in that it operates over electromagnetic spectrum, and the usable range of spectrum is both finite and already scarce. We argue that the growth in demand that we currently see is unsustainable in the long-term, as spectrum resources will become fully exhausted. While current lines of research seek to increase spectrum efficiency, increases in the future will achieve diminishing returns. In this work we present current technologies as well as cutting-edge research related to maximizing the efficiency of wireless systems, and offer research questions that will become critical as we near the limits of wireless connectivity.
