无线产业已经为世界服务了超过世纪。在过去的30年里，蜂窝产业和无线移动的发展从根本上改变了全球人类通信的本质和社会化，现在几乎覆盖了地球上的每一个人。但随着它的成功，蜂窝通信也达到了一个连接点，一个变化点，提出了关于其目前形式的长期可持续性的问题。今天用于蜂窝通信的无线电频谱既分散又有限，并且在全球范围内仅提供千兆赫的频谱-这种情况使其不适合无线“大数据”传输的出现。为了将这种非常有限的频谱容量用于蜂窝通信的不断发展的角色，服务提供商正在部署增强的技术、网络拓扑和日益复杂的调制方法，以从该频带中提取剩余的网络容量。展望未来，鉴于无线数据的显著和持续增长，这些网络增强和对现有蜂窝和Wi-Fi频谱的依赖是否足以在未来维持语音和数据蜂窝基础设施和网络容量？或者，除了现有的基础设施之外，还需要新的高容量频谱、新的频谱政策、非传统技术和网络拓扑来满足新兴的蜂窝和无线数据挑战。
The wireless industry has served the world for more than a century. More recently over the last 30 years, the evolution of the cellular industry and wireless mobility has radically changed the very nature and socialization of human communications globally, now reaching almost every human being on the planet. But with its success, cellular communications is also reaching a nexus point, a point of change that raises questions as to its long term sustainability in its current form. The radio spectrum used for cellular communications today is both fragmented and limited in channel size, and in aggregation provides only a Gigahertz worth of spectrum worldwide - a condition making it ill-suited for the emergence of wireless “big data” transport. To utilize this very limited spectrum capacity for the evolving role of cellular communications, service providers are deploying enhanced technologies, network topologies and increasingly complex modulation methods to extract the remaining network capacity from this spectrum band. Going forward and in light of the remarkable and ongoing growth in wireless data, will these network enhancements and reliance on existing cellular and Wi-Fi spectrum alone be enough to sustain voice and data cellular infrastructure and network capacity well into the future? Or alternatively, and in addition to existing infrastructure, will new high capacity spectrum, new spectrum policies, non-traditional technologies and network topologies be required to meet emerging cellular and wireless data challenges.
