SBIR Phase I: Wireless Networks that can Scale Capacity with User Demands

这个小型企业创新研究计划（SBIR）第一阶段项目将展示无线网络的设计和实现，其容量将随着用户需求的增加而扩大。无线频谱是有限的；然而，无线需求可以无限增长。长期以来，无线用户一直遭受蜂窝和Wi-Fi网络无法跟上移动设备和应用程序增长所带来的需求增长的困扰。尽管近年来个人无线设备已经有了巨大的进步。问题在于用户需求规模和网络吞吐量规模之间存在不匹配；用户需求会随着网络中设备数量的增加而增加，但网络吞吐量不会。除非网络吞吐量也随着设备数量的增加而增加，否则无线网络将始终难以满足其需求，并且预计的需求将不断超过预计的容量。该项目将展示第一个实用的系统，它可以使无线局域网通过在同一信道上添加额外的接入点（ap）来不断增加其吞吐量。它将与现有的未经修改的终端用户设备一起工作，并且与目前的无线技术相比，吞吐量提高了10倍。该项目的更广泛影响/商业潜力将是开发新的最小干扰、优雅退化的无线系统和宽带解决方案，以及由此带来的频谱利用率提高所带来的财务、社会和生产力效益。高速无线接入在现代经济中发挥着关键作用，是企业、学校、家庭、公共安全工作者等社会各个部门不可或缺的一部分。尽管面临当前的容量短缺，但仍需要支持无线的持续增长，这使得频谱的有效利用成为国家优先事项，并促使政府启动了一项国家无线创新和基础设施倡议。一项新技术可以使无线网络能够扩展其容量以跟上迅速增长的需求，并提供比目前提高10倍的吞吐量，可以提供对现有应用程序（如医学测试、在线课程、高速视频、基于云的服务等）的改进访问，并支持新类别的应用程序、设备和服务。它将通过在价值400亿美元的企业无线、运营商Wi-Fi和蜂窝市场上的自主创新，推动政府实现美国经济增长和竞争力的目标。

This Small Business Innovation Research Prgram (SBIR)Phase I project will demonstrate the design and implementation of a wireless network whose capacity scales with increasing user demand. Wireless spectrum is limited; wireless demands can, however, grow unlimited. Wireless users have long suffered from the inability of cellular and Wi-Fi networks to keep up with increased demand resulting from the growth in mobile devices and applications. This is despite the fact that individual wireless devices have improved dramatically in recent years. The problem is that there is a mismatch between the way user demands scale and network throughput scales; user demands scale with the number of devices in the network but network throughput does not. Unless network throughput also scales with the number of devices, wireless networks will always find it hard to keep up with their demands, and the projected demands will keep exceeding the projected capacity. This project will present the first practical system that can enable a wireless LAN to keep increasing its throughput simply by adding additional access points (APs) on the same channel. It will work with existing unmodified end-user devices, and demonstrate throughput gains of 10x compared to today's wireless technologies.The broader impact/commercial potential of this project will be the development of new minimal interference, graceful degradation wireless systems and broadband solutions, and the financial, social, and productivity benefits accruing from the resulting improvement in spectrum utilization. High speed wireless access plays a key role in the modern economy, and is indispensable for every sector of society: businesses, schools, homes, public safety workers etc. The need to support the continued growth of wireless even in the face of the current capacity crunch has made the efficient use of spectrum a national priority, and led the government to start a National Wireless Innovation and Infrastructure Initiative. A new technology that can enable wireless networks to scale their capacity to keep up with burgeoning demand, and provide 10x throughput gains compared to today, can provide improved access to existing applications like medical tests, online courses, high speed video, cloud based services etc., and enable new classes of applications, devices, and services. It will advance the government's goals of enabling American economic growth and competitiveness through homegrown innovation in the $40 billion enterprise wireless, carrier Wi-Fi, and cellular markets.
