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.

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施，其容量随用户需求的增长而扩展。无线频谱是有限的;然而，无线需求可以无限增长。无线用户长期以来一直遭受蜂窝和Wi-Fi网络无法跟上由移动的设备和应用的增长所导致的增加的需求的困扰。尽管近年来个人无线设备已经有了显著的改进。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;用户需求随着网络中的设备数量而增加，但网络吞吐量却没有。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，预计的需求将继续超过预计的容量。该项目将提出第一个实用的系统，可以使无线局域网保持增加其吞吐量简单地通过添加额外的接入点（AP）在同一信道上。它将与现有的未经修改的终端用户设备一起工作，并展示与当今无线技术相比吞吐量提高10倍的能力。该项目更广泛的影响/商业潜力将是开发新的干扰最小、适度降级的无线系统和宽带解决方案，以及由此提高频谱利用率所带来的财务、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，对于企业、学校、家庭、公共安全工作者等社会各个部门都是不可或缺的。即使面对当前的容量紧缩，也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，并促使政府启动了国家无线创新和基础设施计划。一项新技术可以使无线网络扩展其容量以跟上蓬勃发展的需求，并提供10倍的吞吐量增益，与今天相比，可以提供对现有应用的改进访问，如医疗测试，在线课程，高速视频，基于云的服务等，并实现新类别的应用、设备和服务。它将推进政府的目标，即通过在价值400亿美元的企业无线、运营商Wi-Fi和蜂窝市场上的本土创新，实现美国经济增长和竞争力。
