The FCC seeks to connect 19 million unserved Americans to broadband by 2020. These rural areas have yet to be fully connected to the Internet due to wireline infrastructure costs which exceed potential revenue opportunities. Even in heavily-populated environments with sufficient wireline infrastructure, capacity issues remain in congested stadiums, disaster recovery zones, and public transportation. Each aforementioned access challenge seemingly is well-suited for wireless mesh networks, but have yet to be fully solved. However, recently, there has been a sizable growth in radios operating in diverse frequency bands (e.g., TV white spaces) with emerging multi-antenna schemes. In this project, multi-user beamforming and diverse frequency bands are leveraged to significantly build upon the flexibility originally sought by mesh networks. In doing so, frequency-agile beamforming mesh (FabMesh) networks seek to truly scale in complexity and cost according to the user population and traffic demand. The work includes three key innovations: (i) client-side, beamforming-aware, and frequency-agile protocols to improve performance and reliability of clients, using contextual information and advanced physical layer techniques, (ii) analysis of spatial reuse and capacity for media access control in mesh networks which leverage multi-user beamforming, and (iii) scalable network deployments which leverage multi-user beamforming along the backhaul and adaptation across multiple frequency bands according to network demand. The project includes a number of hands-on courses for university students at all levels, "just in time" pedagogical approaches to thousands of online students, outreach to under-represented students and communities, and key industrial collaborations to accelerate the commercial adoption of FabMesh networks.

FCC试图到2020年将1900万未被发现的美国人与宽带联系起来。由于有线基础设施成本超过了潜在的收入机会，这些农村地区尚未与互联网完全连接。即使在人口稠密的环境中，有线基础设施也存在，体​​育场，灾难恢复区和公共交通中仍然存在能力问题。似乎每个上述访问挑战似乎都非常适合无线网络网络，但尚未得到充分解决。然而，最近，在带有新兴的多ANTENNA方案的不同频带（例如电视白空间）中运行的无线电量显着增长。在这个项目中，多用户波束形成和不同的频带被利用，以显着建立在最初是网络网络所寻求的灵活性的基础上。这样一来，频敏化的网格（FabMesh）网络试图根据用户人口和交通需求真正扩大复杂性和成本。这项工作包括三个关键创新：（i）使用上下文信息和先进的物理层技术，（ii）分析空间重复使用和在网络网络中的媒体访问能力分析，从而分析多种用户界限和（iii II II II）范围的多种速率，以及（iii II II II II II），使用多个频率伸缩的杠杆，（ii）分析空间重复使用和（iii II II II），使用多个速率以及（iii II II II）分析，（ii）分析空间重复使用的能力，以及（IIII），将型号的杠杆作用分析，以及（IIIII），将多种量子伸展的杠杆分析，以及（ii）分析，（ii）分析用于提高客户的性能和可靠性的客户端，波束形成和频率的协议，以提高客户的性能和可靠性，以及分析。根据网络需求。该项目包括各个级别的大学生的许多动手课程，对成千上万的在线学生的“及时”教学方法，向代表性不足的学生和社区推广，以及重要的工业合作，以加速商业采用FabMesh网络。
