CNS Core: Small: Towards MIMO Power Line Communication for Scalability, Coverage and High Data Rate

该项目利用无处不在的电力线，通过允许多个设备同时发送/接收数据，实现高数据速率通信；目前，在给定的时间只有一个设备可以发送/接收数据。这项技术很有吸引力，因为它利用现有的电力线工厂，可以与现有的无线接入点一起工作，以提高可靠性，覆盖范围和数据速率。它对现有的互联网技术有着深远的影响。它可以作为现有无线接入点的骨干网络，共享协调信息、控制和数据，显著提高无线网络的可靠性和数据速率。该项目的研究成果不仅对网络社区有用，而且对电力线研究人员、互联网服务提供商和互联网设备制造商也很有用。拟议的工作还可以在没有蜂窝和有线互联网服务的偏远农村地区提供互联网服务。如果成功，这将是第一个展示可扩展电力线通信技术的项目，该技术允许多个设备同时发送和接收数据。本计划的目标是演示电力线上的多用户多输入多输出（MU-MIMO）技术。信道空间独立性的初步观测表明，MU-MIMO是可行的。该项目将建立一个新的宽带耦合器，将软件定义无线电与电力线连接起来。它将描述电力线信道并研究其对空间独立性的影响。它将研究大功率电器在电力线上观察到的瞬态和噪声，以及它们对拟议技术的影响。随着用户数量的增加，它还将测试架构的可伸缩性。该项目将在家庭、办公室、学校和仓库等各种环境中进行实验。该项目有潜力在没有蜂窝和有线互联网服务的偏远农村地区提供互联网服务。该项目计划开发新的教学方法，以促进代表性不足的群体在本科阶段的参与，并制定一项中学暑期课程，向这些群体介绍无线技术。该奖项反映了美国国家科学基金会的法定使命，并通过使用基金会的知识价值和更广泛的影响审查标准进行评估，被认为值得支持。

This project exploits ubiquitous powerlines to enable high data rate communication by allowing multiple devices to send / receive data simultaneously; currently, only one device can send / receive data at a given time. This technology is attractive in that it leverages existing power line plant and can work with existing wireless access points to improve reliability, coverage and data rate. It has deep implications for existing internet technologies. It can be used as a backbone network for existing wireless access points to share coordination information, control and data to significantly improve wireless network reliability and data rate. The research outcome from this project is useful not only to the networking community, but also to powerline researchers, Internet service providers and Internet device manufacturers. The proposed work can also enable Internet service in remote rural areas where there is no cellular and cable internet service. If successful, it will be the first project to demonstrate a scalable powerline communication technology that allows multiple devices to send and receive data simultaneously.The goal of this project is to demonstrate multi-user multi-input multi-output (MU-MIMO) techniques on powerlines. Preliminary observations of the spatial independence of channels suggests that MU-MIMO is feasible. The project will build a new wideband coupler that will interface a software-defined radio with the powerline. It will characterize the powerline channel and study its impact on spatial independence. It will study the transients and noise observed on the powerline from high-power appliances, and their impact on the proposed techniques. It will also test the scalability of the architecture as the number of users increases. The project will perform experiments in a variety of environments such as homes, offices, schools and warehouses. This project has the potential to enable Internet service in remote rural areas where there is no cellular and cable internet service. The project plans to develop new pedagogical methods to enhance the participation of underrepresented groups at the undergraduate level, and a middle-school summer curriculum that introduces wireless technology to those groups.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.
