CAREER: Long-Range 5.8 GHz Backscatter RF Tag SystemsProposal No. ECS-0546955PI: Prof. Gregory D. DurginAbstract----------This CAREER proposal focuses on the design of a novel system for reading radio-frequency (RF) backscatter tags at 5.8 GHz. Backscatter radio is an incredibly promising technology for the wireless exchange of sensor data, identification information, and digital content using passive, low-cost devices. Todays state-of-the-art RF tags struggle to exchange information with tags and readers separated by a distance of even 1m. The proposed basic research will enable a separation distance in excess of 100m, pushing the technology of RF backscatter tags into entirely new application spaces: internal glucose monitoring for diabetics, contactless data retrieval from memory sticks, hull corrosion sensing for aircraft, wireless barcodes, and countless other conceivable applications.Intellectual Merit: The technical goal of the proposed project is to design, construct, and characterize a 5.8 GHz RF backscatter tag system using multiple antennas at both reader and tag. A basic 5.8 GHz backscatter measurement testbed will be constructed. We will add incremental complexity to the system, designing multiple antennas, modulation, and multiple access schemes, until a full 4 x 2 x 4 (4 transmitter antennas, 2 RF tag antennas, and 4 receiver antennas) system is complete. We will also characterize diversity gains, spatio-temporal channel characteristics, and on-object tag degradations.Broader Impacts: This project is a crucial part in fulfilling the PIs career goal of establishing a world-class research program at Georgia Tech that brings industry, government, and international academic institutions together for the invention and study of cutting-edge, multi-disciplinary radio technologies. RF backscatter tags are the backbone of the fledgling program. The PI will incorporate this research into applied RF/electromagnetics courses at Georgia Tech. As part of the proposed project, the PI and the student radio organization WREK also plan to develop and broadcast 5 audio programs that will educate general audiences across metropolitan Atlanta about new radio technology.

职业生涯：远程5.8 GHz反向散射射频标签系统建议编号：ECS-0546955PI：格雷戈里·D·杜尔金教授摘要-这份职业建议书专注于设计一种新型的系统，用于读取5.8 GHz的射频(RF)反向散射标签。后向散射无线电是一种非常有前途的技术，可以使用无源、低成本的设备来无线交换传感器数据、身份信息和数字内容。如今，最先进的射频标签很难与相隔1米的标签和阅读器交换信息。拟议的基础研究将使间隔距离超过100米，将射频反向散射标签技术推向全新的应用领域：糖尿病患者的内部血糖监测、从记忆棒中非接触式数据检索、飞机机身腐蚀传感、无线条形码和无数其他可以想到的应用。智能优点：拟议项目的技术目标是设计、建造和表征5.8 GHz射频反向散射标签系统，该系统在读取器和标签处都使用多个天线。将搭建一个5.8 GHz的基础后向散射测量实验台。我们将增加系统的复杂性，设计多个天线、调制和多路接入方案，直到完整的4 x 2 x 4(4个发射器天线、2个RF标签天线和4个接收器天线)系统完成。我们还将对分集增益、时空信道特性和对象标签退化进行表征。广泛影响：该项目是实现个人信息系统职业目标的关键部分，该目标是在佐治亚理工学院建立一个世界级的研究计划，将行业、政府和国际学术机构聚集在一起，发明和研究尖端的、多学科的无线电技术。射频后向散射标签是这个羽翼未丰的计划的支柱。国际和平研究所将把这项研究纳入佐治亚理工学院的应用射频/电磁学课程。作为拟议项目的一部分，PI和学生广播组织WREK还计划开发和广播5个音频节目，以教育亚特兰大全市的普通受众了解新的无线电技术。
