CAREER: Long-Range 5.8 GHz Backscatter RF Tag Systems

职业生涯：长距离5.8 GHz反向散射射频标签系统提案编号ECS-0546955 PI：Prof. Gregory D. Durgin摘要-这个CAREER提案的重点是设计一个新颖的系统，用于在5.8 GHz下阅读射频（RF）反向散射标签。 反向散射无线电是一种非常有前途的技术，用于使用无源低成本设备进行传感器数据、识别信息和数字内容的无线交换。 当今最先进的射频标签难以与标签和阅读器交换信息，即使标签和阅读器之间的距离只有1米。 该基础研究计划将实现超过100米的分离距离，将射频背散射标签技术推向全新的应用领域：糖尿病患者的内部葡萄糖监测、记忆棒的非接触式数据检索、飞机船体腐蚀传感、无线条形码以及无数其他可能的应用。拟议项目的技术目标是设计，建造和表征一个5.8 GHz的RF后向散射标签系统，在阅读器和标签使用多个天线。 将构建一个基本的5.8 GHz后向散射测量试验台。 我们将增加系统的复杂性，设计多天线，调制和多址方案，直到一个完整的4 x 2 x 4（4个发射天线，2个RF标签天线和4个接收天线）系统完成。 我们还将表征多样性增益，时空信道特性，和对对象的标签degradations.Broader影响：这个项目是在实现建立一个世界级的研究计划在格鲁吉亚技术，使工业，政府和国际学术机构一起发明和研究的尖端，多学科的无线电技术的PI职业生涯的目标的一个至关重要的部分。 RF反向散射标签是这个新兴项目的支柱。 PI将把这项研究纳入格鲁吉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和学生无线电组织WREK还计划开发和广播5个音频节目，将教育亚特兰大大都市的普通观众了解新的无线电技术。

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.
