该演示展示了RFind，这是一个通过超宽带仿真实现细粒度RFID定位的系统。RFind通过测量飞行时间来操作，即，信号从天线传输到RFID标签的时间。为此，它在当今的窄带RFID上模拟超宽带宽，而无需对标签进行任何硬件修改。然后，它使用大的仿真带宽来估计飞行时间和定位RFID。与过去的RFID定位方案相比，RFind可以在多路径丰富的环境中运行，无需参考标签，也无需标签或天线运动。该演示将允许用户将RFID标记的对象移动到视线，非视线和多路径丰富设置中的任何位置，并检查系统是否可以准确定位对象。
This demo presents RFind, a system that enables fine-grained RFID localization via ultra-wideband emulation. RFind operates by measuring the time-of-flight -- i.e., the time it takes the signal to travel from an antenna to an RFID tag. To do so, it emulates an ultra-wide bandwidth on today's narrowband RFIDs without requiring any hardware modification to the tags. It then uses the large emulated bandwidth to estimate the time-of-flight and localize RFIDs. In contrast to past RFID localization proposals, RFind can operate in multipath-rich environments without reference tags and without requiring tag or antenna motion. The demo will allow users to move RFID-tagged objects to any location in line-of-sight, non-line-of-sight, and multi-path rich settings and check that the system can accurately localize the objects.
