rfid localization review
A novel system developed at MIT uses RFID tags to help robots home in on moving objects with unprecedented speed and accuracy. The system could enable greater collaboration and precision by robots working on packaging and assembly, and by swarms of drones carrying out search-and-rescue missions.The location accuracy of an active RTLS is usually within 3 meters. An ultra-wideband RTLS is able to achieve greater location accuracy over long distances by using different frequencies to mitigate something called multipath, where signals bounce off surfaces and reach the reader at different times, making it hard to calculate distance precisely.In this paper we show how to exploit the phase difference between two or more receiving antennas to compute accurate localization. Phase difference based localization has better accuracy, robustness and sensitivity when integrated with other measurements compared to the currently popular technique of localization using received signal strength.The proposed localisation system can operate in a realistically radio-noisy indoor environment, enables design-space trade-offs, is highly extensible, and provides use-case-driven average accuracy as low as 0.15 metres.
In this paper, we propose an innovative approach based on the multiple input single output (MISO) protocol to improve the accuracy of a low-cost RFID localization system. Whereas most traditional systems use a single tag for localization, the proposed architecture encourages the use of a group of RFID tags named as a constellation. Many applications will benefit from millimeter level (mm-level) localization accuracy. For example, false positive reads will be avoided by setting the intended reading zone beforehand. If the RFID tag is within the area, the RFID reader will record and report events related to this tracked tag.Active tags can tell you that an item is within 300 feet of a reader, but there are also active RFID real-time location systems (RTLS) that can triangulate on a tag and tell you its location to within 10 feet.
