In this paper we present an innovative UHF-UWB Radio-Frequency IDentification (RFID) system adopting semi-passive tags, which is capable of overcoming several limitations of available systems while avoiding the use of active devices, ensuring both identification and real-time item localization. Implementation challenges are described, preliminary measurement results are shown and an example of the localization performance is presented

“…We then evaluate the simulation performance of the described receiver architecture in terms of localization error outage (LEO) [16]. A bi-dimensional reference scenario composed of a (10 × 10) m 2 room with four readers located at the corners is chosen, and tags are assumed to be static.…”

“…a backscatter reflection, requiring simulations to mix in motion models or employ statistical tricks to attempt to model a complex, indoor UWB backscatter channel [17]. D'Errico et al further explore how to design a hybrid system with a conventional RFID frontend for wakeup and energy harvesting [10]. The Slocalization design is independent of energy frontend and amenable to such a hybrid design.…”

Ultra wideband technology has shown great promise for providing high-quality location estimation, even in complex indoor multipath environments, but existing ultra wideband systems require tens to hundreds of milliwatts during operation. Backscatter communication has demonstrated the viability of astonishingly low-power tags, but has thus far been restricted to narrowband systems with low localization resolution. The challenge to combining these complimentary technologies is that they share a compounding limitation, constrained transmit power. Regulations limit ultra wideband transmissions to just -41.3 dBm/MHz, and a backscatter device can only reflect the power it receives. The solution is long-term integration of this limited power, lifting the initially imperceptible signal out of the noise. This integration only works while the target is stationary. However, stationary describes the vast majority of objects, especially lost ones. With this insight, we design Slocalization, a sub-microwatt, decimeter-accurate localization system that opens a new tradeoff space in localization systems and realizes an energy, size, and cost point that invites the localization of every thing. To evaluate this concept, we implement an energy-harvesting Slocalization tag and find that Slocalization can recover ultra wideband backscatter in under fifteen minutes across thirty meters of space and localize tags with a mean 3D Euclidean error of only 30 cm.

“…Localization with Gen-2 ultra-high frequency (UHF) RFIDs is based on received signal strength indicator (RSSI), phase (also at different operating frequencies), or angle-of-arrival (AOA) measurements [8]- [14]. The ultra-wideband (UWB) technology [15]- [20] has been recently proposed for new generation RFID systems as it provides high ranging accuracy even in harsh propagation environments [21]- [25]. UWBbased RFID systems rely on the exploitation of the backscatter modulation 1 and the measurement of the time-of-arrival (TOA) of the backscattered signals [26]- [28].…”

The order-of-arrival (OOA) of a stream of objects moving along a monitored direction is important for many decision operations in logistic and industrial applications. As an example, the dispatch of luggage in airports requires to determine their OOA at checkpoints; as another example, the automatic steering of items in supply chains requires to sort and identify them while moving on a conveyor belt. This paper establishes a general framework for determining the OOA of objects that are moving along a monitored direction via radiofrequency identification (RFID) systems. Three techniques for OOA tracking are proposed and developed for objects equipped with RFID tags possessing ranging capabilities. The benefits of the proposed techniques are experimentally validated based on measurements gathered with a RFID system operating in an indoor environment.
