“…Researchers validate simulation results with measurement data generated by off-the-shelf RFID components [41,53] or a controlled environment composed of prototypes, commercially available RFID components and measurement equipment [54]. Moreover, several groups reported on measurement results by off-the-shelf RFID equipment: Pentilla et al [14] study the impact of fast-moving objects in RFID systems and Bertocco et al [55] provide benchmarks on multi-tag and long-range system performance, while Nikitin et al [56] show experimental tag localization results.…”

“…Several powerful RFID simulation environments have been reported recently: Typical questions of research here include the evaluation of a single component of the RFID equipment, like RFID tags [35][36][37], readers [38], or antennas and analog parts [39,40], physical and logical layer simulation and its impact on the performance of the RFID system in different frequency domains [36,[41][42][43][44]. Simulators further call attention to multi-tag and multireader environments [45][46][47][48][49][50][51][52].…”

Today's RFID systems exhibit relatively little functionality, while future systems and ubiquitous computing applications require an ample set of general purpose features, like wide communication ranges, high data rates, high reliability, and many more. In order to meet these high-performance goals, several challenges in state of the art RFID systems need to be managed: (1) the compatibility of RFID equipment, working according to different standards in various frequency domains, (2) the thorough understanding of the performance impact of physical layer system parameters, (3) the venture of novel wireless technologies in the context of RFID, and finally, (4) to deal with the increased complexity of high-performance RFID systems. Therefore, designers desire a highly configurable, flexible, and high-performance RFID environment to experimentally explore the underlying physical conditions and to evaluate novel RFID technologies and designs. This paper introduces the concept of rapid prototyping in RFID and provides a survey of system simulators, demonstrators, and rapid prototyping environments. A guideline for the setup for such a rapid prototyping system applicable for RFID is presented, and its implementation is demonstrated. Finally, some exemplary measurements carried out with this rapid prototyping system are presented.

“…Because the fine-grained behavior of current systems is poorly understood, existing analytical [9,12] and simulation studies [6] of RFID are based on idealized versions of both the Gen 2 standard and RFID device performance. Though tools for detailed evaluation of RFID readers and tags exist, they are expensive (>$50K) as they are built using high-end equipment such as vector signal analyzers and proprietary software [8,1].…”

We have developed a low cost software radio based platform for monitoring EPC Gen 2 RFID traffic. The Gen 2 standard allows for a range of PHY layer configurations and does not specify exactly how to compose protocol messages to inventory tags. This has made it difficult to know how well the standard works, and how it is implemented in practice. Our platform provides much needed visibility into Gen 2 systems by capturing reader transmissions using the USRP2 and decoding them in real-time using software we have developed and released to the public. In essence, our platform delivers much of the functionality of expensive (> $50,000) conformance testing products, with greater extensibility at a small fraction of the cost. In this paper, we present the design and implementation of the platform and evaluate its effectiveness, showing that it has better than 99% accuracy up to 3 meters. We then use the platform to study a commercial RFID reader, showing how the Gen 2 standard is realized, and indicate avenues for research at both the PHY and MAC layers.

“…As spectral masks and permitted frequency bands are quite strict ( [2], [6]), these simulation architectures only feature narrowband models. Furthermore, just the simulator presented in [4] supports fading channels. Although a narrowband assumption is an obvious choice for the analysis of today's systems, next generation RFID might take advantage of the benefits of wideband and multiband systems in multipath environments.…”

A chip manufacturing process requires extensive support of CAD-tools in order to predict the behavior of the embedded circuitry and to ensure the intended system functionality. Past experience shows that the overall performance of UHF RFID systems is mainly limited by multipath propagation and detuning. In this context, system-level simulations are vital to assess the overall performance and improve the embedded circuit. We present a simulator framework capable of handling chiplevel tag models, fading MIMO radio channels, and interrogator building blocks on signal level. It is based on highly flexible behavioral tag-models instead of highly accurate but static ASIC models. In contrast to other UHF RFID simulators, it is explicitly designed to handle wideband signals, fading channels, nonlinearities, and detuning effects. The simulator is currently used to develop and evaluate the performance of ranging and realtime channel estimation systems. The presented results emphasize the feasibility of our framework in the evaluation of a range estimation approach between a standard UHF RFID transponder and an interrogator.
