“…To address this issue, we propose an antenna and tag selection algorithm which chooses the minimum amount of antennas and tags to achieve acceptable recognition accuracy. Further, we could use more optimized hardware solutions for mobile applications such as [24] for system implementation. Second, the number of tags can be read by a RFID reader during a single scan is limited.…”

“…This is because the device currently used is not optimized for our usage scenario. With the development of lowpower, compact RFID readers [24], the power consumption of the RFID reader will not be a significant issue in the future. Further, as suggested in Section 5.4.2, our radiobased approach favors the most discriminative transmission power level which is often relatively lower than data-based approaches [27].…”

“…As a result, in this work, we use Commercial Off-the-Shelf (COTS) RFID readers with RSS sensing ability instead of more sophisticated devices with CSI and signal phase capturing abilities to provide a lower-cost and more accessible solution. Recent technical trends show that low-cost, lowpower RFID readers are becoming commonly available on smartphones [24], making it promising for our work to be widely adopted in the future.…”

Elderly care is one of the many applications supported by real-time activity recognition systems. Traditional approaches use cameras, body sensor networks, or radio patterns from various sources for activity recognition. However, these approaches are limited due to ease-of-use, coverage, or privacy preserving issues. In this paper, we present a novel wearable Radio Frequency Identification (RFID) system aims at providing an easy-to-use solution with high detection coverage. Our system uses passive tags which are maintenance-free and can be embedded into the clothes to reduce the wearing and maintenance efforts. A small RFID reader is also worn on the user's body to extend the detection coverage as the user moves. We exploit RFID radio patterns and extract both spatial and temporal features to characterize various activities. We also address the issues of false negative of tag readings and tag/antenna calibration, and design a fast online recognition system. Antenna and tag selection is done automatically to explore the minimum number of devices required to achieve target accuracy. We develop a prototype system which consists of a wearable RFID system and a smartphone to demonstrate the working principles, and conduct experimental studies with four subjects over two weeks. The results show that our system achieves a high recognition accuracy of 93.6 percent with a latency of 5 seconds. Additionally, we show that the system only requires two antennas and four tagged body parts to achieve a high recognition accuracy of 85 percent.

“…It has 20 dBm output power with dimensions of 90 times 35 times 5 mm. Peng et al [5] presented a low-cost, low-power UHF RFID reader IC for mobile applications, which has 0.18 mu m CMOS technology and area of 14 mm 2 , consuming 471 mW. A fully integrated single-chip RFID reader developed using the 0.18 mu m CMOS process was also presented in the literature [6].…”

A new low-power, low-cost ultrahigh-frequency (UHF) radio frequency identification (RFID) reader module for short range low/mid-powered applications is presented in this paper. AS3993 is used as the reader IC, which integrates all building blocks including an analog front-end, a microcontroller unit interface, a voltage-controlled oscillator, and a phase-locked loop in a 48-pin QFN (7 × 7 × 0.9 mm) package. It has a new architecture for lowering the power consumption with a DC supply of 2.7 V and a current of 65 mA, and improved-90 dBm sensitivity. A power amplifier with medium power and high efficiency is also integrated to fulfill the function of the UHF RFID reader module. The reader module fully supports EPC Class 1 Gen2 ISO 18000-6C protocol and ISO29143 air interface for mobile RFID. With the use of the AS3993 reader IC it is possible to reduce the total cost. This paper describes all the hardware and software designs and experimental results of the designed system. The measurement results indicate that the set output power value in the chip is achieved quite successfully.
