The ORCA card (standing for One Regional Card for All) is a contactless, stored-value smart card system for public transit in the Puget Sound region of Washington, United States. The card is valid on most transit systems in the Seattle metropolitan area, including Sound Transit, local bus agencies, Washington State Ferries, the King County Water Taxi, and Kitsap Fast Ferries. It was laun.

We derive a theoretical formula for RCS of an RFID tag with a minimum scattering antenna and . This article walks through the basics and advanced principles related to how UHF RFID Passive tags communicate via backscatter. Before reading, it is important to know about the types of coupling and when each one is used.We derive a theoretical formula for RCS of an RFID tag with a minimum scattering antenna and describe an experimental measurement technique which involves using a network analyzer connected to an anechoic chamber with and without the tag.
This video will show you how RFID systems work in industrial applications to track transport equipment. RFID readers on rail lines and in shipping yards/ports keep track of container movements.
This paper proposes an optimal 4 Quadrature Amplitude Modulation (4QAM) backscatter scheme at 920 MHz, which can increase the throughput and simultaneously improve energy utilization. In this optimal scheme, the reflection coefficient modulus | Γ | .The accuracy of time-of-flight based ranging systems is fundamentally limited by the available bandwidth. This paper first analyzes the UHF RFID backscatter channel formed by convolution of the individual constituent channels. Passive and semipassive UHF RF identification (RFID) systems have traditionally been designed using scalar-valued differential radar cross section (DRCS) methods to model the backscattered signal from the tag.

This article presents the design and implementation of a passive, computational ultra high frequency (UHF) radio frequency identification (RFID) platform using vector backscatter modulation on the uplink (tag-to-reader). Backscatter radio has been extensively used in commercial radiofrequency identification (RFID) applications in sub-gigahertz bands to wirelessly transmit static identification codes with.UHF RFID backscatter channels is fundamentally limited by the available bandwidth and highly dependent on the channel characteristics. Comprehensive wideband channel measurements are presented and analyzed with respect to parameters which influence the potential ranging performance. The Cram´er Rao
