RFID Detector Card

RFID detection
Design firm Montie Design has developed an innovative radio frequency identification (RFID) detector card for sensing signals in domestic and international markets. ...

... "Small enough to fit into a shirt pocket or clip to an ID badge, Montie Design’s product enables users and installers to detect whether an RFID reader is actually sending out a signal. Installers or users need simply move the RFID detector card towards the RFID reader antenna; if the RFID reader antenna is actively radiating a signal, the center of the card will activate a bright blue led light. Depending on the antenna and the power level radiated by the RFID system, the card will illuminate as far as two feet away from the antenna. " ...

High-Scalability RFID Architecture

Mojix introduces European version of the Mojix STAR system, its UHF passive RFID solution for high-scalability. The system delivers significant improvements in reader sensitivity, extended read range, and additional coverage. ...

... "Functioning as a single network element at the enterprise edge, a Mojix STAR system consists of one or more Mojix STAR Receivers each managing up to 512 low-cost Mojix eNode transmitters, which are oriented to define the system's potentially huge, three dimensional coverage area. Mojix eNode transmitters provide energy to all passive RFID tags within their specified interrogation spaces. The centralized, high-sensitivity Mojix STAR receiver processes the resulting tag signals from across the system's 25,000 sq meter coverage area, including non line-of-sight tag signals. This unprecedented receive sensitivity is the result of Mojix’s use of advanced digital signal processing, phased array receiver, digital beam forming and digital packet radio to detect the faintest signals across large distances in noisy RF environments. " ...

RFID Transponder, Inlay Perform in Industrial Environment

Texas Instruments introduces the 12 mm Multi-Usage Wedge Transponder and 24 mm LF Circular Inlay to deliver improved performance in highly metallic and harsh industrial environments. ...

TI RFID Transponder

... "The 12 mm Multi-Usage Wedge Transponder offers improvements in chip circuitry that enable direct-on-metal mounting. The 24 mm LF Circular Inlay, manufactured using TI's patented tuning process, provides improved consistency in read and write performance in applications such as waste management and industrial production. The tags incorporate a number of TI's patented RFID technology and quality innovations including half-duplex (HDX) radio communication. HDX boosts read range by 50 percent compared with full-duplex (FDX) LF and offers a stronger RF signal because the HDX reader shuts down during the HDX tag's response. This allows the HDX reader to concentrate on receiving the signal thereby obtaining an accurate read as compared to FDX. In FDX systems, the reader signal remains on and may create RF interference as it attempts to read the FDX tag. HDX also features frequency shift keying technology which makes TI's tags more immune to electromagnetic interference (EMI) and other ambient environmental noise, allowing the reader to effectively read and differentiate tags that are close together. " ...

RFID Test Measurement

New test method enables rapid testing of multiple RFID tags, so that new antenna designs can be evaluated and commercialized. Research was conducted at Georgia Institute of Technology. ...

... "Each antenna signal can then be separated from the others, allowing his team to simultaneously measure the signals from multiple tags. Their experiments have shown they can measure the power strength and phase of up to 256 antennas in the field of view ... " ...
