UHF Gen 2: The Definitive, Myth-Busting, Item-Level Solution
White Paper Older formats use relatively low frequencies; whereas a resurgence of interest in RFID has attended the use of Ultrahigh Frequencies (UHF). The answer is a resounding yes for the first time, and enabled... [14 Nov 2009]
Pharmaceutical Shifts Towards UHF RFID for Savings
White Paper At all of these levels there are benefits to be derived from RFID technologies, beginning with the effort to stem the influx of counterfeit drugs. The pharmaceutical industry in the United States dispensed more than $260... [12 Nov 2009]
UHF Gen 2: Deep and Wide, Near and Far
White Paper The key to this development is Impinj's patented (and patents pending) technologies for harnessing UHF's near field - that aspect of the radio wave that is particularly well-suited to close range, item-level... [12 Nov 2009]
What It Means, Why It Matters: UHF Gen 2 Interoperability
White Paper RFID hardware interoperability determines the ability of tags and readers manufactured by different suppliers to work interchangeably - to be, in fact, plug-and-play. This is critically important to end users, who simply... [12 Nov 2009]
Achieving Return on Investment Using RFID for Jewelry Tracking
White Paper Most RFID jewelry tracking applications deploy one of two frequencies: UHF (860 - 960 MHz) or HF (13.56 MHz). With the rapid development of new UHF chips however, this is just a... [30 Oct 2009]
Specific Absorption Rates in Muscle Tissues for UHF RFID Reader Systems
White Paper This paper describes the Specific Absorption Rates (SAR) of Radio Frequency (RF) energy in muscle tissues for UHF RFID reader systems. It is shown that the maximum SAR in muscle tissues for a... [15 Apr 2009]
A Novel Planar Microstrip Antenna Design for UHF RFID
White Paper Passive UHF RFID tags generally do not work well near metal or water. Microstrip antennas offer a potential solution, but suffer from manufacturing complexity because a need for via or some other... [15 Apr 2009]
Assessing and Optimizing the Range of UHF RFID to Enable Real-World Pervasive Computing Applications
White Paper However, while passive UHF RFID has many benefits over other RFID variants, reliable operation as the tag moves in the environment is inherently difficult to predict and can represent a... [15 Apr 2009]
A Low-Power AC/DC Rectifier for Passive UHF RFID Transponders
White Paper Besides, the design of a low-power rectifier for passive UHF RFID transponder, which is compatible with standard CMOS process and can be applied to the environment in which the distance from interrogator... [15 Apr 2009]
A Modular UHF Reader Frontend for a Flexible RFID Testbed
