Radio frequency identification (RFID)

Computers and Security, 2006
First conceived in 1948, Radio Frequency Identification (RFID) has taken many years for the technology to mature to the point where it is sufficiently affordable and reliable for widespread use. From Electronic Article Surveillance (EAS) for article (mainly clothing) security to more sophisticated uses, RFID is seen by some as the inevitable ...

Measurements at Radio Frequencies

Transactions of the American Institute of Electrical Engineers, 1940
IT IS interesting to recall that this art is less thana century old1 and that the early experimenters actually worked in the frequency range now called “hyper frequencies.”

Radio Frequency Fingerprinting on the Edge

IEEE Transactions on Mobile Computing, 2022
Deep learning methods have been very successful at radio frequency fingerprinting tasks, predicting the identity of transmitting devices with high accuracy. We study radio frequency fingerprinting deployments at resource-constrained edge devices.

Vulnerabilities of radio frequencies

2015 12th International Conference on Fuzzy Systems and Knowledge Discovery (FSKD), 2015
Despite current advancements in today's technologies, radio frequencies are still unprotected and continues to be an achilles heel of technology. A simple telephonic radio frequency (RF) can be intercepted with the use of a baby monitor. Many don't seem to understand the risks involved regarding with radio frequencies.

Radio Link Frequency Assignment

Constraints, 1999
The problem of radio frequency assignment is to provide communication channels from limited spectral resources whilst keeping to a minimum the interference suffered by those whishing to communicate in a given radio communication network. This problem is a combinatorial (NP-hard) optimization problem.

Photonic radio frequency phase-shift amplification by radio frequency interferometry

Optics Letters, 2015
We present a new technique for radio frequency (RF) phase-shift amplification based on RF interferometry and demonstrate it in an optical system. A striking feature of this amplifier is that the input phase noise is not amplified together with the input phase signal, so the phase sensitivity improves with higher phase amplification.

Radio Frequencies: Policy and Management

IEEE Transactions on Geoscience and Remote Sensing, 2013
The electromagnetic spectrum is a valued shared resource. Its scientific use allows us to learn about our universe, measure and monitor our planet, and communicate scientific data. The use of the spectrum is managed by national, regional, and global regulatory frameworks.

Radio frequency identification prototyping

ACM Transactions on Design Automation of Electronic Systems, 2008
While RFID is starting to become a ubiquitious technology, the variation between different RFID systems still remains high. This paper presents several prototyping environments for different components of radio frequency identification (RFID) tags to demonstrate how many of these components can be standardized for many different purposes.

Conductimetric Analysis at Radio-Frequency

Journal of Scientific Instruments, 1947
After referring to difficulties encountered when using standard conductivity cells, a brief reference is made to that part of the author's previous work on the measurement of electrolytic resistance which is essential to the present paper. Two new radio-frequency current arrangements for titration are described in both of which a length of Pyrex glass ...
