The IOTA Foundation is launching a free, more secure, and scalable alternative to Bitcoin and other cryptocurrencies. Unlike current cryptocurrencies, which rely on blockchain technology, the organization's namesake virtual currency features a "tangle" ledger system that could more appropriately harness the data-driven business transactions enabled by the Internet of Things.
DARPA’s Collaborative Operations in Denied Environment (CODE) program aims to extend the capability of the U.S. military’s existing unmanned aircraft systems (UASs) to conduct dynamic, long-distance engagements of highly mobile ground and maritime targets in contested or denied battlespaces.
At CES 2018 in Las Vegas, Qualcomm says it is adopting a comprehensive approach with 5G, including developing RF chips and modems to support the first 5G phones hitting store shelves by 2019.
Researchers at the National Institute of Standards and Technology (NIST) have demonstrated that quantum physics might enable communications and mapping in locations where GPS and ordinary cellphones and radios don’t work reliably or even at all, such as indoors, in urban canyons, underwater and underground.
Some connected things requiring global coverage and/or mobility will use cellular technologies, but most IoT devices will use noncellular technologies, sharing frequencies in unlicensed bands to communicate with each other and with IoT applications.
Until recently, Traveling Wave Tube Amplifier (TWTA) technology has been the only available option for pulsed field generation. AR now offers high-power solid state pulsed amplifiers at various frequency ranges and output power levels to meet several standards. This white paper presents some of the key features and benefits of AR’s new line of amplifiers, and how to generate high speed and accurate peak RF power measurement capabilities that are ideal for EMC testing, manufacturing testing/troubleshooting, amplifier design/development, and research.
This white paper describes the basic functionality of antennas. Starting with Hertz's Antenna model followed by a short introduction to the fundamentals of wave propagation, the important general characteristics of an antenna and its associated parameters are explained.
Time Difference Of Arrival (TDOA), also called multilateration, is a technique for RF emitter geolocation using three or more receivers with algorithms to locate a signal source from the different arrival times at the receivers. This article explains factors that can have an impact on overall TDOA accuracy.
To classify a signal in RF spectrum intelligence gathering, the user must recognize a specific pattern associated with the modulation. Additionally, to recognize a remarkable signal present in received data, the pattern must be distinguished from the noise. Pattern recognition is something that the human brain is good at, but it is more desirable to automate these applications for efficiency and to avoid errors cause by human fatigue.
