South Korean telecommunications operator SK Telecom, partnered with Ericsson, has successfully demonstrated new “Elastic Cell” technology capable of improving data transfer speed up to 50 percent. This test could potentially speed up the development and release of 5G technology. “Elastic Cell,” also known as “Flexible Cell,” technology allows two-way communication between … [Read more...]
No-Power Wi-Fi Connectivity May Boost Internet of Things
Researchers at the University of Washington have developed a communication system that uses radio frequency signals and repurposes existing Wi-FI infrastructure to supply power and provide Internet connectivity, respectively, to battery-free devices. Known as Wi-Fi backscatter, this technology is the first of its kind capable of connecting battery-free devices to Wi-Fi … [Read more...]
Raleigh Lab to Offer EMC Testing and Wireless Certifications
ACS, Inc. a provider of regulatory compliance and product development testing services, announced today its new test lab in Raleigh, NC. The announcement was made during the IEEE 2014 International Symposium on Electromagnetic Compatibility. With labs in Atlanta, as well as Melbourne and Boca Raton, Florida, ACS is opening the Raleigh location in response to growing demand … [Read more...]
Wireless Power Transfer Employs Mini Receivers for Greater Efficiency
Scientists in Korea have developed a new wireless power transfer (WPT) technique using miniaturized receivers that enables more efficient wireless power transfer at greater distances than ever before. WPTuses overlapping magnetic fields, rather than wires, to transmit electric power. This technology is believed to have wide range of potential uses, from wireless cell phone … [Read more...]
Software Release Includes New Commercial Radio System and Digital Noise Signal Definitions
Delcross Technologies has announced the release of the Electromagnetic Interference Toolkit (EMIT) version 3.4 software offering an array of new features such as 13 new pre-defined transceiver, receiver and transmitter definitions for commercial radio systems and the ability to define noise sources for receiver desense analysis applications. Designed to address RF cosite … [Read more...]
USB 3.1 Receiver Test Set Verifies ASIC and Chipset USB 3.1 Receiver Ports
Agilent Technologies has announced the Agilent USB 3.1 receiver test set for use by design and test engineers in the semiconductor and computer industry to accurately characterize and verify USB 3.1 receiver ports in ASICs and chipsets. Released by the USB Implementers Forum in 2013 and expected to appear in products in 2014, the USB 3.1 specification more than doubles … [Read more...]
Researchers Develop ‘Snake-Like’ Flexible Metamaterial Absorber
Korean researchers have developed a flexible “snake-shaped” metamaterial absorber with the ability to suppress electromagnetic radiation. Scientists have studied metamaterials since the late 19th century, when artificial dielectrics were developed just after World War II. These artificial materials are specially engineered to affect electromagnetic radiation, sound or seismic … [Read more...]
Lasers Could Replace Quartz in Oscillators
Researchers at the California Institute of Technology have a developed a new method that uses a pair of laser beams, instead of a quartz crystal, to tune oscillators. The achievement could provide a better frequency reference to future consumer electronics and high-end navigation and radar systems. Present in nearly all electronic devices, oscillators are electronic circuits … [Read more...]
Researchers Boost Connectivity of Musical Wi-Fi Gloves
Scientists from the University of Bristol and the University of the West of England (UWE Bristol) have improved the performance of a pair of musical Wi-Fi gloves worn by popstar Imogen Heap. Used during Heap’s experimental live music performances to control both music and visuals with a series of gestures, the so-called Mi.Mu glove system must be robust enough to cope with … [Read more...]
Vancouver Café Blocks Wireless Signals
A new pop-up café in Vancouver, Canada is offering patrons a temporary escape from digital communication. Julien Thomas, a Vancouver construction worker and social artist, is opening The Faraday Café in Vancouver’s Chinatown with assistance from Hughes Condon Marler Architects. The café, which will be open July 2-16, is named after the Faraday cage, an enclosure made of a … [Read more...]
