A Kent, Wash. family plans to file a complaint with the Federal Communications Commission after hearing a profanity-laced conversation between truck drivers over a pair of Disney Princess Royal Walkie-Talkies purchased for their nine-year-old child. "We picked up some things that she shouldn't be hearing, or any child should … [Read more...]
High Current Shielded Power Inductors Available in Low DCR and High Isat Versions
Magnetic component supplier Coilcraft’s new SER80xx series high current shielded power inductors are offered in two versions—one providing exceptionally low DC resistance and the other offering saturation current ratings up to 53 Amps—making them ideal for a broad range of applications. Designed for applications with high average current (up to 13 A rms), the low DCR version … [Read more...]
Researchers Achieve New Wireless Transmission World Record
Researchers in Germany have reportedly set a new world record for wireless data transmission using a combination of photonic and electronic technologies. In a successful experiment at the Karlsruhe Institute of Technology, researchers were able to transmit 100 Gbs of data per second at a frequency of 237.5 GHz over a distance of 20 meters. Previous attempts have yielded rates … [Read more...]
Technology Prevents Dropped Calls in Disaster Situations
A new solution created by a University of British Columbia graduate student could prevent dropped calls and text messages in disaster situations by using television and radio channels to transmit cellular signals when telecommunication systems are overloaded. Because wireless towers are designed to handle a specific amount of call volume, a sudden or drastic increase in the … [Read more...]
Scientists Harness Power of Lightning to Charge Mobile Phone
A collaborative effort between the University of Southhampton, UK and smartphone manufacturer Nokia has yielded new proof-of-concept research on harnessing the power of lightning to charge electronic devices. At the university’s Tony Davies High Voltage Laboratory—one of the world’s leading high voltage laboratories—researchers successfully used energy similar to that of a … [Read more...]
Interference-Cancelling Technology May Ease Spectrum Congestion
A small startup company is testing a new technology that may enable mobile devices to simultaneously transmit and receive data on a single frequency. Founded by a group of Stanford University researchers, who in 2011 developed the first wireless radios capable of sending and receiving signals at the same time, California-based Kumu Networks Inc. believes its new technology … [Read more...]
Technology Allows Data Transfer through Metal Shielding
British engineers have reportedly discovered a way to bypass the Faraday cage effect that prevents the entry or escape of an electromagnetic wave through a metallic enclosure. According to a statement released by developer The Technology Partnership (TTP), new patent-pending Fluxor technology creates a “window” for electromagnetic transmission of power and data by applying a … [Read more...]
New Device Manipulates Millimeter Waves for Smaller Short-Distance Communication Systems
Researchers in Singapore have created a device capable of manipulating radio frequency signals that could lead to the development of smaller short-distance communication systems. Known as a subharmonic passive mixer, the device, built by Rui Li and her colleagues at the A*STAR Institute of Microelectronics, can convert millimeter waves from one wavelength to another. … [Read more...]
FAA Panel Advises Lifting Flight Restrictions on Electronics
A Federal Aviation Administration advisory committee tasked with investigating flight restrictions on personal electronic devices has concluded that most electronics, including those connected to onboard Wi-Fi, can be safely used during all portions of flight on most U.S. passenger aircraft. Established last year, the 28-member panel is comprised of representatives from the … [Read more...]
Radio Test System for Evaluation of Military and Software-Defined Radios
Aeroflex Inc., a provider of high performance microelectronic components and test and measurement equipment, has released the new Aeroflex 7215 Configurable Automated Test Set, a radio test system designed for production and depot-level testing of military and software-defined radios (SDR). According to the company, the new 7215 radio test system includes a high resolution … [Read more...]
