Researchers at Ohio State University’s ElectroScience Laboratory (ESL) are designing "hovering" or suspended high-gain millimeter-wave antenna arrays that boost wireless signals and alleviate the crowded electromagnetic frequency spectrum.
By coupling the acoustic resonance of a small antenna with the electromagnetic wave, researchers at the Air Force Research Laboratory Materials and Manufacturing Directorate have succeeded in scaling antenna sizes down to 90 percent smaller than state-of-the art compact antennas.
This Qorvo article highlights the need for higher order modulation, carrier aggregation, and 4x4 MIMO technologies in the journey to faster download speeds, and how to add 1 Gbps front-end modules to smartphones.
Researchers in India have fabricated a new type of wearable antenna on polyester fabric that can be worn by military personnel to monitor their health status.
The first 5G smartphones could make their way to store shelves as early as next year, and 5G-connected cars could hit roads by 2020, according to major industry players who are shaping the fast-emerging 5G ecosystem.
The current Wi-Fi standard, 802.11ac, works very well in a home environment. However, as with previous Wi-Fi standards, it may reach its limits around 2022 when there could be up to 50 nodes in a home. The 802.11ax network is the next evolution in the IEEE 802.11 Wi-Fi standard and will become prevalent in very dense environments, such as urban apartment complexes, college campuses, concert venues, or sports stadiums, where many clients will access the internet over Wi-Fi. This article presents five key aspects of the new 802.11ax network and the next generation of Wi-Fi.
Nanoelectromechanical system (NEMS) antennas that resonate with acoustic waves, rather than with electromagnetic waves alone, could significantly reduce the size of electronic devices, according to a team of scientists at Northeastern University in Boston.
The population of adults 85 and older in the U.S. will roughly triple between 2015 and 2060, making it the fastest-growing age group over this time period. This has become a major concern for families taking care of seniors who will be living on their own. Qorvo’s Senior Lifestyle System has been tested and used for the last 15 years in assisted living communities in Europe to help seniors live more independently. Within a few weeks, this system learns the routine day-to-day activities of the senior resident, provides intelligent status updates in a dashboard app, and sends alerts to designated caregivers if something unexpected happens.
Layered two-dimensional materials that are as efficient, but thinner than, silicon semiconductors, could power future electronic circuits and devices, according to Stanford researchers.
Ghana says it has successfully refurbished and converted an old telecommunications antenna into a radio telescope, one of several radio-based antennas that will comprise the African Very Large Baseline Interferometer (VLBI) Network (AVN).
