New software from Tenna Systems maps out the interference landscape by assembling telemetry data from existing radios, and allows jammers to be avoided — or targeted.

Abstract: The frequency dithering techniques (FDT) to attenuate electromagnetic interference (EMI) are widely researched in the literature. However, the existing FDTs cannot be applied to resonant ...

Turn coaxial cable into a DIY TV antenna in minutes. Make a few cuts, bend a wire, then run a channel scan to pick up free over-the-air broadcasts.

The breakthrough, detailed in Nature Photonics, centers on a fundamental problem facing 6G: how to efficiently transmit and receive data at terahertz frequencies. These frequencies, which ...

One type of friction can waste energy even when two perfectly smooth surfaces move against each other, but researchers are ...

Abstract: The distance of direct phone-to-satellite communication is significantly greater than that of cellular communication. The long distance leads to a high path loss, where a high-gain mobile ...

Vascular cognitive impairment (VCI), a cognitive disorder arising from cerebrovascular pathology, currently lacks effective targeted therapies. Dysfunction of the blood–brain barrier (BBB) represents ...

ESA fired a ‘non-explosive actuator’ in stuck bracket of the ESA JUICE spacecraft's RIME antenna to jar in loose. Mission controllers have been trouble shooting the antenna deployment for 3 weeks.
