Traficom said late last week it had received "numerous occurrence reports" of GPS signal interference along the border. [Courtesy: Finnair] GPS signal interference has been reported along Finland’s ...

A signal detected by a Chinese telescope and originally reported as possible evidence of extraterrestrial intelligence is almost certainly due to human factors, one of the researchers on the project ...

Satellites depend on radio frequency spectrum to communicate with each other and with ground stations on Earth, but spectrum is a finite resource that’s prone to interference — an issue that’s only ...

Space used to be a mostly quiet backdrop for rockets and research. Now it is crowded with thousands of internet satellites that are not only brightening the night sky but also sending out unexpected ...

Multipath interference disrupts wireless signals, causing issues like TV ghosting and fading. Now, researchers have developed a passive metasurface that overcomes traditional filtering limits. Using a ...

This video presents a study in which researchers developed a passive metasurface that uses a time-varying interlocking mechanism with metal-oxide-semiconductor field-effect transistors to selectively ...
