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 ...

The ubiquitous nerd in khaki pants and glasses makes it look so easy ” a seamless network of nationwide wireless access, a utopia of coverage where dropped calls are but a bad memory. Reality, as any ...

The testing of any new wireless receiver design usually requires conventional test instruments such as a vector signal generator and appropriate output instruments like a scope, vector signal analyzer ...

Interoperable multipath hemispherical map (MHM) using overlap-frequency signals across constellations. The top panel shows the flowchart for modelling and correcting multipath in interoperable MHM.

In my column last month (“Get Ready for ATSC 3.0, But Don’t Ignore 1.0”), I compared ATSC 1.0 and ATSC 3.0 reception. While it is being rolled out, ATSC 3.0 is likely to require similar antennas to ...

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 ...
