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 ...

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.

Throughout the past several decades, GNSS has become one of the most significant technologies in modern engineering, supporting transportation, communications, finance, emergency response, and ...

Spirent Communications recently introduced a new GNSS and PNT simulation system, the PNT X, which brings together L-band, S-band, and alternative navigation signals, as well as Regional Military ...

As the number of higher-throughput applications grows, so does the need for a wider bandwidth and network coverage in wireless systems. Given limited spectrum allocation, wireless communication ...

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 ...
