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 ...

To enable mass deployment, fixed broadband wireless service providers are moving away from the first generation, line-of-sight (LOS) deployments toward next-generation deployments that require non-LOS ...

Unforeseen RF transmission impairments, such as cordless phones that use the 2.4GHz band, can cause frustration when deploying wireless LANs. In order to maintain happy users, it’s a good idea to ...

It has long been appreciated that FM reception is vulnerable to multipath propagation. The effect of an echo for instance a reflection off a building is to create high-order harmonic and ...

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 ...
