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 ...

However, there are some concerns that USB 3.0 on routers may be a source of signal interference for wireless devices. Let's look at the reality behind this fear, and also at what the industry and you ...

Bug Detectors are designed to identify hidden electronic surveillance equipment such as wireless cameras, microphones, and tracking transmitters. These devices scan for radio frequency activity and ...

Whether by carrier fault or signal-blocking materials within your home, poor mobile phone signal strength is frustrating, and may be downright infuriating after a strip of dropped calls. Whatever the ...

With many smartphones costing upwards of $1000 (and even budget phones costing several hundred dollars), most of us want to do all we can to protect our investment. A common way to do that is to buy a ...

Cellular signal boosters use big antennas to improve the coverage in your home, vehicle, or property. These are the top signal boosters for apartments and houses. I’m one of PCMag’s mobile writers.

NTT Corp. (NTT) and Okayama University have developed a solution to the increasing problem of IoT signal interference by creating a topological ultrasonic circuit. Claimed as the first of its kind, ...

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 ...
