A new breakthrough in wireless technology could dramatically boost internet speeds while cutting energy use—by switching from radio waves to light. Researchers have developed a tiny chip packed with ...

For many travelers, the request to switch their devices to airplane mode before takeoff feels like little more than an ...

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 ...

Weak iPhone signal strength can be frustrating, leading to dropped calls, slow data speeds, and overall poor performance. However, by implementing a few simple strategies, you can significantly ...

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.

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 ...

Even in the best designs, noise and interference sneak in to reduce the signal-to-noise ratio (SNR), obscure desired signals, and impair measurement accuracy and repeatability. Digitizing instruments ...

Researchers have demonstrated a compact optical wireless transmitter that delivers very high data rates while consuming ...

Explore the U.S. wireless communications industry and how real-time video transmission is evolving through faster networks, ...

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 ...
