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 ...

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 ...

Presented at ION GNSS+, September 2016. The robustness of a GNSS receiver against interferences can be increased significantly by using an adaptive notch filter, which estimates the instantaneous ...

Multipath is a condition that arises when a transmitted signal undergoes reflection from various obstacles in the environment. This is a new and promising technology in the field of wireless and ...

High-spectral-efficiency quadrature amplitude modulation (QAM) is used over many communications media such as twisted pair, coaxial cable, fiber optics and radio to carry high-speed digital ...

Littleton, MA. octoScope Inc. has introduced iGen, the first compact, easy-to-integrate interference generator capable of generating Wi-Fi traffic and other common types of interference, enabling ...

Delivering digital terrestrial broadcasting radio waves throughout the country requires the installation of a large number of relay broadcasting stations. STRL has ...

For something we rely on so heavily, GPS is pretty rubbish. In the open, it is accurate to within a few metres, but in built-up areas it frequently cannot even locate the correct city block. Now a new ...

Three's company: interference patterns for one to four slits (expand for full image) A group of physicists in Austria has directed a beam of large molecules at a series of extremely narrow slits 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 ...
