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 ...
Using signal-to-noise measurements from a single commercial-grade L1 GPS receiver, it is possible to detect interference or jamming that is above the thermal noise floor and below a power that causes ...
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 ...
The implementation of a wireless LAN may seem easy at first. All you have to do is install a few access points, connect them to an Ethernet switch, and you’re ready to go. Right? Well, it’s not always ...
In my column last month (“Get Ready for ATSC 3.0, But Don’t Ignore 1.0”), I compared ATSC 1.0 and ATSC 3.0 reception. While it is being rolled out, ATSC 3.0 is likely to require similar antennas to ...
Delivering digital terrestrial broadcasting radio waves throughout the country requires the installation of a large number of relay broadcasting stations. STRL has ...
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 ...
