Like most who grew up in the middle of the 20th century, I have fond memories of my family crowded around a snowy, rabbit-eared tube to watch Bonanza and The Ed Sullivan Show on weekend nights. Back then, broadcast television was king. It was all we had, and we were crazy about it.

“Great Capacity!” “Less Latency!”—How Wi-Fi 7 Achieves Both

New features will roll out in some devices by the end of 2022

New generations of Wi-Fi have sprung onto the scene at a rapid pace in recent years. After a storied five-year presence, Wi-Fi 5 was usurped in 2019 by Wi-Fi 6, only for the latter to be toppled a year later in 2020 by an intermediate generation, Wi-Fi 6E. And now, just a couple years later, we’re on the verge of Wi-Fi 7.

Wi-Fi 7 (the official IEEE standard is 802.11be) may only give Wi-Fi 6 a scant few years in the spotlight, but it’s not just an upgrade for the sake of an upgrade. Several new technologies—and some that debuted in Wi-Fi 6E but haven’t entirely yet come into their own—will allow Wi-Fi 7 routers and devices to make full use of an entirely new band of spectrum at 6 gigahertz. This spectrum—first tapped into with Wi-Fi 6E—adds a third wireless band alongside the more familiar 2.4-GHz and 5-GHz bands.

Reduce EMI and EMC Issues with Engineering Simulation Software

Save time and money all while delivering accurate and reliable results

1 min read

Electronic components and systems exist today in nearly all consumer and industrial products. A major design consideration in all electronics is electromagnetic interference (EMI) and compatibility (EMC). EMI and EMC issues are complex. They can be hard to detect and can be taxing to a design. With the use of engineering simulation software, design engineers can mitigate issues before entering the prototype testing phase. Avoiding the test-retest cycle with simulation can help save time and money all while delivering robust and reliable products.
