Sniff Wi-Fi

Two pieces of important news hit the wire recently: the 6 GHz band was approved for Wi-Fi, and alcohol sales have skyrocketed .  Combine the two, and what do we get? A five-pack of Coors Light Cold Hard Facts about Wi-Fi in the 6 GHz frequency band. Editor's note: This is a relatively long post, but 6 GHz Wi-Fi is an undoubtably robust topic. If you have questions after reading this blog, comment below or contact Ben via email or Twitter using the information below, and Sniff Wi-Fi will address those answers in a future post. We may be knee-deep in a global pandemic, but that doesn't mean your humble blogger can't brew up a post on the topic of 6 GHz Wi-Fi. Wi-Fi professionals will soon have unlicensed frequency available in the 6 GHz band. Here, then, are five facts to know about Wi-Fi in the soon-to-be-available 6 GHz frequency band. Fact #1: The 6 GHz band adds 1,200 MHz of spectrum for Wi-Fi The Federal Communications Commission (FCC) is the federal

Editor's note: In the original publication of this article, the relationship between Wi-Fi channel width and SNR was described imprecisely.  While the point of the article was correct -- that wider channel widths increase the likelihood of Wi-Fi frame failures for mobile client devices -- the mistakes have been corrected.  Thank you to Adrian Granados . Ahh, roaming. Few things capture the spirit of freedom like the ability to Roam wherever you want to go. Wi-Fi has its own brand of roaming, and there is one aspect of Wi-Fi roaming that often gets overlooked: 40 MHz and 80 MHz wide channels can make Wi-Fi users feel like they've been bounced from the Love Shack. Much has been written and spoken about the pros and cons of the three Wi-Fi channel widths: 20 MHz, 40 MHz, and 80 MHz. 20 MHz wide channels allow for the highest number of APs to be deployed -- nice for ultra high-density Wi-Fi -- because each AP takes up less of Wi-Fi's scarce frequency space.  In
