Sniff Wi-Fi

In a recent Sniff Wi-Fi post, your humble blogger argued that upgrading to Wi-Fi 6 is a fool's errand.  A number of respected WLAN professionals disagree with my argument. They believe that many organizations would be well-served to upgrade to Wi-Fi 6, rather than waiting for Wi-Fi 6E.  Why upgrade to a non-6 GHz standard, when 6 GHz Wi-Fi has now been approved? There are reasons... Making one's own counter argument is a tricky endeavor. The temptation to construct and incinerate straw men is powerful. There is a reason that the right to cross-examine is ingrained in the constitution of the United States of America, as part of the 6th Amendment: "...The accused shall enjoy the right... to be confronted with the witnesses against him; to have compulsory process for obtaining witnesses in his favor..." In layman's terms (and this has to be the first literal usage of the phrase "layman's terms" in the history of Sniff Wi-Fi), the above is refer...

With 6 GHz Wi-Fi around the corner in the form of Wi-Fi 6E, upgrading to Wi-Fi 6 becomes a risky proposition. It was just over a year ago that your humble blogger heard the "news" about Wi-Fi 6 (802.11ax). The Samsung Galaxy 10 was on the market. It supports Wi-Fi 6. Our sales engineers were happy to inform us of the upgrade possibilities. Today's news is about a new technology, Wi-Fi 6E. It offers access to the 6 GHz frequency band, which is great. It is not available as a software upgrade from Wi-Fi 6 (as your humble blogger discovered recently ), which is not so great. "Future proofing" has always been elusive. As we are all experiencing right now, nothing can protect an organization from the whims of nature (human or otherwise). I wasn't saying "wait for 802.11n" in 2005 or "wait for 802.11ac" in 2011. If budget, manpower and leadership align, go for it. The reason your humble blogger says "wait for Wi-Fi 6E" today...

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 ...

The new Wi-Fi 6 (802.11ax) standard offers several new technologies, but only one that really matters (for most enterprises): OFDMA. Have you heard about Wi-Fi 6?  (Or, at least, 802.11ax?)  If you work in or around networking or Wi-Fi, you probably have.  Your humble author has read about it in blogs, tweeted about it, streamed about it on Twitch and watched commercials about it on college football telecasts. It was the last thing -- the TV commercials -- that gave yours truly a double-take.  "Is Wi-Fi 6 that big?", I murmured to myself while taking in CDW's commercial for Cisco's Wi-Fi 6 gear.  Commercials on national sports broadcasts aren't cheap, so someone must be asking about it.  (Or at least think there's money in it.) The standard (technically an "amendment", not a full-blown IEEE standard) Wi-Fi 6 is based upon is 802.11ax, and according to the latest 802.11 Working Group timeline , 802.11ax won't be finished for several month...
