Sniff Wi-Fi

Qualcomm, owners of the Atheros line of Wi-Fi radios, recently announced the availability of Wi-Fi 6E chips. Game onnnnnnn! 6 GHz Wi-Fi is here. Sort of... Qualcomm is selling Wi-Fi 6E (802.11ax w/ 6 GHz support) chips, but we don't yet know when enterprise-grade APs and mobile devices will begin supporting 6 GHz Wi-Fi. Chip-to-product timelines can vary. Wi-Fi 5 (802.11ac) saw enterprise WLAN vendors sell products only a few months after chip announcements. Wi-Fi 6 (802.11ax) saw the big vendors wait a year or more before introducing new AP models. A ton of concerns factor into a vendor's decision on when to develop, manufacture and market new AP technology. Vendors with small market share may be extra eager. Aerohive tried to boost their enterprise Wi-Fi profile by being a leader in Wi-Fi 6. On the other hand, some vendors' enthusiasm for new Wi-Fi hardware may be dulled by competing organizational initiatives. Aruba/HPE, for example, was veering f...

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...
