This article contains information on how to calculate the operating margin of a wireless 802.11 network using a known distance between the two points. I wrote this quite a while ago and although the throughput of wireless links has dramatically increased the basic theory still applies. Of course we now have 5GHz available, which is very useful for this […]| MadPsy's Place
IEEE 802.11 is a set of standards for wireless LANs, and it defines various codes that can be used to identify network issues. These codes are typically found in debug logs or network analyzer reports. Understanding the Codes This Reason Code field explains why certain network management messages, like Disassociation, Deauthentication, DELTS, DELBA, DLS Teardown,Read more about IEEE 802.11 Reason codes to identify network issues[...]| WiFi
We've come to expect a standard degree of connectivity wherever we go, and regularly rely on WiFi to maintain our productivity, our organization, our health, and even our protection| Purple

In this brief WLPC Phoenix talk I presented some surprising real-world data gathered from 7SIGNAL Sapphire Eye and Mobile Eye on the major new features in Wi-Fi 6, 1024 QAM, OFDMA, and 6 GHz.| Frame by Frame
In this 7SIGNAL webinar I discussed the reality of OFDMA in Wi-Fi 6, dispelled some of the marketing myths, and shared some thoughts on how Wi-Fi can take better advantage of it in the future.| Frame by Frame
In this WLPC Phoenix talk I describe in detail how 802.11ax stations contend for channel access, using a combination of new and old features of 802.11. The idea was to show the full picture of what…| Frame by Frame
In this 7SIGNAL webinar I described how 802.11 contention is different when wide channel widths are in use, and how that has evolved with each new PHY up to 802.11ax.| Frame by Frame
