For those of you who have attended an Ekahau ECSE course or my CWNA course, you will remember the discussions of “Primary” and “Secondary” RF coverage when using predictive modeling software to design your Wi-Fi infrastructure. The goal of this blog is to quickly and visually explain the difference between the two. “Secondary” coverage is […]

There are arguments for and against disabling low data rates, and it’s my hope, that after reading this blog, you will understand why disabling lower legacy data rates may help your WLAN perform better. My only basic (mandatory) rate is typically 12M. All rates below 12M are disabled. All rates above 12M are enabled/optional. MCS

It looks like Ruckus took stock in the immortal words of Harvey Penick when he said, “Take Dead Aim.” No longer leashed to a controller, Ruckus’s new Unleashed controller-less Wi-Fi solution aims squarely at the SMB. Full Disclosure: I’m not being paid by Ruckus (or anyone else) to write this blog. After playing with the

If you’ve never heard of Black Box’s “InnerWirelessHD3” solution, this blog is dedicated to a technical analysis of it. I will abbreviate the name to just “HD3” in this blog. I will start by saying that I find no additional benefits beyond what a standard deployment provides, and that HD3 is grossly mis-marketed by Black

I readily admit that I could be all wet on this blog, so I have posed the title as a request rather than an assertion. I am going to state my current opinions on various aspects of 802.11ac Wave-2 technology, as it relates to enterprise customers, in the hopes that if I’m off-base, someone smarter
Aerohive has been doing quite well since their IPO. There are always areas for improvement, but all-in-all, I’m happy with the company’s numbers to date. Which brings me right to my point. There’s been something fishy going on with Aerohive’s stock prices. Early on, I was suspicious that it was being artificially held down, but

I have recently overheard the following in regard to “selling more APs.” “Let’s recommend two APs per classroom for more capacity.” “Just go with one AP per classroom. It’s easier.” “We recommend an 8-radio array per classroom for future proofing.” I’m in no way poking at any vendor here. If anything, I’m poking at those

2.4GHz interference advances with the determination of General George S. Patton, perhaps with General “Chesty” Puller as a teammate. BYOD, IoT, and STUFF fuels the onslaught. Because of so many devices (Wi-Fi, other types of communication devices, and unintentional interference sources) being haphazardly thrown into the 2.4GHz band both now and in the immediate future,

Like all other “survey” related tasks, measuring and annotating wall attenuation starts with marking up a floor plan. While the tiny print makes Figure-2 a little difficult to read, hopefully an explanation of what you’re viewing will help you understand the tasks that were performed. Most experienced Wi-Fi engineers will tell you that there’s no

Much of the work I do on customer networks these days is repetitive. That’s not to say that it’s always simple work, but I do see the same things over and over again. This blog does not take into consideration minor/unique system configuration tweaks. It does, however, take into consideration that some features should be
