Technology Updates

Back-to-back innovative product releases from Aerohive…hmmm.  Who would’ve thought that they would re-enter the innovation game after a 5-year hiatus. Not me, but I must say that I’m very pleasantly surprised. I had almost written them off, but it looks like someone or something breathed new life into the company, and I’m glad to see […]

So much has been and will be said about the upcoming 802.11 PHY amendment called 802.11ax (hereafter just “11ax”) that I felt I needed to chime in to counteract some of the expected poor marketing. This blog is not about what 802.11ax is, but rather is about what 802.11ax is not. If you read the

In each of my weekly classes, I do a full walk-through of the “Define, Design, Deploy, Diagnose (Validate/Optimize)” process. It’s never a surprise when most of the students are excited to see a documented, vendor-neutral walk-through of the process.  I’m always asked for a copy of the flow chart (shown below) document so that the

With client density continually on the rise, and more high-density use cases popping up all the time, it only makes sense to replace unused 2.4GHz radios with 5GHz radios in many deployment scenarios. As the 2.4GHz band becomes more crowded with WiFi and non-WiFi devices, the pressure relief valve (so to speak) will be adding

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

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

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
