Did I Mention That Location Services Is the End-game?
Ten years has validated my assertions (in 2008 and in 2009) that location services is the end game. Whether it’s used for asset tracking, people tracking, wayfinding, or even location-based
So-called ‘Ghost Frames’ Do Not Exist

802.11ax’s Achilles Heel
While there are some technical reasons to be excited about the soon forthcoming 802.11ax (hereafter, just 11ax) technology, it has one big Achilles Heel that must be considered by any
Wi-Fi Throughput
There must be 10Gbps of Wi-Fi throughput hype out there, and I want to explain expected throughput for 11ac and 11ax WLANs in a way that is clear to everyone.
Aerohive Innovation
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
802.11ax Is Not
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
It’s All About The People
My friend Keith Parsons and I are fond of saying, “It’s All About The People.” Because it is. People and relationships are what’s really important in life, but everyone (including
WiFi Design and Deployment Methodology
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
AirCheck G2: Devin’s Seven
Simply because it’s awesome, I thought I would write a blog about the AirCheck G2. It’s my favorite WiFi diagnostics tool, hands-down. It does so many things in such a
Dual-5GHz Radio APs
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
Primary and Secondary Coverage
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
Why You Should Disable Lower Legacy Data Rates
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
Ruckus is Officially ‘Off the Leash’
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
Technical Analysis: Blackbox HD3 Wi-Fi Solution
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.
Moo-MIMO
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
Hedge Fund Targets Aerohive
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
A New Generation of Wi-Fi Design
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.”
The Need For Continual Monitoring
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
Measuring and Annotating Wall Attenuation for Predictive RF Site Surveys
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
Top Ten Tune-up Tips
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
Buying Value: 2×2:2 vs. 3×3:3
Within most enterprise manufacturers who sell both 2×2:2 and 3×3:3 platforms, the ratio of overall sales is 80-85% 2×2:2 and 15-20% 3×3:3. Given those numbers, someone might ask why do
Spectrum-only Surveying
Most any technical professional within the Wi-Fi market can tell you what an RF Site Survey is. Far fewer, but still a reasonable number of professionals, can perform an RF
Wi-Fi Migration to Pure 5GHz
Now that the 2.4GHz is Dead gauntlet has been thrown down, I thought it prudent to help those who are trying to move to a Pure-5GHz Wi-Fi infrastructure. While there
IoT Fly By
Just as we thought everything was stabilizing after the big BYOD rush…here comes its big brother…IoT. As soon as you dig into the nuts and bolts of IoT, you realize
Validated WIPS
When the FCC recently ordered Marriott International and Marriott Hotel Services to pay a $600,000 fine for “jamming mobile hotspots” within their own facilities, the Wi-Fi world suddenly changed. There
My Top Six Lessons From My First Six Months
As many of you know, I kicked off Divergent Dynamics, Inc. in April 2014. I started with no money in the bank, no insurance, bills pouring into my mailbox like

For Whom The IoT Bell Tolls
Do not ask for whom the IoT bell tolls. It tolls for thee. That means you…as in, “ready or not, here I come.” The Internet of Things (IoT) phenomenon (or
Wi-Family
When our brother Keith Parsons took that historic swing on that faithful day in February 2014, he knocked the ball over the cheap seats, out of the stadium, and into
Sentis: How The Brain Works
I found an entire animated series on the brain, and it’s extraordinarily informative. It talks about the emotions, subconscious and conscious, limitations, social behavior, and more. Well worth your time.
Devinator’s TriType: The Truth Teller
The Devinator (me) is a Social 8W7, 8-6-4 Tritype. Thanks to David Fauvre for posting this video on YouTube! He and I share this Tritype (he’s a 4-6-8), and I’m
