Learning Wi-Fi the Right Way — My First Certifications

After those first few surveys, I knew I needed more. “Green is good, grey is bad” wasn’t going to cut it forever.

So I did what I always do when curiosity outpaces knowledge: I opened a browser and started searching. Wi-Fi training courses. Two names kept coming up, no matter where I looked: Ekahau and CWNP. One leaned more theoretical, the other more hands-on. I went with hands-on. And so I booked my very first Wi-Fi specific training:

The Ekahau ECSE Design course.

Four Days That Changed Everything

That week laid the foundation for everything that came after. Wi-Fi standards, frequency bands, what actually matters when designing a wireless network — and a whole new vocabulary I didn’t know existed. LCMI, CCI, airtime utilization, green diamond, client offsets… terms that had been flying over my head on job sites suddenly started making sense.
Our instructor was Ferney Munoz — CWNE #187 — and he walked us through everything from inside, and yes, outside his legendary man-cave. By the end of day four, I wasn’t just interested in Wi-Fi anymore. I was hooked

Meeting the Sidekick

Fresh off the course, I was ready to put it all into practice. And I had a new tool to do it with: the Ekahau Sidekick 1.
Coming from a laptop with a Wi-Fi dongle taped to the back, this felt like a serious upgrade. And it was. But being equipped with better tools doesn’t automatically make you better at using them.

I still made my share of rookie mistakes.
Forgetting to freeze the AP during a survey. Leaving the iPad on a table while still tethered to the Sidekick — and only remembering when it clattered to the floor. Not scaling the floor plans before starting a walk. The classics. I think of them now as the mandatory initiation rites of anyone who’s serious about this craft.

Slowly, though, the confidence started building. And with every project I finished, the questions kept stacking up. Which, by now, I’d learned to take as a good sign.

Round Two: Troubleshooting

The next step was the ECSE Troubleshooting course — another four-day deep dive, but this time focused entirely on tracking down and fixing Wi-Fi problems rather than designing networks from scratch.
Scott McDormet – CWNE #299 – was our instructor. Brilliant teacher. Also responsible for the fact that I now have opinions about alpacas. Somehow that felt completely normal by day two.

The Final Piece: ECSE Advanced

With two certifications down, there was only one left to go. The ECSE Advanced course completed the trilogy — four days that added a whole new layer to everything I’d built so far. Floor plan manipulation, wall calibration, more client offsets, and a stack of techniques I’d find myself using on real projects almost immediately.

 

But the thing that surprised me most had nothing to do with RF. Our instructor François Vergès is, in the truest sense of the word, a custom reporting wizard.

It doesn’t sound glamorous. It’s not. But when you’re handing over a completed design or survey to a client, being able to deliver a clean, professional, branded report makes a real difference.

Three certifications down. The tools were familiar, the surveys were getting easier, and the confidence was real. But confidence has a way of reminding you how much you still don’t know. I wanted to go deeper — past the surveys and the software, all the way down to how Wi-Fi actually works.
That curiosity only pointed in one direction.

 

The CWNE journey had begun.
