Mist AP SSID on/off with MicroController
The idea behind this device is to provide a portable tool that allows you to stop the radios of a Mist Access Point.To make it more relatable, let's consider a scenario: Imagine a school with Wi-Fi access for students. However, teachers are unhappy to see students scrolling through their phones during class time. It's time to take action. With this designed box, you can easily disable the access point with a single push of a button (instead of unplugging it or accessing the Mist portal).

What is Wi-Fi DevOps?
DevOps is a pretty popular word in the networking industry right now. More and more tools allow for network automation and programmability. Slowly but surely, we are seeing these tools becoming available in the Wi-Fi space. In the past couple of months, at SemFio, we have been involved in a few Wi-Fi automation projects. I wanted to use this blog article to explain what Wi-Fi DevOps is, from our point of view.

Python – Auto Rename Cable Notes in Ekahau
Naming cable notes in Ekahau is quite a manual process. You have to enter your note description at the end of drawing the cable note on the map.What I like to do on my projects is rename the cable notes in the following way: "IDF-1 to AP01". We then re-use this description in our report to provide the information to both the customer and the installers.
