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.

Python – Auto-Populate Tag Values in Ekahau Pro
Ekahau released a new version (v10.2) last month. The best feature out of this new version (for me at least) is the ability to create personalized tags for AP objects. Each tag can have a key and a value.

802.11ax Remote Packet Captures using the Jetson Nano
This solution will allow you to perform remote 802.11ax packet capture from your own laptop using the Jetson Nano. The benefit of using the Jetson Nano (and the Intel AX200 Wi-Fi card) to perform 802.11ax packet capture is that you get a lot more information in the RadioTap Header you get. The benefit of doing it remotely is that you never need to directly interact with the Jetson Nano OS (no need for keyboards, screens nor mouses)

WLAN Pi – Setup a Wi-Fi Hotspot
Thanks to Florent Lassia, we were able to configure the Wi-Fi NIC to bride to the Ethernet NIC. In the Hotspot mode, you can now have your Wi-Fi hotspot running, connect a client device to that Wi-Fi network and receive network connectivity to the LAN if your WLAN Pi is connected to the LAN via its Ethernet interface. We have detailed how to do it on this blog post: https://www.semfionetworks.com/blog/wlan-pi-bridge-wi-fi-hotspot-to-ethernet-interface
