In 802.11ax communications, the trigger frame is used for multiple purposes. One of them is to allocate ressources for a specific multi-user OFDMA transmission. In this article, we are going to take a deeper look at some of the interesting fields we will find in this trigger frame. For more details, you can look at section [...]
As you know, all data rates are changing with 802.11ax, Hence, the new MCS table you can find here: https://www.semfionetworks.com/blog/mcs-table-updated-with-80211ax-data-rates In this article, we will see how we can figure out the data rate of a specific 802.11ax data frame. If you want to know how to capture 802.11ax data frames, refer to this article [...]
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 [...]
I recently purchased a Wi-Fi 6 device (Samsung Galaxy S10), and when I checked which date rate it was using over the Wi-Fi, this is what I got: I wanted to find out which MCS index and which modulation was used but after doing some research online, I couldn't find any easy resources that could [...]
I am really excited about 2019. The Wi-Fi technology is always evolving, bringing new challenges along the way. And this year is no exception. I am looking forward to the challenges that I will face this year and I am looking forward to the new learning experiences that 2019 will bring. In this article, I [...]
