IEEE 802.11 is a set of standards for wireless LANs, and it defines various codes that can be used to identify network issues. These codes are typically found in debug logs or network analyzer reports. Understanding the Codes This Reason Code field explains why certain network management messages, like Disassociation, Deauthentication, DELTS, DELBA, DLS Teardown,Read more about IEEE 802.11 Reason codes to identify network issues[...]| WiFi
Introduction DFS is not a new topic and anyone who has a little bit of knowledge of RF or WiFi has some sort of understanding regarding DFS or DFS channels etc. There are a lot of blogs and posts on the topic. Whenever I read a blog or watch a video on DFS topic mostRead more about Dynamic Frequency Selection (DFS): Beyond Radar Detection[...] The post Dynamic Frequency Selection (DFS): Beyond Radar Detection appeared first on WiFi.| WiFi
MU-PPDU: We have explored the first part (MU-trigger frame) of MU-OFDMA transmission already in a different post. Once the following conditions are met: MU-RTS trigger frame sent by the AP CTS response from the devices or AP sends CTS Now AP can start sending the data. At this point, we should expect MU PPDU’s fromRead more about 802.11ax MU PPDU[...] The post 802.11ax MU PPDU appeared first on WiFi.| WiFi
My plan was to explain DL MU-OFDMA which includes trigger frames, CTS, MU-PPDU, and ACK in one post but that would become boring. so I have decided to split it into 2 posts. 1- MU-Trigger frame 2- MU-PPDU In this post, we will only look at MU-Trigger frame. Note: Let’s start: MU-OFDMA transmission can startRead more about 802.11ax MU-Trigger Frame (DL MU-OFDMA)[...] The post 802.11ax MU-Trigger Frame (DL MU-OFDMA) appeared first on WiFi.| WiFi
