updation needed for IEEE 802.11n packet capturing #411

Closed Bala26TN closed 2 months ago

Bala26TN commented 2 months ago

Greatings, this project has helped me a lot, i would like to know how can this be updated for capturing all modes of WIFI that include IEEE 802.11(n/ac/ax) also, can u help me with the updated and extra blockes to be added for doing the same. thanks in advance.

Very happy that the project helped you. Extending it for other standards would be a major effort, as they differ in bandwidth, preamble, codes (e.g., LDPC vs convolutional codes), MIMO, etc. etc. Also doing >=80MHz and higher MIMO orders on the CPU, might be hard. If you want to give it a try, I'd generate a reference frame (for example with the MATLAB WiFi Toolbox) and use the standard to come up with code to decode the reference frame.

thank you for the response where can i get the code where u have generated the reference frame and decoded it. basically i have to capture all WIFI packets that are present in the surrounding. but i am missing those devices having WIFI IEEE802.11n that why i have posted the query.

I didn't use a reference frame, but I should have. You can just look for example for the MATLAB toolbox. https://de.mathworks.com/products/wlan.html But, again, this will be a major effort. I'd assume 6 to 12 months.
