802.11n Flags and description

Postby zero_one_zero » Mon Jun 10, 2013 2:00 pm

Hi,

I am using the latest version of Omnipeek with OmniWifi Dongle and I see a bunch of 802.11n Flags like STBC, Short Guard, etc, Where do I find the description/explanation for these flags in Omnipeek ? I couldn't find it in the help.

For Example:
802.11n flag for STBC is set to 1. Does this mean the frame was captured as STBC frame or it was captured with Rx STBC of 1?

Here is a link to the 802.11n draft by the WiFi Alliance which will contain explanations of all the 802.11n flags:

If the STBC bit is set in a beacon, it just means the AP is capable of using that feature.

Hi DJWP,

Thanks for the reply and the link. However, my question is related to Omnipeek's 802.11n Flags field.

I would like to know what the bit fields represent in 802.11n Flags in Omnipeek. It is a 32 bit field and the LSB bit0 when set indicates 20MHz Lower and bit 5 is set when Long GI (Guard Interval) is set.

Where are the descriptions for other bit field values ?
