Hi folks;

I bought the AirPcap device and am sniffing away. I am curious about some of the fields in the Radiotap header. Can someone explain the SSI Signal/Noise values in the packet capture. Are those fields/values inserted by AirPcap when upon packet capture ?? or are they already in the received packet ??

I have found surprising little online documentation providing an explanation of the fields.

thanks, walter

To find the online documentation, you need to look at, for example, the defined-fields page at the Radiotap Website.

Those fields are not in the received packets; they are inserted by the hardware and/or driver, as per the "Background" section of the Radiotap home page.
