One Answer:
The radiotap header is not part of the 802.11 frame structure. It is a container for frame metadata which has been developed, like other pseudo-headers, in the absence of any dedicated container for metadata in the pcap file format. The newer pcapng format has introduced the idea of providing space for metadata clearly separated from the actual frame bytes, yet there is no proposed standard for any pcapng container replacing the radiotap header. More details about the radiotap header can be found at its home page. There are also competing solutions to the same issue, like e.g. the TZSP. answered 01 Oct '16, 00:40  sindy |
