OK, so:

        1) Would the link-layer header include any radio metadata?  For 802.11, there are various forms of radio 
metadata headers, such as the radiotap header:

                http://www.radiotap.org

           If so, what would the format of the radio metadata be?

        2) The 2.2.2 "Implementation by Sigfox" section of the spec shows, on page 14, a frame structure.

           In the captures, is the first byte of frame data (following the radio metadata, if there is radio metadata, 
or at the beginning of the packet, if there is no radio metadata), the first byte of the Preamble/Type?

        3) Is the CRC-16 included with the frames?
