(There are * also captures in which a 1 Mb/s packet has the CCK flag set, * so it clearly doesn't indicate how the packet was transmitted.) * * That makes the channel field unusable either for determining * the channel type or for determining the packet modulation, * as it cannot be determined how it's being used. The xchannel * field might well be used inconsistently as well. * * Fortunately, there are other ways to determine the packet * modulation: * * if there's an FHSS flag, the packet was transmitted * using the 802.11 legacy FHSS modulation; * * otherwise: * * if there's an HE field, the packet was transmitted * using one of the 11ax HE PHY's specified modulations; * * otherwise, if there's a VHT field, the packet was * transmitted using one of the 11ac VHT PHY's specified * modulations; * * otherwise, if there's an MCS field, the packet was * transmitted using one of the 11n HT PHY's specified * modulations; * * otherwise: * * if the data rate is 1 Mb/s or 2 Mb/s, the packet was * transmitted using the 802.11 legacy DSSS modulation * (we ignore the IR PHY - was it ever implemented?); * * if the data rate is 5 Mb/s or 11 Mb/s, the packet * was transmitted using the 802.11b DSSS/CCK modulation * (or the now-obsolete DSSS/PBCC modulation; *if* we can * rely on the channel/xchannel field's "CCK channel" and * "Dynamic CCK-OFDM channel" flags, the absence of either * flag would presumably indicate DSSS/PBCC); * * if the data rate is 22 Mb/s or 33 Mb/s, the packet was * transmitted using the 802.11b DSSS/PBCC modulation (as * those speeds aren't supported by DSSS/CCK); * * if the data rate is one of the OFDM rates for the 11a * OFDM PHY and the OFDM part of the 11g ERP PHY, the * packet was transmitted with the 11g/11a OFDM modulation. * * We've already handled the HE, VHT, and MCS fields, and may * have attempted to use the channel and xchannel fields to * guess the modulation.
