4383 * The comment in the radiotap.org page about the suggested
4384 * xchannel field says:
4385 *
4386 * As used, this field conflates channel properties (which
4387 * need not be stored per packet but are more or less fixed)
4388 * with packet properties (like the modulation).
4389 *
4390 * The channel field, in practice, seems to be used, in some
4391 * cases, to indicate channel properties (from which the packet
4392 * modulation cannot be inferred) and, in other cases, to
4393 * indicate the packet's modulation.
4394 *
4395 * There is even a capture in which the channel field indicates
4396 * that the channel is an OFDM channel with a center frequency
4397 * of 2452 MHz, and the data rate field indicates a 1 Mb/s rate,
4398 * which means you can't rely on the CCK/OFDM/dynamic CCK/OFDM
4399 * bits in the channel field to indicate anything. (There are
4400 * also captures in which a 1 Mb/s packet has the CCK flag set,
4401 * so it clearly doesn't indicate how the packet was transmitted.)
4402 *
4403 * That makes the channel field unusable either for determining
4404 * the channel type or for determining the packet modulation,
4405 * as it cannot be determined how it's being used. The xchannel
4406 * field might well be used inconsistently as well.
4407 *
4408 * Fortunately, there are other ways to determine the packet
4409 * modulation:
4410 *
4411 * if there's an FHSS flag, the packet was transmitted
4412 * using the 802.11 legacy FHSS modulation;
4413 *
4414 * otherwise:
4415 *
4416 * if there's an HE field, the packet was transmitted
4417 * using one of the 11ax HE PHY's specified modulations;
4418 *
4419 * otherwise, if there's a VHT field, the packet was
4420 * transmitted using one of the 11ac VHT PHY's specified
4421 * modulations;
4422 *
4423 * otherwise, if there's an MCS field, the packet was
4424 * transmitted using one of the 11n HT PHY's specified
4425 * modulations;
4426 *
4427 * otherwise:
4428 *
4429 * if the data rate is 1 Mb/s or 2 Mb/s, the packet was
4430 * transmitted using the 802.11 legacy DSSS modulation
4431 * (we ignore the IR PHY - was it ever implemented?);
4432 *
4433 * if the data rate is 5 Mb/s or 11 Mb/s, the packet
4434 * was transmitted using the 802.11b DSSS/CCK modulation
4435 * (or the now-obsolete DSSS/PBCC modulation; *if* we can
4436 * rely on the channel/xchannel field's "CCK channel" and
4437 * "Dynamic CCK-OFDM channel" flags, the absence of either
4438 * flag would presumably indicate DSSS/PBCC);
4439 *
4440 * if the data rate is 22 Mb/s or 33 Mb/s, the packet was
4441 * transmitted using the 802.11b DSSS/PBCC modulation (as
4442 * those speeds aren't supported by DSSS/CCK);
4443 *
4444 * if the data rate is one of the OFDM rates for the 11a
4445 * OFDM PHY and the OFDM part of the 11g ERP PHY, the
4446 * packet was transmitted with the 11g/11a OFDM modulation.
4447 *
4448 * We've already handled the HE, VHT, and MCS fields, and may
4449 * have attempted to use the channel and xchannel fields to
4450 * guess the modulation. That guess might get the wrong answer
4451 * for 11g "Dynamic CCK-OFDM" channels.
4452 *
4453 * If we have the data rate, we use it to:
4454 *
4455 * fix up the 11g channels;
4456 *
4457 * determine the modulation if we haven't been able to
