PHY metadata for 802.11n (HT) captures.

Member Data Documentation

◆ bandwidth

unsigned ieee_802_11n::bandwidth

Channel bandwidth in MHz (e.g. 20, 40).

◆ fec

unsigned ieee_802_11n::fec

Forward error correction type: 0 = BCC (Binary Convolutional Coding), 1 = LDPC.

◆ greenfield

unsigned ieee_802_11n::greenfield

True if the frame was transmitted in greenfield (HT-only) mode; false for mixed mode.

◆ has_bandwidth

unsigned ieee_802_11n::has_bandwidth

Non-zero if bandwidth contains a valid value.

◆ has_fec

unsigned ieee_802_11n::has_fec

Non-zero if fec contains a valid value.

◆ has_greenfield

unsigned ieee_802_11n::has_greenfield

Non-zero if greenfield contains a valid value.

◆ has_mcs_index

unsigned ieee_802_11n::has_mcs_index

Non-zero if mcs_index contains a valid value.

◆ has_ness

unsigned ieee_802_11n::has_ness

Non-zero if ness contains a valid value.

◆ has_short_gi

unsigned ieee_802_11n::has_short_gi

Non-zero if short_gi contains a valid value.

◆ has_stbc_streams

unsigned ieee_802_11n::has_stbc_streams

Non-zero if stbc_streams contains a valid value.

◆ mcs_index

uint16_t ieee_802_11n::mcs_index

Modulation and Coding Scheme (MCS) index specifying the 802.11n data rate.

◆ ness

unsigned ieee_802_11n::ness

Number of extension spatial streams (Ness) present in the HT PPDU.

◆ short_gi

unsigned ieee_802_11n::short_gi

True if a short guard interval (400 ns) was used; false for long guard interval (800 ns).

◆ stbc_streams

unsigned ieee_802_11n::stbc_streams

Number of Space-Time Block Coding (STBC) spatial streams used for this transmission.
