}

Normalised receive metadata: the fields every source can state in the same units.

A field is an Option when some source cannot state it. The Espressif 802.11ax-generation MAC (C5/C6), for instance, reports no MCS, STBC, guard-interval or antenna bit, and an absent value is None rather than a guess.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

timestamp_us: u64

Receive time on the node’s clock, microseconds. 64-bit: it does not wrap within a session.

rssi: i8

Received signal strength, dBm.

noise_floor: i8

Noise floor, dBm.

channel: u8

Primary channel number.

secondary: Secondary

Position of the secondary channel, for a 40 MHz-capable channel.

bandwidth: Option<Bandwidth>

Bandwidth of the measured PPDU, when the source reports or implies it.

ppdu: PpduFormat

Format of the measured PPDU.

mcs: Option<u8>

MCS index, for HT/VHT/HE PPDUs where the source reports it.

stbc: Option<bool>

Whether the PPDU used space-time block coding.

sgi: Option<bool>

Whether the PPDU used a short guard interval.

n_rx: u8

Receive chains the measurement covers.

n_ss: Option<u8>

Spatial streams in the measured PPDU, when known.

antenna: Option<u8>

Index of the antenna the PPDU was received on, when reported.

sig_len: u16

Length of the received PPDU including its FCS, bytes.

rx_state: u8

Receive state: 0 = no error, others are source-specific error codes.

not_sounding: Option<bool>

Whether the PPDU was not a sounding PPDU (Some(false) = sounding, i.e. an NDP), when the source distinguishes them.

aggregation: Option<bool>

Whether the MPDU arrived inside an A-MPDU, when reported.

frame_seq: Option<u16>

The 12-bit 802.11 sequence number of the measured MPDU, when the source reports it. Assigned by the transmitter, per TID, and repeated on retries, so it measures loss on the air per transmitter. Use Envelope::stream_seq to count loss between node and host.

vendor: VendorRx

Fields specific to the source’s chip family.
