Detailed Description

TLV payload carrying wireless signal and channel quality metrics for a captured packet.

quality takes observed values of 15, 20–27, 50–54, 208, and 213. conditions takes observed values of 0x00, 0x02, and 0x90. reserved takes observed values of 0x00 or 0x80; the 0x80 value co-occurs with conditions = 0x90.

Member Data Documentation

conditions

uint8_t tlv_wireless_info::conditions

Bitmask of wireless conditions flags (e.g. WIRELESS_WEP_SUCCESS).

frequency

uint8_t tlv_wireless_info::frequency

RF channel frequency on which this packet was captured.

quality

uint8_t tlv_wireless_info::quality

Wireless signal quality indicator; interpretation is vendor-specific.

qualityPercent

uint8_t tlv_wireless_info::qualityPercent

Wireless signal quality expressed as a percentage (0–100).

rate

uint8_t tlv_wireless_info::rate

Wireless data rate at which this packet was received.

reserved

uint8_t tlv_wireless_info::reserved

Reserved; observed as 0x80 when conditions is 0x90, otherwise 0x00.

signalStrength

uint8_t tlv_wireless_info::signalStrength

Raw received signal strength value reported by the wireless hardware.

strengthPercent

uint8_t tlv_wireless_info::strengthPercent

Received signal strength expressed as a percentage (0–100).
