Devices / channels
1 / 120 sessions

Hours sum session durations across devices; simultaneous captures add together. Days use session start dates in Europe/Bratislava. Decoded means every segment has frame rows; it does not certify usable CSI or current reductions. 1 sessions have unknown duration.

Timeline data by device and start day
The interactive timeline uses these same daily totals. Hours sum session durations; they do not imply continuous coverage.

Snapshot, definitions & data access

This page covers sessions listed in the lake snapshot, 407205 (2026-10-26T22:19+00:00). It cannot show captures absent from that snapshot. Channel and band are session metadata, not a per-channel dwell-time measurement. Missing durations appear as a dash; known durations still contribute to the totals.

Archive inventory: 7483 sessions, 614 quarantined and 2371 infrastructure. A claim is a card that names the session id, or whose declared capture profiles and window reach it, read from the vault when the snapshot was built. Sessions the lake already attributes carry that as a third source. Infrastructure profiles (console, smoke, benches, anything under two minutes) can never be claimed and are counted apart, never as unclaimed.

Quote useful_yield: (records − empty records) ÷ frames the radio saw. capture_yield counts an all-zero record as delivered. A low capture_yield on 2.4 GHz is DSSS/CCK traffic that yields no channel estimate, not a quiet channel. Both are derived ratios from two independent counters and exceed 1.0 on some sessions; the counts are exact, the ratios are not.
