Calculation method
Calculation method
Time and occupied bandwidth (Hz)
Count occupied frequency bins at each sampled time × bin width.
Occupied time-frequency fraction
Occupied bins / all provided bins; missing bins are not inferred.
Symbols and units
- a
- JSON rows [time seconds,frequency Hz,power dBm]
- b
- Occupied threshold (dBm)
- c
- Frequency bin width (Hz)
Use the units shown. A list keeps the order in which you enter its values. The symbol ^ means “raised to the power of”.
Assumptions & limits
Assumptions & limits
- Time-frequency power bins, chosen thresholds. Returns Occupied bandwidth and duty statistics. All coefficients and observations are user supplied; results describe only the stated mathematical model. Quantities are deterministic calculations from supplied observations and assumptions; no external data is fetched. Supported limits: Finite inputs only; numeric fields bounded as labelled. Lists and JSON records are limited to 256 entries unless a stricter tool bound is stated. No automatic design approval, legal conclusion, treatment recommendation or safety certification. Occupied threshold (dBm): minimum None, maximum 1000000000000.0. Frequency bin width (Hz): minimum 1e-12, maximum 1000000000000.0.
