Assumptions & limits
Assumptions & limits
- Received-power estimate, receiver threshold. Returns Nominal link margin. 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. Received signal (dBm): minimum None, maximum 1000000000000.0. Receiver threshold (dBm): minimum None, maximum 1000000000000.0.
