Reference range
MedlinePlus lists average healthy adult resting breathing at 12 to 18 breaths per minute.
What studies show
VitalCSI reported respiratory-rate estimation using consumer Wi-Fi hardware with airflow-sensor comparison. BreatheSmart reported high classification accuracy in controlled RF experiments.
What SteadyHome can claim
This supports prototype wellness sensing and calibration work. It does not justify claiming clinical-grade breathing monitoring without product-specific validation.
Signal method
Research often uses CSI amplitude, phase, spectral features, and filtering.
Product boundary
SteadyHome should say respiration-oriented wellness signal, not diagnosis.
Research belongs in the product, but so does restraint.
The safest SEO position is to explain the technology honestly and show the compliance boundary.
