Engineering basis
This model separates measured or published inputs from adjustable planning margins. Every proposal carries the assumptions forward.
The engine uses the 2025 ITU-R P.1238-13 site-general indoor model with environment-specific coefficients and full 3D transmitter-to-receiver distance. A design fade reserve is applied separately.
Each direct ray is intersected with the drawn walls. Loss is added only when the ray crosses the wall below its modeled height. Defaults are editable because thickness, moisture, reinforcement and incidence angle matter.
Human bodies are modeled as probabilistic line-of-sight blockers inside occupancy zones. ITU reports a 6–8 dB drop when one person enters a line-of-sight path at 1.7 GHz. The app uses 7 dB as a center value and limits stacking to reflect multipath.
Phones are treated separately. Receivers do not load an Auracast broadcast, but active Wi-Fi and Bluetooth devices share 2.4 GHz and can increase collision risk. The app converts ambient channel use and active-device duty into an explicit, capped interference reserve; commissioning still requires a spectrum and listening survey.
Measurement-based BLE interference studyThe Auri profile uses +20 dBm maximum output in North America. Its installation guidance recommends 1.8–3 m mounting height, facing the room, about 20% coverage overlap, and validation under normal full occupancy.
