Purpose & Principle of Operation

MaîtreBadge serves as a wearable contactless smart ID card in a sealed, impact-resistant ABS housing for industrial safety, workforce management (WFM), and smart office systems. Four times per second (4 Hz), the badge transmits ultra-short UWB radio pulses, which are received by MaîtreAnchor TDoA or MaîtreAnchor AOA+TWR base stations to determine worker position with 10–30 cm accuracy, enforce hazardous-zone geofencing, detect falls/immobility (Man-Down), and trigger instant SOS emergency alerts.
