Industrial-grade BLE protocol for asset tracking, personnel safety, and environmental monitoring
AltessaBeacon is a BLE 5.0 advertising protocol designed for enterprise IoT applications in challenging industrial environments. Unlike consumer beacon protocols, AltessaBeacon prioritizes:
- Worker Safety — Sub-second emergency response with 23-packet delivery over 60 seconds
- Operational Reliability — Graceful degradation under low battery conditions
- Enterprise Security — AES-128-CCM encryption with anti-replay protection
| Feature | Description |
|---|---|
| Extended Emergency Transmission (EET) | 23 packets over 60 seconds ensure emergency signals reach safety systems |
| Battery-Aware Interval Scaling (BAIS) | 5-state power management extends battery life while preserving emergency functions |
| Fall Detection | 4-phase algorithm with automatic EET triggering |
| LE Coded PHY (S=8) | +6-12 dB link budget for extended range in emergencies |
| TLV Frame Structure | Modular, extensible packet format |
| Three-Level Identification | Major/Minor/ShortDeviceID for hierarchical organization |
