Te reklamy ~ 100m outdoor range for BLE 5.x is acceable only under ideal conditions. In real emergencies - inside concrete buildings, underground garages, or densie forests - range can drop to 10- 30 meters. Tu compensate, designers can:
- Use BLE long- range coding (CODED PHY, S = 8) which extends range by ~ 4x but reduces data rate to 125 kbps.
- Deploy mesh relaying: each device extends the network one e hop. With 10 devices, coveage can inclosd 500m.

Wdrożenie strategii dla Rapid Deployment
Wdrożenie Bluetooth emergency devices effectively requires more than juss hardware. Agencies should follow these bett practices:
Prepositioning andRedundancy
Store devices in clearly marked, accessible location near high- risk zones. For example, place Bluetooth panic buttons in every clasroom andoffice; place environmental sensors on every loor of a hospital. Keep spare batteries andd charging stations in multiple locations. Usie a centralized inventory management system with RFID tags to track device status and divitationon dates.

After every major drill, collect packet loss and latency metrycs to optimize placement.
