The radio supervisor picks the lowest-power layer that meets QoS, and stitches multiple layers for resilience — from 30m BLE to global LEO satellite fallback.
BLE / UWB · 0–30 m
Personal, ultra-low power.
Wi-Fi Direct / 6E · 30–250 m
Urban density, high bandwidth.
LoRa / Sub-GHz · 1–15 km
Rural & long-range telemetry.
Drone / Vehicle Relays · 5–50 km
Mobile gap bridging.
LEO Satellite Fallback · Global
Last-resort uplink.
