SETU
Survivor Emergency Transmission Unit
“A bridge that doesn't need a network.”
When a disaster takes cell towers down, the people who most need to be found are the ones who can't send anything. SETU turns the phones around them into the network.
How it works
Speak
A trapped person records a short spoken report. No signal or internet is needed.
Triage on the phone
On-device AI transcribes the report, gives it a START triage tag, and packs it into a tiny payload signed with Ed25519.
Hop
Nearby phones running SETU pass the payload along over Bluetooth, one hop at a time. Because it's signed, any change a relay makes is detected.
Map and dispatch
At the command center, the dashboard verifies each report, clusters related ones, maps them, and helps responders decide who to send where.
Design choices
- Ed25519-signed payloads
- Relays carry reports but can't tamper with them.
- START triage tags
- Every report arrives already sorted by urgency, using the standard mass-casualty triage scheme.
- Automatic clustering
- Reports about the same incident are grouped, so responders see incidents rather than a flood of messages.
- Offline multilingual translation
- A survivor and a responder don't need to share a language, or an internet connection.
- Zero-backhaul command center
- The responder dashboard runs without any link to the outside internet.
