Always clear
The safety channel is reserved by regulation. Nothing else is allowed on it. It cannot get crowded.
Safety and autonomy
Safety gets its own channel.
Machine-to-machine safety signals run on a dedicated, protected frequency. No matter how busy the site network gets, stop signals and proximity alerts get through in milliseconds. Every time.
Machine to machine
Equipment talks directly to equipment. Even if the base station goes down, the safety mesh keeps working.
Everything on record
Every connection and every safety event is logged automatically. When you need proof, it is one search away.
What runs on it.
The safety tier is a mesh between machines, with no base station in the loop. It rejoins the site network and the record when connectivity returns.
- Work-zone deconfliction between crews and equipment.
- Haul-road intersection negotiation, machine to machine.
- Proximity interlocks between machines, and between machines and people.
- Stop-class signals propagated on a 1 ms slot structure.
Why it shares no fate with site data.
Two properties make the safety tier independent of everything else happening on the network.
Reserved spectrum
Nothing else is allowed there
The 1.9 GHz band used for the safety tier is allocated to this technology exclusively. Site data, Wi-Fi, and consumer gear cannot enter it, by rule and not by configuration.
Frequency gap
Far from the busy bands
The safety tier sits well away from the congested access bands in both directions. Saturating Wi-Fi or the site cell leaves fleet coordination untouched.
The result is meant to be citable directly in an autonomy safety case: fleet coordination does not depend on the health of the data network.
The record writes itself.
Every authorization and every attachment goes into a tamper-evident ledger as it happens, so proof is a search and not a reconstruction.
- Every transmission authorization: which device, where, on what band, at what power, and when.
- Every attachment, including phones carried over the site network on their own carrier.
- Every safety event on the deterministic tier.
- Queryable by the site operator, and by insurers or regulators when the operator allows it.
