The blog post makes no mention of the cellular network congestion/dropped packets that affected people during the power outage. I had bars but was unable to load websites for most of the day. Were Waymos unaffected by the network problems, or were request timeouts encompassed in the word “backlog” used by the blog post?
- AlotOfReading 9mo agoThe networking on AVs is usually redundant across multiple cellular networks to deal with coverage and outage issues. They also use business sims, which usually have a slightly higher network priority than consumers. If waymo's also negotiated to use one of the infrastructure QCIs instead, it would take some seriously disastrous network conditions for them to experience meaningful congestion.
- fowl2 9mo agoI wonder if the cars also have some sort of mesh (LoRaWAN?) network to help each other out in temporary dead zones, emergencies, etc.
- AlotOfReading 9mo agoBandwidth is problematic for mesh. A remote assistance situation would involve at least 4 high definition camera streams, and ideally with minimal latency. It's challenging to put that much data onto public spectrum even if you wanted to make a custom radio.
- fowl2 9mo agoI was thinking more for communicating the “mass disruption in progress” message - or even just distributing the manually verified “traffic lights down” data between vehicles.
