It's terrifying to hear him mention self-driving cars as a use case for super low latencies. If a few milliseconds of network latency compromises some safety system in a car, that's bad. I'd be engineering a car for worst case scenarios, not for reliance on a fast network.
It makes me think of this. https://en.wikipedia.org/wiki/Fallacies_of_distributed_computing https://en.wikipedia.org/wiki/Fallacies_of_distributed_compu...
- howard941 8y agoIt's not clear why some folks are dredging the self-driving cars, vehicle-to-vehicle, and vehicle-to-infrastructure use cases out for 5G but when the rubber hits the road I suspect vehicles will deploy with dedicated short range communications for the bits that must be low latency and 5G for ordinary cellphone use. The wiki page has some starting places for DSRC info. https://en.wikipedia.org/wiki/Dedicated_short-range_communications https://en.wikipedia.org/wiki/Dedicated_short-range_communic... . It is terrifying.
- aphextron 8y agoIt turns out car-to-car local networking is not really necessary. The use of 4G/5G networking + simulation based modeling and prediction gives great results. That’s what companies like Nexar [0] are doing. [0] https://www.getnexar.com https://www.getnexar.com
