But it's hard to do even locally, let alone at scale. I've been around long enough to remember winmodems and the difference between real RAID cards and the fakeraid shipped on many motherboards today. SDR radio receivers are fantastic, within their capability (which expands every year). So parts of your system make a lot of sense, but other parts seem to require perfect knowledge of the environment, and that has never been able to work even on wired networks, and RF is much uglier David Lang
