> For a lot of homes, that's enough to provide good-enough internet throughout the building.
It often isn't - it's just magic like TCP/etc that is doing its job and making it feel that way for bulk non-interactive transfers. But get those people on a Zoom call or anything real-time and it'll be painful (double pain if they've subsequently got terrible bluetooth headsets and/or accidentally use their laptop's internal mic).
Doesn't help stupid ISPs split their 2.4GHz and 5GHz bands on separate SSIDs so now devices can't switch automatically and you've either got people constantly hogging the 2.4 band or barely trying to hang onto the 5GHz one in conditions where falling back to 2.4 would be appropriate.
I wouldn't be surprised if they did this to lower the support workload, since I have several 2.4Ghz devices that fail to connect to WiFi at all if I put both bands on the same SSID. I intentionally separated them for that reason and portable devices like phones know how to switch between multiple SSIDs based on signal strength anyway.
>Also, crashes are statistically rare events on arterial and local roads, so it can take years to accumulate sufficient data to establish a valid safety profile for a specific road segment.
That is exactly what this article is about.
