Fuck… I got this Amber alert today while playing videogames with my kid… I dismissed it, told him it was just an alarm, and then got another later saying it was cancelled, “check local news sources for details”. I assumed it was what I thought a lot of them are: domestic dispute leads to a parent driving off with the kids and the other parent calling the cops. This is way more grim than I thought
5G cellular is high bandwidth but very short range, so yeah they need that kind of density to maintain coverage. They installed them in a street near me and they’re placed every couple of blocks. It’s useful to think of the usual WiFi router at home: you can set up 2.4g and 5g access points. The 5g ones are faster, but have shorter range and you need to use the 2.4g one if you’re far from the router
