I finally saw the numbers on cellular vs. radio alarm signaling failure rates
Was reading a security trade magazine last week, and it said cellular alarm signals fail about 5% of the time during power outages, while old radio paths only drop like 1-2%. That surprised me, because I always figured cell was more reliable since it's newer. But I guess radio towers have backup batteries and cell networks get jammed up. What side do you guys lean toward for critical sites like banks or hospitals?

Wow, this actually flips my whole thinking on its head too. I honestly used to be all about cellular because it seemed more modern and I figured the tech had to be better by now. But whenever I thought about it, I just assumed carriers had everything covered. You're right though, when the power goes out in a big storm, everyone's phone becomes a brick or a congestion monster. I never considered that radio signals don't have to compete with millions of people checking weather alerts and calling family. For something like a bank or hospital where seconds matter, giving up that guaranteed dedicated path feels risky. Yeah, I'm definitely leaning toward radio now for the really critical stuff.

That "5% failure rate during power outages" figure jumps out at me because it's probably worse than the raw numbers show. Cell towers do have backup batteries, but when you've got a widespread outage, everyone and their brother is camping on their phone, and the network gets congested fast. The real kicker is that radio signaling usually uses a dedicated frequency, not a shared consumer network, so it doesn't compete for bandwidth with people streaming Netflix during a storm. For something like a bank or hospital, I'd take the slightly older tech that's got its own lane over the modern stuff that's fighting for space with everyone else.

Half a million people fighting for cell signal during a storm and you wonder why alarms drop? I saw a study once that said during Hurricane Sandy, cell networks in some areas saw failure rates over 30% for alarm signals specifically. That 5% figure must be an average on a good day. @luna261 made a good point about dedicated paths too. Radio is basically a private lane while cellular is the interstate at rush hour with everybody honking. For banks and hospitals with life safety stuff, I'd take the old reliable 1% failure rate over the shiny new 5% any day.
