Vehicle fobs are usually not in the 2.4Ghz range, they're usually in the 300-500mhz range.

But yes, there's a lot of assumptions and usually it's right, but it can be wrong also.

Also, fun fact, microwave ovens use very high power 2.45Ghz. so they can do this by simply rigging a microwave to turn on when the door is open, then pointing it at your house at a safe distance, like across the street.

Most companies that make outdoor stuff generally avoid 5Ghz because it's a regulatory nightmare. Some countries allow it, others only allow certain frequencies, others only allow certain frequencies up to a certain power level, others basically don't allow it at all. So all your fancy door bell/cameras/whatever that you connect outside your home are all going to be limited to 2.4 GHz with is basically universally available internationally (it's an ISM band, while the wifi 5ghz is a UNII band).... So yeah, good luck everybody!

Also wired cameras and such exist, they're a pain to install, but they work well, and the market for other outdoor network connected things is extremely limited.... Things like doorbells.

I hate putting static objects on wifi, even something like my TV, I want it wired simply because it never moves and there's no reason to use it wirelessly. I can run a wire to it once and even if I upgrade the TV, the wire still works. To explain this a little more, I'm an IT administrator and I have a specialty in wireless networking. As tersely as I can: more stuff on the WiFi makes it slow, so if something can be wired, it should be wired. Obviously there are things that are not well suited to it, like cellphones and laptops, but pretty much everything else should be wired. TVs, set top boxes, desktop computers... Basically anything that can be wired, that doesn't regularly move around.... Wired. This extends to cameras, doorbells, gdo's....

This frees up wireless bandwidth for devices that are obligated to use it, like your phone and tablet.

I've seen a lot of network issues resolved by simply plugging in everything that's practical to plug in, even if the device having the issue wasn't one of the things plugged in.
