Today, while remotely accessing my home server, I noticed that the network was a bit slower than usual. It turns out, there’s no 5G connection and only an LTE connection with another cell tower more far away. I checked the service provider’s website and there’s actually a problem with a base station nearby.
But this also shows, that, maybe, a cellular connection might improve the uptime given that there’s the fallback to other cell towers. The VDSL connection has no such fallback. But, of course, a cellular connection is more vulnerable due to weather conditions etc.
