Re: "fire alarms that can call the fire service."
Obvs not as important as as a fire alarm, but I recently came to the same conclusion for my home network.
After lots of money and kit over the years, I am back full circle with believing that in general wireless is bobbins and for my own setup, the cable is queen.
I've been finding for domestic use that even modest powerline kits have blown away the frustration and restored something like a usable network.
My one regret is not coming to this denouement earlier, and running CAT5e through the house while everything was apart for the heating going on. Live and learn I guess.
