TIL why Bluetooth is called Bluetooth:

> It was the epithet of King Harald Bluetooth, who united the disparate Danish tribes into a single kingdom; Kardach chose the name to imply that Bluetooth similarly unites communication protocols. [https://en.m.wikipedia.org/wiki/Bluetooth#Name_and_logo]

Another thing, not mentioned in the article, is that microwave ovens tend to interfere with Bluetooth in my experience.



Not just your experience. I worked for a company that made a lot of wireless devices. We had a pretty open-plan office and learned not to test anything around lunchtime.

Seriously. There were many times that I was working on something that suddenly had a spike in the receive failure rate and I'd look at the time and realize that somebody was heating up their lunch in the microwave.

And WiFi. And anything else that might happen to operate in the 2.4 GHz ISM band (like some cordless phones, back in the day).


It absolutely does. Especially if folks are in the habit of opening the door before the microwave shuts itself down.
