Why is Bluetooth called Bluetooth?
Surprisingly, the name dates back more than a millennia to King Harald “Bluetooth” Gormsson who was well known for two things: Uniting Denmark and Norway in 958. His dead tooth, which was a dark blue/grey color, and earned him the nickname Bluetooth.
Which Wi-Fi channel has longest range?
If you have a 5 GHz router, consider using 20 MHz for maximizing the amount of non-overlapping channels. Regardless of using 2.4 GHz or 5 GHz, 20 MHz leaves you with the largest amount of non-overlapping channels. 20 MHz makes sense for high-density deployments and areas where interference is a major problem.
