Welcome to Bluetooth 101

Bluetooth is everywhere nowadays. It’s a word we hear all the time and is in millions of products we use everyday, including headsets, cellphones, laptops, portable speakers, etc. But how much do we actually know about Bluetooth? Here are seven facts you may not know.


1. First things first... why is it called Bluetooth?

Contrary to popular belief, Bluetooth is not named after a big blue tooth. That would be weird. It is actually named after a Viking king from medieval Scandinavia (also pretty weird). His name was Harald Bluetooth and was famous for uniting parts of Denmark and Norway into one nation.


2. What's up with the logo?

Speaking of good ole’ King Bluetooth, the logo was also created with him in mind. For those who aren't fluent in every language in history, the symbol is Harald Bluetooth’s initials written in Scandinavian runes.

3. So how does it actually work?

Bluetooth uses radio waves instead of wires or cables to connect to devices. Unlike infrared, radio waves can pass through walls and other objects.



4. Bluetooth is actually hardware and software.

How can it be both, you ask? Well, each device contains a Bluetooth chip with a tiny radio and uses software to help it communicate with other devices.


5. Bluetooth can connect to multiple devices.

Bluetooth can connect up to seven devices. This works by creating one of the devices as the master device. The master coordinates all the communication to the rest of the devices. However, in most cases, there can only be one live Bluetooth connection.


6. The range is much bigger than it used to be.

The earliest versions of Bluetooth would range up to 10 ft. However, the newer versions can now communicate up to 100 ft.


7. It's really popular.

In 2008, only 5% of mobile devices were Bluetooth enabled. Now, 95% of mobile devices use Bluetooth.




It’s safe to say Bluetooth is going to be around for awhile. But you never know, maybe in ten years there will be greentooth...
