Bluetooth
A wireless communication standard for connecting nearby digital devices to each other
In Simple Terms
Bluetooth is a wireless communication standard for connecting nearby digital devices without cables. Its range is short, but it uses very little power — making it ideal for small-battery devices like wireless earbuds and smartwatches that need to run for hours at a time. Wi-Fi is a similar wireless technology, but while Wi-Fi is built for sending large amounts of data over longer distances, Bluetooth specializes in directly pairing nearby devices with each other. From relaying mouse movements to streaming music, it's used in all kinds of everyday devices.
Behind the Name
The name "Bluetooth" comes from Harald Blåtand, a Danish king whose nickname meant "Blue Tooth." Just as the king united his divided nation under one rule, the name carries the vision of bringing all kinds of devices and communication standards together under a single wireless technology.
Take a Closer Look!
Bluetooth is a wireless communication standard for connecting nearby digital devices to each other.
Without any cables, devices can exchange data and transmit audio.
Its defining trait is that while its range is short, it uses very little power.
This makes it ideal for portable devices like wireless earbuds and smartwatches — gadgets that run on small batteries but need to last for hours.
Wi-Fi is another wireless technology, but the two serve different purposes.
Wi-Fi excels at sending large amounts of data over longer distances and is mainly used to connect computers and smartphones to the internet.
Its higher speeds make it well-suited for things like streaming high-definition video.
Bluetooth, on the other hand, doesn't connect directly to the internet — it's built for pairing nearby devices directly with each other.
While it isn't as fast as Wi-Fi, it has plenty of bandwidth for tasks like relaying mouse movements or playing music.
It's an essential technology that frees all kinds of everyday devices from the hassle of tangled cables.
