Bluetooth is a low-power, short-range radio technology that connects two electronic devices within a maximum radius of 33 feet to share data.

This path-breaking technology is named after the Norwegian King — Harold ‘Bluetooth’ Gormsson — whose bad tooth got him the name ‘Bluetooth’.

Bluetooth devices connect when placed in close proximity, via radio waves emitted by computer chips inside them. These chips are activated when you switch on Bluetooth.

The two devices then communicate over a short-range network of Bluetooth devices called piconet. These networks enable devices to connect instantly.

Scanning devices detect inquiries from other gadgets and demand information on the nature of the request.

Bluetooth uses algorithms called codecs to encode and decode data into smaller packets, making it easier to transmit different depths of data.

Some of the popular types of codecs include SBC, AAC, aptX, and LDAC — these vary in terms of power usage, transfer rates, audio quality, stable connection range, etc.

In 2008, only 5% of mobile devices were Bluetooth-enabled. Today, more than 95% of mobile devices support Bluetooth connections.
