Who invented Bluetooth and how does it work?



Bluetooth works by the simple principle of sending and receiving data in the form of radio waves.


       Bluetooth is a method of short-range wireless communication between electronic devices that harnesses the power of radio waves



         But if the radio spectrum stretches from 30Hz to 300GHz (the lower the frequency, the longer the range), Bluetooth operates at 2.4GHz which gives it the right balance between range and data quality.





         It was conceived by a Dutch engineer Dr Jaap Haartsen at the Swedish mobile giant Ericsson in the 1990s.





        In 1998 the Bluetooth Special Interest Group (SIG) was formed to develop and promote the technology.


         The group released Bluetooth 1.0 in 1999 and a year later it began to be used in mobile phones and desktop PCs, making its way into laptops and printers in 2001.







   
         In the mid-2000s the Bluetooth headset which allowed people to communicate hands free -
 became a common sight.
