2 What is this so called Bluetooth? Bluetooth is a short-range and low power wireless technology originally developed for exchanging data over short distances from fixed and mobile devices, creating personal area networks. It was originally conceived as a wireless alternative to data cables

3 Back in Time 2 The word "Bluetooth" is taken from the 10th century Danish King Harald Bluetooth, he had been influential in uniting Scandinavian tribes into a single kingdom. Bluetooth was named so because this technology is able to unite differing industries such as the cell phone, computing, and automotive markets.

4 Bluetooth was invented in 1994 by Ericsson. The company later started working with a larger group of companies called the Bluetooth Special Interest Group, or "SIG," to develop the technology into what it is today. Timeline

5 In 1999, Bluetooth 1.0 was released In 2004, Bluetooth 2.0 was released. In 2009, Bluetooth 3.0 with enhanced data rate (EDR) is released. In July 2016, Bluetooth 5.0 Core Specification is released. Timeline

7 How does Bluetooth work? When device is put in discoverable mode, each device only knows about itself.

8 How does Bluetooth work? INQUIRY identifies who else is in the range

9 How does Bluetooth work? PAGING creates a link between a device

10 How does Bluetooth work? EXPANDING creates link between following devices
