Bluetooth Goals & Vision :
23 December, 2009 7 Bluetooth Goals & Vision Originally conceived as a cable replacement technology Short-Range Wireless Solutions Open Specification Voice and Data Capability Worldwide Usability Other usage models began to develop: Personal Area Network (PAN) Ad-hoc networks Data/voice access points Wireless telematics
Overview of Bluetooth History :
23 December, 2009 8 Overview of Bluetooth History What is Bluetooth? Bluetooth is a short-range wireless communications technology. Why this name? It was taken from the 10th century Danish King Harald Blatand who unified Denmark and Norway. When does it appear? 1994 – Ericsson study on a wireless technology to page link mobile phones & accessories. 5 companies joined to form the Bluetooth Special Interest Group (SIG) in 1998. First specification released in July 1999.
