INTRODUCTION TO BLUETOOTH TECHNOLOGY
[attachment=49931]
Definition of Bluetooth
Bluetooth is a short range (10-100 m) and low-cost wireless network system to replace cables and give RF connection between consumer devices.
OVERVIEW
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 link mobile phones & accessories.
5 companies (Ericssn,Nokia,IBM,Toshiba & Intel)joined to form the Bluetooth Special Interest Group (SIG) in 1998 named.
First specification released in July 1999.
DETAILS
Uses the radio range of 2.45 GHz
Theoretical maximum bandwidth is 1 Mb/s
Several Bluetooth devices can form an ad
hoc network called a “piconet”
– In a piconet one device acts as a master (sets
frequency hopping behavior) and the others as
slaves
– Example: A conference room with many
laptops wishing to communicate with each
Other
