 What is Bluetooth?  Bluetooth is a short-range wireless communications technology.  Why this name?  The 10th century Danish King Harald Blatand  When did this appear?  1994 – Ericsson study  5 companies - (SIG) in  First specification- in July 1999.

 the various pieces and parts of the systems make up a community of electronic devices.  Different ways that electronic devices can connect to one another:  Component cables  Electrical wires  Ethernet cables  Infrared signals  To reduce complexity - bluetooth

.

 “Pair”  “Search”  “Connect”  “Transfer data”

 A bluetooth device: adapter.  Link management protocol: peer-to-peer message exchange.  Service delivery protocol : join a piconet  Bluetooth GlobalID : exchanged  profiles matched and a connection is setup  uses frequency hopping in timeslots

 support wireless point-to-point and point-to- multipoint  Point to Point Link network formed by a Master and one or more slaves  Piconet(network formed by a Master and one or more slaves ) ms s s s m

1) completely wireless 2) surprisingly affordable 3) easy to use 4) work with other Bluetooth enabled devices 5) Low interference 6) Lower energy consumption 7) pairs with compatible devices & share info 8) creating a Personal Area Network (PAN) 9) emerging technology- constantly offering better features and services. 10) many fads come and go, Bluetooth, however, seems to be in it for the long haul.
