bluetooth technology
TRANSCRIPT
History• 1998 - Bluetooth technology is officially introduced and the BLUETOOTH
SIG is formed. Bluetooth technology's intended basic purpose is to be a wire replacement technology in order to rapidly transfer voice and data.
• 1999 - Bluetooth 1.0 Specification is introduced.• 2003 - The BLUETOOTH SIG overhauls the Bluetooth Core Specification
with the announcement of Version 2.1.• 2004 - Bluetooth Version 2.0 + EDR (Enhanced Data Rate) is introduced.• 2005 - Devices using Version 2.0 + EDR begin to hit the market in late
2005.• 2007 - Bluetooth Core Specification Version 2.1 + EDR is adopted by the
BLUETOOTH SIG.• 2009 - Bluetooth Core Specification Version 3.0 + HS (High Speed) is
adopted by the BLUETOOTH SIG.
Bluetooth Network Topology• capable of point to point & point to multi-point connections
• Piconet:
° a master device
° one to seven active slave units
° a piconet channel
• Scatternet:
° a group of piconets, up to maximum of ten
° a way of connecting a device to multiple masters
° Full-duplex rate of more than 6Mb/s.
Privacy/Security
• Very Important.• Don’t want data to be shared.• Security not great.– Pairing security.
Reliability
• What it really means?• Which device are you connecting to?• How large is the file?• Which version are you using?• Have the two devices been connected before?
Ease of Use
• Very easy to use.• Connection is fast and simple.• More devices are Bluetooth capable.• Auto recognition.
Future
• Diverse applications with Bluetooth.• Faster transfer rate.• Stronger connection.• Longer distance.
Conclusion
• Few flaws– Security
• Good for short transfers– Limitations on file size– Limitations on distance
• Convenient – Faster – More simple than flash drive
