3. Definition of 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 network.
4. History of Bluetooth
The word “Bluetooth” is taken from the 10th century Danish King
Harlard, who unified Scandinavian people tribes into a single
kingdom.
Bluetooth was named because –
Bluetooth technology was developed in Scandinavian.
Bluetooth technology was able to unite different industries such as
cell phone, computing and automotive markets.
The Bluetooth specification was first developed in 1994 by Ericsson
Mobile Communication Ltd.
5 Companies (Ericsson, Nokia, Intel, Toshiba, & IMB) joined to form
Bluetooth Special Interest Group (SIG) in 1998.
In 1999, first specification of Bluetooth i.e. Bluetooth 1.0 is released.
5. Characteristics of Bluetooth
Bluetooth stands for Short-range transmission of digital
voice and data.
Frequency Range: ISM (Industrial, Scientific and Medical
Radio Bands) 2200MHz – 2400 MHz
Bluetooth used a Radio Technology called Frequency
Hopping Spread Spectrum.
Vanishes the need of chord and wire.
Range of Connection : 10 m – 100 m.
Supports data rate of : 1Mb/s.
6. Characteristics of Bluetooth
There are three classes of Bluetooth devices.
Class 3 Radio: have range up to 1 meters or 3 feet.
Class 2 Radio: most commonly found in mobile
devices – have range of 10 metes or 30 feet.
Class 1 Radio: used primarily in Industrial use
cases – have range of 100 meters or 300 feet.
7. Working of Bluetooth
Uses short range of RF spectrum at 2.45 GHz.
Uses quick frequency hoping packet switch Protocol.
Transceiver has a unique 48 bit address.
Uses IEEE 802 Standards.
Several Bluetooth devices can form an AD-HOC
Network called a “PICONET”.
In PICONET, one device is act like a master (sets
frequency hoping behavior) and the others as slaves.
9. Working of Bluetooth
More than one PICONET is called SCATTERNET.
Up to Eight devices are allowed in PICONET.
Each PICONET is identified by a different
frequency hopping structure.
Connections can be made up to 10 meters or can
be extended to 100 meters.
Power consumption is 0.3 mA.
10. Security Features of Bluetooth
Bluejacking
Funny type message sent to people’s Bluetooth enabled device without owner
permission.
Bluesnarfing
Hacker’s gaining access to people Bluetooth enabled device mainly to made some
harm.
Allows hackers to send message, make phone calls etc.
The hacker to be within 30 ft rage
To avoid set your phone to non-discoverable mode
Bluebugging
Advanced level of hacking with technology use
Hacker’s gaining access to people Bluetooth enabled device mainly to made some
harm.
Allows hackers to send message, make phone calls etc.
Also 30 ft range
11. Advantages of Bluetooth
Bluetooth devices are wireless
Bluetooth technology is inexpensive
Bluetooth is automatic
Share voice and data
Low energy consumption
Accessible from anywhere
14. Future of Bluetooth
Radio2 Working Group
• Working to overcome bandwidth, interference, and
connection setup issues while remaining
compatible with current radio
Other Working Groups
• Audio/Video, Car, Co-existence, ISDN, Local
Positioning, Personal Area Networking, Printing
Study Groups
• Industrial Automation
15. Conclusion
A new global standard for data and voice
Eliminates Cables .
Low Power, Low range, Low Cost network devices.
Bluetooth seems to have a bright future after reviewing its benefits and wide
use.
Further improvements are planned to be made in
– Data Rates
– Power Reduction
– Range
