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.
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.
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.
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.
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.
Working of Bluetooth
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.
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
Advantages of Bluetooth
Bluetooth devices are wireless
Bluetooth technology is inexpensive
Bluetooth is automatic
Share voice and data
Low energy consumption
Accessible from anywhere
Disadvantage of Bluetooth
Low data rate.
Short range.
Low security.
Interference with other devices.
Applications of Bluetooth
Laptops
Cellular phones
Personal digital assistants
Headsets
Printers
Car
GPS etc…
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
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
