BLUETOOTH
 Bluetooth is an open wireless
 technology standard for exchanging
 data over short distances from fixed
 and mobile devices creating PAN’s
 with high level security.

 Created by ERRICSON in 1994

 Bluetooth started as a code name for
 association when it was formed. It
 evolved from the epithet of Danish
 King Harold who united many
 warring fractions of land together.
Blue tooth is a packet based protocol with a master slave architecture.

Specifications for Bluetooth are developed by Bluetooth Special Interest
Group (B-SIG).
B-SIG was formed in 1998, Head Quarters : Washington

The Bluetooth SIG includes Promoter member companies Ericsson, Intel,
Lenovo, Microsoft, Motorola, Nokia, and Toshiba, and more than 13,000
Associate and Adopter member companies.
Integrates telecommunication, computing , networking & Consumer
electronics Industry.
Mission Statement : Strengthen the Bluetooth brand by empowering SIG
members to collaborate and innovate, creating the preferred wireless
technology to connect diverse devices.

TECHNICAL FEATURES
Network Arrangements

 Bluetooth networks can be either point to point
            or point to multi-point.

 Any unit in a Pico net can establish a connection
    to another Pico net to form a scatter net.

  Bluetooth arrangements are only between two

         Bluetooth characteristics
It separates the frequency band into hops. This spread spectrum is
used to hop from one channel to another, which adds a strong
layer of security.
Up to eight devices can be networked in a Piconet.


Devices do not need to be pointed at each other, as signals are
Omni-directional

Both synchronous and asynchronous applications are supported,
making it easy to implement on a variety of services, such as voice
and internet.
Governments worldwide regulate it, so it is possible to utilize the
same standard whenever one travels.
COMPETING TECHNOLOGIES
   COMPETING TECHNOLOGIES

• Wireless Lan
WLAN based on IEEE 802.11b standards are
used to replace the wired LAN.
Adv: Transmission capacity and the number
of simultaneous users are high.
Dis: Compared to Bluetooth they are more
expensive, consume more power and
requires large hardware setup making them
unsuitable for smaller devices
     BLUETOOTH IN THE FUTURE
• The Bluetooth technology is expected to
  provide greater bandwidth and distances.

• Hence increasing potential platforms and
  applications used in personal area network
  marketplace.
     BLUETOOTH IN THE FUTURE
• This technology was used in as many as 670
  million products.

• Based on the request of Bluetooth SIG (Special
  Interest Group), the range and speed of
  Bluetooth connectivity is expected to increase.
               • In addition to improving safety as a
                 result of eliminating clutter of wire

                 offers you many convenient
                 advantages.

               • Bluetooth technology is cheap for the
                 companies to implement, which

                 results in lower the overall
 technology
                 manufacturing costs. These savings
          is
                 are then passed on to consumers. The
Inexpensive
                 end result the Bluetooth devices are
                 relatively inexpensive.
               • When two or more Bluetooth devices
                 enter a range (Up to 10 meters) of one

                 communicate without you having to do
                 anything.

               • Bluetooth uses low power signals. As a
 Low energy      result, the technology requires little
consumption      energy and will therefore use less battery
                 or electrical power.
    Share    • Bluetooth standards allows
Voice and      compatible device to share both

Accessible   • Though Bluetooth device has a
