Bluetooth technology was developed in 1994 by Ericsson in Sweden to eliminate the need for proprietary cable connections between devices. It uses short-range radio transmissions to allow wireless connections between nearby electronic devices like phones, computers, and other devices. The Bluetooth Special Interest Group was formed in 1998 to develop specifications so that Bluetooth devices from different manufacturers can interoperate. Bluetooth technology is now widely used to wirelessly connect a variety of consumer and industrial devices over short distances.

1. BLUETOOTH
TECHNOLOGY

2. HISTORY
• Bluetooth wireless technology (BWT) was developed in 1994 at
Ericsson in Sweden.
• The original purpose of BWT was to eliminate the need for
proprietary cable connections between devices such as PDAs and
notebook PCs.
• Although infrared communication existed at the time, it required line-of-
sight contact.
• Therefore, Ericsson chose to use an inexpensive, low-power radio
built into each device, making it possible to wirelessly connect
devices through walls and other nonmetallic materials.
• After Ericsson began work on BWT, the concept blossomed into a
radio technology that simultaneously connects several devices in a
wireless personal area network (WPAN).

3. •Because of the unlimited potential of BWT, the Bluetooth Special Interest
Group (SIG) was formed in 1998 to develop the Bluetooth Specification IEEE
802.15.
•The specification standardized the development of BWT-enabled devices so
that devices from different manufacturers can work together.

4. The symbol of Bluetooth
• As famous as the name is the Bluetooth
symbol.
• Bluetooth's logo combines the representation
of the Nordic runes Hagalaz (transcribed by
'H') and
• Berkana (transcribed by 'B') in the same
symbol.
• This is, HB like Harald Blåtand the king

6. WHAT IS BLUETOOTH
 Bluetooth is a standard used in links of radio of short scope,
destined to replace wired connections between electronic devices
like
 cellular telephones
 Personal Digital Assistants (PDA),
 computers, and many other devices.
• Bluetooth technology can be used
 at home,
 in the office,
 in the car, etc.
• This technology allows to the users instantaneous connections of
voice and information between several devices in real time.
• It assures protection against
 interferences and
 safety in the sending of information.

7. What Is Bluetooth?
• Bluetooth is a WPAN technology.
• Accordingly, its radio characteristics include:
 low power
 Short range and
 medium transmission speed.
• These characteristics influence:
 what devices will incorporate Bluetooth
 how users will experience it and
 what it will be used for.

8. •First its low power consumption makes Bluetooth ideal for small, battery-powered
devices like mobile phones and Pocket PCs that have little energy
to spare.
•Second, Bluetooth’s short range (10 meters) is ideal for the concept of
“personal operating space” and integrates the notion of using devices
carried or worn on the body or otherwise located within immediate reach.
Bluetooth’s transmission speed of 800 Kbps works well for transferring small
to medium-sized files.
•A Bluetooth WPAN involves up to eight devices located within this 10-
meter personal operating space that unite to exchange information or share
services.
•Because it can be done spontaneously according to immediate need, it is
known as “ad hoc networking.”
•And because a WPAN involves directly networking between different
points, without the use of network infrastructure, it is also referred to as a
“point-to-point network.”

9. Who will use Bluetooth?
 four categories of users:
 professional and field workers
 Technology-savvy electronics consumers
 Industrial and retail
 office workers.

10. Where will Bluetooth be used?
• It can be used absolutely anywhere that at least two Bluetooth-devices
share a 10-meter range.
• This is possible because Bluetooth is designed for direct point-to-point
networking between devices and does not require proximity
to infrastructure stations like signal towers or access points.
• So for someone who possesses at least two Bluetooth devices, that
person can use Bluetooth wherever he/she chooses to bring those
devices.
• This freedom to roam will especially be important for traveling
workers who need access to data communications and corporate
data wherever they happen to be; locations will vary from a client’s
office or airport gate to a remote field site or restaurant.

11. How will Bluetooth be used?
A car rental employee could use a Pocket PC to scan a VIN.
•at a car rental facility, an employee could use a Bluetooth-enabled
Pocket PC equipped with a bar code scanner to scan a
Vehicle Identification Number (VIN), enter mileage and fuel
data, then instantly transmit a receipt to a Bluetooth-enabled
portable Printer worn on the hip.
•Additionally, Bluetooth is an ideal solution for connecting
mobile audio devices.

12. •Predominantly a WPAN technology, Bluetooth will primarily be used for
cable replacement.
•Bluetooth eliminates the need to carry or handle bulky cables, frees up
your ability to move around while using devices together, and lets you
easily connect devices separated by physical impediments like walls.
•Bluetooth is an ideal solution for connecting the increasing number of
devices designed to be held in the hand or worn on the body.

13. What types of devices will incorporate
Bluetooth?
• The largest Bluetooth market will be mobile phones, with over 70%
of mobile phones expected to be Bluetooth-enabled by 2006.
• Backed(support) by manufacturers like Ericsson, Intel, Microsoft,
Motorola, Nokia, and Toshiba, Bluetooth will also appear in
consumer gadgets like PDAs, notebook computers, computer
games, headsets, alarms, smart home control units, TVs, VCRs, and
auto PCs.
• For retail, industrial, and office applications, Bluetooth will surface
in mobile computers, bar code laser scanners, cash registers, ending
machines, GPS receivers, slide projectors, printers, digital cameras,
digital camcorders, test and measurement equipment, and LAN
access points.

14. •Originally developed by Ericsson to eliminate the cable between a
headset and mobile phone, Bluetooth features audio channel capability.
•In Europe, Asia, and Africa, mobile phones based on GSM technology are
popular.
•For example, you could use your Bluetooth-enabled mobile phone at a
Bluetooth-enabled vending machine to charge your account and buy a
drink.

15. USAGE MODEL EXAMPLES
• Wireless headset: The leading adoption of Bluetooth will initially be
in the area of mobile phones.
• Nearly every major mobile phone manufacturer has already
released Bluetooth-enabled models of their popular phones.
• The driver for this adoption is the ability to use a wireless headset
with the phone.
• The radio frequency energy emitted by a Bluetooth wireless
headset is a fraction of that emitted by a mobile phone.
• Additionally, the convenience of being cordless means the phone
can be used even if it is in a briefcase or the trunk.

16. •INTERNET BRIDGE: Bluetooth wireless technology can be used to allow
a mobile phone or cordless modem to provide Dial-Up Networking (DUN)
capabilities for a PC, allowing it to connect to the Internet without a
physical phone line.
•This enables a laptop to automatically utilize the user’s nearby cell phone
to dial and connect to a dial-up service.
•The user doesn’t need to touch the phone, which might be in a briefcase
or coat pocket.
•FILE EXCHANGE: The ability to perform peer-to-peer file exchange
without the presence of a network infrastructure has many advantages.
•For example, a salesperson may choose to share the contents of an
electronic slide presentation with the audience.
•Bluetooth enables the automatic detection of any Bluetooth devices in
the room, enabling the transfer of all selected files.

17. Synchronization: Bluetooth allows for data synchronization between
devices.
For example, a desktop computer that is Bluetooth enabled can
wirelessly synchronize its contact list, task information, calendar, etc., to
a user’s phone, PDA, or notebook.
Several Bluetooth- based synchronization models already exist for both
Pocket PC and Palm-based PDAs.
Printing: HP is making printers and notebooks with embedded
Bluetooth technology.
Bluetooth-enabled devices can automatically detect Bluetooth-enabled
printers in their area and wirelessly send documents to the printer
without going through lengthy network and printing setup processes.
Mobile users who frequently visit remote offices will find Bluetooth
printing a significant improvement in convenience to their current
experience.

19. What does it mean to be Bluetooth-enabled?
• A Bluetooth-enabled device has a radio that operates at Bluetooth
frequency (2.4 GHz) and
• software that manages the connection data flow and security to
adhere to the Bluetooth Specification.
• Bluetooth products need certification from the Bluetooth SIG, which
ensures interoperability with other Bluetooth products.
• Between the principal characteristics, must be named the hardiness,
low complexity, low consume and low cost.
• The Bluetooth is a small microchip that operates in a band of
available frequency throughout the world.
• Communications can realize point to point and point multipoint.

21. •Bluetooth is officially adopted and The Bluetooth Special Interest Group
(SIG) is formed.
•The SIG welcomes its 400th member by the end of 1998
•The SIG grows from 400 members to more than 10,000

communication information over a large spectrum with low energy
requirements.
•Has been proposed to fulfill this need, and in 2007 the Bluetooth Special
Interest Group (SIG) announced its intensions to incorporate Ultra
Wideband as ad-on high-speed radio technology in the Bluetooth 4
release due 2010/11.
•As a relatively new player, UWB needs to align itself with established
technologies in order to gain momentum, prompting the WiMedia Alliance
in March 2009 to announce its intention to disband and transfer all current
and future specifications to the Bluetooth SIG, Wireless UWB Promoter
Group and USB Implementers Forum.

27. •The Bluetooth 3.0 specification released in April 2009 incorporates an
Alternative MAC Feature.
•Which enables the use of an alternative high-speed radio for
transporting Bluetooth profile data.
•Whilst the Bluetooth radio is still used for device discovery and
connection setup.
•Currently only supporting 802.11 (Wi-Fi), providing Bluetooth with
increased transfer rates of 24 Mbps over longer distances, this new AMP
feature paves the way for incorporation of the low-power high-bandwidth
UWB radio technology.
