Bluetooth is a wireless technology that allows data transfer between devices within close proximity. It operates on personal area networks that provide secure connections without risk of intrusion. Bluetooth is commonly used in devices like tablets, laptops, printers, and mobile phone headsets. While it has advantages like wireless capability and low power consumption, it also has limitations such as short range and lower data transfer rates. Bluetooth works by using small radio frequency chips in devices to transmit information wirelessly. It has features that provide security through fast frequency hopping, authentication, and encryption. Bluetooth is expected to become a widely adopted standard for wireless connectivity due to industry support and continual improvements to the technology.

3. WelcometotheWorld
of
Bluetooth!!!

4. Introduction:
 Bluetooth is a wireless technology for transferring
data between two devices that are in close proximity
with each other, and it has truly changed the world.
 The networks that it operates on are known as
Personal Area Networks (PAN), and these
connections are as secure as they come and offer no
risk of intrusion or theft of data.

5. Cont.
 This technology is also very popular in tablets,
laptops, netbooks, Bluetooth headsets for mobile
phones, printers, video game consoles, DVD
players and TV remotes.
 There are a number of other areas where it is
implemented as well and it is only a matter of time
before the technology really encapsulates our daily
lives.

6. History:
•Bluetooth Special Interest Group (SIG)
•Founded in Spring 1998
•By Ericsson, Intel, IBM, Nokia, Toshiba;
•Now more than 2000 organizations joint the
SIG

7. What is Bluetooth ?
• Bluetooth is a short-range wireless network
originally intended to replace the cable(s)
connecting portable and/or fixed electronic
devices. Such a network is also sometimes called
a PAN (Personal Area Network)
• Bluetooth is supposed to got it’s name from
Harald “Bluetooth” II, King of Denmark 940-981
• The concept was first patented by Ericsson.
Currently the Bluetooth trade mark is owned by
the Bluetooth SIG, a consortium of companies
having stake in Bluetooth

8. Advantages:
Wireless (No Cables)
No Setup Needed
Low Power Consumption (1 Milliwat)
Industry Wide Support

9. Disadvantages:
Short range (100 meters)
Small throughput rates
Data Rate 1.0 Mbps
Mostly for personal use (PANs)
Fairly Expensive

11. How Does It work ?
• Bluetooth is a standard tiny, radio frequency
chips that can be plugged into your devices.
• These chips were designed to take all of the
information that your wires normally send,
and transmit it at a special frequency to
something called a receiver Bluetooth chip.
• The information is then transmitted to your
device.

13. Comparison with other
wireless technologies
802.11 :
Has higher bitrate compared to Bluetooth . But
has higher power consumption. Basic a LAN
technology so not a direct competitor for Bluetooth
IrDA:
Low cost but require Line of sight. Only point
to point
HomeRF :
Competing technology. But current Bluetooth
is better positioned in market

14. Applications of Bluetooth:
Telephones
Headsets
Computers
Computer accessories
LAN peripherals
Multimedia Devices

15. Costs of Bluetooth:
 Uses low-cost transceiver microchips
 Estimated to cost around $4 to manufacture
 Operates on unlicensed radio spectrum
 No charge in communication between devices
 Only cost associated is for the actual product
that is enabled with Bluetooth

16. Bluetooth Security Features:
 Fast Frequency Hopping (79 channels)
 Low Transmit Power (range <= 10m)
 Authentication of remote device
> Based on link key (128 Bit)
 May be performed in both directions
 Encryption of payload data
> Stream cipher algorithm ( 128 Bit)
 Affects all traffic on a link
 Initialization
> PIN entry by user

17. Bluetooth’s Future:
The future of this technology becoming a standard is likely
With a strong industry pushing behind it, success is
inevitable.
Bluetooth will soon be known as Bluetooth 2.2 as they are
trying to develop the product to better fulfill the needs of
consumers.
Often, with new technology, early changes mean
reconstruction. Not With Bluetooth, instead, there will be
an improvement to the existing standard.

18. Conclusion:
We can conclude that Bluetooth plays a vital
role in the wireless technology. It is
considered as the cost effective and easy to
implement technology.
