Bluetooth is a wireless technology standard for exchanging data over short distances (using short-wavelength radio transmissions in the ISM band from 2400–2480 MHz) from fixed and mobile devices, creating personal area networks (PANs) with high levels of security.

3. What is Bluetooth?
Bluetooth is a short range(10-100m) and low-
cost wireless network system to replace
cables and give RF connection between
consumer devices.
5. HISTORY
The word ‘Bluetooth’ is taken from the 10th
century Danish King Harald Bluetooth,he
had been influential in uniting Scandinavian
tribes into a single kingdom.
Bluetooth was so named because:
1) Bluetooth technology was developed in
Scandinavia.
2) Bluetooth technology is able to unite differing
industries such as the cell phone, computing,and
automotive markets.
6. TECHNOLOGY REVIEW
Bluetooth uses a radio technology called
frequency -hopping spread spectrum.
Supports data rate of 1 Mb/s(originally).
The Bluetooth specification are developed
and licensed by the Bluetooth Special Interest
Group(SIG).
8. Bluetooth Characteristics:
Allows up to 8 devices to communicate in a
localnetwork called a Piconet, also known as
a PersonalArea Network or PAN
Because of its low power consumption, its
range islimited to 10 m.
However, range can be increased to 100 m
by employing a scatternet topology or a
higher powered antenna.
9. Classes Of Bluetooth:
Three classes of bluetooth devices:
1) Class 3 radios: Have a range of upto
1 meter or 3 feet.
2) Class 2 radios: Most commonly found
in mobile devices-have a range of 10 meters
or 30 feet.
3) Class1 radios: Used primarily in industrial use
cases-have a range of 100 meters or 300 feet .
10. Bluetooth Enabled Devices:
Laptop
Cellular phones
Personal Digital assistants
Headsets
Printers
Keyboards
GPS,etc
Major use in consumer electronics
11. Bluetooth Details:
Uses the radio range of 2.45 GHz.
Theoretical maximum bandwidth is 1 Mb/s.
Several Bluetooth devices can form an ad
hoc network called a “piconet”.
-In a piconet one device acts as a master (sets
frequency hopping behavior) and the others as
slaves.
- Example: A conference room with many laptops
wishing to communicate with each other.
14. The Bluetooth technology is divided
into two specifications:
Core Specification
-Deals with the lower
layers of the
architecture and
describes how the
technology works.
Profile Specification -
Focuses on how to build
interoperating devices
using the core
technology.
15. Competting Technologies:
Infrared Data
Association(IrDA):synchronization, link
between a phone and a laptop…
– Less flexible than Bluetooth, need of a line of
site.
– Comparable data rate.
16. Wi-Fi (WLAN) : Wireless LAN access
– Far higher bandwidth and data rate
than Bluetooth.
– Higher power consumption than
Bluetooth.
– Requires infrastructure investment.
20. FUTURE OF BLUETOOTH:
Bluetooth has a good future ahead
because it meets a basic need of
connectivity.
Latest version of Bluetooth are
improving both its security and
capabilities.
21. New versions of Bluetooth technology
will meet the high-speed and large
range.
Many companies are designing
impressive bluetooth applications in
demand.
22. CONCLUSIONS:
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 :
1-Data rates 2-Power Reduction 3-Range
