4. Bluetooth technology:
 Bluetooth is a wireless technology
used for exchanging data over short
distances using radio waves.
 Bluetooth technology eliminates the
need for numerous cable
attachments.
 Bluetooth communicates between
devices within a range of 10 meters.

5. Bluetooth(cont)
 Bluetooth operates in the range of
2400–2483.5 MHz.
 this technology enables users to
easily connect a wide range of
computing & telecommunication
devices.

6. History:-
 This tecnology was officially introduced in
1998 and its basic purpose was to be a wire
replacement technology in order to rapidly
transfer voice and data.
 Bluetooth is managed by the Bluetooth
Special Interest Group which has more than
20,000 member companies in the areas of
telecommunication, computing, networking,
and electronics.

7. How it works:
 Bluetooth is a high speed,low power
microwave wireless link technology
designed to connect communicating
devices,connections can be point to
point or multipoint.
 Unlike infra-red, bluetooth technology
does not require any line of sight
positioning of connected devices like
infra-red.

8. How works(cont)
 Two bluetooth products can exchange
their addresses and capabilities just
after coming within the range of 10
metres.
 can be extended 100 metres by
increasing power,it supports data
speed of up to 721 kbps.

9. How works(cont)
 The bluettoth modules can be either bulit into
electronics devices or used as an adaptor

10. How works(cont)
 Bluetooth devices are protected from
radio interference by changing their
frequencies up to a maximum of 1600
times a second
 a technique used known as frequency
hopping.

11. Piconet:
Piconet is the most important
factor in bluetooth connectivity. It is
simply a collection of devices
connected through bluetooth
technology.

12. Piconet(cont)
 While establishing a piconet one unit is act
as master and other as slaves for the
duration of piconet connection.
 The wireless data exchange
standard Bluetooth uses a variety
of protocols. Core protocols are defined by
the trade organization Bluetooth SIG.
Additional protocols have been adopted
from other standards bodies.

13. Advantges of bluetooth:-
 By installing bluetooth in your office
you can do complex tasks of
networking b/w the computing
devices.Each bluetooth device can
connect to 200 other devices.
 It connect all your peripherals
wirelessly.

14. Advantages(cont)
 With bluetooth enabled,we can send
videos,images,voice,document etc
from any communicating device
like(mobile phone,digital camera etc)
 Bluetooth devices are wireless.
 Bluetooth technology is inexpensive.
 Low energy consumption
 Bluetooth is automatic.

15. Disadvantages:-
 Bluetooth devices cannot be
connected with more than one
devices at a time,as it finds problem
in discovering the intended recipients
device.
 Bluetooth has low data rate i.e 1Mbps
in comparison to infra red i.e 4 Mbps.

16. Future of bluetooth:-
 Many of us think that Bluetooth is
going to be here stay,but its wrong.
 Bluetooth will be able to complete all
the other wireless technologies such
as WiFi,networking,infrared data
association etc.
