 This technology provide short -range ,wireless
connectivity between device .
 It is intended to replace the cables connecting portable
and/or fixed electronic devices.
 Cables limit the mobility of the consumer and are easily
lost or broken.
Bluetooth is a high-
speed, low-power
microwave wireless
link technology,
designed to connect
phone, laptop, PDAs
and other portable
equipment together
with little or no work
by the user.
It comprises of a base band processor, a radio and an
antenna. The based-band processor converts the data into
signal, the antenna of another Bluetooth device, within at
least 30 feet distance, receives a transmitted signal in the
air.
It uses a frequency hopping spread spectrum technique
(FHSS) - which is one of two basic modulation technique
used in spread spectrum signal transmission. Frequencies
are switched repeatedly during radio transmission to help
reduce unlawful access or other means of
telecommunications to cross paths and cause
interruption.
Headset
In-car Bluetooth System
Bluetooth Equipped Printer
Bluetooth Equipped Web Cam
Bluetooth GPS System
Bluetooth Keyboard
 These have replaced cables for transferring information
from one electronic devices to another one.
 These have decreased strain like carrying phones while
talking, making hands free to do another work.
 This is cheaply available.
 Its mobility is also very important as it doesn't need any
power outlet or internet connection or any other items.
Advantages
 Eliminates wires
 Facilitates data and voice
communication
 Offers formation of Ad hoc
networks
 Standardized protocol
 Free to charge
 Easy to use
Disadvantages
 Data sent between two
Bluetooth devices is very
slow compared with Wi-Fi
transfer rate.
 Range of a Bluetooth device
is15-30 feed depending upon
the device.
 Security is biggest
disadvantage as transfer
takes place through radio
waves and a hacker can
easily hack it.
 The internet bridge.
 An extension of this modal
could be mobile computer
that allows surfing the
internet irrespective of the
location of the user, and
regardless of whether the
user is cordlessly connected
through a cell phone
(cellular) or through a wire
line connection ( e.g.,
PSTN, ISDN, LAN, xDSL).
 Automatic check-in
 Hotels are testing or plan to
test , services that allow
guests to check in, unlock
room doors and even control
room temperature with
handheld devices equipped
with Bluetooth technology.
 Bluetooth has a good future ahead because it meets a basic need of
connectivity.
 Currently a protocol is being researched that would support large
ad hoc networks.
 Latest version of Bluetooth are improving both its security and
capabilities.
 Ultra wide band has been chosen by the bluetooth special interest
group as the future of bluetooth.
 New versions of Bluetooth technology will meet the high-speed and
large.
 Many companies are designing impressive
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 improvement are planned to be made in:-
• Data Rates
• Power Reduction
• Range.
