Bluetooth is a wireless technology standard that allows short-range exchange of data between various digital devices like mobile phones, laptops, printers, etc. It was developed in 1994 by Ericsson to replace cable connections between devices. Bluetooth works by establishing short-range radio links between devices that are within 10 meters of each other. It has various applications including file transfer, wireless keyboards/mice, connecting devices like headphones, cameras to phones. Advantages are wireless connectivity and low power usage, while disadvantages include slow data rates and potential security issues. Future developments may include combining Bluetooth with 5G for improved performance and connectivity across more devices.

4. What is bluetooth ?
> Bluetooth is a technology standard for
exchanging data over short distances .
> Bluetooth technology eliminates the
need for numerous and inconvenient
cable attachments
> This technology enable users to
automatically & easily connect a wide
range of computing & telecommunication
devices.

5. > Bluetooth makes wireless communication
and networking between devices in a small
localized area.
>In bluetooth all the conections between
devices are occuring immediately and
invisible.
>Bluetooth is actually a standard for
wireless communications between device
with in a range of 10 metres.

6. History
It was taken from the 10th century danish king
harald blatand who unified denmark & norway.
 In 1994 ericsson study on a wireless technology to
link mobile phones accessories.
In 1997 intel agree to collaborate.
5 comanies joined to from the bluetooth the special
interst group (SIG) in 1998.
Bluetooth SIG formed –ericsson
,intel,ibm,nokia,toshiba.
 first specification released in july 1999.

7. Bluetooth is a high-speed ,low-power
microwave wireless link technology, designed to
connect phones,laptops & other portable
equipments together with little or no work by
the user.
Two bluetooth products can exchange their
addresses & capabilities just after coming with
in the range of about 10 metres.

8. The bluettooth modules can be eiter
built into electronic device or used as an
adaptor .for instance in apc they can be
built in as a pc ncard or externally
attached via the USB port
Connection can be point-to-point or
multipoint.the maximum range is 10
meters but can be extended to 100
meters by increasing the power.

9. Application
Wireless communication with PC input and
output devices, the most common being
the mouse, keyboard and printer.
>Transfer of files, contact details, calendar
appointments, and reminders between devices
with OBEX.
Replacement of previous wired RS-232 serial
communications in test equipment, GPS
receivers, medical equipment, bar code
scanners, and traffic control devices.

10. Short range transmission of health sensor
data from medical devices to mobile
phone, set-top box or
dedicated telehealthdevices.
> Personal security application on mobile phones
for prevention of theft or loss of items. The
protected item has a Bluetooth marker (e.g. a
tag) that is in constant communication with the
phone. If the connection is broken (the marker
is out of range of the phone) then an alarm is
raised. This can also be used as a man
overboard alarm. A product using this
technology has been available since 2009.

12. Advantages
 This device are automatic.
 This device are wireless.
 low energy consumption.
Bluetooth technology is
inexpensive.

13. Disadvantages
 One device at a time.
 Data transfer rate is low.
 Security threats:
* bluejacking.
* bluebugging.

14. Future of bluetooth
technology.
It meets a basic need of connectivity in closed .
proximity hence high demand expected to grow .
 Adoption of smart phones and hand held device
,bluetooth will have tremendous effect on every day
life.
Combining with other technologies e.g. 4G, 5G .

15. Conclusion
A new global Standard for data and voice
Eliminate Caables
Low Power ,Low Range Low Cost network
devices
Deliveries Automatic synchronicity between
devices
Future Improvement
•
Master Sleve relationship can be adjusted
dynamically optimal resourses allocation and
utilization
•
Adaptive ,Lcosed loop transmit power controll
can be implemented further reduce unnecessary
power usage
