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.

> 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.

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.

How bluetooth technology work?

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.

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.

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.

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.

Advantages

This device are automatic.

This device are wireless.

low energy consumption.

Bluetooth technology is inexpensive.

Disadvantages

One device at a time.

Data transfer rate is low.

Security threats: * bluejacking. * bluebugging.

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 .
