WHAT IS BLUETOOTH?

• Bluetooth is a wireless technology used to transfer data between different electronic devices.

• The distance of data transmission is small in comparison to other modes of wireless communication.

BLUETOOTH FOUNDER

• The Bluetooth Specification was developed as a cable replacement in 1994 by Jaap Haartsen and Sven Mattisson, who were working for Ericsson in Lund, Sweden.

• The company that developed the idea was a development branch of LM Ericsson (now merged with Sony to become SonyEricsson).

• They developed the idea in the early 90's, and contacted a number of companies in 1995.

5

VERSIONS OF BLUETOOTH

• Bluetooth version 1.1 or 1.2, which offers such basic features as voice dialing, call mute, and last-number redial.

• Bluetooth 2.0 brought higher connection speeds (as much as three times faster, in some cases), improved performance, and less power consumption.

• Most recent is the new Bluetooth 4.0 spec which major feature is Bluetooth Low Energy, essentially strong power management skills.

FEATURES OF BLUETOOTH

• The key features of Bluetooth technology:• Less complication• Less power consumption• Available at cheaper rates• Robustness

8

APPLICATIONS OF BLUETOOTH

• 1. Wireless networking between mobiles and laptops.

9

APPLICATIONS OF BLUETOOTH

• 2. Peripherals such as mouse, keyboards, and printers.

10

APPLICATIONS OF BLUETOOTH

• 3. Cell phones with Bluetooth technology have been sold in large numbers.

• The standard also includes the support for more powerful and longer range devices.

11

APPLICATIONS OF BLUETOOTH

• 4. The transfer of files, images and MP3, between mobile phones.

• 5. Certain MP3 players and digital cameras to transfer files to and from computers.

12

APPLICATIONS OF BLUETOOTH

• 6. Bluetooth technology headsets for smart phones and cell phones.

13

APPLICATIONS OF BLUETOOTH

• 7. Data logging equipment that transmits data to a computer via Bluetooth technology.

14

ADVANTAGES OF BLUETOOTH

• Bluetooth does not require a clear line of sight between the synced devices.

• This means that the devices need not be facing each other.

• And it is also possible to carry out transfers when both the devices are in separate rooms.

• The fact that this technology requires no cables and wires is something that has made it so popular.

15

ADVANTAGES OF BLUETOOTH

• The maximum range that it offers is 100 meters, but this range is not the same for all similar connections.

• It depends on the nature of the devices and the version that they operate upon.

• One major advantage is its simplicity of use.• Anyone can figure out how to set up a connection

and sync two devices with ease. Moreover.• The technology is completely free to use and

requires no charges to be paid to any service provider.

16

DISADVANTAGES OF BLUETOOTH

• Though the transfer speeds are impressive at around 1 Mbps, certain other technologies like Infrared can offer speeds up to 4 Mbps.

• This is an area that can be improved on in the near future.
