History

The Bluetooth Special Interest Group(SIG) was founded by Ericsson, IBM,Intel, Nokia and Toshiba in February1998 to develop as open specification for short-range wireless connectivity .

W hat Is Bluetooth?

Designed to be used to connect both mobile devicesand peripherals that currently require a wire

Short range wireless radio technology- operate range of 10 meters

Simplifying communications between:- devices and the internet- data synchronization

USB without wires

W hat is Bluetooth?

Bluetooth wireless technology is an openspecification for a low-cost , low-power ,short-range radio technology for ad-hoc

wireless communication of voice and dataanywhere in the world.

Bluetooth Application Programming, p.3

Technical meaning :--

Technically, is a chipto be plugged into computers, printers,mobile phones, etc. Designed by taking

the information normally carried by thecable, and transmitting it at a specialfrequency to a receiver Blue tooth chip

which will then give informationreceived to these mobile devices.

Ma in Str e ngth :

Ability to simultaneously handle both data and voice transmissions suchas headset for voice calls.

Bluetooth Vision

Originally conceived as a cable replacementtechnologyOther usage models began to develop: Personal Area Network (PAN) Ad-hoc networks Data/voice access points

W ireless telematics


12/27


Advantages (+)

W ireless (No Cables)

Low Power Consumption (1 Milliwat)

Industry W ide Support


13/27


Disadvantages (-)

Short range (10 meters)

Small throughput rates- Data Rate 1.0 Mbps

Mostly for personal use (PANs)


14/27


Bluetooth Components

Four major components:

Radio Unit (radio transceiver)

Baseband Unit (flash memory& CPU)

Software Stack (driver software)

Application Software (user interface)

How Does It W ork?

Bluetooth is a standardfor tiny, radio frequencychips that can be pluggedinto your devices

These chips were designed totake all of the information thatyour wires normally send, and

transmit it at a specialfrequency to something

called a receiver Bluetooth chip.


16/27


Bluetooth Frequency

Has been set aside by the ISM for exclusive use of Bluetooth wireless products

Communicates on the 2.45 GHz frequency


17/27


Avoiding Interference : HoppingBluetooth uses a technique called spread-spectrum

frequency hopping.

In this technique, a device will use 79 individual,randomly chosen frequencies within a designated range

Transmitters change frequency 1600 times a second

Bluetooth Specifications

Each channel is divided into time slots 625microseconds long

Data in a packet can be up to 2,745 bits in length

Packets can be up to five time slots wide

File Transfer

Basic transferring of files betweencomputersFile type does not matter

Human interference does not degradetransfer ratesMovement between Bluetooth units does

alter transfer rates
