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.

What 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

What is Bluetooth?

Bluetooth wireless technology is an openspecification for a low-cost, low-power,

short-range radio technology for ad-hoc

wireless communication ofvoice and dataanywherein the world.

Bluetooth Application Programming, p.3


7/26

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 special

frequency to a receiverBluetooth chip

which will then give informationreceived to these mobile devices.


8/26

Main Strength:

Ability to simultaneously handle

both data and voice transmissions such

as headset for voice calls.


9/26

Technical Features

2.4 GHz ISM Open Band

10/26

Key Features:

Robustness, low complexity, low power

and low cost


11/26

Bluetooth Vision

Originally conceived as a cable replacementtechnology

Other usage models began to develop:

Personal Area Network (PAN)Ad-hoc networks

Data/voice access points

Wireless telematics


12/26

Advantages (+)

Wireless (No Cables)

Low Power Consumption (1 Milliwat)

Industry Wide Support


13/26

Disadvantages (-)

Short range (10 meters)

Small throughput rates- Data Rate 1.0 Mbps

Mostly for personal use (PANs)


14/26

Bluetooth Components

Four major components:

Radio Unit (radio transceiver)

Baseband Unit (flash memory

& CPU)

Software Stack (driver

software)

Application Software (user

interface)


15/26

How Does It Work?

Bluetooth is a standardfor tiny, radio frequency

chips that can be plugged

into your devices

These chips were designed to

take all of the information that

your wires normally send, and

transmit it at a specialfrequency to something

called a receiver

Bluetooth chip.


16/26

Bluetooth Frequency

Has been set aside by the ISM for exclusive use of

Bluetooth wireless products

Communicates on the 2.45 GHz frequency


17/26

Avoiding Interference : Hopping

Bluetooth uses a technique called spread-spectrumfrequency hopping.

In this technique, a device will use 79 individual,

randomly chosen frequencies within a designated range

Transmitters change frequency 1600 times a second

22/26

Bluetooth Specifications

Each channel is divided into time slots 625

microseconds long

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

Packets can be up to five time slots wide


23/26

File Transfer

Basic transferring of files betweencomputers

File type does not matter

Human interference does not degradetransfer rates

Movement between Bluetooth units does

alter transfer rates
