This technology provides short-range, wireless connectivity between devices. It is intended to replace the cables connecting portable and/or fixed electronic devices. Cables limit the mobility of the consumer and are easily lost or broken.

A Bluetooth technology is a high speed, low powered wireless technology is used to transmit and receive the data serially. In the embedded system many of electronic project applications, controlling by the Bluetooth technology.


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. This technology eradicates the use of cords, cables, adapters and permits the electronic devices to (or) among each communicate wirelessly other.

Bluetooth is a high-speed, high -speed, low-power microwave wireless link technology, designed to connect phones, laptops, PDAs and other portable equipment eq uipment together with little or no work by the user.


The purpose of Bluetooth technology is rather to enable arbitrary electronic devices to form ad hoc networks.

The Bluetooth technology supports point-to-point and point-to-multipoint connections. A Bluetooth device may be actively connected to up to seven devices simultaneously. Those devices build a socalled piconet. Every piconet contains up to seven slaves and is controlled by a master. Several piconets can be linked together to form a Scatternet.

Bluetooth was invented in 1994 by Ericsson. The company later started working with a larger group of companies called the Bluetooth Special Interests Group, or "SIG," to develop the technology into what it is today. Bluetooth is not owned by any one company and is developed and maintained by SIG. The name Bluetooth came from a code name originally used by SIG for the project and is a reference to a 10th century Danish king named Harold Bluetooth, who was responsible for uniting Norway, Sweden, and Denmark.


 What is Bluetooth Technology: It comprises of a base band processor, a radio and an antenna . The base-band processor converts the data into signals, the antenna of another blue tooth device, within at least 30 feet distance, receives a transmitted signal in the air. It uses a frequency hopping spread spectrum technique (FHSS)) - which is one of two (FHSS basic modulation techniques used in spread spectrum signal transmission. transmiss ion. Frequencies are switched repeatedly during radio transmission to help reduce unlawful access or other means of telecommunication telecommunicationss to cross paths and cause interruption

These have Replaced cables for transferring Information from one Electronic Device to another one. These have decreased Strain like carrying phones while talking, making hands free to do another work. This is cheaply Available. It’s Mobility is also very Important as it doesn’t need any power outlet or Internet connection or any other items.

Disadvantages Of Bluetooth: 

Data sent between two Bluetooth devices is very slow compared with Wi-Fi transfer Rate. Range Of a Bluetooth Device is i s 15-30 feet depending upon the Device. Security is Biggest Disadvantage as transfer takes place through radio waves and a hacker can easily hack it. Battery usage is also a problem, it will make device out of power before it would have if Bluetooth was not powered on.


The Internet Bridge An extension of this model could be a mobile computer that allows surfing the Internet irrespectiveofofwhether the location of the user, and regardless the user is cordlessly connected through a mobile phone (cellular) or through a wire line connection (e.g. PSTN, ISDN, LAN, xDSL).

Automatic Check-in Hotels are testing, or plan to test, services that allow guests to check in, unlock room doors and even control room temperature with handheld

devices equipped with Bluetooth Technology


Smart Home

Homes equipped with Bluetooth devices may be able to recognise the arrival of its bonafide residents and unlock the door on their arrival. The device will also adjust heat to preset temperature. While this is happening, the data from the individual’s PDA maycalendar be exchanged with the homethe electronic board, and the family is updated to reflect scheduled activities in the office. 

It separates the frequency band into hops. This spread spectrum is used to hop from one channel to another, which adds a strong layer of security. securit y. Up to eight devices can be networked in a piconet. Signals can be transmitted through walls and briefcases, thus eliminating the need for line-ofsight. Devices do not need to be pointed at each other, as signals are omni-directional. Governments worldwide regulate it, so it is possible to utilize the same standard wherever one travels


Bluetooth has a good future ahead because it meets a basic need of connectivity. Currently a protocol is being researched that would support large ad hoc networks. Latest version of Bluetooth are improving both its security and capabilities. Ultra wide band has been chosen by the Bluetooth Special Interest Group as the future of Bluetooth Technology. New versions of Bluetooth technology will meet the high-speed and large range. Many companies are designing impressive bluetooth applications in demand.


Authentication and encryption is provided at the Link Manager layer.

The PIN into a 128isbit translated link key which is used for authentication. After authentication the radios will settle on a suitable length encryption key to be used. Bluetooth relies on PIN codes to establish trusted relationships between devices.


A new global standard for data and voice Eliminates Cables.
