The characteristics of Bluetooth

         Bluetooth can achieve data transmission speed of 1Mb / s. Bluetooth supports data transfer speeds up to 720 Kbps in the range of 10 meters. Unlike infrared connection (IrDA), Bluetooth is a scalar and using 2.4 GHz spectrum.

-       power consumption low, allowing applications in a variety of devices, including handheld devices and mobile phones.

-     Low price (the price of a Bluetooth chip is decreasing).

-     distance communication allows:

+ The distance between two terminals can be up to 10 meters and 5 meters outside the building.

+ Gap terminal and the access point can be up to 100m outdoors and 30m indoors.

-     Bluetooth uses the 2.4GHz spectrum range registration ISM band. Speed data transmission can reach a maximum 1Mbps (by using high frequency) that the devices do not need to take each other directly.

Bluetooth History

    Bluetooth name (meaning "blue teeth")  is the name of the king of Denmark - Harald I Bluetooth (Danish Harald Blaatand who unified Sweden and Norway, the Vikings known about the ability to help people be able to communicate and negotiate with each other. The time of the initial era of Bluetooth wireless technology, Bluetooth has a unified meaning the computer industry and telecommunications. Perhaps the researchers have used this to emphasize the design can be exchanged, connect with each other without depending on the type of machine or manufacturer.

 

Bluetooth concept.

Bluetooth is a wireless technology that allows electronic devices, electronic communication with each other in short distances, using radio waves through the general ISM bands (Industrial, Scientific, Medical) in the range floor 2:40 to 2:48 GHz. and capable of transmitting voice and data.

    Scope of operation of Bluetooth devices is 10 meters. Bluetooth data transfer rate of 1 Mbps, 3 and 8 times faster than the average speed of parallel and serial ports respectively . This is the band range no registration is reserved for use with wireless devices in industry, science and health.

     Bluetooth is designed to replace cables purposes between computers and personal communications devices, wireless connections between electronic devices together with a convenient low price.

    When activated Bluetooth can automatically locate other devices that share technology in the area around and start connecting with them. It is oriented to the use of voice and data transmission.
