Be helpful to know the history of the early Bluetooth before membahsnya further . Bluetooth name originated from a prestigious project promoted by
the international giant companies engaged in telecommunications and computers
, including Ericsson , IBM , Intel , Nokia and Toshiba .
With the code name of Bluetooth ,
the project started in 1998 because it was inspired by a Viking King ( Denmark
) were named Herald Blatand . The Herald Blatand ruling king in the 10th
century and controlled most of the Danish and Scandinavian region at that time
. Due to the vast area of his power , the king 's finance Blatand Herald
scientists and engineers to build a metamorphosis tech project that aims to
control the forces of the tribes in the Scandinavian area remotely . Then for
menhormati it , which means that Blatand Bluetooth ( in English ) project is
named .
Released for the first time Bluetooth version 1.0 and 1.0B on July 26, 1999 this product is not perfect , because it has a lot of problems and supporting manufacturing companies have difficulty in applying this technology in their products . For this version , it takes command on the Hardware Device Address manual transmission when the connection between the two devices in a network , so that the user's security is not guaranteed , and the use of anonymous protocols are not possible in this version . So setting too complicated to be done .
Then in October of the same year , Bluetooth has been updated and released version 1.1 and 1.2 . This version has been done for the improvement :
- The use of max in the Hardware Device Address to protect users from identity snooping and tracker .
- The use of anonymous protocols are available , but not implemented , so that ordinary consumers can not use it .
- Adaptive Frequency Hopping ( AFH ) , to improve the durability of radio frequency interference that is used by many people in the hopping sequence .
- The use of high-speed transmission .
With increasing support manufacturing companies such as 3Com , Ericsson , IBM , Intel , Lucent Technologies , Microsoft , Motorola , Nokia and Toshiba , manufacturing formed a group called The Bluetooth SIG ( Special Interest Group ) . The technology then was to make improvements to version 2.0 and arguably the final version . Additional features of the Ericson released not too detailed , but the point is :
- Non - hopping diperkenankannya narrowband channels . Where in this channel can be used for Bluetooth profile services by various devices with a very high volume of Bluetooth devices simultaneously .
- Not dienkripsinya general information in realtime , so basic traffic congestion and speed traffic information to the destination can be avoided when transmitted by the device with the passing of each host with high speed .
- Multiple speeds level .
May be useful .
