                                                            Bluetooth

      



         Bluetooth is short radio waves that were developed by a group of electronics companies to allow any two devices - computers, cell phones, keyboards and many devices to carry out the process of contact alone without wires or cables or any intervention by the user. The system enables Bluetooth devices located within coverage waves to communicate with each other, so you can connect two devices located in different rooms, but Bluetooth should have a strong signal to cover this area.



          Bluetooth was developed in 1994 by Sven Mattisson and Haartsen Yap, who were working for Ericsson platforms in Lund, Sweden. Since 1980, companies try to make a new method based on the wireless connection. All these attempts were facing many difficulties are summarized in the additional consumption of electricity, and they face another problem because devices disturb each other.  The biggest problem is that there is no standard basis to work on it. In the meantime, it was believed that  infrared technology is the best solution for communication and wireless connectivity. To achieve this, the 30 companies and there founders, almost in the month of August of 1993 including HP, IBM, try to work together to establish a so-called IrDA Infrared Data Association.  This new technology was struggled with a difficult problem which need for optical communication between different devices as a prerequisite for the completion of the binding process.  Then, they joined with Ericsson Company to find a way to link wireless replaced with wired connectivity. As a result of the research of all companies (Ericsson, Nokia, IBM, Toshiba, and Intel) try to formulate a set of specifications agreed upon, and which is also derived from the knowledge and information from the IrDA. At the end they found the now invention which named Bluetooth.

      

        They developed Bluetooth because they need to solve some problems they faced by connecting some devises, before if they need to send files form computer to other computer they connect the computers by wires  sometimes the devises are far from each other so they need to invent a new thing to send files by wireless. Some digital devices like audio device need two connected with to wires and sometimes need 8 wires or 25 wires, so wireless connection will be easier.



       Bluetooth future looks strong, many companies trying to make Bluetooth reach far away to other device. Also cars companies trying to use Bluetooth in cars, so you can start the engine without switch. Sometimes when you send a file from device to other device, if the size of file is very big it’s taking a long time to reach, so the companies now working to solve this problem. As Hans Vestberg said in his interview “Bluetooth is future of wireless connection“(Hans Vestberg, President Ericsson and CEO).



      In conclusion I think Bluetooth is very important in our life, its make connection with devices very easy. I use Bluetooth to send music or picture form my lap to my mobile phone or from my friend phone to my phone. In future maybe everything will start working with Bluetooth.
