Bluetooth Technology

Bluetooth technology is a popular wireless technology. It is a networking method that broadcasts data by use of radio waves that are low powered. Bluetooth uses a universally frequency regulated between 2.402 and 2.480 gigahertz.

This frequency range is exclusively identified for the operation of industrial (ISM), scientific and medical devices through an internationally consented agreement.

The specifications were initially developed by Sven Mattisson and Jaap Haartsen in 1994 who were then working in Ericsson Mobile Platforms organization – Lund in Sweden. They are now licensed and developed by SIG – Bluetooth Special Interest Group. The SIG encompasses companies that deal with computing, consumer electronics, networking and telecommunication.

The various devices that use this technology’s radio band are cordless phones, baby monitors, computer printers, entertainment systems and garage-door openers.

The Bluetooth technology specification is founded on the frequency-hoping spectrum spread technology and can be seen as a society of electronic guidelines and procedures that one can use in equipment such as telephones, computers or entertainment systems. The different parts and pieces that include hardware and software create a Bluetooth enabled environment that makes easy the communication of these devices to each other.

This technology is completed without using plugs, wires or cables. To effectively connect equipment using Bluetooth technology, the devises have to be within a region of 30 foot. The information transferable through this technology include media content like songs and movies, data and images.

This simple technology is constantly being streamlined. Since the know-how is both automatic and wireless, the attributes connected to this technology are interesting and can be further manipulated to simplify daily life operations to a large extent. Hence, the interconnectivity skill is more and more becoming complex, day by day.

The Bluetooth 1.0 and 1.0B were the initial versions to be publicly used. The 1.1 followed the 1.0 and it amended many errors being experienced by the earlier version. After the 1.1, came the 1.2 version that had faster connectivity and high transmission speeds. The 2.0 is the current version that was released in November, 2004.

The simplicity and range of operation of this technology is often times questioned. Such uncertainties as the amount of transferable data that the technology can handle at a time, the way in which enabled devises and equipment ‘talk’ to each other and the confirmation that the entire message transferred was received as intact as it was sent are addressed in the formatting of protocols. Protocols are commands and rules that are followed by all Bluetooth enabled devises. The protocols make it easy for different equipment to communicate and transfer data.

A prevalent list of Bluetooth application includes communication between and control of a hands free headset and a mobile cell phone, wireless communication between Personal Computers (PC’s) within a confined area that needs little bandwidth, communication wirelessly between the various peripherals of a PC like printers, mouse and keyboard within a confined space, transfer of data and files between equipment that are OPEX (exchange of binary objects between devices) enabled and replacing wired communications in medical equipment, traffic control equipment and GPS receivers.
