The Story of Bluetooth

Wireless bluetooth technology was made in 1994 by technicians at Ericsson in Sweden. Eventually, a group of vendors like Ericsson, IBM, Intel, Toshiba, and Nokia developed the Bluetooth Special Interest Group(SIG) in an effort to formalize the technology and make it an industry standard.

Bluetooth implements a frequency-hopping spread spectrum radio technology to interact wirelessly between a master device and up to seven slave items. This means that your primary component, whether it be a smart phone, a mobile computer, or and iphone, is capable of having up to seven various Bluetooth devices linked to it together. Although it may well seem that all products are working all at once, the master item really talks to each slave system in rapid succession. It occurs so rapidly that you will never detect, even when listening to music on Wireless Bluetooth earbuds.

Bluetooth is a short-range wireless connection technology. Products have an average range of about 30 feet. Naturally, the farther apart you are, the less condition the signal can have. Normally, this is not really a huge worry because wireless earbuds are supposed to work in close proximity to the master device. Examples of this include a wireless mouse and keyboard for use on your computer, or perhaps wireless speakers for your home audio system.

Considering that Bluetooth technology has such a restricted range, it consumes minimal power. This is extremely important, since many Bluetooth devices are small and don't possess space for big batteries. This lets you make use of your product for long amounts of time before you must replace batteries or recharge.

There've been 3 major versions of Bluetooth, all variants are backwards compatible with preceding versions.

Bluetooth v1: Bluetooth previously had a difficult start. It was without essential security, was slow-moving, as well as was vulnerable to interference. Throughout succeeding revisions v1.1 and v1.2, a number of these original bugs have been resolved.

Bluetooth v2: Introduced in the year 2004, the primary difference in this release was swifter information transfer with out having an effect on power usage. In version v2.1 secure simple sharing had been introduced which enhanced the pairing experience whilst fortifying security.

Bluetooth v3: Adopted by the SIG in 2009, Bluetooth 3.0 data transfer rate as much as 24 Mbit/s, eight times faster as compared with version 2. This is achieved by merging the Bluetooth along with 802.11 Wi-fi technology. Look for Bluetooth devices that have a +HS on the container, which means the unit supports this cutting edge high speed technology.
