The Story of Bluetooth

Wireless bluetooth technology was developed in 1994 by engineers at Ericsson in Sweden. Eventually, a small grouping of vendors such as Ericsson, IBM, Intel, Toshiba, and Nokia created the Bluetooth Special Interest Group(SIG) in order to formalize the technology and make it an industry standard.

Bluetooth relies on a frequency-hopping spread spectrum radio technology to relay wirelessly between a master gadget and as many as seven slave products. This means that your main device, whether it be a smart phone, a laptop computer, or and mp3 player, can have as many as seven distinct Bluetooth devices connected with it concurrently. Although it could possibly appear that all devices are doing the job at the same time, the actual master device essentially talks to each slave product in fast sequence. It occurs so rapidly you won't ever notice, even while playing tunes on Wireless bluetooth earbuds.

Bluetooth is a short-range wireless communication technology. Systems have an average range of about thirty ft. Of course, the farther apart you are, the less condition the transmission will have. It's usually no huge worry simply because Bluetooth devices are intended to operate in closeness to the master unit. A few examples of this include a wireless mouse and keyboard for your computer system, as well as wireless stereo speakers for your home music system.

Since Bluetooth technology also has such a short range, it consumes hardly any power. This is very important, because so many Bluetooth products are small and do not have room for big batteries. This allows you to use your device for extended durations before you must replace batteries or recharge.

There have been 3 major variations of Bluetooth, all versions are backwards compatible with previous variations.

Bluetooth v1: Bluetooth experienced a uncertain start. It didn't have essential security, was slow-moving, as well as was more prone to interference. Throughout up coming updates v1.1 in addition to v1.2, many of those early bugs were resolved.

Bluetooth v2: Released in '04, the primary difference in this variation was speedier information transfer without impacting energy consumption. In version v2.1 secure simple sharing was initially released which improved the pairing experience while strengthening safety measures.

Bluetooth v3: Adopted by the SIG during 2009, Bluetooth 3.0 data transfer rate as much as 24 Mbit/s, eight times greater in comparison with version 2. This is accomplished simply by mixing the Bluetooth together with 802.11 Wireless technology. Look for Bluetooth equipment featuring a +HS on the box, that means these devices supports this cutting edge high-speed technology.

Look for more related to Bluetooth on Wikipedia as well as the official Bluetooth web site. With Bluetooth remaining versatile, standardised, and utilizing small energy, it is the prefect technology for short range wireless technology.

There are many devices that use this technology including Bluetooth earbuds, speakers, and computer peripherals. You can read more about the former at Bluetooth earbuds online.
