Bluetooth Products, What Are They And How Do They Work?

When it comes to technology, companies are constantly trying to make things "better" quality wise and they are also trying to get us more interested. Bluetooth was named after a tenth-century king, Harald Bluetooth, King of Denmark and Norway.

Bluetooth is an anglicized version of Harald Blaatand, who was known for his unification of previously warring tribes from Denmark (including now Swedish Scania, where the Bluetooth technology was invented) and Norway.

Bluetooth likewise was intended to unify different technologies, such as personal computers and mobile phones. Bluetooth is a wireless communications protocol for exchanging data over close distances from fixed and mobile devices, producing personal area networks (PANs). It was originally conceptualized as a wireless alternative to RS232 data cables. It can connect several devices, overcoming problems of synchronization.

Bluetooth applies a radio technology called frequency-hopping spread spectrum, which hacks up the data being sent and transmits chunks of it on up to 79 frequencies. In its primary mode, the intonation is Gaussian frequency-shift keying (GFSK). It can reach a gross data rate of 1 Mb/s.

Bluetooth provides a way to connect and exchange information between devices such as mobile phones, telephones, laptop computers, personal computers, printing machines, Global Positioning System (GPS) receivers, digital cameras, and video game consoles through a fail-safe, globally unlicensed Industrial, Scientific, and Medical (ISM) 2.4 GHz short-range radio frequency bandwidth.

The Bluetooth specifications are developed and licensed by the Bluetooth Special Interest Group (SIG). The Bluetooth SIG consists of companies in the areas of telecommunication, computing, networking, and consumer electronics. Lets take a look at a few products that use this Bluetooth technology:
