It was initially developed by Swedish mobile phone maker Ericsson in 1994 as a way to let laptop computers make calls over a mobile phone. Since then, several thousand companies have signed on to make Bluetooth the low-power short-range wireless standard for a wide range of devices. Industry observers expect Bluetooth to be installed in billions of devices by 2005. The concept behind Bluetooth is to provide a universal short-range wireless capability. Using the 2.4 GHz band, available globally for unlicensed low-power uses, two Bluetooth devices within 10 m of each other can share up to 720 Kbps of capacity. For example, audio devices can include headsets, cordless…show more content…

This makes it an ideal tool for so many electronic devices, as the technology can be implemented pretty much anywhere.One major advantage is its simplicity of use. Anyone can figure out how to set up a connection and sync two devices with ease. Moreover, the technology is completely free to use and requires no charges to be paid to any service provider.The chances of other wireless networks interfering with yours are very low.
