Another form of data transference is Bluetooth , invented in Sweden by Jaap Haartsen and Sven Mattisson who were working with Ericson. it’s a wireless protocol utilizing short-range communication technology. It transfers data over short distances from mobile devices. It was designed to synchronise multiple devices together and overcome any difficulties that came from doing so. It does this by using radio technology called frequency hopping spectrum spread, this cuts up the data into 75 parts that are easier to transfer. Bluetooth is now used in video game consoles, computer printers, digital cameras . The ranges of Bluetooth can be from 1-100 meters and there are a range of wireless products that can be used with Bluetooth. such as hands free head sets, wireless keyboards, printers an video game controllers are installed with Bluetooth. Bluetooth has developed into many different versions these are 1.0,1.1,1.2,2.0 and 2.1 each version has advanced combining new features new features and backwards compatibility. Future plans are being made to enable Bluetooth to become faster and provide information to customers. Because Bluetooth can transfer data quickly and efficiently to devices in a short amount of time over short distances this can be very helpful. I can use this information to design a devise to help find a customers shopping list items.
