Navigation & communication
“Bluetooth” is the term used to describe an open standard for wireless speech and data communication over short distances (up to 10 metres) between electronic devices such as mobile phones, computers, or digital cameras.
Using Bluetooth wireless technology introduced in 1999, these appliances can communicate with each other, access shared data, or synchronise data – all without cables. Appliances with Bluetooth capability transmit in the 2.4 GHz frequency range, which is free of licensing and registration requirements. Bluetooth does not require a line of sight between the appliances, and transmission functions even through walls, which is a clear advantage over infrared. For data security, Bluetooth technology uses 64–128 bit encryption. In addition, a PIN code entered when a connection is initiated provides protection from unwanted listeners.
The name “Bluetooth” comes from the Viking king Harald Bluetooth, who united the Vikings of Denmark and Norway in the tenth century AD. In the same way, Bluetooth technology today unites e.g. your mobile telephone with your BMW Motorrad helmet with integrated Bluetooth communication system. Telephone conversations or conversations between rider and pillion passenger are now possible without cumbersome cable connections.
A further advantage of Bluetooth technology lies in the low transmission power of the appliances. According to the current status of scientific research, Bluetooth technology does not have any negative effects on health.
