This chapter has not covered the Bluetooth wireless interface. Investigate the properties of this bus. Indicate where it fits into the world of computer interfaces and its relative merits with respect to wired buses such as USB and wireless busses such as WiFi.

Bluetooth technology is a wireless technology like WiFi. However, it is a very low?power technology and is
intended for very short range links (less than 10 m or 33 feet), particularly between two paired devices such as a
cell phone and earpiece. Low?power Bluetooth devices can operate for months from a small button cell of the
type found in digital watches and heart?rate monitors.
Unlike WiFi, which is an open standard, Bluetooth is a proprietary standard originally created by Ericsson in 1994.
The first stable standard was Bluetooth 1.2, providing a transmission speed of 721 Kb/s, which is well below that
of USB or virtually any other interface (suitable for control, printer, and audio connections). Bluetooth 3.0
appeared in 2009 offering data speeds up to 24 Mb/s, making it comparable to early USB. In 2010 Bluetooth 4.0
emerged supporting three specifications in one (rather like USB 3.0).
