1.2 Bluetooth application

Bluetooth is designed to operate in an environment of many users. Up to eight devices can communicate in a

small network called a piconet. Ten of these piconets can coexist in the same coverage range of the Bluetooth

radio. To provide security, each link is encoded and protected against eavesdropping and interference.

Bluetooth provides support for three general application areas using short-range wireless connectivity:

 Data and voice access points. Bluetooth facilitates real-time voice and data transmissions by providing

effortless wireless connection of portable and stationary communications devices.

 Cable replacement. Bluetooth eliminates the need for numerous, often proprietary cable attachments for

connection of practically any kind of communications device. Connections are instant and are maintained

even when devices are not within line of sight. The range of each radio is approximately 10 m, but can be

extended to 100 m with an optional amplifier.

 Ad hoc networking. A device equipped with a Bluetooth radio can establish instant connection to

another Bluetooth radio as soon as it comes into range.
