With the applications and architecture as a starting point, we can then spend the next several months on some of the finer details of the various mechanisms included in the Bluetooth protocol and interface stack. In a nutshell, Bluetooth can provide users with the ability to easily interact with a wide range of network applications that include voice and data applications. The equipment used to access the network can include PDAs, voice headsets, and cellular phones. To be viable, applications built on the Bluetooth interface must be easy to use and must operate efficiently. Furthermore, as a wireless application that can be used in public spaces, some degree of security must be provided.
Users are likely to be sharing some form of private information over the links.
When in reasonable proximity of network services, user equipment should require no more than a minimum essential set of user actions to activate the applications. The system must automatically detect all available devices, discover available services, and make it as easy as possible for the end users to access the services that they are seeking. The types of information exchanged over the Bluetooth interface can include a broad range of voice and data applications. If you think for a moment about the types of applications that are handled in a home, an office, or in the domain of mobility, almost all are included in the set of Bluetooth applications. The SIG has identified several applications that are used as reference applications.
