Bluetooth is the codename of a wireless personal area network specification that is being developed by the Bluetooth SIG (Special Interest Group). Bluetooth will enable electronic devices to spontaneously set up wireless networks within small areas. Bluetooth is designed for notebooks, telephones, and other devices, including wireless headsets, handheld and wearable devices (such as inventory scanners), and data/voice access devices. It also provides peripheral connections for printers, PDAs, desktops, fax machines, keyboards, joysticks, and virtually any other digital device.

The Bluetooth SIG (special interest group) includes hundreds of leading technology companies that are determined to make this specification pervasive. Bluetooth SIG members refer to Bluetooth as third-generation mobile technology. Unlike second-generation devices, such as GSM phones, which are optimized for voice communication, third-generation technology smart phones and communicators are designed for digital content such as speech, pictures, and video. A typical Bluetooth phone will have two radios for example, one for the metropolitan cellular system and one for the Bluetooth personal area network.

This topic continues in "The Encyclopedia of Networking and Telecommunications" with a discussion of the following:

  • Bluetooth specifications (air interface, link ranges, error correction methods, data/voice channels, spread spectrum techniques)
  • Bluetooth joint ventures such as Symbian and WAP (Wireless Applications Protocol)
  • Bluetooth link discovery, establishment, and synchronization methods, including SCO (synchronous connection oriented) and ACL (asynchronous connectionless) links
  • Bluetooth connection scenarios
  • Bluetooth PAN (personal area network) and topologies (scatternets, piconets, masters, slaves, etc.)
  • Bluetooth data exchange
  • Bluetooth security, "domains of trust," and encryption

The topic "Service Advertising and Discovery" discusses methods in which network devices can advertise services they are offering or find out about services being offered on a network. This is important to Bluetooth devices that must dynamically discover the services that are available on networks that the user connects to. The topic discusses several service location models, including Salutation, JetSend (Hewlett-Packard), and Jini (Sun Microsystems).
