Bluetooth wireless technology
Is a wireless communication link, operating in the unlicensed band at 2.4 GHz using a frequency hopping transceiver. It allows real-time AV and data communications between Bluetooth enabled hosts. The link protocol is based on time slots.
Bluetooth Enabled Device
A device that is capable of short-range wireless communications using the Bluetooth system.
Bluetooth Device Address
A 48 bit unique address used to identify every Bluetooth enabled device.
Connectable device.
An enabled device in range that periodically listens on its page scan physical channel and will respond to a page on that channel.
Discoverable Device
A device in range that periodically listens on an inquiry scan physical channel and will respond to an inquiry on that channel. Discoverable device are normally also connectable.
Encryption
Method of encoding data to prevent others from being able to interpret the information.
Object Exchange (OBEX) Protocol
OBEX is a transfer protocol that defines data objects and a communication protocol two devices can use to exchange those objects. OBEX enables applications to work over the Bluetooth protocol stack as well as the IrDA stack. For Bluetooth enabled devices, only connection-oriented OBEX is supported. Three application profiles have been developed using OBEX which include SYNC, FTP and OPP.

Page
The initial phase of the connection procedure where a device transmits a train of page messages until a response is received from the target device or a timeout occurs.
Page Scan
A procedure where a device listens for page messages received on its page scan physical channel.
Paging Device
An enabled device that is carrying out the page procedure.
Paired Device
A Bluetooth enabled device with which a link key has been exchanged (either before connection establishment was requested or during connecting phase).
Personal Area Networking Profile (PAN)
PAN describes how two or more Bluetooth enabled devices can form an ad-hoc network and how the same mechanism can be used to access a remote network through a network access point. The profile roles include the network access point, group ad-hoc network and personal area network user.
WAP Over Bluetooth Profile (WoB)
WAP defines how the wireless application protocol suite can run over a Bluetooth wireless link. A typical configuration is a mobile phone connecting to a public kiosk over a Bluetooth wireless link and using WAP to browse for information. WAP works across a variety of WAN technologies bringing the Internet to mobile devices. For more information on Bluetooth technologies visit www.en.wikipedia.org/wiki/Bluetooth |
