What is Bluetooth? •^

Bluetooth is a short-range wireless network technologyoperating in the

GHz frequency band originally intended

to replace the cable(s) connecting portable and/or fixedelectronic devices.•^

such a network is also sometimes called a PAN (Personal AreaNetwork).

-^

part of IEEE

WPAN standard.

  • Bluetooth – also the nickname of Harald Blaatand (Jelling,

AD

940

-^981

), King of Denmark and Norway.

-^

The concept was first patented by Ericsson. Currently theBluetooth trade mark is owned by the Bluetooth SIG (SpecialInterest Group), a consortium of companies having stake inBluetooth.

-^

Key features are robustness, low power, and low cost.

Comparison with other wirelesstechnologies^ •

802.11^ •

has higher bit rate compared to Bluetooth but has higher powerconsumption. Basically it is a LAN technology so not a directcompetitor for Bluetooth.

•^

IrDA^ •

low cost but require Line of sight. Only point to point networking.

•^

HomeRF^ •

competing technology but current Bluetooth is better positionedin market.

Logical Channels^ • Five logical channels in Bluetooth to carry different types of

payload traffic:

  • Link control (LC)

•^

used to manage the flow of packets over the link interface.

  • Link manager (LM)

•^

transports link management information between participatingstations.

  • User asynchronous (UA)

•^

carries asynchronous user data.

  • User isochronous (UI)

•^

carries isochronous user data.

  • User synchronous (US)

•^

carries synchronous user data.
