Bluetooth was designed to allow low bandwidth wireless

connections to become easy to use so even those who

are new to wireless can use them. Version 1.1 of

Bluetooth describes a low power, short range wireless

networking technology that uses radio waves to send

data at rates up to 720 kilobits a second.

The specification for Bluetooth provides for different

classes of radio that allow transmission ranges of

up to 100 meters by boosting the radio power. The

technology of Bluetooth isn't limited to line of

sight transmission since it uses directional waves

that are capable of transmitting through many

obstructions.

Bluetooth is an industry standard communication of

wireless, meaning that it enables the connection

of other devices as well, such as cell phones,

computers, digital cameras, and other types of

electronic devices. The specification of Bluetooth

defines a radio system and a "stack" of protocol

layers and profiles. The highest layer is the

application layer, while the lowest layer is the

radio.

The wireless technology of Bluetooth is positioned

to revolutionize the personal connectivity market

by providing freedom from inconvenient fixed type

lines.

The specification for Bluetooth eliminates the need

for cables by providing a small form factor, low

cost wireless solution that will link computers,

cell phones, and other electronics. Bluetooth

also allows users to connect many ranges of devices

quickly and easily and expands communications

capabilities as well.

The size of the Bluetooth radio is amazing, as a

Bluetooth radio can be built into one or two very

small microchips then integrated into any electronic

device where wireless operations would be an

advantage.

Bluetooth also offers a robust link, which ensures

that normal operating circumstances are not

interrupted by interference from other signals

that are operating in the same frequency band.

Also known for its worldwide operation, Bluetooth

radio operates in the 2.4 GHz frequency band, which

is license free and available to any type of

radio system in the world. No matter where you

are in the world, you count on Bluetooth to work.

Security is also important. Offering advanced

security mechanisms, Bluetooth ensures a high level

of security. Therefore, authentification will

prevent unauthorized acess to important data and

make it very difficult to listen in.

Bluetooth also boasts power optimization. The radio

is power friendly and the software for Bluetooth

is very configurable, limiting the power consumption

of equipment. The radio itself only consumes a

small amount of power from a cellular phone.
