Introduction To Bluetooth
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.
