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.
