The technology of Bluetooth wireless is a short range
communications method intended to replace the cables that connect portable or
fixed devices while maintaining the highest levels of security.
The key features offered by
Bluetooth include low power and low cost. The specification in Bluetooth
defines a uniform structure for a wide range of devices to communicate and
connect with one another.
The technology behind Bluetooth
has achieved global satisfaction such as enabled devices, almost everywhere in
the world. Bluetooth devices will connect and communicate without wires
through short range and networks known as piconets.
Each device will simultaneously
communicate with up to seven other devices within a single piconet, meaning
that each device can also belong to several piconets simultaneously. The
piconets are dynamically established as Bluetooth enabled devices enter and
leave the proximity of radio.
A fundamental to Bluetooth
strength is the ability to handle both data and voice transmissions simultaneously.
This will enable users to enjoy varieties of innovative solutions such as hands
free talking, printing and fax capabilities, and other applications.
Specifications Unlike other
standards of wireless, the Bluetooth specification gives product developers
both a link layer and application layer definitions, which will help support
data and voice applications.
Spectrum The Bluetooth
technology operates in the industrial and scientific band at 2.4 to 2.485 GHz,
using a spread spectrum, frequency hopping signal.
Interference The adaptive
frequency hopping of Bluetooth technology was designed to reduce interference between
wireless technologies that share the 2.4 GHz spectrum. Adaptive frequency
hopping (AFH) works well within the spectrum to take full advantage of the
frequency available.
AFH hopping allows for more
efficient transmission within the spectrum, which provides users with greater
performance even if they are using other technologies along with
Bluetooth.
