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.
