What is Bluetooth wireless technology?
Bluetooth
TM
wireless technology
is a short-range wireless
technology that enables wireless
data communication between
digital devices, such as a
computer or digital camera.
Bluetooth wireless technology
operates within a range of about
10 meters (about 30 feet).
Connecting two devices as
necessary is common, but some
devices can be connected to
multiple devices at the same
time. You do not need to use a
cable for connection, nor is it
necessary for the devices to face
one another, such is the case
with infrared technology. For
example, you can use such a
device in a bag or pocket.
Bluetooth standard is an
international standard
supported by thousands of
companies all over the world,
and employed by various
companies worldwide.
