About Bluetooth function
What is Bluetooth technology?
• Bluetooth wireless technology is a short-
range wireless technology that enables
wireless data communication between digital
devices, such as a cellular phone and a
headset. Bluetooth wireless technology
operates within a range of about 10 m (about
33 feet). Connecting two devices 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 since Bluetooth technology is a
wireless technology, neither 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 technology is an international
standard supported by millions of
companies all over the world, and employed
by various companies worldwide.
