Introduction
What is BLUETOOTH
technology?
BLUETOOTH wireless technology is a
short-range wireless technology that
enables wireless data communication
between digital devices, such as a mobile
(cellular) phone and a headset.
BLUETOOTH wireless technology
operates within a range of about 10 m (30
ft). 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.
