What is BLUETOOTH wireless
technology?
BLUETOOTH wireless technology is a short-range
wireless technology that enables wireless data
communication between digital devices, such as a
computer and digital camera. BLUETOOTH wireless
technology operates within a range of about 10 m.
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.
Maximum communication range
Maximum communication range may shorten under
the following conditions.
There is an obstacle such as a person, metal, or
wall between the unit and BLUETOOTH device.
A wireless LAN device is in use near the unit.
A microwave oven is in use near the unit.
