BLUETOOTH
Short-range wireless
technology
The Bluetooth function might
not be available in certain
countries.
Bluetooth is a short-range
wireless technology. Bluetooth
devices are short-range devices
transmitting on the license-free
ISM band (Industrial, Scientific,
Medical) between 2.402 GHz
and 2.480 GHz. They can
be operated anywhere in the
world without a licence being
required.
Although Bluetooth is designed
to establish and sustain ro-

Set-
distances, as with every other
wireless technology disruptions
are possible. Interference can

and con-
tions can sometimes fail. Par-

operate in a Bluetooth network,
with wireless technology of this
nature it is not possible to en-
sure fault-free communications
in every situation.
Possible sources of
interference:
Pairing
Two Bluetooth devices have
to recognise each other be-
fore they can communicate.
This process of mutual recogni-
tion is known as pairing. When
two devices have paired they
remember each other, so the
pairing process is conducted
only once, on initial contact.
