Bluetooth
RADIATION
Issues:Bluetooth is a wireless
TECHNOLOGY
that in
ACTUALLY
FACILITATESCOMMUNICATION
between
DIFFERENT
devices such as cell phones,
COMPUTERS
and
ENTERTAINMENT
SYSTEMS
. Using low-power
RADIO
waves, it is a
CONVENIENT
ALTERNATIVE
to Infrared
COMMUNICATION
such as that used inremote
CONTROLS
. Bluetooth users enjoy
INSTANT
, wireless
COMMUNICATION
.
IMAGINE
having your cell phone
TRANSFER
calls
DIRECTLY
to your home phone
LINE
because Bluetooth
ADVERT
that you were in your home. This
TECHNOLOGY
also allows for
INSTANT
filetransfers and
MESSAGES
between Bluetooth users. ne of the most
SIGNIFICANT
advantages it has over Infrared
TECHNOLOGY
is that the Bluetooth does not need a
LINE
of sight to
TRANSMIT
INFORMATION
. !ow Bluetooth "or#s: Is
RADIATION
a
PROBLEM
$ Bluetooth sends out wea#
RADIO
signals to
CONNECT
up to eight devices to eachother within a range of about %& feet. This is the same
TECHNOLOGY
used by baby
MONITORS
and
PORTABLE
phones. Bluetooth uses a
TECHNIQUE
called 'spread-
SPECTRUM
fre(uency hopping' to ensure that each device is on a
DIFFERENTFREQUENCY
and therefore they do not
INVOLVE
with one another. This gives usersthe
CONVENIENCE
of being able to
CONTROL
a number of
ELECTRONIC
devices inthe home or wor#place from a single Bluetooth-enabled device, such as a cell phone. Because it
EMITS
RADIO
waves, some worry that Bluetooth
RADIATION
could causehealth
PROBLEMS
. )eople
SENSITIVE
to the waves sent out by microwaves, cellphones and
RADIO
towers often complain of
NAUSEA
, headaches and other bothersome
SYMPTONS
ASSOCIATED
with their e*posure. !owever, the Bluetoothsignal at %
MILLIWATT
is e*tremely low,
COMPARED
to some cell phones, which may
EMIT
up to +
WATTS
. The signal is also
TRANSMMITED
throughout a space and not ina single, powerful beam. Bluetooth
RADIATION
is
CONSIDERED
far less bothersomethan cell phone
