Read About Bluetooth
Bluetooth systems create a personal-area network
(PAN), that may fill a room or may encompass no
more distance than that between the cell phone on a
belt-clip and the headset on your head.
When Bluetooth-capable devices come within range of one another, an electronic conversation
automatically takes place to determine whether they have data to share or whether one needs to control
the other. The devices form a network.
Once this network is established, the devices randomly hop frequencies in unison so they stay in touch
with one another and avoid other networks that may be operating in the same room.
One of the ways Bluetooth devices avoid interfering with other systems is by sending out very weak
signals of 1 milliwatt. By comparison, the most powerful cell phones can transmit a signal of 3 watts.
The low power limits the range of a Bluetooth device to about 10 meters, cutting the chances of
interference between your computer system and your portable telephone or television. Even with the
low power, the walls in your house won't stop a Bluetooth signal, making the standard useful for
controlling several devices in different rooms.
