Bluetooth
Bluetooth is a short-range wireless communications
technology capable of exchanging information over a
distance of about 30 feet without requiring a physical
connection.
Unlike infrared, you don't need to line up the devices to
beam information with Bluetooth. If the devices are
within a range of one another, you can exchange
information between them, even if they are located in
different rooms.
