What is spread-spectrum technology, and how is it used in wireless transmissions?
Most wireless LANs use spread-spectrum technology: Spread spectrum is a form of wireless communications in which the frequency of the transmitted signal is deliberately varied. This results in a much greater bandwidth than the signal would have if its frequency were not varied. Results also include increases in reliability, integrity, and security. Spread-spectrum transmits a message on ever-changing frequencies that are then reassembled by the receiver. Spread spectrum takes up a lot of bandwidth, but in return the user gains reliability and security for wireless transmissions.
