Chapter 8 Interface
Like radio stations or television channels, each wireless network uses a specific channel,
or frequency, to send and receive information.
• Every wireless client in a wireless network must use security compatible with the AP.
Security stops unauthorized devices from using the wireless network and can protect the
information that is sent in the wireless network.
