7.3  What You Should Know About Wireless LAN
Every wireless network must follow these basic guidelines.
• Every wireless client in the same wireless network must use the same SSID.
The SSID is the name of the wireless network. It stands for Service Set IDentity.
• If two wireless networks overlap, they should use different channels.
Like radio stations or television channels, each wireless network uses a specific 
channel, or frequency, to send and receive information.
• Every wireless client in the same wireless network must use security compatible 
with the AP.
Security stops unauthorized devices from using the wireless network. It can also 
protect the information that is sent in the wireless network.
7.3.1  Wireless Security Overview
The following sections introduce different types of wireless security you can set up 
in the wireless network.
7.3.1.1  SSID
Normally, the AP acts like a beacon and regularly broadcasts the SSID in the area. 
You can hide the SSID instead, in which case the AP does not broadcast the SSID.
