8.2 What You Need to Know
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.
