Figure 22 Example of a Wireless Network

are called wireless clients. The wireless clients use the access point (AP) to interact with other

Every wireless network must follow these basic guidelines.
• Every device 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 a different channel.
Like radio stations or television channels, each wireless network uses a specific channel,
or frequency, to send and receive information.
• Every device in the same wireless network must use security compatible with the AP or
peer computer.
Security stops unauthorized devices from using the wireless network. It can also protect
the information that is sent in the wireless network.
