The following figure provides an example of a wireless network.
Figure 26 Example of a Wireless Network
In this wireless network, devices A and B are called wireless clients. The wireless clients use
the access point (AP) which is connected to a WLAN controller to interact with other devices
(such as the printer) or with the Internet. Your NXC-8160 is the WLAN controller.
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.
