Wireless LAN Networking
The following figure provides an example of a wireless network with an AP.
The wireless network is the part in the blue circle. In this wireless network, devices A and B are called
wireless client. The wireless clients use the access point (AP) to interact with other devices (such as
the printer) or with Internet. Every wireless network must follow those basic guidelines.
1. 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.
2. If two wireless network 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.
3. Every device in the same wireless network must use security compatible with the AP or peer
computer.
