7.9.1 Wireless Network Overview
The following figure provides an example of a wireless network.
Figure 56 Example of a Wireless Network
The wireless network is the part in the blue circle. In this wireless network,
devices A and B use the access point (AP) to interact with the other devices (such
as the printer) or with the Internet. Your P-870HN-51D is the AP.
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.
Security stops unauthorized devices from using the wireless network. It can also
protect the information that is sent in the wireless network.
