6.2 Wireless LAN Basics

Refer also to the Wizard Setup chapter for more background information on Wireless LAN
features, such as channels.

6.2.1 RTS/CTS

A hidden node occurs when two stations are within range of the same access point, but are not
within range of each other. The following figure illustrates a hidden node. Both stations (STA)
are within range of the access point (AP) or wireless gateway, but out-of-range of each other,
so they cannot “hear” each other, that is they do not know if the channel is currently being
used. Therefore, they are considered hidden from each other.
