Appendix D Wireless LANs An ESSID (ESS IDentification) uniquely identifies each ESS. All access points and their associated wireless stations within the same ESS must have the same ESSID in order to communicate. Infrastructure WLAN Channel A channel is the radio frequency(ies) used by IEEE 802.11a/b/g wireless devices. Channels available depend on your geographical area. You may have a choice of channels (for your region) so you should use a different channel than an adjacent AP (access point) to reduce interference. Interference occurs when radio signals from different access points overlap causing interference and degrading performance. Adjacent channels partially overlap however. To avoid interference due to overlap, your AP should be on a channel at least five channels away from a channel that an adjacent AP is using. For example, if your region has 11 channels and an adjacent AP is using channel 1, then you need to select a channel between 6 or 11. 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 144 FSG1100HN User's Guide

An ESSID (ESS IDentification) uniquely identifies each ESS. All access points
and their associated wireless stations within the same ESS must have the
same ESSID in order to communicate.

Channel
A channel is the radio frequency(ies) used by IEEE 802.11a/b/g wireless
devices. Channels available depend on your geographical area. You may
have a choice of channels (for your region) so you should use a different
channel than an adjacent AP (access point) to reduce interference.
Interference occurs when radio signals from different access points overlap
causing interference and degrading performance.
Adjacent channels partially overlap however. To avoid interference due to
overlap, your AP should be on a channel at least five channels away from a
channel that an adjacent AP is using. For example, if your region has 11
channels and an adjacent AP is using channel 1, then you need to select a
channel between 6 or 11.
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
