Settings for the wireless LAN

Network name (SSID)
The Basic Settings Wizard prompts for the access point's network name (fre-
quently referred to as SSID – Service Set Identifier). The name is of your own
choice. Several access points with the same name form a common wireless
LAN.
Open or closed wireless LAN?
Mobile wireless devices select the desired wireless LAN by specifying the net-
work name. Two methods serve to facilitate the specification of network
name:
The wireless LAN can be "closed" in order to prevent this procedure. In this
case it will not accept any devices attempting to register with the network
name 'ANY'.
Selecting a radio channel
The access point operates in a specific radio channel. The radio channel is
selected from a list of up to 13 channels in the 2.4 frequency band or up to 19
channels in the 5 GHz frequency band (individual radio channels are blocked
in some countries. Please refer to the appendix for more details).
The channel and frequency range used determine the operation if the com-
mon wireless standard, with the 5 GHz frequency range corresponding to the
IEEE 802.11a/h standard and the 2.4 GHz frequency range determining ope-
ration in the IEEE 802.11g and IEEE 802.11b standards.
If no other access points are operating within the access point's range, any
radio channel can be set. Otherwise the channels in the 2.4 GHz band must
be selected in such a way that they do not overlap and are as far apart as pos-
sible. In the 5 GHz band the automatic setting, where the LANCOM Access
Point uses TPC and DFS to select the best channel is normally sufficient.

Mobile wireless devices can search ("scan") the vicinity for wireless LANs
and offer the wireless LANs they find in a list for selection.
By using the network name 'ANY' the mobile wireless device registers with
the nearest available wireless LAN.
Please refer to the LCOS reference manual for more information on
TPC and DFS.
