Radio Frequency
• Band : if desired, specifies the band on which the SSID to which the oMG is
connecting will be found. By default, the oMG will search all bands until it
finds the AP.
• Channels : if desired, specifies the channel (frequency) on which the SSID to
which the oMG is connecting will be found. By default, the oMG will search all
the channels in the chosen band(s).
A.6 LAN Settings
A.6.1 Access Point Settings
• Network Type : the version of the 802.11 protocol to be used by this access
point (either 802.11b/g or 802.11n). Note that not all WiFi cards support
802.11n. This will default to 802.11n if the card supports it, or will go to
802.11b/g otherwise.
• Auto SSID : if enabled, the oMG will generate the SSID (Service Set
Identifier) for the WLAN. This will be the ESN of the oMG for the primary
BSSID (Basic Service Set Identifier) and the ESN followed by an underscore
and a digit (i.e. ESN_2) for virtual BSSIDs (see below).
• SSID : if Auto SSID is not enabled, the string in this field will be used as the
SSID. The default value is the same as the value that would result from
enabling Auto SSID.
• Channel : the WiFi channel/frequency (i.e. centre frequency) within the
spectrum to be used. This should be chosen with consideration given to other
devices which may interfere with the channel (including other WiFi devices
within the oMG).
• Secondary Channel : a channel which is combined with the primary channel
to provide a 40 MHz channel instead of a 20 MHz channel. The available
options depend on the primary channel. For some primary channels, the
secondary channel can only be below the primary; for others, it can only be
above; for others it can be either. If set, the secondary channel's position will
be relative to (i.e. below or above) the primary channel in the spectrum.
