Tap Next . If Ad-Hoc mode was selected the Ad-Hoc dialog box displays. If Infrastructure mode was selected the
Authentication dialog box displays. See Authentication on page 4-8 for instruction on setting up authentication.
Ad-Hoc
Use the Ad-Hoc dialog box to select the required information to control Ad-Hoc mode. This dialog box does not
appear if you selected Infrastructure mode. The channels listed are dependent upon the band selected in the
Options > Band Selection window. See Band Selection on page 4-34 for more information. To select Ad-Hoc mode:
Country Country determines if the profile is valid for the country of operation. The profile country must
match the country in the options page or it must match the acquired country if 802.11d is
enabled.
Single Country Use:
When the device is only used in a single country, set every profile country to
Allow Any Country .
In the Options > Regulatory dialog box (see Figure 4-46 on page 4-34 ), select the specific
country the device is used in, and deselect the Enable 802.11d option. This is the most common
and efficient configuration, eliminating the initialization overhead associated with acquiring a
country via 802.11d.
Multiple Country Use:
When the device is used in more than one country, select the
Enable 802.11d option in the
Options > Regulatory dialog box (see Figure 4-46 on page 4-34 ). This eliminates the need for
reprogramming the country (in Options > Regulatory ) each time you enter a new country.
However, this only works if the infrastructure (i.e., APs) supports 802.11d (some
infrastructures do not support 802.11d, including some Cisco APs). When the Enable 802.11d
option is selected, the
Options > Regulatory > Country setting is not used. For a single profile
that can be used in multiple countries, with infrastructure that supports 802.11d (including
Symbol infrastructure), set the Profile Country to
Allow Any Country . Under Options >
Regulatory , select Enable 802.11d . The Options > Regulatory > Country setting is not used.
Country
(Continued) For a single profile that can be used in multiple countries, but with infrastructure that does not
support 802.11d, set the profile country to
Allow Any Country , and de-select (uncheck) Enable
802.11d . In this case, the Options > Regulatory > Country setting must always be set to the
country the device is currently in. This configuration option is the most efficient and may be
chosen for use with any infrastructure. However, the
Options > Regulatory > Country setting
must be manually changed when a new country is entered.
Note that using a single profile in multiple countries implies that there is a common ESSID to
connect to in each country. This is less likely than having unique ESSIDs in each country, this
requires unique profiles for each country.
For additional efficiency when using multiple profiles that can be used in multiple countries,
the country setting for each profile can be set to a specific country. If the current country (found
via 802.11d or set by
Options > Regulatory > Country when 802.11d is disabled) does not
match the country set in a given profile, then that profile is disabled. This can make profile
roaming occur faster. For example, if two profiles are created and configured for Japan, and
two more profiles are created and configured for USA, then when in Japan only the first two
profiles are active, and when in USA only the last two are active. If they had all been configured
for
Allow Any Country , then all four would always be active, making profile roaming less
efficient.
