Table 7-5 Operating Mode Fields
Field Description
Operating Mode Select Infrastructure to enable the EDA to transmit and receive data with an AP.
Infrastructure is the default mode.
Select
Ad Hoc to enable the EDA to form its own local network where mobile computers
communicate peer-to-peer without APs using a shared ESSID.
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 7-46 on page 7-34 ), 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 7-46 on page 7-34 ). This eliminates the need
for reprograming 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.
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.
