Operating Mode Fields
Field Description
Operating Mode Select Infrastructure to enable the vehicle computer to transmit and receive data with an
AP. Infrastructure is the default mode.
Select Ad Hoc to enable the vehicle computer 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 4-44 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 4-44 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.
