6 - 8 MC3000 Integrator Guide Table 6-5 Operating Mode Fields Field Description Operating Mode Infrastructure: Select Infrastructure to enable the mobile computer to transmit and receive data with an AP. Infrastructure is the mobile computer default mode. Ad Hoc: Select Ad Hoc to enable the mobile computer to form its own local network where mobile computers communicate peer-to-peer without APs using a shared ESSID. Country Country: is used to determine 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 to be used in a single country, set every profile country to Allow Any Country. In the Options > Regulatory dialog box (see Figure 6-46 on page 6-38), set the country to the specific country the device is to be used in, and deselect (uncheck) the Enable 802.11d option. This is the most common and the efficient configuration. It eliminates the initialization overhead associated with acquiring a country via 802.11d. Multiple Country Use: When the device may be used in more than one country, select (check) the Enable 802.11d option in the Regulatory Options dialog box (see Figure 6-46 on page 6-38). This eliminates the need for reprograming the country (in Options > Regulatory) each time a new country is entered. However, this only works if the infrastructure (i.e. APs) support 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. 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 6-9 for instruction on setting up authentication.
