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 7-44 on page 7-37

), 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 7-44 on page 7-37

). 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.
