A radio programmed for the WorldWide domain may not be limited to the channels listed in the table above. The
radio can use IEEE 802.11d support or a special Summit-defined mechanism to adapt itself to the channels that
are available on the APs in the vicinity.
802.11d is the ratified IEEE standard for the operation of a wireless LAN client radio in multiple regulatory
domains. Beginning with Version 2.00, Summit software supports a performance-optimized version of IEEE
802.11d. When a Summit radio programmed for the WorldWide domain associates to an AP that is configured for
802.11d, the radio will adapt its channels and maximum transmit power to those for the country specified by the
AP. To take advantage of 802.11d support in Summit software and ensure optimal performance, make sure that
every AP on your WLAN:
Supports 802.11d
Specifies the correct Country information element
Broadcasts its SSID or SSIDs
In addition, make sure that every Summit radio is programmed for a regulatory domain of Worldwide. A radio
that is programmed for a regulatory domain of FCC, ETSI, or TELEC will ignore the Country information
elements from APs.
A Summit radio uses 802.11d only when it tries to associate on an SSID for the first time or after a disconnect.
During the initial association process, if the AP provides a Country information element, then the radio configures
its channel set and maximum transmit power for that country. The radio assumes that all APs with the same SSID
have the same 802.11d country code; as a result, the radio effectively ignores the country code when roaming
from one AP to another.
Beginning with Version 2.01 of Summit software, a Summit radio programmed for the WorldWide domain
supports not only 802.11d but also a "world mode" capability. When the radio is within range of APs that are not
configured for 802.11d, the radio identifies the channels that the APs support and automatically adapts its channel
set to the channels supported by the APs.
