Description
Enabling support for IEEE 802.11d on the access point causes the AP to broadcast which country it
is operating in as a part of its beacons:
• To enable 802.11d regulatory domain support, click Enabled.
• To disable 802.11d regulatory domain support, click Disabled.For the two-radio AP, two
MAC addresses are shown: one for each Radio on the Internal interface.
Note: The IEEE 802.11d defines standard rules for the operation of IEEE 802.11 wire-
less LANs in any country without re-configuration. IEEE 802.11d allows client sta-
tions to operate in any country without re-configuration. The Devicescape
Reference AP must be configured by the Manufacturer via the command line
interface (CLI) country codes for operation in a particular country.
Description
The Administration UI will show whether IEEE 802.11h regulatory domain control is in effect on the AP. IEEE
802.11h cannot be disabled by an end user Administrator. The following details are provided for informational
purposes only.
IEEE 802.11h is a standard that provides two services required to satisfy certain regulatory domains for the
5GHz band. These two services are Transmit Power Control (TPC) and Dynamic Frequency Selection (DFS).
• TPC requires that Radio Local Area Networks (RLANs) operating in the 5 GHz band use trans-
mitter power control. This involves adhering to a regulatory maximum transmit output power and
a mitigation requirement for each permitted channel. The result of which is the reduced interfer-
ence with satellite services.
• DFS requires that RLANs operating in the 5 GHz band implement a mechanism to avoid co-
channel operation with radar systems and ensure uniform utilization of any available channels.
Note: 802.11h is automatically enabled if the AP is configured to work in any country that
requires 802.11h as a minimum standard. This standard is currently only required by those
countries which fall into the European Telecommunications Standard Institute (ETSI) cate-
gory. 802.11h is also enabled for Japan.
