Enable H Band Support
In compliance with FCC regulations, Dynamic Frequency Selection is required in the middle frequency band (M band:
5.25 GHz - 5.25 Ghz) and high frequency band (H band: 5.470 GHz - 5.725 GHz). DFS is enabled automatically when
you use one or both of these frequency bands.
If the AP’s Wireless Card A is variant 2, 3, or 6, the M band channels are enabled by default, and DFS is performed
automatically and cannot be disabled. To add H band channels to the list of available channels, select Enable H Band
Support on the Op Mode page. When the H band is enabled, DFS is enabled automatically, and is performed on both M
and H band channels.
If the AP’s Wireless Card A is variant 8, 10, or 11, both M and H band channels are enabled automatically. DFS is
performed on both M and H band channels and cannot be disabled.
To identify your AP’s software variant, click Monitor > Version to view the Version tab.
For a full discussion of Dynamic Frequency Selection, see Dynamic Frequency Selection/Radar Detection (DFS/RD).
Super Mode and Turbo Mode
Super mode improves throughput between the access point and wireless clients that support this capability. For wireless
clients that support this capability the AP will negotiate and treat them accordingly, for other clients that do not support
super mode, the AP will treat them as normal wireless clients.
Super mode can be configured only when the wireless operational mode is one of the following:
• 802.11a only mode
• 802.11g only mode
• 802.11b/g mode
NOTE: Super mode is not available in 802.11b and 802.11g-wifi operational modes.
Super mode is supported in the 2.4 GHz and 5 GHz frequency bands in all regulatory domains.
Turbo mode is not supported on the Mesh and Access Point Module. This option will be greyed out.
IEEE 802.11d Support for Additional Regulatory Domains
The IEEE 802.11d specification allows conforming equipment to operate in more than one regulatory domain over time.
IEEE 802.11d support allows the AP to broadcast its radio’s regulatory domain information in its beacon and probe
responses to clients. This allows clients to passively learn what country they are in and only transmit in the allowable
spectrum. When a client enters a regulatory domain, it passively scans to learn at least one valid channel, i.e., a channel
upon which it detects IEEE Standard 802.11 frames.
The beacon frame contains information on the country code, the maximum allowable transmit power, and the channels to
be used for the regulatory domain.
The same information is transmitted in probe response frames in response to a client’s probe requests. Once the client
has acquired the information required to meet the transmit requirements of the regulatory domain, it configures itself for
operation in the regulatory domain.
On some AP models, the regulatory domain and associated parameters are automatically configured when a country is
selected on the System tab. On APs in which country selection is not available on the system tab, the regulatory domain
is pre-programmed into the AP prior to shipment. Depending on the regulatory domain, a default country code is chosen
that is transmitted in the beacon and probe response frames.
Configuring 802.11d Support
Perform the following procedure to enable 802.11d support and select the country code:
1. Click Configure > Interfaces > Operational Mode.
2. Select Enable 802.11d.
