Enable H Band Support
In compliance with FCC regulations, Dynamic Frequency Selection is required in the middle frequency band (M band:
5.26 GHz - 5.32 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.

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. Turbo mode is available only in
802.11a mode in the FCC regulatory domain. Turbo Mode is not available in frequency bands in which DFS is
required.
Turbo mode is supported in 802.11a mode in the FCC regulatory domain when DFS is not required. Turbo mode supports
turbo speeds at twice the standard data rates, and also dynamically switches between Turbo mode speeds and normal
speeds depending on the wireless client. All connected clients must be using Turbo mode in order for the AP to operate
at Turbo mode speed. If turbo mode is enabled, then this is displayed in the web UI and the transmit speeds and
channels pull-down menus are updated with the valid values.
When Turbo mode is enabled, only a subset of the wireless channels in the 5.0 GHz spectrum can be used. If any
wireless clients do not support turbo mode, the AP will fall back to normal mode.
Turbo mode can be configured only when Super mode has already been enabled.
Super mode is supported in the 2.4 GHz and 5 GHz frequency bands in all regulatory domains. Turbo mode is available
in the 5 GHz frequency band in the FCC regulatory domain when DFS is not required.
NOTE: Turbo mode and Mesh mode (either Mesh AP or Mesh Portal) can not be enabled on the same interface
simultaneously.
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.
