Operational Mode
From this tab, you can configure and view the operational mode for the Wireless Interface.
The Wireless (802.11a/b/g) interface can be configured to operate in the following modes:
•
802.11b mode only: The radio uses the 802.11b standard only.
• 802.11g mode only: The radio is optimized to communicate with 802.11g devices. This setting will provide the best results if this radio
interface will only communicate with 802.11g devices.
• 802.11b/g mode: This is the default mode. Use this mode if you want to support a mix of 802.11b and 802.11g devices.
• 802.11 a only mode: The radio uses the 802.11a standard only.
NOTE
In countries in which 802.11a (5 GHz) is not available for use, the AP-700 provides dual-band (802.11b and 802.11g) support only.
802.11a functionality covered in this User Guide is not supported.
In general, you should use either 802.11g only mode (if you want to support 802.11g devices only) or 802.11b/g mode to support a mix of
802.11b and 802.11g devices.
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:
•
802.11g only mode
• 802.11b/g mode
• 802.11a only mode
Note: Super Mode and Turbo Mode are not available in operational modes 802.11b and 802.11g-wifi.
Dynamic Turbo mode is supported in 802.11a and 802.11g mode. Dynamic turbo mode support turbo speeds at twice the standard 802.11a/g
data rates, and also dynamically switches between turbo mode speeds and normal speeds depending on the wireless client. 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 on both the 2.4 GHz and 5.0 GHz spectrum can be used.
Turbo mode can be configured only when Super Mode has already been enabled.
The Super G/A mode and Turbo G mode are supported in all regulatory domains. However, Turbo A mode is not available in the Japan
regulatory domain.
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.
The Wireless NIC determines the regulatory domain the AP is operating in. If the AP has dual Wireless NICs, the NIC in Slot A determines the
regulatory domain. 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.
3. Select the Country Code from the ISO/IEC 3166-1 CountryCode drop-down menu.
4. Click OK.
5. Configure Transmit Power Control and transmit power level if required.
