Radio Interface

The IEEE 802.11a and 802.11g interfaces include configuration options for radio
signal characteristics and wireless security features. The configuration options are
nearly identical, but depend on which interface is operating as the bridge band. Both
interfaces and operating modes are covered in this section of the manual.

The access point can operate in the following modes:

• 802.11a in bridge mode and 802.11g in access point mode
• 802.11a in access point mode and 802.11g in bridge mode
• 802.11a and 802.11g both in access point mode (no bridging)
• 802.11a only in bridge or access point mode
• 802.11g only in bridge or access point mode

Note that 802.11g is backward compatible with 802.11b and can be configured to
support both client types or restricted to 802.11g clients only. Both wireless
interfaces are configured independently under the following web pages:

• Radio Interface A: 802.11a
• Radio Interface G: 802.11b/g

Note:

The radio channel settings for the wireless bridge are limited by local
regulations, which determine the number of channels that are available.
