Configuring Radio Channel Settings
Note Aironet extensions must be enabled to limit the power level on associated client devices. Aironet
extensions are enabled by default.
Configuring Radio Channel Settings
The default channel setting for the radio is least congested; at startup, the WMIC scans for and selects
the least-congested channel. For most consistent performance after a site survey, however, we
recommend that you assign a static channel setting to each bridge. The channel settings on your WMIC
correspond to the frequencies available in your regulatory domain. See Appendix B, “Channels and
Antenna Settings,” for the frequencies allowed in your domain.
IEEE 802.11g (2.4-GHz Band)
The radio operates on 11 channels from 2412-MHz to 2462-MHz. Each channel covers 5 MHz, and the
bandwidth for the channels overlaps slightly. For best performance, use channels that are not adjacent
(such as 2412 and 2417) for bridges that are close to each other.
Beginning in privileged EXEC mode, follow these steps to set the WMIC’s radio channel:
