Field | Description |
Channel | The Channel defines the portion of the radio spectrum that the radio uses for |
| transmitting and receiving. The range of channels and the default channel are |
| determined by the Mode of the radio interface and the country in which the |
| APs operate. |
| In the United States, IEEE 802.11b/802.11g modes (802.11 b/g) support use |
| of channels 1 through 11 inclusive, while IEEE 802.11a mode supports a |
| larger set of |
| 153, 157, 161, 165). |
| Interference can occur when multiple access points within range of each |
| other are broadcasting on the same or overlapping channels. The impact of |
| this interference on network performance can intensify during busy times |
| when a large amount of data and media traffic is competing for bandwidth. |
| If you select auto, the AP scans the RF area for occupied channels and selects |
| a channel from the available |
| If you specify a channel, make sure that the channel does not interfere with |
| the channel that neighbor APs use. |
| NOTE: The channel you set for an AP in the valid AP database is fixed and |
| takes precedence over initial channel selection done by the AP and any |
| automatic channel planning done by the switch. |
| NOTE: For radios that use 802.11a mode, some countries have a regulatory |
| domain that requires radar detection. For these countries (based on the |
| country code setting), the radio automatically uses the 802.11h protocol for |
| selecting the channel if radar is detected on the statically assigned channel. |
|
|
Power | The power level affects how far an AP broadcasts its RF signal. If the power |
| level is too low, wireless clients will not detect the signal or experience poor |
WLAN performance. If the power level is too high, the RF signal might interfere with other APs within range.
The default value of 0 indicates that the AP uses the power level set in the AP profile.
NOTE: The power level you set for an AP in the valid AP database is fixed and takes precedence over any automatic power adjustments done by the AP or the switch.
