Field | Description |
Automatic 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. |
| Automatic power uses a proprietary algorithm to automatically adjust the RF |
| signal to broadcast far enough to reach wireless clients, but not so far that it |
| interferes with RF signals broadcast by other APs. The power level algorithm |
| increases or decreases the power level in 10% increments based on presence |
| or absence of packet retransmission errors. |
|
|
Initial Power | The automatic power algorithm will not reduce the power below the number |
| you set in the initial power field. By default, the power level is 100%. |
| Therefore, even if you enable the automatic power, the power of the RF |
| signal will not decrease. |
| The power level is a percentage of the maximum transmission power for the |
| RF signal. |

If you access the Access Point Profile Radio configuration through the Advanced Configuration > AP Profile > Radio tab, some additional fields are available for configuration.
The following table describes the fields for the AP radio that are only available from the Advanced Configuration menu.

Field | Description |
RF Scan Duration | This field controls the amount of time the radio spends scanning the other |
| channel (in milliseconds) during an RF scan. |
|
|
Transmit Lifetime | Shows the number of milliseconds to wait before terminating attempts to |
| transmit the MSDU after the initial transmission. |
|
|
Receive Lifetime | Shows the number of milliseconds to wait before terminating attempts to |
| reassemble the MMPDU or MSDU after the initial reception of a fragmented |
| MMPDU or MSDU. |
|
|
Frag Threshold | The fragmentation threshold limits the size of packets transmitted over the |
| network. Acceptable values are even numbers from |
| are under the configured size are not fragmented. A value of 2346 means that |
| packets are not fragmented. |
|
|
Short Retries | The value in this field indicates the maximum number of transmission |
| attempts on frame sizes less than or equal to the RTS Threshold. The range is |
| |
|
|
Long Retries | The value in this field indicates the maximum number of transmission |
| attempts on frame sizes greater than the RTS Threshold. The range is |
