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 256-2345. Packets that
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
1-255.
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 1-255.
