Table 9. Radio Settings

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.

Table 10. Advanced Radio Configuration

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.
