Configuring Wireless Radio Settings 855 Configuring Access Point SettingsIf you access the Access Point Profile Radio configuration through the AdvancedConfiguration > AP Profile > Radio tab, some additional fields are available forconfiguration.The following table describes the fields for the AP radio that are only available from theAdvanced Configuration menu.Automatic Power The power level affects how far an AP broadcasts its RF signal. If the powerlevel is too low, wireless clients will not detect the signal or experience poorWLAN performance. If the power level is too high, the RF signal mightinterfere with other APs within range.Automatic power uses a proprietary algorithm to automatically adjust the RFsignal to broadcast far enough to reach wireless clients, but not so far that itinterferes with RF signals broadcast by other APs. The power level algorithmincreases or decreases the power level in 10% increments based on presenceor absence of packet retransmission errors.Initial Power The automatic power algorithm will not reduce the power below the numberyou 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 RFsignal will not decrease.The power level is a percentage of the maximum transmission power for theRF signal.Table 10. Advanced Radio ConfigurationField DescriptionRF Scan Duration This field controls the amount of time the radio spends scanning the otherchannel (in milliseconds) during an RF scan.Transmit Lifetime Shows the number of milliseconds to wait before terminating attempts totransmit the MSDU after the initial transmission.Receive Lifetime Shows the number of milliseconds to wait before terminating attempts toreassemble the MMPDU or MSDU after the initial reception of a fragmentedMMPDU or MSDU.Frag Threshold The fragmentation threshold limits the size of packets transmitted over thenetwork. Acceptable values are even numbers from 256-2345. Packets thatare under the configured size are not fragmented. A value of 2346 means thatpackets are not fragmented.Short Retries The value in this field indicates the maximum number of transmissionattempts on frame sizes less than or equal to the RTS Threshold. The range is1-255.Long Retries The value in this field indicates the maximum number of transmissionattempts on frame sizes greater than the RTS Threshold. The range is 1-255.Table 9.
