D-Link Unified Access System User Manual Table 9. Radio Settings Field Automatic Power Initial Power Antenna Diversity Description 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. 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. Select the antenna use to receive and transmit wireless traffic: • Auto: Automatically select the best antenna to send and receive traffic. • Primary: Use the primary antenna to send and receive traffic. • Secondary: Use the secondary antenna to send and receive traffic. 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 RF Scan Duration Transmit Lifetime Receive Lifetime Frag Threshold Short Retries Long Retries Description This field controls the amount of time the radio spends scanning the other channel (in milliseconds) during an RF scan. Shows the number of milliseconds to wait before terminating attempts to transmit the MSDU after the initial transmission. 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. 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. 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. 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. 92 © 2001- 2008 D-Link Corporation. All Rights Reserved.
