13. Repeat this procedure, changing the value of the Downlink Data parameter until
the values that this tool calculates for the Uplink Rcv SQ Start field are within
300 time bits of each other; if possible, within 150 time bits.
14. Access the Radio tab in the Configuration web page of each AP in the cluster
and change its Downlink Data parameter (percentage) to the last value that you
used in the Frame Calculator.
Viewing the DFS Status Tab (All)
Examples of the DFS Status tab in the Tools page are shown in Figure 186.
Figure 186: DFS Status tab of AP, example
This tab provides an instant view of the current frequency in use and thus whether the Dynamic
Frequency Selection (DFS) feature has shut down operation on the primary frequency to avoid
competition with radar that is protected by regulation.
DFS Event History
This log is useful for seeing when DFS events happened, including the response of any Alternate
RF Carriers that were assigned.
In the example shown in Figure 186, the AP
1. performed a 60-second Channel Availability Check (CAC).
2. started transmitting at 1:03 (mm:ss) on 5580 MHz, the Primary RF Carrier
Frequency.
3. experienced a DFS hit at 6:58:58 (hh:mm:ss).
4. switched to the Alternate RF Carrier Frequency 1 (5590 MHz).
5. performed a 60-second Channel Availability Check (CAC).
