DFS for 5 GHz Radios
Dynamic Frequency Selection (DFS) is a requirement in several countries and regions for 5 GHz
unlicensed systems to detect radar systems and avoid co-channel operation. DFS and other regulatory
requirements drive the settings for the following parameters, as discussed in this section:
•
Country Code
• Primary Frequency
• Alternate 1 and Alternate 2 Frequencies
• External Antenna Gain
On the AP, the Home > DFS Status page shows current DFS status of all three frequencies and a DFS
log of past DFS events.
Figure 28 AP DFS Status
DFS operation
The ODUs use region-specific DFS based on the Country Code selected on the module’s Configuration,
General page. By directing installers and technicians to set the Country Code correctly, the operator
gains confidence the module is operating according to national or regional regulations without having
to deal with the details for each region.
The details of DFS operation for each Country Code, including whether DFS is active on the AP, SM, and
which DFS regulations apply is shown in
Table 172 on page 4-61 .
