8.4 PMP 100 SERIES DFS OPERATION BASED ON REGION CODE
For reference, Table 12 shows operating based on Region Code, by frequency band and module
type. Note: 900MHz and 2.4-GHz are not shown as DFS operation does not apply to these frequencies.
Table 12: PMP 100 AP/SM DFS operation based on region code
1. In all cases, set the Region Code to the region you are in, and the software will determine the
correct use of DFS.
2. Terminal Doppler Weather Radar (TDWR) operates on frequencies 5600 through 5650 MHz. In
some countries a “weather notch” is required to avoid impinging on these frequencies.
3. Radios placed on market in Europe after July 1, 2008, can’t impinge on weather radar frequencies.
To meet this requirement, the software checks the date code of the module and implements the
weather notch accordingly. You can tell if a 5.4-GHz module is “newer” or “older” by setting the
Region Code to Europe – if the notch frequencies are not shown on the Configuration => Radio
page, then the module is “newer”, if the notch frequencies are shown, the module is “older”.
