On the AP, the “Home => DFS Status” page shows current DFS status of all three frequencies
and a DFS log of past DFS events. Note, unlike standard Canopy, the PMP 400 and PTP 200
Series AP, SM, and BH do not offer “Whitening”, as the OFDM technology obviates the need for
it.

Background and Operation
The modules use region-specific DFS based on the “Region Code” selected on the module’s
“Configuration => General” page. By directing installers and technicians to set the Region 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.

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.
Available “Region Codes” include Other, United States, Canada, Europe, Brazil, Russia, and
Australia. Operators in regions or countries not listed and with requirements aligned with one of
the listed countries should set the Region Code to that country. Operators in regions or countries
with no requirements for DFS should use the “Other” Region Code.
Australia. Operators in regions or countries not listed and with requirements aligned with one of
the listed countries should set the Region Code to that country. Operators in regions or countries
with no requirements for DFS should use the “Other” Region Code.
New APs and BHMs from the factory will show a Region Code of “None”, and will not transmit
until the Region Code is set to a value other than “None”.
until the Region Code is set to a value other than “None”.
Canada and, for new equipment, Europe, have requirements to avoid certain frequencies used by
some weather radar. To meet this requirement, modules set to a Region Code of Canada or
Europe will display the center channel frequencies shown in Table 3 on page 13 on the AP’s and
BHM’s Carrier Frequency pop-up and on the SM’s and BHS’s Frequency Scan Selection List.

Table 6 shows the details of DFS operation and channels available for each Region Code,
including whether DFS is active on the AP/BHM, SM/BHS, which DFS regulation apply, and any
channel restrictions..
