Chapter 3: System planning Radio spectrum planning
Avoidance of weather radars (USA only)
To comply with FCC rules (KDB 443999: Interim Plans to Approve UNII Devices Operating in the
5470 - 5725 MHz Band with Radar Detection and DFS Capabilities), units which are installed within
35 km (22 miles) of a Terminal Doppler Weather Radar (TDWR) system (or have a line of sight
propagation path to such a system) must be configured to avoid any frequency within +30 MHz or
–30 MHz of the frequency of the TDWR device.
This requirement applies even if the master is
outside the 35 km (22 miles) radius but communicates with outdoor clients which may be within
the 35 km (22 miles) radius of the TDWRs.
If interference is not eliminated, a distance limitation based on line-of-sight from TDWR will need
to be used. Devices with bandwidths greater than 20 MHz may require greater frequency
separation.
When planning a link in the USA, visit http://spectrumbridge.com/udia/home.aspx
, enter the
location of the planned link and search for TDWR radars. If a TDWR system is located within 35 km
(22 miles) or has line of sight propagation to the PTP device, perform the following tasks:
• Register the installation on http://spectrumbridge.com/udia/home.aspx.
• Make a list of channel center frequencies that must be barred, that is, those falling within
+30 MHz or –30 MHz of the frequency of the TDWR radars.
The affected channels must be barred as described in Barring channels on page 7-31.
