FCC Guidelines for WLANs Operating in the 5470-5725 MHz Band
2 FCC Guidelines
The FCC, FAA, National Telecommunications and Information Administration
(NTIA) and industry are working to resolve interference to Terminal Doppler
Weather Radar (TDWR) systems used near airports that has occurred from
some outdoor wireless systems operating in the 5470 MHz – 5725 MHz band.
To protect TDWR operations, installers and operators must ensure the following
guidelines are met:
• Devices must not transmit on channels which overlap the 5600 – 5650
MHz band.
• Devices intended for outdoor use are further restricted, as follows:
0
Devices must be professionally installed when operating in the 5470
– 5725 MHz band.
0
Any installation of either a master or a client device within 35 km of a
TDWR location must be separated by at least 30 MHz (center-to-center)
from the TDWR operating frequency as shown in Table 1.
0
If the device is installed within 35 km of multiple TDWRs, the device
must ensure that it avoids operation within 30 MHz for each of the
TDWRs. This requirement applies even if the master is outside the 35
km radius but communicates with outdoor clients which may be within
the 35 km radius of the TDWRs.
Additional mitigation techniques include not orienting the antennas in the main
beam of the weather radar and ensuring that the antenna is not positioned in
line-of-sight of the FAA TDWR.
A voluntary Wireless Internet Service Providers Association (WISPA)
sponsored database has been developed that allows operators and installers
to register the location information of the UNII devices operating outdoors
in the 5470 – 5725 MHz band within 35 km of any TDWR location (see
ttp://www.spectrumbridge.com/udia/home.aspx). This database may be used
h
by government agencies in order to expedite resolution of any interference to
TDWRs.
Ericsson strongly recommends that all operators and installers register in
this WISPA database the location information of the UNII devices operating
outdoors in the 5470 – 5725 MHz band within 35 km of any TDWR location.
Procedures on how to register the devices in the database with the appropriate
information regarding the location and operation of the device and installer
information can be found on the database.
