2-2 Enterprise Wireless LAN Antenna Specification Guide
2.1.1 Outdoor Access Point Installations
The FCC regulations for the indoor and outdoor installation are different; the professional installer must
configure the Access Point transmitters accordingly. Products that are specifically intended to be placed
outdoors are configured at the factory for compliant outdoor operation. Motorola Solutions recommends
professional installers review the following to assess the legality of outdoor deplyments:
• If a transmitter is placed indoors but the antenna is placed outdoors, the FCC interprets this as an outdoor
installation
• If a transmitter is placed indoors and the antenna is oriented to intentionally radiate outdoors, the FCC
interprets this as an outdoor installation
• If the transmitter is placed on a loading dock or inside a covered stadium with a retractable cover, the FCC
views this as an outdoor installation
The Federal Communications Commission (FCC), the National Telecommunications and Information
Administration (NTIA) and the Federal Aviation Administration (FAA) have an ongoing investigation of
interference caused to Terminal Doppler Weather Radar (TDWR) systems operating in the 5600-5650 MHz band.
TDWRs are used to detect wind shear and other weather conditions near airports.
The interference at most locations was attributed to fixed wireless transmitters operating outdoors in the
vicinity of airports at high elevations that are line-of-sight to the TDWR installations (5 GHz network equipment).
In some instances, the interference was caused by equipment that was not properly certified or configured. In
other instances, equipment was FCC certified nonetheless caused interference. The FCC has taken appropriate
enforcement action in each of these cases.
If everything is determined to be compliant - the FCC orders the interfering transmitter turned off or adjustments
be made such that there is no more interference; any non-compliance determined is resolved with an
enforcement action.
On 14 OCTOBER 2010 the FCC published the following notice that requests that devices operating in the 5.4 GHz
band located near the appended list of airports register these devices. A voluntary 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.
WARNING! OPERATING A TRANSMITTER THAT IS CONFIGURED FOR
INDOOR USE IN AN OUTDOOR ENVIORNMENT IS AGAINST FCC
REGULATIONS AND SUBJECT TO FCC ENFORCEMENT ACTIONS
AGAINST BOTH THE INSTALLER AND THE OPERATOR.
NOTE: Motorola Solutions strongly encourages the voluntary registration of all outdoor
installations at http://www.spectrumbridge.com/udia/home.aspx
