This product is designed for specific application and needs to be installed by a qualified personal
who has RF and related rule knowledge. The general user shall not attempt to install or change
the setting.

Professional Installation Requirements
The following requirements for installation and operation of outdoor systems must be addressed:
Operation in the 5600-5650-MHz band is not authorized for 5-GHz WLAN systems, whether
operating indoors or outdoors. This does not pose a problem for Cisco
®
WLAN since this band is
not accessible for Cisco products.
Use of indoor-only equipment outdoors can lead to FCC enforcement action, such as fines or
requirements to disable the system. This includes installations where the access point is placed
indoors and the antenna is placed outdoors, as well as installations involving retractable roofs
(for example, football stadiums).
For WLAN systems being installed outdoors, the following requirements must be met.
a) Systems must be professionally installed by a qualified engineer familiar with WLAN,
including Cisco trained partners and resellers.
b) Operation in the 5600-5650-MHz band is prohibited.
c) It is recommended that the installer register the installation of their system in the Wireless
Internet Service Providers Association (WISPA database). This is especially important for systems
that are installed within 35 km of the FAA TDWR. (Please see the links later in this document to
WISPA database with TDWR locations.)
d)
When within 35 km distance of a TDWR, the center frequency of the WLAN must be
separated from the TDWR center frequency by 30 MHz.
a. If the radar is operating from 5600-5610 MHz, disable the use of channel 116 (5580 MHz).
b. If the radar is operating from 5630-5650 MHz, disable the use of channel 132 (5660 MHz).
Note: Cisco will be disabling channels 116 and 132 for outdoor systems in the future, the
instructions in (d) only applies to systems that currently have the channels enabled.
e) Additional mitigation techniques can include first, not orienting the antennas in the main
beam of the weather radar, and second, ensuring that the antenna is not positioned in line-of-
sight of the FAA TDWR.
f) Verify that the antennas used are approved for use with Cisco WLAN systems. Installers or
operators using non-approved antennas or making any unauthorized changes may be subject to
enforcement action.
g) Operation in the 5150-5250MHz is restricted to indoor use only.
Installers and operators shall consult the Wireless Internet Service Providers Association (WISPA)
database to determine if they are within 35 km of the Terminal Doppler Weather Radar (TDWR),
as well as to register the system if operating within this range of the TDWR.
For outdoor operation of the AP in the 5150-5250 MHz band , the maximum output power
shall not exceed 1W. EIRP at any elevation angle above 30 degrees (as measured from the
horizon) shall not exceed 125mW, per the FCC Part 15.407 rules. The highest antenna gains
from the horizon above 30 degrees are as below:
