FCC Requirements for Operation in the United
States
This device is restricted to
indoor
use only due to its operation in 5150 to 5250 MHz and 5470 to
5725 MHz frequency ranges in accordance with latest FCC regulations.
Host systems using Porxim Firmware with this 802.11 a/b/g/n 3x3 MIMO nimiPCI module to be
sold in the United States do not have country code settings and are factory configured to only
operate on the channels allowed by the FCC. Master devices with a US SKU that contain the 802.11
a/b/g/n Radio module are limited to the following operating channels:
?
1 -11 (2412 to 2462 MHz) in the 2.4 GHz band
?
36 – 64 (5180 to 5320 MHz) in the 5150 to 5350 MHz band
?
100 – 116 (5500 to 5580 MHz) and 132 – 140 (5660 to 5700 MHz) in the 5470 to 5725 MHz
band
?
149 – 165 (5745 to 5825 MHz) in the 5725 to 5825 MHz band
High power radars may use the 5250 to 5350 MHz and 5470 to 5725 MHz frequency ranges in your
area. Such radar stations can cause interference and damage to this device. This radio module
implements a radar detection function which may cause interruption of normal operation when radar
signal is detected.
This equipment has been tested and found to comply with the limits for a Class B digital device,
pursuant to Part 15 of the FCC Rules.
RF Exposure
To ensure compliance with FCC RF exposure requirements, the antennas used for this device
must be installed to provide a separation distance of at least 20 cm from all persons.
Outdoor operations in the 5150~5250MHz, 5600~5650MHz band is prohibited.
This device has no Ad-hoc capability for 5250~5350MHz and 5470~5725MHz.
In order to meet new FCC, NTIA, FAA and industry restrictions to resolve interference to
Terminal Doppler Weather Radar (TDWR) systems used at airports, any outdoor device installed
within 35 km of a TDWR location must be separated by at least 30 MHz (center-to-center) from
TDWR operating frequency (as shown in the table below). Channels 120-132 and 5600-5650
MHz band are disabled on outdoor products.
We recommend that all operators and installers register the location information of the UNII
devices operating outdoors in the 5470 – 5725 MHz band within 35 km of any TDWR location at
the WISPA sponsored database (see http://www.spectrumbridge.com/udia/home.aspx). This
database may be used by government agencies in order to expedite resolution of any interference
to TDWRs.
Procedures on how to register the devices in the industry-sponsored database with the appropriate
information regarding the location and operation of the device and installer information can be
found on the database.
