Allowed Antennas to be used with the Radio Module
The Integrator must request from Atheros sales or regulatory contact person the current list of allowable
antennas for use with the specific radio module. This information is not available on the public FCC database
but will be provided by Atheros. Atheros will provide a table of antenna type(s) models, cable lengths, and
peak gain in each band.
Generally, the list will include Omni-directional Inverted-F (PIFA) and stamped metal/film antennas for use
inside laptops. In some cases, dipole antenna types may be included in the available list. Peak gain including
cable losses are quoted in the table provided by Atheros.
Use of any of the antennas in the list (identical or equivalent antenna with lower gain, dimensions and cable
lengths) is acceptable in the host device, without any further FCC testing or submission.
However, use of an antenna that is higher gain than those on the list or is a Different Type, requires additional
testing and submission to the FCC. Therefore, antennas with higher gain or different type than specified by
Atheros may not be used with the Atheros module until new testing and reporting is completed.

You must contact the Atheros Regulatory Group to report any higher gain or new antenna type to be used with
the module.

Antenna Placement
This 1x1 802.11 a/b/g/n module has been certified by FCC as single module approval with the
following restrictions:
    • The most conservative antenna-to-user separation distance shall be greater than 2 cm to
        end user or near-by person. 2 cm physical separation distance is measured by
        positioning the display section of notebook/Netbook/Laptop computers perpendicular
        to the keyboard section. Measure the distance from the nearest point of antenna to the
        bottom of host.
    • Consult with Atheros to determine the allowable rotational orientations for vertical and
        horizontal antenna installation in applicable host devices.
    • When antenna is installed in the typical notebook/Netbook/laptop computer platform,
        the antenna cable shall be positioned away from antenna elements to conform to
        configuration tested for compliance.
    • When the antennas are installed in the display section of notebook/Netbook/Laptop
        computer platform, the display section shall not have metallic components and material
        that can influence or change the operating and exposure characteristics of the antennas.
If any one of condition listed above can not comply, please consult with Atheros regulatory
contact person to determine the applicable equipment authorization procedure before
marketing the host device.

Simultaneous transmission of Radio Module with Other Integrated or
Plug-In Radios
Based upon FCC Knowledge Database publication number 616217 D03 (Supplement)
https://fjallfoss.fcc.gov/kdb/GetAttachment.html?id=30257, when there are multiple radios
installed in a host device, RF exposure transmitting assessment shall be performed to determine
the necessary application and test requirements. Certain criteria can be used in determine the
requirement for simultaneous SAR evaluation and whether Class I or Class II permissive
change may apply. A brief summary of the procedures is provided below. OEM integrators
must consult the actual FCC KDB 616217 Supplement document for details:
Page 7 of 11


     •   Identify all possible combinations of simultaneous transmission configurations for all
         transmitters and antennas installed in the display screen and keyboard of the intended
         host computer configurations and provide the following information:
              o Antenna-to-antenna separation distance
              o Antenna-to-user separation distance
     •   Transmitters/antennas operating from external card slots and/or connectors of the host
         computers must be more than 5 cm from any simultaneous transmitting antennas
     •   If simultaneous transmission radio/module is installed in the host as portable device ( <
         20 cm to the body of user) , determine the highest 1-g SAR value of each portable radio
         module for applicable simultaneous transmission operating modes and configurations.
     •   If simultaneous radio is installed in the host as mobile device (> 20 cm to the body of
         user) , determine the MPE (power density) according to the highest output power, ,
         antenna gain and antenna-to-user separation distance in each frequency band.
     •   Determine the antenna to antenna separation distances as required for the conditions
         below

     a) When the [(∑ of the highest measured 1-g SAR for each portable transmitter/antenna
        included in the simultaneous transmission configuration) / 1.6 W/kg] + ∑ of [(the
        highest MPE for each mobile transmitter/antenna included in the simultaneous
        transmission configuration) / (the corresponding MPE limit)] < 1; (where: ∑ excludes
        antennas that do not require SAR evaluation, the corresponding MPE limits based upon
        frequency band can be found at table 1 of section 1.1310 of CFR 47:
        http://ecfr.gpoaccess.gov/cgi/t/text/text-
        idx?c=ecfr&sid=788a1f4d7395e22ffa71dc3905fb2f10&rgn=div8&view=text&node=47:1.0
        .1.1.2.9.193.10&idno=47)
or
     b) For antennas included in the simultaneous transmission configuration that require SAR
         evaluation, when the separation distance between each antenna pair is
        i) greater than 5 — [(SAR1 + SAR2) / 1.6]1.5 cm, rounded to the nearest cm, and
        ii) the ∑ of [(the highest MPE for each mobile transmitter/antenna included in the
        simultaneous transmission configuration) / (the corresponding MPE limit)] < 1

By satisfying condition a) or b) as listed above, simultaneous SAR evaluation is not required.
Incorporation of this Atheros module in conjunction with other certified transmitters in a
qualified host device can be addressed as a Class I permissive change. However, the
simultaneous transmission conditions must be fully documented in Class I permissive change
report as described in KDB 616217 Supplement..

For each simultaneous transmission configuration which does not meet the conditions
described above, submit an inquiry to Atheros Regulatory Group or equivalent responsible
party of the radio module to evaluate additional FCC evaluation or application requirements.

Required Information to be documented in the Class I permissive
change report

Page 8 of 11


A summary of the information to be included in the Class I permissive change report is listed
below. OEM integrators must consult the FCC KDB 616217 Supplement document for details.

1. FCC ID of all transmitters, maximum average conducted output power in each transmission
   mode and frequency band, operating configurations and exposure conditions approved for
   the individual transmitters.
2. Applicable antenna locations for all host configurations identified in diagrams, drawings
   and/or photos, including the range of antenna-to-user and antenna-to-antenna separation
   distances to support the required test reduction and exclusion analysis or SAR test
   configurations (The closest distance between each antenna and the user and the closest
   distance between individual antennas should be used.)
3. The type and physical dimensions of antennas incorporated in the intended host
   configurations
4. Antenna gain specified by the antenna manufacturer for antennas qualified for mobile
   exposure conditions

5. Other relevant information and restrictions required by the equipment certifications of
   individual transmitters, including antenna changes
6. The range of applicable physical, mechanical and electrical variations of host computer
   configurations supported by the test results in all relevant equipment certification.

Required Host System Labeling
FCCID and Industry Canada ID
The Integrator must affix the Atheros module’s FCCID on the module. Also, when the module is not visible when
installed in the host system, an additional label must appear on the outside of the host system visible to the user. Industry
Canada (IC) labeling is only required on the module.
Example FCC & Canada IDs to appear on module:
