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
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.
