To Whom It May Concern:


We, Qualcomm Atheros, Inc. hereby apply for Class II permission change to the
approved product under FCC ID: PPD-AR5B225 (IC ID: 4104A-AR5B225), to portable
category when applied in the laptop platform Brand Name: Asus/Model Name:TP550L,
J550L and R554L, Due to the design of the platform resulting in less than 20cm distance
to human body, We have tested the platform with the FCC ID: PPD-AR5B225 (IC ID:
4104A-AR5B225) device for SAR. Radiated emission testing was not additionally
performed due to the following:
   The product with FCC ID: PPD-AR5B225 (IC ID: 4104A-AR5B225) module was
    assessed compliant to radiated emission limits per 15.247 in its initial FCC approval
   Original FCC testing was performed with an antenna of higher gain. The current platform
    under application uses an antenna of the same type but of lower gain across the emission
    bands. Hence it is apparent that the current platform yields lower level of radiated emission.
   The original FCC testing on module under FCC ID: PPD-AR5B225 (IC ID: 4104A-
    AR5B225) was performed when the antenna was connected to the module in an open
    environment. The current platform under application has the antenna installed inside the
    laptop enclosure. The physical restraints introduced by the laptop enclosure should have
    resulted in equal or lower level of radiated emission.
Please kindly review the application documents submitted and grant approval for this
permissive change application


Sincerely yours,




Stanley Lin, Global Product Compliance
