2. Evaluation Method
Systems operating under the provisions of FCC 47 CFR section shall be operated in a manner that ensures
that the public is not exposed to radio frequency energy level in excess of the Commission’s guidelines.
In accordance with 47 CFR FCC Part 2 Subpart J, section 2.1091 this device has been defined as mobile
device whereby a distance of 0.2m normally can be maintained between the user and the device, and below
RF Permissible Exposure limit shall comply with.

In accordance with KDB447498D01 for Simultaneous transmission MPE test exclusion applies when the sum
of the MPE ratios for all simultaneous transmitting antennas incorporated in a host device, based on the
calculated/estimated, numerically modelled or measured field strengths or power density, is ≤ 1.0. The MPE
ratio of each antenna is determined at the minimum test separation distance required by the operating
configurations and exposure conditions of the host device, according to the ratio of field strengths or power
density to MPE limit, at the test frequency. Either the maximum peak or spatially averaged results from
measurements or numerical simulations may be used to determine the MPE ratios. Spatial averaging does not
apply when MPE is estimated using simple calculations based on far-field plane-wave equivalent conditions.
The antenna installation and operating requirements for the host device must meet the minimum test
separation distances required by all antennas, in both standalone and simultaneous transmission operations,
to satisfy compliance.

8.1 Standalone MPE

As declared by the Applicant, the EUT is a wireless device used in a fix application, at least 20 cm from any
body part of the user or nearby persons; from the maximum EUT RF output power, the minimum separation
distance, r =20cm, as well as the gain of the used antenna refer to antenna information, the RF power density
can be obtained.

Remark:
1. Output power (Peak) including tune-up tolerance;
2. MPE evaluate distance is 20cm from user manual provide by manufacturer;


8.2 Simultaneous Transmission MPE

The sample only support one WLAN modular and one antenna, no need consider simultaneous
transmission;


9. Conclusion

The measurement results comply with the FCC Limit per 47 CFR 2.1091 for the uncontrolled RF Exposure of
mobile device.
