                                          MPE Report

Exposure category: General population/uncontrolled environment
EUT Type: Production Unit
Device Type: Mobile Device
Refer Standard: KDB 447498 D01 General RF Exposure Guidance v06
                FCC Part 2 §2.1091
1. 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 modeled 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.

        P=power input to antenna
        G=power gain of the antenna in the direction of interest relative to an isotropic radiator
        R=distance to the center of radiation of the antenna
From the EUT RF output power, the minimum mobile separation distance, d=0.2m, as well as the
maximum gain of the used 3.5dBi for for 2.4GWLAN and 5.8GWLAN, the RF power density can be
obtained.
