2. Evaluation method and Limit

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.
