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.
