3. METHOD OF MEASUREMENT

3.1 Applicable Standard
According to §1.1307(b)(1), systems operating under the provisions of this 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.
According to §1.1310 and §2.1091 RF exposure is calculated.
KDB447498 v06: Mobile and Portable Devices RF Exposure Procedures and Equipment Authorization
Policies

3.2 Requirement
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.
