FCC RF Exposure evaluation for mobile devices
Devices operating in standalone mobile device exposure conditions may contain a single transmitter or multiple
transmitters that do not transmit simultaneously. A minimum test separation distance ≥ 20 cm is required between the
antenna and radiating structures of the device and nearby persons to apply mobile device exposure limits. The distance
must be at least 20 cm and fully supported by the operating and installation configurations of the transmitter and its
antenna(s), according to the source-based time-averaged maximum power requirements of § 2.1091(d)(2). In cases where
cable losses or other attenuations are applied to determine compliance, the most conservative operating configurations and
exposure conditions must be evaluated. The minimum test separation distance required for a device to comply with mobile
device exposure conditions must be clearly identified in the installation and operating instructions, for all installation and
exposure conditions, to enable users and installers to comply with RF exposure requirements. For mobile devices that have
the potential to operate in portable device exposure conditions, similar to the configurations described in § 2.1091(d)(4), a
KDB inquiry is required to determine the SAR test requirements for demonstrating compliance.
When a device qualifies for the categorical exclusion provision of § 2.1091(c), the minimum test separation distance may
be estimated, when applicable, by simple calculations according to plane-wave equivalent conditions, to ensure the
transmitter and its antenna(s) can operate in manners that meet or exceed the estimated distance. The source-based timeaveraged maximum radiated power, according to the maximum antenna gain, must be applied to calculate the field strength
and power density required to establish the minimum test separation distance. When the estimated test separation distance
becomes overly conservative and does not support compliance, MPE measurement or computational modeling may be used
to determine the required minimum separation distance.
According to §1.1310 Radiofrequency radiation exposure limits, paragraph (e), the limits for Maximum Permissible
Exposure (MPE) to radiofrequency electromagnetic fields are:

Multiple frequencies assessment
When multiple sources are introduced into an environment, it becomes necessary to address the sources
interdependently, since each source will contribute some percentage of the maximum exposure toward the
total exposure at a fixed location. The sum of the ratios of the exposure from each source to the corresponding
maximum exposure for the frequency of each source must be evaluated.
The exposure complies with the maximum permissible exposure if the sum of the ratios is less than unity:

i 1
Si
MPE
<1
Where
Si
is the power density of each source;
MPEi is the power density basic restriction of each source.
The device can transmit using 25K0F1D and cellular technologies at the same time, so the worst case for
simultaneous transmission will be:
0.00015 0.199

Multiple frequencies assessment
When multiple sources are introduced into an environment, it becomes necessary to address the sources
interdependently, since each source will contribute some percentage of the maximum exposure toward the
total exposure at a fixed location. The sum of the ratios of the exposure from each source to the corresponding
maximum exposure for the frequency of each source must be evaluated.
The exposure complies with the maximum permissible exposure if the sum of the ratios is less than unity:

i 1
Si
MPE
<1
Where
Si
is the power density of each source;
MPEi is the power density basic restriction of each source.
The device can transmit using 25K0F1D and cellular technologies at the same time, so the worst case for
simultaneous transmission will be:
0.0015 1.99
= 0.00055+0.771=0.772 < 1 Limit
