7 RF Exposure Requirements
An estimation of MPE in this application for product is used to ensure if it complies to the
rules of the standard in the regulation list above.
Maximum permissible exposure (MPE) refers to the RF energy that is acceptable for
human exposure. It is broken down into two categories, Occupational/controlled and
General population/uncontrolled.
Occupational/controlled limits apply in situations in which persons are exposed as a
consequence of their employment provided those persons are fully aware of the potential
for
exposure
and
can
exercise
control
over
their
exposure.
Limits
for
occupational/controlled exposure also apply in situations when an individual is transient
through a location where occupational/controlled limits apply provided he or she is made
aware of the potential for exposure.
General population/uncontrolled exposures apply in situations in which the general public
may be exposed, or in which persons that are exposed as a consequence of their
employment may not be fully aware of the potential for exposure or cannot exercise
control over their exposure.
A rough estimation of the expected exposure in power flux density on a given point can be
made with the following equation:
S=
P ×G
4 ×π ×R 2
Where:
S = power density
P = power input to the antenna
G = numeric gain of the antenna in the direction of interest relative to an isotropic
radiator
R= distance to the centre of radiation of the antenna
EIRP = P*G
The antenna of the product, under normal use condition is at least 20 cm away from the

body of the user. Warning statement to the user for keeping at least 20cm separation
distance and the prohibition of operating to a person has been printed on the user’s
manual. Therefore, the S of the device is calculated with R=20cm, and if it is below the
limit S, then we can conclude the device complies with the rules.
7.1
FCC MPE Limits
We analysis if it comply with the limits for General population/uncontrolled exposure. The
FCC MPE limits for field strength and power density are given in 47CFR 1.1310(Table
below).These limits are generally based on recommended exposure guidelines published
by the National Council on Radiation Protection and Measurements (NCRP), and also
partly based on guidelines recommended by the American National Standards Institute
(ANSI) in Section 4.1 of ANSI/IEEE C95.1.

For GSM bands, the time-based average power considering the duty cycle should be
used in MPE evaluation. To average the power, the division factor is as follows:
1Tx slot = 1 transmit time slot out of 8 time slots => power divided by (1/8) = > - 9.03dB
2Tx slots = 2 transmit time slot out of 8 time slots=> power divided by (2/8) = > - 6.02dB
3Tx slots = 3 transmit time slot out of 8 time slots=> power divided by (3/8) = > - 4.26dB
4Tx slots = 4 transmit time slot out of 8 time slots=> power divided by (4/8) = > - 3.01dB
According to the Table, we can conclude the max power density level at 20 cm is
0.198mW/cm², which is below the uncontrolled exposure limit, so we can conclude it is
into compliance.

9 Exposure calculations for multiple sources
When a number of sources at different frequencies, and/or broadband sources, contribute
to the total exposure, it becomes necessary to weigh each contribution relative to the
MPE in accordance with the provisions of Table(A) and Table(B). To comply with the MPE,
the fraction of the MPE in terms of E2, H2 (or power density) incurred within each
frequency interval should be determined and the sum of all such fractions should not
exceed unity.
In order to ensure compliance with the MPE for a controlled environment, the sum of the
ratios of the power density to the corresponding MPE should not exceed unity. That is
Si
∑MPE
i =1
≤1

Note: The GSM/UMTS//LTE Internal antenna and GSM/UMTS/LTE External antenna
cannot transmit simultaneously.
