5.2.1. Limit(s)

47 CFR 15.231

(e) Intentional radiators may operate at a periodic rate exceeding that specified in paragraph (a) of this section
and may be employed for any type of operation, including operation prohibited in paragraph (a) of this section,
provided the intentional radiator complies with the provisions of paragraphs (b) through (d) of this section,
except the field strength table in paragraph (b) of this section is replaced by the following:

Fundamental Field strength of fundamental Field strength of spurious emission

Linear interpolations.

(b)(1) The above field strength limits are specified at a distance of 3 meters. The tighter limits apply at the band
edges.

(b)(2) Intentional radiators operating under the provisions of this Section shall demonstrate compliance with the
limits on the field strength of emissions, as shown in the above table, based on the average value of the
measured emissions. As an alternative, compliance with the limits in the above table may be based on the
use of measurement instrumentation with a CISPR quasi-peak detector. The specific method of
measurement employed shall be specified in the application for equipment authorization. If average
emission measurements are employed, the provisions in Section 15.35 for averaging pulsed emissions and
for limiting peak emissions apply. Further, compliance with the provisions of Section 15.205 shall be
demonstrated using the measurement instrumentation specified in that section.

(b)(3) The limits on the field strength of the spurious emissions in the above table are based on the fundamental
frequency of the intentional radiator. Spurious emissions shall be attenuated to the average (or,
alternatively, CISPR quasi-peak) limits shown in this table or to the general limits shown in Section 15.209,
whichever limit permits a higher field strength.

5.2.3. Test Data

5.2.3.1. 125 kHz Transmitter

Remarks:

- The measuring receiver shall be tuned over the frequency range 10 kHz to 30 MHz
- Test distance: 0.010 to 30MHz: 10m
- All spurious emissions that are in excess of 20 dB below the specified limit shall be recorded.
- The value measured at 10m shall be extrapolated as applicable to compare with limit and measurement
distance specified in section 15.209(a).
- Measurements were performed at 100m and 30m distances to determine the proper extrapolation factor.

Maximum field strength level at 100m distance: 40.53 dBµV/m
Maximum field strength level at 30m distance: 68.15 dBµV/m

Extrapolation factor:
Difference of measurement between 100 m & 30 m: E = 68.15 – 40.53 = 27.62 dB
E = 20* log(100/30)x = 27.62 dB or x = 27.62 / (20*log(100/30)) = 2.64  (52.8 dB/decade)

- Field strength limit of the fundamental 125 kHz at 300m distance is 20*log(2400/125) = 25.7 dBµV/m
- For frequency 125 kHz, the measured E-Field at 10m (column 3) will be extrapolated to 300m E-Field Level
(column 4) using the extrapolation factor of 52.8*log(10/300) = -77.99 dB

5.4. RF EXPOSURE REQUIRMENTS [§§ 15.247(i), 1.1310 & 2.1091]

§ 1.1310: The criteria listed in the following table shall be used to evaluate the environmental impact of human
exposure to radio-frequency (RF) radiation as specified in 1.1307(b).

Limits for Maximum Permissible Exposure (MPE)

Frequency range Electric field strength Magnetic field strength Power density Averaging time
(MHz) (V/m) (A/m) (mW/cm2) (minutes)
(A) Limits for Occupational/Controlled Exposures
0.3-3.0 614 1.63 *(100) 6
2
3.0-30 1842/f 4.89/f *(900/f ) 6
30-300 61.4 0.163 1.0 6
300-1500 f/300 6
1500-100,000 5 6
(B) Limits for General Population/Uncontrolled Exposure
0.3-1.34 614 1.63 *(100) 30
2
1.34-30 824/f 2.19/f *(180/f ) 30
30-300 27.5 0.073 0.2 30
300-1500 f/1500 30
1500-100,000 1.0 30
f = frequency in MHz
* = Plane-wave equivalent power density

Note 1: 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.

Note 2: 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 can not exercise control over their exposure.

5.4.1. Method of Measurements

Calculation Method of Power Density/RF Safety Distance:

Where, P: power input to the antenna in mW
EIRP: Equivalent (effective) isotropic radiated power.
S: power density mW/cm2
G: numeric gain of antenna relative to isotropic radiator
r: distance to centre of radiation in cm

5.4.2. RF Evaluation

Pursuant to KDB 447498 D01 General RF Exposure Guidance v06, Section 7.2:

Simultaneous transmission MPE test exclusion applies when the sum of the MPE ratios for all simultaneously
transmitting antennas incorporated in a host device is ≤ 1.0, according to calculated/estimated, numerically
modeled, or measured field strengths or power density.

The following table addresses the co-location of all simultaneous transmitters within the EUT at a minimum
separation distance 35 cm

Sum of the MPE ratios for all simultaneously transmitting antennas incorporated within the EUT 0.445
Note: The worst-case configuration (maximum MPE ratio) for each radio module derived from the original radio MPE report was used in the
computation. Refer to these reports for detail.

Conclusion: The sum of the MPE ratios is 0.445 < 1.0, thus the EUT is in compliance with the RF exposure
requirements
