CALCULATIONS

Given
E =  (30 * P * G) / d
and
S = E ^ 2 / 3770
where
E = Field Strength in Volts/meter
P = Power in Watts
G = Numeric antenna gain
d = Distance in meters
S = Power Density in milliwatts/square centimeter
Combining equations and rearranging the terms to express the distance as a function of the remaining
variables yields:
d =  ((30 * P * G) / (3770 * S))

Changing to units of Power to mW and Distance to cm, using:
P(mW) = P (W) / 1000 and
d (cm) =100 * d (m)
yields
d = 100 *  ((30 * (P / 1000) * G) / (3770 * S))
d = 0.282 *  (P * G / S)
where
d = distance in cm
P = Power in mW
G = Numeric antenna gain
S = Power Density in mW/cm^2
Substituting the logarithmic form of power and gain using: P
(mW) = 10 ^ (P (dBm) / 10) and
G (numeric) = 10 ^ (G (dBi) / 10)
yields
d = 0.282 * 10 ^ ((P + G) / 20) /  S Equation (1)
S = 0.0795 * 10 ^ ((P + G)/10)/ d^2 Equation (2)
where
d = MPE distance in cm
P = Power in dBm
G = Antenna Gain in dBi
S = Power Density Limit in mW/cm^2

Equation (1) and the measured peak power is used to calculate the MPE distance.
Equation (2) and the measured peak power is used to calculate the Power density.

LIMITS

From §1.1310 Table 1 (B),
for Public S = 1.0 mW/cm2
for Professional, S = 5.0 mW/cm2

RESULTS

No non-compliance noted:

For this EUT, P+G=5.01-4=1.01dBm, and d=5mm ( handheld device)

Plug all three items into equation (2), yielding,

Power Density Output Antenna] Power

FCC 47 CFR 2.1093 SAR Exclusion Calculation

As per FCC KDB 447498 D01 General RF Exposure Guidance DR03-41372
(All power readings below reflect 1dB addition to account for radio tolerance)

Max. EIRP=1.01+1=2.01dBm, i.e. 0.0016W=1.6mW. Per FCC KDB 447498 D01 General RF
Exposure Guidance v06, Appendix A, SAR Test Exclusion Threshold @2450MHz band for
d=5mm is 10mW. We can conclude that this handheld device is exempt from SAR test.

NOTE: For mobile or fixed location transmitters, the minimum separation distance is 20 cm, even if calculations
indicate that the MPE distance would be less.

7.4 AVERAGE OUTPUT POWER

AVERAGE POWER LIMIT

Section 15.247 permits the maximum conducted (average) output power to be measured as an alternative
to the maximum peak conducted output power for demonstrating compliance to the limit. When this
option is exercised, the measured power is to be referenced to the OBW rather than the DTS bandwidth
(see ANSI C63.10 for measurement guidance).

TEST PROCEDURE per FCC KDB 558074D01v05r02

Measurement Procedure for Fundamental Emission Output Applicable to this EUT
Power
8.3.2.2 Maximum Conducted (average) Output Power Level *
Measurement Procedure Option 1 (Measurement using a
spectrum analyzer (SA): per Subclause 11.9.2.2 of ANSI C63.10
8.3.2.3 Maximum Conducted (average) Output Power Level *
Measurement Procedure Option 2 (using a power meter(PM):
per Subclause 11.9.2.3 of ANSI C63.10
* Alternative method. EUT shall be configured to transmit continuously (min. 98% duty cycle at full power). The
spectrum analyzer shall be set for bin-to-bin spacing ≤RBW/2.

The transmitter output is connected to a RF broadband power meter.

RESULTS

No non-compliance noted:
