Bay Area Compliance Laboratories Corp. (Dongguan) Report No.: RDG180807019-00A

FCC §15.247 (i) & §1.1310 & §2.1091- MAXIMUM PERMISSIBLE
EXPOSURE (MPE)
Applicable Standard
According to subpart 15.247(i)and subpart §1.1310, 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.

Limits for Maximum Permissible Exposure (MPE) (§1.1310, §2.1091)

(B) Limits for General Population/Uncontrolled Exposure
Frequency Range Electric Field Magnetic Field Power Density Averaging Time
(MHz) Strength (V/m) Strength (A/m) (mW/cm2) (minutes)
0.3–1.34 614 1.63 *(100) 30
1.34–30 824/f 2.19/f *(180/f²) 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;

According to §1.1310 and §2.1091 RF exposure is calculated.

Calculation formula:

Prediction of power density at the distance of the applicable MPE limit
S = PG/4R² = power density (in appropriate units, e.g. mW/cm2);
P = power input to the antenna (in appropriate units, e.g., mW);
G = power gain of the antenna in the direction of interest relative to an isotropic radiator, the power gain
factor, is normally numeric gain;
R = distance to the center of radiation of the antenna (appropriate units, e.g., cm);

Calculated Data:
