Bay Area Compliance Laboratories Corp. (Shenzhen) Report No.: RSC180929005-00A

FCC §15.247 (i) & §2.1091- MAXIMUM PERMISSIBLE EXPOSURE (MPE)
Applicable Standard
According to subpart 15.247 (i) and subpart 2.1091 systems operating under the provisions of this section
shall be operated in a manner that ensures the public is not exposed to RF energy level in excess of the
communication guidelines.

4R 2
S = 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)
