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

f = frequency in MHz; * = Plane-wave equivalent power density

Calculated Formulary:
Predication of MPE limit at a given distance

S = PG/4πR² = 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);

For simultaneously transmit system, the calculated power density should comply with:

Note:

The output power was declared by manufacturer (Bluetooth conducted power is -0.3dBm, antenna gain is 4.9dBi)

The three 60GHz radio and Bluetooth can transmit simultaneously:




= 0.3349/1.00 + 0.2018/1.00 + 0.4216/1.00 + 0.0004/1.00
= 0.3349 + 0.2018 + 0.4216 + 0.0004
= 0.9585 < 1.0

Result: The device complied with the applicable MPE Limit at the 25 cm distance.
