4 §15.247 (i) and § 2.1091 - RF Exposure
According to §15.247(i) and §1.1307(b)(1), 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.

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

4.1 MPE Prediction

Predication of MPE limit at a given distance

Equation from page 18 of OET Bulletin 65, Edition 97-01

S = PG/4πR²

Where: S = power density
P = power input to antenna
G = power gain of the antenna in the direction of interest relative to an isotropic radiator
R = distance to the center of radiation of the antenna

The predicted power density level at 20 cm is 0.307 mw/cm2 which is below the uncontrolled exposure limit
of 1.0 mW/cm2. The EUT is used at least 20 cm away from user’s body. It is determined as mobile equipment
and complies with the MPE limit.
