5.2 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

5.3 Test Result
The EUT is a mobile device. The power density level at 20 cm is 0.1313 mW/cm², which is below the
uncontrolled exposure limit of 0.558 mW/cm² at 836.52 MHz for Cellular band. The power density level at
20 cm is 0.109 mW/cm², which is below the uncontrolled exposure limit of 1mW/cm² at 1880 MHz for
PCS band.
