Measurement of MPE

1. Foreword
In adopt with the Human Exposure IEEE C95.1, and according to the FCC 1.1310. The
Maximum Permissible Exposure (MPE) is obligated to measure in order to prove the safety of
radiation harmfulness to the human body.

The Gain of the antenna used is measured in an anechoic chamber. The maximum total
power to the antenna is to be recorded. By adopting the Friis Transmission Formula and the
power gain of the antenna, we can find the distance right away from the product, where the
limit of the MPE is.

According to OET BULLETIN 56 Fourth Edition/August 1999, Equation for Predicting RF Fields:

PG 44.77 × 1.63
Power density at the specific separation (portable): S = = = 0.0145mW / cm 2
4πR 2
4π (20) 2

Where: 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
R = distance to the center of radiation of the antenna (appropriate units, e.g., cm)

The Numeric gain G of antenna with a gain specified in dB is determined by:
G = Log -1 (dB antenna gain/10)
G = Log -1 (2.13 / 10) = 1.63
