1. RF EXPOSURE
1.1.The Requirement
System 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 levels in excess
of the Commission’s guidelines. See Section 15.247(b)(4) and Section 1.1307(b)(1)

1.3.MPE Calculation Method
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
From the peak EUT RF output power, the minimum mobile separation distance,
d=0.2m, as well as the gain of the antenna is 0 dBi, the RF power density can be
obtained.

The measurement results comply with the FCC Limit per 47 CFR 2.1091 for the
uncontrolled RF Exposure.
1.5.FCC Radiation Exposure Statement
This equipment complies with FCC radiation exposure limits set forth for an
uncontrolled environment. In order to avoid the possibility of exceeding the FCC radio
frequency exposure limits, Human proximity to the antenna shall not be less than
20cm(8 inches) during normal operation. Proposed RF exposure safety information to
include in User’s Manual.
