FCC MPE Evaluation Report

2. MPE (Maximum Permissible Exposure) Assessment
2.1 Introduction
According to 47 CFR §2.1091, a mobile device is defined as a transmitting device designed to be used in other than
fixed locations and to generally be used in such a way that a separation distance of at least 20 cm is normally
maintained between the transmitting antenna and the body of the user or nearby persons. In this context, the term
“fixed location” means that the device is physically secured at one location and is not able to be easily moved to
another location. Transmitting devices designed to be used by consumers or workers that can be easily re-located,
such as wireless devices associated with a personal computer, are considered to be mobile devices if they meet the
20 cm separation requirement. The limits to be used for MPE evaluation are specified in §1.1310. All unlicensed
personal communications service (PCS) devices and unlicensed NII devices shall be subject to the limits for general
population/uncontrolled exposure.


2.2 RF Radiation Exposure Limits
According to 47 CFR §1.1310, the criteria listed in below table shall be used to evaluate the environmental impact of
human exposure to RF radiation as specified in §1.1307(b), except in the case of portable devices which shall be
evaluated according to the provisions of §2.1093.

                                 Limits for maximum permissible exposure (MPE)
Notes:
1. f = frequency in MHz
2. Occupational/controlled limits apply in situations in which persons are exposed as a consequence of their
   employment provided those persons are fully aware of the potential for exposure and can exercise control over
   their exposure. Limits for occupational/controlled exposure also apply in situations when an individual is transient
   through a location where occupational/controlled limits apply provided they are made aware of the potential for
   exposure.
3. General population/uncontrolled exposures apply in situations in which the general public may be exposed, or in
   which persons that are exposed as a consequence of their employment may not be fully aware of the potential
   for exposure or cannot exercise control over their exposure.

FCC MPE Evaluation Report


2.3 MPE Assessment Method
Calculations can be made to predict RF field strength and power density levels around typical RF sources. For
example, in the case of a single radiating antenna, a prediction for power density in the far-field of the antenna can
be made by use of the general Equations below. This equation is generally accurate in the far-field of an antenna but
will over-predict power density in the near field, where they could be used for making a "worst case" or conservative
prediction.




Where
S = Power Density, unit in mW/cm2
P = Power input to the antenna, unit in 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, unit in cm
EIRP = Effective isotropically radiated power


2.4 MPE Calculation for Standalone Operations
The manufacturer expects that the radiated component of this device will not close to the human body during normal
usage and the warning statement was also stated in the user instruction. Since the transmitting antenna will be kept
at least 20 cm away from the human body, the MPE level is calculated based on this condition and the result is listed
in below table.

Summary:
Since the ERP (effective radiated power) operated at < 1.5 GHz is less than 1.5 watts and > 1.5 GHz is less than 3
watts, the routine environmental evaluation is not required, and the MPE result calculated for this device complies
with the MPE limit as specified in 47 CFR §1.1310.
