5       RF Exposure Evaluation

5.1 RF Exposure Compliance Requirement
5.1.1 Limits
         According to FCC Part1.1310: The criteria listed in the following table shall be used to evaluate the
        environment impact of human exposure to radio frequency (RF) radiation as specified in part1.1307(b)




F= Frequency in MHz
Friis Formula
Friis transmission formula: Pd = (Pout*G)/(4* Pi * R2)
Where
Pd = power density in mW/cm2
Pout = output power to antenna in mW
G = gain of antenna in linear scale
Pi = 3.1416

For Uncontrolled Environment, the limit of MPE is 0.2 mW/cm2 . If we know the maximum gain of the antenna
and the total power input to the antenna, through the calculation, we will know the distance r where the MPE
limit is reached.

5.1.2 Test Procedure
Software provided by client enabled the EUT to transmit and receive data at lowest, middle and highest
channel individually.

Then the maximum rated power of half-duplex is 12.5W, the low rated power of half-duplex is 0.5W.
To satisfy RF exposure requirements, a separation distance of 140.72cm or more should be maintained
between this device and persons during device operation. To ensure compliance, operations at closer than this
distance is not recommended.
The minimum distance between this device and persons during device operation is 210 cm which declared by
manufacturer. Through the calculation, the maximum power density at 210cm is:
Pd = (Pout*G)/(4* Pi * R2) =(12501.73*3.98)/(4*3.1416*210*210) = 0.0898 mW/cm2
For AIS Transmitter:
The rated power is 2W, which declared by manufacturer.Then the rated power of half-duplex is 1W.
To satisfy RF exposure requirements, a separation distance of 47.25cm or more should be maintained between
this device and persons during device operation. To ensure compliance, operations at closer than this distance
is not recommended.
The minimum distance between this device and persons during device operation is 210 cm which declared by
manufacturer. Through the calculation, the maximum power density at 210cm is:
Pd = (Pout*G)/(4* Pi * R2) =(1409.19*3.98)/(4*3.1416*210*210) = 0.0101 mW/cm2

The simultaneous transmission result between of 2.4G WiFi, VHF and AIS:
The SAR Exclusion Threshold Level:
=CPD1 / LPD1 + CPD2 / LPD2 + CPD3 / LPD3 (CPD = Calculation power density, LPD = Limit of power density)
= (0.0898/0.2) +(0.0101/0.2) +(0.0100/1)= 0.5095 < 1
Since the SAR Exclusion Threshold Level is well below the SAR low threshold level, so the EUT is considered
to comply with SAR requirement without testing.
