2.0 FCC RULES CONCERNING MAXIMUM PERMISSIBLE RF EXPOSURE:
                    § CFR 47 1.1310 Radiofrequency radiation exposure limits.
The criteria listed in table 1 shall be used to evaluate the environmental impact of human exposure to radiofrequency (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 of this
chapter. Further information on evaluating compliance with these limits can be found in the FCC’s OST/OET Bulletin Number 65,
‘‘Evaluating Compliance with FCC-Specified Guidelines for Human Exposure to Radiofrequency Radiation.’’

NOTE TO INTRODUCTORY PARAGRAPH:
These limits are generally based on recommended exposure guidelines published by the National Council on Radiation Protection and
Measurements (NCRP) in ‘‘Biological Effects and Exposure Criteria for Radiofrequency Electromagnetic Fields,’’ NCRP Report No. 86,
Sections 17.4.1, 17.4.1.1, 17.4.2 and 17.4.3. Copyright NCRP, 1986, Bethesda, Maryland 20814. In the frequency range from 100 MHz to
1500 MHz, exposure limits for field strength and power density are also generally based on guidelines recommended by the American
National Standards Institute (ANSI) in Section 4.1 of ‘‘IEEE Standard for Safety Levels with Respect to Human Exposure to Radio Frequency
Electromagnetic Fields, 3 kHz to 300 GHz,’’
ANSI/IEEE C95.1–1992, Copyright 1992 by the Institute of Electrical and Electronics Engineers.




3.0 UUT POWER OUTPUT / ANTENNA GAIN / SEPARATION DISTANCE
The maximum output power from Exhibit 5-1 is measured as 22.22 dBm.
The duty cycle from Exhibit 3 is 7.136%, or 11.47 dB [10log(0.07136)]
The max antenna gain between the two antennas is 4.98 dBi
Assumed separation distance is 20cm
3.1 MPE CALCULATIONS:

FCC GENERAL POPULATION / UNCONTROLED EXPOSURE LIMITS:
  FOR 300 MHz to 1,500 MHz use F / 1500 mW/cm 2;
  FOR 1,500 to 100,000 MHz use 1 mW/cm 2
EQUATIONS:
MAX AVG EIRP (mW) = 10{(MAX COND PWR. + ANT GAIN + DUTY FACTOR)/10)}
THE FRIIS TRANSMISSION EQUATION = EIRP X DUTY CYCLE / ( 4 X PI X 20 CM 2 )
