RF Exposure Evaluation
LIMIT
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 1.1310(e)
Limits for Maximum Permissible Exposure (MPE)
Electric field
Frequency range Magnetic field strength Power density Averaging time
strength 2
(MHz) (A/m) (mW/cm ) (minutes)
(V/m)
(A) Limits for Occupational/Controlled Exposures
0.3–3.0 614 1.63 *(100) 6
2
3.0–30 1842/f 4.89/f *(900/f ) 6
30–300 61.4 0.163 1.0 6
300–1500 - - f/300 6
1500–100,000 - - 5 6
(B) Limits for General Population/Uncontrolled Exposure
0.3–1.34 614 1.63 *(100) 30
2
1.34–30 824/f 2.19/f *(180/f ) 30
30–300 27.5 0.073 0.2 30
300–1500 - - f/1500 30
1500–100,000 - - 1.0 30
Note: f = frequency in MHz

EVALUATION METHOD
2
Transmission formula: Pd = (Pout*G)/(4*pi*r )
Where
2
Pd = power density in mW/cm , Pout = output power to antenna in mW, G = gain of antenna in linear scale;
Pi = 3.1416, R = distance between observation point and center of the radiator in cm

TEST RESULT

Passed Not Applicable

Maximum conducted Power Density Safety
Test Channel Antenna Gain (dBi)
output power(dBm) Limit (mW/cm2) Distance(cm)

CHL(CH1001) 43.90 3.00 0.20 139.598

CHM2(CH16) 43.90 3.00 0.20 139.598

CHH(CH88) 43.90 3.00 0.20 139.598

Note:
1) If the antenna gain is 3dBi,The exposure safety distance is at least 139.598cm.
