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 * R 2)
Where
Pd = power density in mW/cm2
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
Pd id the limit of MPE, 1 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.

4.1.3 EUT RF Exposure Evaluation

Antenna Gain: 3.08dBi
Antenna Gain: The maximum Gain measured in fully anechoic chamber is 2.03 in linear scale.
The normal conducted output power is 7.9dBm (tolerance: +/- 2dB).
 Max Conducted Output Power Power Density              Limit     Result
     Peak Output                          to Antenna                       at R = 20 cm
    Power (dBm)                                 (mW)                          (mW/cm2)
              9.90                               9.77                             0.004                         1.0            PASS


Note:
The distance r (3rd column) calculated from the Fries transmission formula is far greater than 20 cm
separation requirement.
