TEST REPORT


2.2 Assessment Results

Power density (S) is calculated according to the formula:
S = P / (4πR² )
Where S = power density in mW/cm²
         P = Radiated transmit power in mW
         G = numeric gain of transmit antenna
         R = distance (cm)

As we can see from the test report 190700517SHA-001:
The maximum radiated power = 20.36dBm = 108.64 mW;
Here R is chosen to be 20cm,

S = P / (4πR²) = 108.64 / (4 * 3.14 * 20 * 20) = 0.0216 mW/cm² < 1 mW/cm²

TEST REPORT


Appendix I

Definition below must be outlined in the User Manual:

To satisfy FCC RF exposure requirements, a separation distance of 20 cm or more should be
maintained between the antenna of this device and persons during device operation.
To ensure compliance, operations at closer than this distance is not recommended.
