Test Specific Details
                           The objective of this test session is to perform final qualification testing of the EUT with respect to the
              Objective:
                           specification listed above.
     Date of Evaluation: 3/9/2018
         Test Engineer: David Bare

General Test Configuration
Calculation uses the free space transmission formula:
                            S = (PG)/(4 πd2)
Where: S is power density (W/m2), P is output power (W), G is antenna gain relative to isotropic, d is separation distance from the
transmitting antenna (m).

Summary of Results

                Device complies with Power Density requirements at 20cm
                                                                                     No
                                                            separation:
                                 If not, required separation distance (in cm):       22


Modifications Made During Testing
No modifications were made to the EUT during testing

Deviations From The Standard

Worst case RF exposure is the sum of the ratios for the two radios, 45.8% + 47.7% = 93.5% of the limit.

Worst case MPE value is 0.248 + 0.464 = 0.712 mW/cm2 (7.12 W/m2)
