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 Test: 8/25/2016
         Test Engineer: Mark Hill

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
                                                                                    Yes
                                                                    ti
                                                            separation:


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

Deviations From The Standard
No deviations were made from the requirements of the standard.



Note: Power values from maximum power plus tune-up tolerance
