EMC Test Data Client: Google Inc. Job Number: JD104891 T-Log Number: T104956 Model: Model H0A Project Manager: Deepa Shetty Contact: Dominik Mente Project Coordinator: - Standard: FCC 15.247 / 15.407 / RSS-247 Class: N/A Maximum Permissible Exposure 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: 8/8/2017 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 FCC ID: A4RH0A IC: 10395A-H0A T104956 (FCC_IC Radio) MPE Calc Page 1 of 2
