Page 15 of 30 3.2 Equivalent isotropic radiated power FCC Rule: 15.247(b)(3) EIRP = max. conducted output power + antenna gain EIRP = -3.92 dBm + (2 dBi) = -1.92 dBm Limit: EIRP = +36 dBm for Antenna gain <6dBi Test equipment used: ETSTW-RE 055 3.3 RF Exposure Compliance Requirements Conclusion: No Evaluation required if power is below this threshold: F(GHz) mW Low 2.402 High 2.480 24.58 Maximum measured transmitter power: Conducted Power -3.92dBm (0.40551 mW) EIRP Power - 1.92 dBm (0.64269 mW)  The antenna is PCB antenna, antenna gain is 2 dBi. Threshold for no SAR evaluation is 24.58 mW. Conclusion: No SAR evaluation required since Transmitter output power is below FCC threshold.

Page 2 of 30 1 General Information 1.1 Notes The purpose of conformity testing is to increase the probability of adherence to the essential requirements or conformity specifications, as appropriate. The complexity of the technical specifications, however, means that full and thorough testing is impractical for both technical and economic reasons. Furthermore, there is no guarantee that a test sample which has passed all the relevant tests conforms to a specification. Neither is there any guarantee that such a test sample will interwork with other genuinely open systems. The existence of the tests nevertheless provides the confidence that the test sample possesses the qualities as maintained and that is performance generally conforms to representative cases of communications equipment. The test results of this test report relate exclusively to the item tested as specified in 1.5. The test report may only be reproduced or published in full. Reproduction or publication of extracts from the report requires the prior written approval of the Worldwide Testing Services(Taiwan) Co., Ltd. Specific Conditions: Usage of the hereunder tested device in combination with other integrated or external antennas requires at least additional output power measurements, spurious emission measurements, conducted emission measurements (AC supply lines) and radio frequency exposure evaluations for each individual configuration performed, for certification by FCC.
