FCC ID: 2AHRD--EHWD9905 RF Exposure Applicable Standard According to §1.1307(b)(5), systems operating under the provisions of this section shall be operated in a manner that ensure that the public is not exposed to radio frequency energy level in excess of the Commission’s guideline. This is a Portable device. The Section 4.3.1 and Appendix A of KDB447498 D01 V06 was used as the guidance. 2.4G Band Calculation Result (Worse case—802.11b，Channel 2412MHz) [(max. power of channel, including tune-up tolerance, mW)/(min. test separation distance, mm)] · [√f(GHz)] =5.559/5 * 1.55= 1.72, this value is less than 3.0 for 1-g SAR and ≤ 7.5 for 10-g extremity SAR. 5G Band Calculation Result (Worse case—802.11a，Channel 5825MHz) [(max. power of channel, including tune-up tolerance, mW)/(min. test separation distance, mm)] · [√f(GHz)] =5.047/5 * 2.41= 2.43, this value is less than 3.0 for 1-g SAR and ≤ 7.5 for 10-g extremity SAR. The SAR measurement is not necessary.
