Standard Requirement 15.247(b)(4) requirement: The conducted output power limit specified in paragraph (b) of this section is based on the use of antennas with directional gains that do not exceed 6dBi. Except as shown in paragraph (c) of this section. if transmitting antennas of directional gain greater than 6dBi are used. the conducted output power from the intentional radiator shall be reduced below the stated values in paragraphs (b)(1). (b)(2). and (b)(3) of this section. as appropriate. by the amount in dB that the directional gain of the antenna exceeds 6dBi. 2. Limits According to KDB447498 General RF Exposure Guidance v05 Report No. : LK15FR-0523E-2 Page 2 of 2 Shenzhen Laker Testing Technology Co.,Ltd 4D,Block 1,Sunshine Huayi Building,Nanhai West Road,Nanshan, Shenzhen, China TEL:0755-86307736 FAX:0755-86307356 3. EUT RF Exposure The Max Conducted Peak Output Power is 3.45dBm(2.21mW) in middle channel, and the Max Conducted Average Output Power is less than 2.21mW. The best case gain of the antenna is 0dBi. 0 dBi logarithmic terms convert to numeric result is nearly 1. According to the formula. calculate the EIRP test result: EIRP< P x G = 2.21mW x 1 = 2.21mW ① SAR requirement: Limit = 10mW @ 5mm ② ; ① < ②. So the SAR report is not required.
