Except as shown in paragraph (c) of this section. if transmitting antennas of directional gain greater than 6 dBi 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 6 dBi. 1.1.2 EUT RF Exposure The Max Conducted Peak Output Power is 3.94dBm (2.477mW) at the Lowest channel ; The best case gain of the antenna is -2dBi. -2dBi corresponds to linear antenna gain : 0.63 According to the formula, the calculation the EIRP test result: EIRP= P x G = 2.477mW x 0.63= 1.56mW ① SAR requirement: S= 60 / f(GHz) = 60/2.402 = 144.12mW ② ; ① < ②. So the SAR measurement is not required.
