EUT RF Exposure The Max Conducted Peak Output Power is -2.36dBm (0.58mW) in Highest channel (2402MHz); The gain of the antenna is 2.78dBi. 2.78dBi logarithmic terms convert to numeric result is nearly 1.91. According to formula to calculate the EIRP test result: EIRT=P x G = 0.58 x 1.91 = 0.0011mW 1 SAR Requirement: S=60/f(GHz) = 60/2.402 = 24.98mW 2 1 11 1＜ ＜＜ ＜2 22 2 So SAR report is not required.
