EUT RF Exposure The Max Conducted Peak Output Power is 3.64dBm (2.31mW) in Middle channel (2.441GHz); The best case gain of the antenna is 2dBi. 2dBi logarithmic terms convert to numeric result is nearly 1.58 According to formula. Calculate the EIRP test result: EIRP= P x G=2.31x1.58=3.65mW ① SAR requirement: S=60/f(GHz)=60/2.441=24.58mW ②; ① < ②. So the SAR report is not required.
