Simultaneous transmitting consideration (worst case): The ratio=MPE 2.4G Wi-Fi /limit+MPE 5G Wi-Fi /limit = 0.1519/1+0.5024/1=0.654<1.0, so simultaneous exposure is compliant. To maintain compliance with the FCC’s RF exposure guidelines, place the equipment at least 25cm from nearby persons. Result: Compliant
