If we know the maximum gain of the antenna and total power input to the antenna, through the calculation, we will know the distance where the MPE limit is reached. - Page 6 of 6 - Report No.: MTi210608015-02E3 Address: 101, No. 7, Zone 2, Xinxing Industrial Park, Fuhai Avenue, Xinhe Community, Fuhai Street, Bao’ an District, Shenzhen, Guangdong, China.
