RF EXPOSURE EVALUATION REPORT Report No. : FA960638 3. RF Exposure Limit Introduction According to ANSI/IEEE C95.1-1992, the criteria listed in Table 1 shall be used to evaluate the environmental impact of human exposure to radio frequency (RF) radiation as specified in §1.1310. The MPE was calculated at 20 cm to show compliance with the power density limit. The following formula was used to calculate the Power Density: 𝐏𝐆 𝐒= 𝟒𝛑𝐑𝟐 Where: S = Power Density P = Output Power at Antenna Terminals G = Gain of Transmit Antenna (linear gain) R = Distance from Transmitting Antenna TEL : 886-3-327-3456 Page : 6 of 8 FAX : 886-3-328-4978 Issued Date : Sep. 11, 2019 Form version: 180516
