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: 퐒= 퐏퐆 ퟒ훑퐑 ퟐ Where: S = Power Density P = Output Power at Antenna Terminals G = Gain of Transmit Antenna (linear gain) R = Distance from Transmitting Antenna 4. Radio Frequency Radiation Exposure Evaluation Band Antenna Gain (dBi) Maximum Power (dBm) Maximum EIRP (dBm) Maximum PG (mW) Power Density at 20cm (mW/cm^2) Limit (mW/cm^2) Z-Wave -2.39 17.95 15.56 35.97 0.007 0.608 Conclusion: According to 47 CFR §2.1091, the RF exposure analysis concludes that the RF Exposure is FCC compliant.
