RF Exposure Evaluation Report Report No. : FA720930 4. 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: �� = �� � Where: S = Power Density P = Output Power at Antenna Terminals G = Gain of Transmit Antenna (linear gain) R = Distance from Transmitting Antenna SPORTON INTERNATIONAL INC.

The WWAN operation is also into this host, and collocated power density calculation in above table, for the power density of WWAN detail information please refer to original report (FCC ID : SRQ—ZM8620). 2.X (Power Density / Limit): This is a summation of [{power density for each transmitter/antenna included in the simultaneous transmission)/ (corresponding MPE limit)], for WWAN + WLAN. 3. Considering the WWAN module collocation with the WLAN transmitter of the EIRP performance listed in the table above, the aggregated (power density /limit) is smaller than 1, and MPE of 2 collocated transmitters is compliant Conclusion: According to 47 CFR §2.1091, the RF exposure analysis concludes that the RF Exposure is FCC compliant.
