        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

Remark:
1. Output power including tune up tolerance;
2. ∑(Power Density / Limit): This is a summation of [(power density for each transmitter/antenna include in the simultan
   eous transmission)/(corresponding MPE limit )], for LoRa + Bluetooth.
3. Considering the LoRa /Bluetooth 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

              7. Conclusion
                The measurement results comply with the FCC Limit per 47 CFR 2.1091 and RSS-102 Issue 5 for the
                uncontrolled RF Exposure.
