RF Exposure Evaluation for FCC MPE Calculation The power Density ( mW / CM 2 ) is calculated as follows: PG S= 4±R 2 S=power density ( mW / CM 2 ) P=power input to the antenna (mW) G=power input to the antenna in the direction of interest relative to an isotropic radiator R=distance to the center of radiation of the antenna (CM) FCC MPE, BLE standalone operation Transmit Power Density Radio Antenna Distance Power Density Result Frequency limit Power Gain ˄CM˅ ˄ mW / CM 2 ˅ (MHz) ˄ mW / CM 2 ˅ ˄dBm˅ ˄dBi˅ 2402 1.0 1.75 0 20 0.0003 0.0003 < 1 Conclusion: Compliance with FCC’s RF Exposure.

FCC MPE, BLE & LoRa simultaneous operation According to 865664D02 2.2 d) 1): The sum of the ratios of the spatially averaged results to the applicable frequency dependent MPE limits: Simultaneous Transmission mode The sum of the ratios Result BLE + LoRa DTS 0.0003/1 +0.008/0.61 =0.0134 < 1 Conclusion: Compliance with FCC’s RF Exposure. 3. RF Exposure Evaluation for IC EUT RF Exposure Evaluation standalone operation Exemption Limits for Routine Evaluation – RF Exposure Evaluation RF exposure evaluation is required if the separation distance between the user and/or bystander and the device’s radiating element is greater than 20 cm, except when the device operates as follows: At or above 300 MHz and below 6 GHz and the source-based, time-averaged maximum E.I.R.P. of the device is equal to or less than 1.31 x 10-2 ƒ0.6834 W (adjusted for tune-up tolerance), where ƒ is in MHz; RF exposure evaluation exempted power for BLE: 2.73W RF exposure evaluation exempted power for LoRa DTS: 1.38W The max E.I.R.P. for BLE: 1.75dBm = 0.001496W The max E.I.R.P. for LoRa DTS: 15.99dBm = 0.03971W All E.I.R.P. are less than RF exposure evaluation exempted power. So RF exposure evaluation is not required. EUT RF Exposure Evaluation simultaneous operation The sum of the ratios of the spatially averaged results to the applicable frequency dependent MPE limits: Simultaneous Transmission mode The sum of the ratios Result BLE + LoRa DTS 0.001496/2.73 +0.03971/1.38 =0.0293 < 1 Conclusion: Compliance with IC’s RF Exposure.
