Test report no.: 1-4810/17-01-02 Prediction of MPE limit at given distance - FCC Equation from page 18 of OET Bulletin 65, Edition 97-01 S = PG / 4π R2 where: S = Power density P = Power input to the antenna G = Antenna gain R = Distance to the center of radiation of the antenna PG = EIRP The table below is excerpted from Table 1B of 47 CFR 1.1310 titled “Limits for Maximum Permissible Exposure (MPE), Limits for General Population/Uncontrolled Exposure” Frequency Range (MHz) Power Density (mW/cm2) Averaging Time (minutes) 300 -1500 f/1500 30 1500 - 100000 1.0 30 where f = Frequency (MHz) Prediction: worst case Maximum field strength (worst case = pos-peak) E 111.4 dBµV/m @3m see test report 1-4810/17-01-02-A P Max power input to the antenna -/- dBm G Antenna gain -/- dBi PG EIRP 16.1 dBm / 41.1 mW R Distance 20 cm S MPE limit for uncontrolled exposure 1 mW/cm2 Calculated Power Density 0.0082 mW/cm2 with EIRP [dBm] = E [dBμV/m] + 20lg(d [m]) - 104.8 Conclusion: The power density levels for FCC at a distance of ≤20 cm are below the maximum levels allowed by regulations.

Test report no.: 1-4810/17-01-02 Prediction of MPE limit at given distance - IC RSS-102, Issue 5, 2.5.2 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: • below 20 MHz and the source-based, time-averaged maximum e.i.r.p. of the device is equal to or less than 1 W (adjusted for tune-up tolerance); • at or above 20 MHz and below 48 MHz and the source-based, time-averaged maximum e.i.r.p. of the device is equal to or less than 4.49/ƒ0.5W (adjusted for tune-up tolerance), where ƒ is in MHz; • at or above 48 MHz and below 300 MHz and the source-based, time-averaged maximum e.i.r.p. of the device is equal to or less than 0.6 W (adjusted for tune-up tolerance); • 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; • at or above 6 GHz and the source-based, time-averaged maximum e.i.r.p. of the device is equal to or less than 5 W (adjusted for tune-up tolerance). Prediction: worst case Maximum field strength (worst case = pos-peak) E 111.4 dBµV/m @3m see test report 1-4810/17-01-02-A P Max power input to the antenna -/- dBm G Antenna gain -/- dBi PG EIRP 16.1 dBm / 41.1 mW R Distance 20 cm S MPE limit for uncontrolled exposure 1 mW/cm2 Calculated Power Density 0.0082 mW/cm2 with EIRP [dBm] = E [dBμV/m] + 20lg(d [m]) - 104.8 Conclusion: For applications where minimum distance to radiating element is ≤20cm, Annex C of RSS-102 should be filled out.
