Report no.: 1-6027/18-02-09 EUT technologies: Technologies: Max. power (AVG): Max. antenna gain: Min. pathloss: 76 GHz Radar Measured max. EIRP: 22.8dB* n/a -- (if applicable) )* detailed measurement results in CTC advanced test report 1-6027/18-01-07 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 = Output Power including antenna gain 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 Technology RADAR Frequency 76000 MHz P∙G Measured max. EIRP (avg.) 22.8 dBm R Distance 20 cm S MPE limit for uncontrolled exposure 1.0000 mW/cm2 Calculated Power density: 0.0379 mW/cm² Calculated percentage of limit: 3.79% This prediction demonstrates the following: The power density levels for FCC at a distance of 20 cm are below the maximum levels allowed by regulations. © CTC advanced GmbH Page 2 of 3

Report no.: 1-6027/18-02-09 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 76 GHz Technology RADAR Frequency 76000 MHz P∙G Max. measured EIRP (avg.) 22.8 dBm R Distance 20 cm Maximum EIRP 190.5 mW Exclusion Limit from above: 5.00 W Calculated percentage of limit: 3.81% Conclusion: RF exposure evaluation is not required. For applications where minimum distance to radiating element is 20cm Annex C of RSS-102 should be filled out. © CTC advanced GmbH Page 3 of 3
