WORST CASE SELECTION Frequency Range 0 kHz - 1GHz 1GHz - 30GHz Worst Case Antenna Peak Gain in range 84671653 Y2xx 84881230 MiniMega NA 4.26 dBi 6.19 dBi 84671653 Y2xx in 715MHz and 829 MHz. 84728097 Sharkfin ChopTop has slightly higher gain than the Y2xx in 829 MHz but overall gain is lower than Y2xx. Actual testing was performed with the Y2xx antenna but for ERP and MPE calculations, antenna gain 3.81 dBi shall be used as worst case. 84881230 MiniMega NA is the worst case for all frequencies above 1GHz. According to the KDB 178919 and KDB 996369, host manufacturer can use antenna including cable loss has gain less than following table. GSM 850, WCDMA 5, LTE 5 WCDMA 4, LTE 4 GSM 1900, WCDMA 2, LTE 2 LTE 12, LTE 13 3.81 dBi 6.19 dBi 5.33 dBi 4.26 dBi C. POWER REDUCTION To comply the ERP/EIRP limits and meet ERP thresholds for exemption from routine evaluation for MPE, power reduction mechanism is implemented on the module. Depending on the antenna selected for a specific vehicle installation the vehicle manufacturer can select a power of 1 dB in GSM 850, 3.5 dB in GSM 1900 as shown in the tables below. The end user cannot access the controls to reset the output power to the nominal settings to override the power reduction. EUT will be installed under the hood and users cannot reach the EUT itself. All the antennas shall be installed 20cm from any passengers or people around vehicle. Following table shows ERP/EIRP Calculation based on maximum production power. Note 1: Power reduction required for GSM 850 whenever the antenna gain exceed 2.81dBi for the 850 band. Max Tune-up Tolerance Final Gain Incl.

Calculated ERP: Target Power + Tune-up Tolerance + Peak Gain - 2.15 dB Calculated EIRP: Target Power + Tune-up Tolerance + Peak Gain Final ERP/EIRP: ERP/EIRP - Power Reduction GSM 900 is not included in FCC/ISED certified scope but power reduction will be applied for Brazilian market. D. ERP/EIRP MEASUREMENT ERP/EIRP measurements were performed with the highest gain antenna configuration. GSM 850 was measured with Y2xx antenna which has antenna gain 3.66 dBi. Power reduction factor was applied, all the measured values comply under the ERP/EIRP limit. As GEN11NAN is a modular, test was performed in stand-alone configuration and both models were tested with production sample. Frequency
