For Scope 2, Based on the conducted test point from module, the new ANT Matching will not impact the conducted test result, so there is only retest for Radiates Spurious Emission on DTS, DSS, UNII-1: 5150 MHz ~ 5250 MHz, UNII-2A: 5250 MHz ~ 5350 MHz, UNII-2C: 5470 MHz ~

5725 MHz, UNII-3: 5725 MHz ~ 5850 MHz, refer to the retest result, those modifications in the equipment which do not degrade the characteristics, so C1PC has been used for modification, for the test items, please refer to the original test report. Please kindly review the application documents submitted and grant approval for this Permissive Change application. Sincerely yours, ________________________
