FCC RF EXPOSURE REPORT FCC ID: RRK-WMCAC15 Project No. : 1805H003A Equipment : Wifi Card Test Model : WMC-AC15 Series Model : N/A Applicant : Alpha Address No. 8, Li-shing 7th Road, Science-based Industrial Park, : Hsinchu, Taiwan, R.O.C. According: :FCC Guidelines for Human Exposure IEEE C95.1 & FCC Part 2.1091 BTL INC. No. 29, Jintang Road, Tangzhen Industry Park, Pudong New Area, Shanghai 201210,China TEL: +86-021-61765666 Report No.: BTL-FCCP-5-1805H003A Page 1 of 4

1. CERTIFICATION Equipment : Wifi Card Brand Name : Alpha Test Model : WMC-AC15 Series Model : N/A Applicant : Alpha Date of Test : Oct. 19, 2018~Oct. 31, 2018 Test Sample : Engineering Sample No.: B180800106 Standards : FCC Title 47 Part 2.1091, OET Bulletin 65 Supplement C The above equipment has been tested and found compliance with the requirement of the relative standards by BTL Inc. The test data, data evaluation, and equipment configuration contained in our test report (Ref No. BTL-FCCP-5-1805H003A) were obtained utilizing the test procedures, test instruments, test sites that has been accredited by the Authority of A2LA according to the ISO/IEC 17025 quality assessment standard and technical standard(s). Report No.: BTL-FCCP-5-1805H003A Page 2 of 4

2. MPE CALCULATION METHOD Calculation Method of RF Safety Distance: where: S = power density P = power input to the antenna G = power gain of the antenna in the direction of interest relative to an isotropic radiator R = distance to the center of radiation of the antenna Table for Filed Antenna: For 2.4G Gain Ant. Brand Model Name Antenna Type Connector Note (dBi) CIU ANTENNE 1 296242441 PCB N/A 0 N/A WIFI DUAL A01 CIU ANTENNE 2 296242441 PCB N/A 0 N/A WIFI DUAL A01 Note: This EUT supports MIMO 2X2, any transmit signals are correlated with each other, so Directional gain = GANT+10log(N)dBi, that is Directional gain=0+10log(2)dBi=3.01 For 5G Antenna Gain Ant. Manufacturer Model Name Connector Note Type (dBi) CIU ANTENNE 1 296242441 PCB N/A -2 N/A WIFI DUAL A01 CIU ANTENNE 2 296242441 PCB N/A -2 N/A WIFI DUAL A01 Note: (1) This EUT supports MIMO 2X2, any transmit signals are correlated with each other and the Beamforming Gain is 3.0dBi,so Directional gain = 3+(-2)=1.
