1. CERTIFICATION PRODUCT: Wireless smart hub MODEL: DCH-G021 BRAND: D-Link APPLICANT: D-LINK CORPORATION TESTED: Oct. 29 ~ Nov. 03, 2014 TEST SAMPLE: ENGINEERING SAMPLE STANDARDS: FCC Part 2 (Section 2.1091) KDB 447498 D03 IEEE C95.1 The above equipment (Model: DCH-G021) has been tested by Bureau Veritas Consumer Products Services (H.K.) Ltd., Taoyuan Branch, and found compliance with the requirement of the above standards. The test record, data evaluation & Equipment Under Test (EUT) configurations represented herein are true and accurate accounts of the measurements of the sample’s EMC characteristics under the conditions specified in this report. PREPARED BY : , DATE: Nov. 04, 2014 Polly Chien / Specialist APPROVED BY : , DATE: Nov. 04, 2014 Ken Liu / Senior Manager NOTE: This is a duplicate report of SA140729C08. The difference compared with the original report is adding one adapter. Due to no effect on any test item and we didn’t re-test.

2. RF EXPOSURE 2.1 LIMITS FOR MAXIMUM PERMISSIBLE EXPOSURE (MPE) FREQUENCY ELECTRIC FIELD MAGNETIC FIELD POWER DENSITY AVERAGE TIME RANGE (MHz) STRENGTH (V/m) STRENGTH (A/m) (mW/cm2) (minutes) LIMITS FOR GENERAL POPULATION / UNCONTROLLED EXPOSURE 300-1500 … … F/1500 30 1500-100,000 … … 1.0 30 F = Frequency in MHz 2.2 MPE CALCULATION FORMULA Pd = (Pout*G) / (4*pi*r2) where Pd = power density in mW/cm2 Pout = output power to antenna in mW G = gain of antenna in linear scale Pi = 3.1416 R = distance between observation point and center of the radiator in cm 2.3 CLASSIFICATION The antenna of this product, under normal use condition, is at least 20cm away from the body of the user. So, this device is classified as Mobile Device. Report No.: SA140729C08A 5 of 6 Report Format Version 5.0.1 Reference No.: 141024C19

2.4 CALCULATION RESULT OF MAXIMUM CONDUCTED POWER Conducted Conducted Antenna Power Frequency Limit Mode power power Gain Density band (MHz) (mW/cm2) (mW) (dBm) (dBi) (mW/cm2) WiFi 2.4G 2412~2462 274.157 24.38 2.10 0.088 1 BT EDR 2402~2480 9.016 9.55 2.10 0.003 1 Zigbee 2405 ~ 2480 79.433 19.00 1.72 0.023 1 **Zigbee can transmit simultaneously with WLAN or BT but not WLAN and BT. WLAN and BT cannot transmit at the same time. CONCULSION: Zigbee can transmit simultaneously with WLAN or BT, the formula of the calculated MPE is: CPD1 / LPD1 + CPD2 / LPD2 + ……etc. < 1 CPD = Calculation power density LPD = Limit of power density Conducted power: WiFi 2.4G + Zigbee = 274.157 + 79.433 = 353.59(mW)= 25.48(dBm) < 30(dBm) BT EDR + Zigbee = 9.016 + 79.433 = 88.449(mW)= 19.47(dBm) < 30(dBm) Power density: WiFi 2.4G + Zigbee = 0.088 + 0.023 = 0.111 BT EDR + Zigbee = 0.003 + 0.023 = 0.026 Therefore the maximum calculations of the above situations are less than the “1” limit. --- END --- Report No.: SA140729C08A 6 of 6 Report Format Version 5.0.1 Reference No.: 141024C19
