RF EXPOSURE REPORT REPORT NO.: SA110117E06 MODEL NO.: E2500 FCC ID: Q87-E2500 ACCORDING: FCC Guidelines for Human Exposure IEEE C95.1 APPLICANT: Cisco Consumer Products LLC ADDRESS: 121 Theory Drive Irvine, CA 92617(USA) ISSUED BY: Bureau Veritas Consumer Products Services (H.K.) Ltd., Taoyuan Branch Hsin Chu Laboratory LAB ADDRESS: No. 81-1, Lu Liao Keng, 9th Ling,Wu Lung Tsuen, Chiung Lin Hsiang, Hsin Chu Hsien 307, Taiwan Report No.: SA110117E06 1 Report Format Version 4.0.0

1. RF EXPOSURE LIMIT 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. 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 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.: SA110117E06 2 Report Format Version 4.0.0

4. CALCULATION RESULT OF MAXIMUM CONDUCTED POWER For 15.247(2.4GHz): FREQUENCY ANTENNA POWER MAX POWER DISTANCE LIMIT BAND GAIN DENSITY (dBm) (cm) (mW/cm2) (MHz) (dBi) (mW/ cm2) 2412-2462 26.4 3.5 20 0.195 1.00 For 15.247(5GHz): FREQUENCY ANTENNA POWER MAX POWER DISTANCE LIMIT BAND GAIN DENSITY (dBm) (cm) (mW/cm2) (MHz) (dBi) (mW/ cm2) 5745-5825 25.9 5 20 0.245 1.00 For 15.407(5GHz): FREQUENCY ANTENNA POWER MAX POWER DISTANCE LIMIT BAND GAIN DENSITY (dBm) (cm) (mW/cm2) (MHz) (dBi) (mW/ cm2) 5180-5240 16.5 5 20 0.028 1.00 CONCLUSION: Both of the 2.4GHz and 5GHz can transmit simultaneously, the formula of calculated the MPE is: CPD1 / LPD1 + CPD2 / LPD2 + ……etc. < 1 CPD = Calculation power density LPD = Limit of power density Therefore, the worst-case situation is 0.195 / 1 + 0.245 / 1= 0.44, which is less than “1”. This confirmed that the device comply with FCC 1.1310 MPE limit. --- END --- Report No.: SA110117E06 3 Report Format Version 4.0.0
