PREPARED BY : , DATE: Jan. 14, 2013 ( Lori Chung, Specialist ) APPROVED BY : , DATE: Jan. 14, 2013 ( May Chen, Manager ) Report No.: SA130402E05 5 of 6 Report Format Version 5.0.0 2. RF EXPOSURE LIMIT LIMITS FOR MAXIMUM PERMISSIBLE EXPOSURE (MPE) FREQUENCY RANGE (MHz) ELECTRIC FIELD STRENGTH (V/m) MAGNETIC FIELD STRENGTH (A/m) POWER DENSITY (mW/cm 2 ) AVERAGE TIME (minutes) LIMITS FOR GENERAL POPULATION / UNCONTROLLED EXPOSURE 300-1500 ... ... F/1500 30 1500-100,000 ... ... 1.0 30 F = Frequency in MHz 3. MPE CALCULATION FORMULA Pd = (Pout*G) / (4*pi*r 2 ) where Pd = power density in mW/cm 2 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 4. 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.: SA130402E05 6 of 6 Report Format Version 5.0.0 5. CALCULATION RESULT OF MAXIMUM CONDUCTED POWER FREQUENCY (MHz) MAX POWER (mW) ANTENNA GAIN (dBi) DISTANCE (cm) POWER DENSITY (mW/ cm 2 ) LIMIT (mW/cm 2 ) 2412-2462 188.799 0.29 20 0.04015 1 --- END --- CONCLUSION: Both of the 2.4GHz and 5GHz WLAN can transmit simultaneously, the formula of calculated the MPE is: CPD 1 / LPD 1 + CPD 2 / LPD 2 + ......etc. < 1 CPD = Calculation power density LPD = Limit of power density Therefore, the worst-case situation is 0.12256 / 1 + 0.42671 / 1 = 0.549, which is less than “1”. This confirmed that the device comply with FCC 1.1310 MPE limit.
