RF Exposure Evaluation 2.1. Limits According to FCC 1.1310: The criteria listed in the following table shall be used to evaluate the environment impact of human exposure to radio frequency (RF) radiation as specified in 1.1307(b) 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) (A) Limits for Occupational/ Control Exposures 300-1500 -- -- f/300 6 1500-100,000 -- -- 5 6 (B) Limits for General Population/ Uncontrolled Exposures 300-1500 -- -- f/1500 6 1500-100,000 -- -- 1 30 f= Frequency in MHz 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 Pd is the limit of MPE, 1mW/cm². If we know the maximum gain of the antenna and the total power input to the antenna, through the calculation, we will know the distance r where the MPE limit is reached. Report No.: 1411RSU03606 FCC ID: YZZGXV3240D Page Number: 5 of 5 2.2. Test Result of RF Exposure Evaluation Product IP Multimedia Phone Test Item RF Exposure Evaluation Antenna Gain: The maximum Gain measured in fully anechoic chamber is 2.0dBi for 2.4GHz, 2.0dBi for 5.5GHz in logarithm scale. Test Mode Frequency Band (MHz) Maximum Average Output Power (dBm) Power Density at R = 20 cm (mW/cm 2 ) Limit (mW/cm 2 ) FHSS 2402 ~ 2480 -0.15 0.0003 1 802.11b/g/n-HT20 2412 ~ 2462 16.83 0.0152 1 802.11a/n-HT20 5180 ~ 5240, 5500 ~ 5700, 5745 ~ 5825 14.64 0.0092 1 CONCULISON: Both of the WLAN and Bluetooth can transmit simultaneously. Therefore, the Max Power Density at R (20 cm) = 0.0003mW/cm 2 + 0.0152mW/cm 2 = 0.0155mW/cm 2 < 1mW/cm 2 . So the EUT complies with the requirement. The End
