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 Friis Formula Friis transmission 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 Pd id the limit of MPE, 1 mW/cm 2 . 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. 1.2. Test Procedure Software provided by client enabled the EUT to transmit and receive data at lowest, middle and highest channel individually. The temperature and related humidity: 18°Cand 78％ RH.

Test Result of RF Exposure Evaluation Product : Polycom Cordless Phone Test Item : RF Exposure Evaluation Test Site : No.3 OATS Antenna Gain Antenna Gain: The maximum Gain measured in fully anechoic chamber is 2dBi in linear scale. Output Power Into Antenna & RF Exposure Evaluation Distance (2dBi): Channel Frequency (MHz) Output Power to Antenna (mW) Power Density at R = 1.0 cm (mW/cm2) 2 2405.00 1.4093 0.1777 20 2441.00 1.0814 0.1364 39 2479.00 0.6871 0.0867 The distance r (4 th column) calculated from the Fries transmission formula is far shorter than 1.0 cm separation requirement.
