Report No. 1970268R-RF-US-Exp 1. RF Exposure Evaluation 1.1. 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 Electric Field Magnetic Field Power Density Average Time (MHz) Strength (V/m) Strength (A/m) (mW/cm2) (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 According to IC RSS-102 Issue 5: For the purpose of this standard, Industry Canada has adopted the SAR and RF field strength limits established in Health Canada’s RF exposure guideline.

Friis Formula Friis transmission 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 id the limit of MPE, 1 mW/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. 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℃and 78％ RH.
