SAR Evaluation 2.1 RF Exposure Compliance Requirement 2.1.1 Standard Requirement According to §1.1307(e)(1), systems operating under the provisions of this section shall be operated in a manner that ensures that the public is not exposed to radio frequency energy level in excess of the Commission’s guidelines. According to §1.1310 and §2.1091 RF exposure is calculated. KDB447498 D01: Mobile and Portable Devices RF Exposure Procedures and Equipment Authorization Policies 2.1.2 Limits F= Frequency in MHz Friis Formula Friis transmission formula: Pd = (Pout*G)/(4* Pi * R 2) 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.
