Openpath Security Inc. Electromagnetic Compatibility Model Smart Reader & Mullion Smart Reader MPE Calculation Electromagnetic Compatibility Criteria for Intentional Radiators RF Exposure Purpose: Co-location of two modules, Taiyo Yuden Model EYSGJN (FCC ID: RYYEYSGJN) and Rigado BMD-340 (FCC ID: 2AA9B10). RF Exposure Requirements: §1.1307(b)(1) and §1.1307(b)(2): 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 levels in excess of the Commission’s guidelines. RF Radiation Exposure Limit: §1.1310: As specified in this section, the Maximum Permissible Exposure (MPE) Limit shall be used to evaluate the environmental impact of human exposure to radiofrequency (RF) radiation as specified in Sec. 1.1307(b), except in the case of portable devices which shall be evaluated according to the provisions of Sec. 2.1093 of this chapter. Limits for General Population/Uncontrolled Exposure Frequency range Electric field strength Magnetic field strength Power density Averaging time (MHz) (V/m) (A/m) (mW/cm2) (minutes) 0.3-1.34 614 1.63 *100 30 2 1.34-30 824/f 2.19/f *180/f 30 30-300 27.5 0.073 0.2 30 300-1,500 -- -- f/1500 30 1,500-100,000 -- -- 1.0 30 Limits for Maximum Permissible Exposure (MPE) MET Report: EMCS101883-MPE HF © 2019, Eurofins MET Labs, Inc.
