Part 2, Subpart J, Section 2.1091 Maximum Permissible Exposure Calculations For Mult-Voice Radio MV-ONE EUT Device Category = General Population/Uncontrolled Exposure EUT consists of one ISM band radio transmitting operating over a range of 902.6 MHz to 926.6 MHz and one transceiver operating over a range of 2402 MHz to 2480 MHz MPE Summary: See pages 2 for explanation of Antenna Gain and distance KDB 447498 D01 General RF Exposure Guidance v06 gives the 1-g and 10-g SAR test exclusion thresholds. The limits for 100 MHz to 6 GHz and a test separation distance of ≤50 mm are defined by the following equations: ((max EIRP, mW / (minimum separation, mm) * √F GHz ≤3.0 for 1-g SAR or ≤7.5 for 10-g SAR EIRP calculations for the 902.8 MHz to 926.6 MHz transmitter are shown below: Frequency Max power to antenna Antenna Gain EIRP EIRP (MHz) (dBm) (dBi) (dBm) mW 902.8 28.17 -10 18.17 65.615 914.4 28.33 -10 18.33 68.077 926.6 28.36 -10 18.36 68.549 MPE and Limit for the 902.8 MHz to 926.6 MHz transmitter are calculated as follows: EIRP Separation Frequency Full Exposure Maximum Duty Cycle Worst-case Exposure Limit Result (mW) (mm) (GHz) (mW/mm) (%) (mW/mm) 1-g 65.615 25 0.9028 2.476 12.5 0.310 3.0 Exempt 68.077 25 0.9144 2.604 12.5 0.326 3.0 Exempt 68.549 25 0.9266 2.639 12.5 0.330 3.0 Exempt MPE and Limit for the 2402 MHz to 2480 MHz transceiver are calculated as follows: EIRP Separation Frequency Full Exposure Maximum Duty Cycle Worst-case Exposure Limit Result (mW) (mm) (GHz) (mW/mm) (%) (mW/mm) 1-g 0.03 25 2.402 0.002 100 0.002 3.0 Exempt 0.02 25 2.441 0.001 100 0.001 3.0 Exempt 0.01 25 2.480 0.001 100 0.001 3.0 Exempt Adding the maximum worst-case exposure for each transmitter from the tables above (0.33 + 0.002 = 0.332), the total exposure from the device is less than the specified 1-g threshold of 3.0. Result: The device meets FCC MPE limit for General Population/Uncontrolled Exposure ALZMV2_MPE.docx Page 2 of 2 PROPRIETARY The antenna was designed to have a minimum attenuation of 10db towards the head. Thus having an effective radiated power of 18.36 dBM. See antenna design pattern below: The antenna separation is diagrammed below:
