MPE Evaluation FCC Maximum exposure limits from CFR 47, FCC Part 1.1310: Table 1—Limits for Maximum Permissible Exposure (MPE) Frequency range Electric field strength Magnetic field strength Power density Averaging time (MHz) (V/m) (A/m) (mW/cm2) (minutes) (A) Limits for Occupational/Controlled Exposure 0.3-3.0 614 1.63 *100 6 3.0-30 1842/f 4.89/f *900/f 2 6 30-300 61.4 0.163 1.0 6 300-1,500 f/300 6 1,500-100,000 5 6 (B) Limits for General Population/Uncontrolled Exposure 0.3-1.34 614 1.63 *100 30 1.34-30 824/f 2.19/f *180/f2 30 30-300 27.5 0.073 0.2 30 300-1,500 f/1500 30 1,500-100,000 1.0 30 Page 1 of 2

Table 2 – Power Density Calculations, FCC Output power +10% Minimum Antenna Output for Seperation Power Frequency Gain* power tolerance Distance Density Limit MHz dBi mW mW cm mW/cm^2 mW/cm^2 905.6 0 1.76 1.94 20.00 0.00039 0.604 915 0 1.37 1.51 20.00 0.00030 0.610 924.4 0 0.91 1.00 20.00 0.00020 0.616 Note: The user’s manual will stipulate that a 20cm distance from the user is to be maintained. *Antenna gain was set to 0 because power is reported as EIRP and already has antenna gain taken into account The power density is calculated as shown below: S = (P x G)/(4 x π x d^2) – used to calculate exposure at 20 cm d = √(S/(P x G) x 4 X π) – used to calculate minimum distance to meet limits S= power density P = transmitter conducted power (in mW) G = antenna numeric gain D = distance to radiation center (20 cm) Page 2 of 2
