MPE Calculations (Mobile) The device is not a portable device (i.e. intended to be worn on the body or be hand-held), so it is classified as being either a mobile device or a fixed mounted device. The user’s manual specifies a minimum separation distance of at least 20cm, consistent with this classification. FCC part 1.1310, Table 1 limits the power density for uncontrolled exposure. The power density, Pd (mW/cm2 ) calculated from the maximum EIRP, Pt (mW) and the distance, d (m), between the transmitting antenna and the closest person, can be calculated using: Formula is: Pd = Pt / (4*pi*d2) MPE Limit Pd at 20cm Distance where Pd Frequency (MHz) EIRP (mW) (mW/cm2) (mW/cm2) = Limit (cm) 2400 - 2480 1 1.00 0.000 0.3 824 0.5493333 1000.00 0.199 12.0 1850 -1910 1 1166.81 0.232 9.6 Total EIRP Power from all radios: 2167.81 mW Total PSD at 20 cm from all radios: 0.431 mW/cm^2 Worst Case MPE limit: 0.549 mW/cm^2 Refer to Conclusion statement for explation Output Power (dBm) Antenna gain EIRP Total EIRP Band Mode Channels Available Channels Used Peak Average (Max) dBm W W dBm 2400 - 2483.5 - - 0.0 0.0 0.0 0.001 79 1 0.001 0.00 824 - 849 - - 30.0 0.0 30.0 1.000 125 1 1.000 30.00 1850 - 1910 - - 30.7 0.0 30.7 1.167 300 1 1.167 30.67 Totals: 3 2.168 33.36 MPE exposure is based on one 2.4GHz pre-approved modules with one 800/1900 MHz transmitter. Device can be programmed to transmitt simultaneously. Conclusion: Total combined power from all radios is 2.167.81 Watts this calculates into a total exposure of .447 mW/cm^2 at 20 cm. Using the worse case limit of 824 MHz/1500 = .549mW/cm^2 this shows that the co-located transmitters will be in compliance to the MPE limits when in simultaneous transmission.
