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 userís 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/cm 2) (mW/cm 2) = Limit (cm) 2400 - 4990 1 1406.52 0.28 10.6 Output Power Antenna gain EIRP Total EIRP Band Mode Channels Available Channels Used Peak Average (Max) dBm W W dBm 2400 - 2483.5 CCK - 20.0 7.5 27.5 0.562 11 1 0.562 27.50 2400 - 2483.5 CCK - 20.0 7.5 27.5 0.562 11 1 0.562 27.50 4940 - 4990 OFDM - 17.0 7.5 24.5 0.282 10 1 0.282 24.50 Totals: 3 1.407 31.48 MPE exposure is based on two 2.4GHz pre-approved modules with one 4.9GHz transmitter.

MPE Calculations (Fixed Location) 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 a fixed mounted device. The userís manual specifies a minimum separation distance of at least 35cm, 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 - 4990 1 11333.35 2.25 30.0 Output Power Antenna gain EIRP Total EIRP Band Mode Channels Available Channels Used Peak Average (Max) dBm W W dBm 2400 - 2483.5 CCK - 13.0 21.0 34.0 2.512 11 1 2.512 34.00 2400 - 2483.5 CCK - 13.0 21.0 34.0 2.512 11 1 2.512 34.00 4940 - 4990 OFDM - 17.0 21.0 38.0 6.310 10 1 6.310 38.00 Totals: 3 11.333 40.54 MPE exposure is based on two 2.4GHz pre-approved modules with one 4.9GHz transmitter.
