REPORT NO: 11U13729-1 DATE: APRIL 14, 2011 EUT: CDMA+ WIMAX + WIFI MOBILE HOT SPOT FCC ID: N7N-MHS802 8. MAXIMUM PERMISSIBLE EXPOSURE FCC RULES §1.1310 The criteria listed in Table 1 shall be used to evaluate the environmental impact of human exposure to radio-frequency (RF) radiation as specified in §1.1307(b), except in the case of portable devices which shall be evaluated according to the provisions of §2.1093 of this chapter.

REPORT NO: 11U13729-1 DATE: APRIL 14, 2011 EUT: CDMA+ WIMAX + WIFI MOBILE HOT SPOT FCC ID: N7N-MHS802 EQUATIONS Power density is given by: S = EIRP / (4 * Pi * D^2) where S = Power density in W/m^2 EIRP = Equivalent Isotropic Radiated Power in W D = Separation distance in m Power density in units of W/m^2 is converted to units of mWc/m^2 by dividing by 10. Distance is given by: D = SQRT (EIRP / (4 * Pi * S)) where D = Separation distance in m EIRP = Equivalent Isotropic Radiated Power in W S = Power density in W/m^2 In the table(s) below, Power and Gain are entered in units of dBm and dBi respectively and conversions to linear forms are used for the calculations. LIMITS From FCC §1.1310 Table 1 (B), the maximum value of S = 1.0 mW/cm^2 RESULTS Mode Separation Output Power Antenna FCC Power Bandwidth Distance Gain Density Modulation (m) (dBm) (dBi) (mW/cm^2) 5MHz QPSK WiMAX 0.20 25.58 6.00 0.286 5MHz 16QAM WiMAX 0.20 25.62 6.00 0.289 10MHz QPSK WiMAX 0.20 25.45 6.00 0.278 10MHz 16QAM WiMAX 0.20 25.26 6.00 0.266 Page 18 of 20 COMPLIANCE CERTIFICATION SERVICES (UL CCS) FORM NO: CCSUP4031B 47173 BENICIA STREET, FREMONT, CA 94538, USA TEL: (510) 771-1000 FAX: (510) 661-0888 This report shall not be reproduced except in full, without the written approval of UL CCS.
