REPORT NO: 09U12689-7 DATE: OCTOBER 26, 2009 FCC ID: J9C-EA544D2 IC: 2723A-EA544D2 11. 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: 09U12689-7 DATE: OCTOBER 26, 2009 FCC ID: J9C-EA544D2 IC: 2723A-EA544D2 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 From IC Safety Code 6, Section 2.2 Table 5 Column 4, S = 10 W/m^2 Page 290 of 295 COMPLIANCE CERTIFICATION SERVICES FORM NO: CCSUP4701C 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 CCS.
