REPORT NO: 12U14476-1B DATE: AUG 29, 2012 FCC ID: LDKTG2050 IC: 2461B-TG2050 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: 12U14476-1B DATE: AUG 29, 2012 FCC ID: LDKTG2050 IC: 2461B-TG2050 IC RULES IC Safety Code 6, Section 2.2.1 (a) A person other than an RF and microwave exposed worker shall not be exposed to electromagnetic radiation in a frequency band listed in Column 1 of Table 5, if the field strength exceeds the value given in Column 2 or 3 of Table 5, when averaged spatially and over time, or if the power density exceeds the value given in Column 4 of Table 5, when averaged spatially and over time.

REPORT NO: 12U14476-1B DATE: AUG 29, 2012 FCC ID: LDKTG2050 IC: 2461B-TG2050 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 mW/cm^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 RSS-102 Clause 2.5.2 RF exposure evaluation is required if the separation distance between the user and the device’s radiating element is greater than 20 cm, except when the device operates as follows: •below 1.5 GHz and the maximum e.i.r.p. of the device is equal to or less than 2.5 W; •at or above 1.5 GHz and the maximum e.i.r.p. of the device is equal to or less than 5 W.

REPORT NO: 12U14476-1B DATE: AUG 29, 2012 FCC ID: LDKTG2050 IC: 2461B-TG2050 RESULTS Band Mode Separation Output Antenna Duty Source FCC Power IC Power Distance Power Gain Cycle Based Density Density EIRP (cm) (dBm) (dBi) (%) (mW) (mW/cm^2) (W/m^2) 2.4 GHz WLAN 20 17.1 4.0 100 129.1 0.03 0.257 5 GHz WLAN 20 18.4 6.0 100 272.9 0.05 0.543 The device operates above 1.5 GHz with a maximum EIRP less than or equal to 5 Watts as a mobile device with a minimum separation distance of 20 cm, therefore it is exempt from routine RF Exposure Evaluation under RSS-102.
