REQUIREMENTS - LIMITATION OF EXPOSURE 6.1. LIMITS 6.1.1. 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. 6.1.2. LIMITS APPLICABLE TO THE EUT For mobile radio equipment operating in the cellular phone band, the lowest power density limit is calculated using the lowest frequency, as 824 MHz / 1500 = 0.55 mW/cm^2 . For operation in the PCS band, the 2.4 GHz band and the 5 GHz bands, from FCC §1.1310 Table 1 (B), the maximum value of S = 1.0 mW/cm^2.

REPORT NO: 12U14542-3A DATE: NOVEMBER 12, 2012 EUT: UMTS (850/1900)/ (E) GPRS (850/1900) w/ 1TX ANT + MODEL: AC340U LTE (B2/4/5/17,1TX ANT) USB MODEM FCC ID: N7NAC340U 6.2. 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 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 Where applicable (for example, multi-slot cell phone applications) a duty cycle factor may be applied. Source-based time-averaged EIRP = (DC / 100) * EIRP where DC = Duty Cycle in %, as applicable EIRP = Equivalent Isotropic Radiated Power in W For multiple chain devices, and colocated transmitters operating simultaneously in frequency bands where the limit is identical, the total power density is calculated using the total EIRP obtained by summing the Power * Gain product (in linear units) of each transmitter. Total EIRP = (P1 * G1) + (P2 * G2) + ... + (Pn * Pn) where Px = Power of transmitter x Gx = Numeric gain of antenna x For multiple colocated transmitters operating simultaneously in frequency bands where different limits apply, either the lowest limit applicable to the co-located transmitters can be applied or a fraction of the exposure limit is established for each band, such that the sum of the fractions is less than or equal to one. 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.
