Maximum Permissible Exposure 3.1 RF Exposure calculation According to the FCC rule §1.1310 the limit for General Population/Uncontrolled exposure is 1 ㎽/㎠ for the device operating 1 500 ㎒ ~ 100 000 ㎒. The electric field generated for a 1 ㎽/㎝² exposure is calculated as follows: E = √ (30 * P * G) / D, and S = E² / Z = E² / 377, because 1 ㎽/㎝² = 10 W/m² S = Power density in ㎽/㎝², Z = Impedance of free space, 377 Ω P = Power input to the external antenna (Output power from the EUT antenna port (㏈m) – cable loss (㏈)), E = Electric filed strength in V/m, G = Numeric antenna gain, and D = distance in meter Combing equations and rearranging the terms to express the distance as a function of the remaining variable D = √ (30 * P * G) / (377 *10 S) Changing to units of ㎽ and cm, using P (㎽) = P (W) / 1 000, d (㎝) = 0.01 * d (m) D = 0.282 * √ (P * G) / S 페이지(page) : ( 6 )/( 총(Total) 6 ) ICRT-QPA-17-03 Rev.2 Report No. ICRT-TR-E231002-0A 3.2 Result According to above equation, the following result was obtained.
