Maximum Permissible Exposure 3.1 RF Exposure calculation According to the FCC rule 1.1310 table 1B, the limit for the maximum permissible RF exposure for an uncontrolled environment are f/1500 ㎽/㎝² for the frequency range between 300 ㎒ and 1 500 ㎒ and 1.0 ㎽/㎝² for the frequency range between 1 500 ㎒ and 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 Where S = Power density in ㎽/㎝², Z = Impedance of free space, 377 Ω 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 Where d = distance in ㎝, P = Power in ㎽, G = Numeric antenna gain, and S = Power density in ㎽/㎝² 3.2 EUT Descrption Kind of EUT Wireless Home Camera Operating Frequency Band ■ WLAN(802.11b/g/n(HT20)): 2 412 ㎒ ~ 2 462 ㎒ □ WLAN(802.11n(HT40)): 2 422 ㎒ ~ 2 452 ㎒ □ WLAN: 5 180 ㎒ ~ 5 320 ㎒ / 5 500 ㎒ ~ 5 700 ㎒ □ WLAN: 5 745 ㎒ ~ 5 825 ㎒ □ Bluetooth: …
