RF EXPOSURE EVALUATION According to FCC 1.1310: The criteria listed in the following table shall be used to evaluate the environment impact of human exposure to radio frequency(RF) Radiation as specified in KDB 447498 D01 V06 and §1.1307(b) CFR Title 47 §2.1091(b): (b) For purposes of this section, a mobile device is defined as a transmitting device designed to be used in other than fixed locations and to generally be used in such a way that a separation distance of at least 20 centimeters is normally maintained between the transmitter’s radiating structure(s) and the body of the user or nearby persons. FCC ID: 2BBH5-DC24600 EUT Specification EUT DC600 Charger Frequency band (Operating) WLAN: 2.412GHz ~ 2.462GHz WLAN: 5.18GHz ~ 5.24GHz WLAN: 5.745GHz ~ 5.825GHz Others: 2.402GHz~2.480GHz BT NFC: 13.56MHz RFID: 125kHz Device category Portable (<20cm separation) Mobile (>20cm separation) Others ___ Exposure classification Occupational/Controlled exposure (S = 5mW/cm2) General Population/Uncontrolled exposure (S=1mW/cm2) Antenna diversity Single antenna Multiple antennas Tx diversity Rx diversity Tx/Rx diversity Evaluation applied MPE Evaluation SAR Evaluation Limits for Maximum Permissible Exposure(MPE) Note: Emissions between 100 kHz to 300 kHz should be assessed versus the limits at 300 kHz in Table 1 of Section 1.1310: 614 V/m and 1.63 A/m.AKDB inquiry is required to determine the applicable exposure limits below 100 kHz. Friis transmission formula: Pd=(Pout*G)\(4*pi*R2) Where Pd= Power density in mW/cm 2 Pout=output power to antenna in Mw G= gain of antenna in linear scale Pi=3.1416 R= distance between observation point and center of the radiator in cm Pd the limit of MPE, 1mW/cm2. If we know the maximum gain of the antenna and total power input to the antenna, through the calculation, we will know the distance where the MPE limit is reached.
