Report No.: FR511645 FCC ID: FDI000000028 Page No. : C1 of C3 Appendix C. Maximum Permissible Exposure Report No.: FR511645 FCC ID: FDI000000028 Page No. : C2 of C3 1. Maximum Permissible Exposure 1.1. Applicable Standard Systems operating under the provisions of this section shall be operated in a manner that ensures that the public is not exposed to radio frequency energy levels in excess limit for maximum permissible exposure. In accordance with 47 CFR FCC Part 2 Subpart J, section 2.1091 this device has been defined as a mobile device whereby a distance of 0.2 m normally can be maintained between the user and the device. (A) Limits for Occupational / Controlled Exposure Frequency Range (MHz) Electric Field Strength (E) (V/m) Magnetic Field Strength (H) (A/m) Power Density (S) (mW/ cm²) Averaging Time |E|²,|H|² or S (minutes) 0.3-3.0 614 1.63 (100)* 6 3.0-30 1842 / f 4.89 / f (900 / f)* 6 30-300 61.4 0.163 1.0 6 300-1500 F/300 6 1500-100,000 5 6 (B) Limits for General Population / Uncontrolled Exposure Frequency Range (MHz) Electric Field Strength (E) (V/m) Magnetic Field Strength (H) (A/m) Power Density (S) (mW/ cm²) Averaging Time |E|²,|H|² or S (minutes) 0.3-1.34 614 1.63 (100)* 30 1.34-30 824/f 2.19/f (180/f)* 30 30-300 27.5 0.073 0.2 30 300-1500 F/1500 30 1500-100,000 1.0 30 Note: f = frequency in MHz ; *Plane-wave equivalent power density 1.2. MPE Calculation Method E (V/m) ＝ d GP30 Power Density: Pd (W/m²) ＝ 377 2 E E ＝ Electric field (V/m) P ＝ Average RF output power (W) G ＝ EUT Antenna numeric gain (numeric) d ＝ Separation distance between radiator and human body (m) The formula can be changed to Pd ＝ 2 377 30 d GP   From the EUT RF output power, the minimum mobile separation distance, d=0.2m, as well as the gain of the used antenna, the RF power density can be obtained. Report No.: FR511645 FCC ID: FDI000000028 Page No. : C3 of C3 1.3. Calculated Result and Limit Exposure Environment: General Population / Uncontrolled Exposure For 5GHz Band (NII): Antenna Type : PCB Antenna Conducted Power for IEEE 802.11a : 25.38dBm Average Output Power Distance (m) Antenna Gain (dBi) Antenna Gain (numeric) (dBm) (mW) Power Density (S) (mW/cm²) Limit of Power Density (S) (mW/cm²) Test Result 0.2 3.90 2.4547 25.3775 344.9444 0.168539 1 Complies For 2.4GHz Band: Antenna Type : PCB Antenna Conducted Power for IEEE 802.11b: 29.05 dBm Average Output Power Distance (m) Antenna Gain (dBi) Antenna Gain (numeric) (dBm) (mW) Power Density (S) (mW/cm²) Limit of Power Density (S) (mW/cm²) Test Result 0.2 2.80 1.9055 29.0534 804.1517 0.304992 1 Complies Conclusion: Both of the WLAN 2.4GHz Band and WLAN 5GHz Band can transmit simultaneously, the formula of calculated the MPE is: CPD1 / LPD1 + CPD2 / LPD2 + ......etc. < 1 CPD = Calculation power density LPD = Limit of power density Therefore, the worst-case situation is 0.304992 / 1 + 0.168539 / 1 = 0.473531, which is less than “1”. This confirmed that the device comply with FCC 1.1310 MPE limit.
