Raspberry Pi Trading 30 Station Road Cambridge CB1 2JH UK Raspberry Pi Web Trading Ltd http://raspberrypi.org RF Exposure Considerations for the Raspberry Pi (Trading) Ltd Single Board Computer FCC ID: 2ABCB-RPI0W The FCC requires that the calculated MPE for mobile equipment to be equal to or less than a given limit dependent on frequency at a distance of 20 cm from a device to the body of a user. The transmitters in the Raspberry Pi single board computer cover the frequency bands 2402 to 2480 for BT and 2412 -2462MHz for WLAN operation. Simultaneous transmission is not supported by the Raspberry Pi single board computer. The following FCC Rule Parts and procedures are applicable: Part 1.1310 – Radiofrequency radiation exposure limits Part 2.1091 – Radiofrequency radiation exposure evaluation: mobile devices KDB447498 D01 v06 Mobile and Portable Devices RF Exposure Procedures and Equipment Authorisation Policies MPE calculation S = EIRP/(4 π R2) Where S = Power density EIRP = P x G P = Maximum transmitter power Registered Company Number: 8207441

G = Antenna gain R = distance to the centre of radiation of the antenna For 2.4GHz band: Values S = 1.0 mW/cm2 for General population uncontrolled exposure (FCC Part 1.1310, Table 1(B) Radiofrequency radiation exposure limits) S = 1.0mW/cm2 P = 17.0dBm (50.1mW) {maximum WLAN/ BT power} G = 2.0dBi (x1.58) R = 20cm Calculation: S = PG/4 π R2 S = 50.1 x 1.58/(12.56 x (20)2) S = 79.4/5026 S = 0.0158 mW/cm2 Conclusion This confirms compliance to the required FCC Part 1.1310 Radio frequency radiation exposure limit of 1.0mW/cm2 at 20cm operation and, hence, meets the requirements of FCC rule part 2.1091(c) and KDB447498 D01 v06, section 7.1.
