Page 1 of 2 RF Exposure and Transmitter Power Considerations for DT-RFIO-Module (US) FCC ID: 2ATFX-101941 The FCC requires that the calculated MPE 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 Cloud Connector US equipment operates in the 902 MHZ – 928 MHz band. 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 MPE CALCULATIONS The MPE calculation used to calculate the safe operating distance for the user is: S = EIRP/4 π R​ 2 WhereS = Power density EIRP = Effective Isotropic Radiated Power (EIRP = P x G) P = Conducted Transmitter Power G = Antenna Gain (relative to an isotropic radiator) R = distance to the centre of radiation of the antenna (safe operating distance) Values: Transmitter frequency range = 902 MHZ – 928 MHz Power = 25 dBm (316.2 mW) G = 0 dBi EIRP = 25 dBm (316.2 mW) R = 20cm Page 2 of 2 Power Density Requirement From table 1 (b) - Limits for General Population/ Uncontrolled Exposure of FCC Rule Part 1.1310 for 902 – 928 MHz S = f/1500 mW/cm​ 2​ (f = operating frequency) S​ req​ = 902/1500 = 0.60 mW/cm​ 2 Calculation: S = EIRP/4 π R​ 2 S= 316.2 /(12.56 x 20​ 2​ ) S​ ​ = 316.2 /(5024) S = 0.063 mW/ cm​ 2 ​ (<0.60 mW/cm​ 2​ ) This equates to a safe operating distance of 6.5 cm Signature: ________________________________________ Date: ___________________ 2020-07-08
